Handyman tips on how to properly service a maintenance free battery

Long gone are the days when you just plugged the battery into the charger and left it on overnight. For example, a fully discharged battery with a capacity of 50 ampere-hours should be charged at 5 amps for ten hours. Charging should take place with the caps removed or the plugs removed. You can’t charge the battery too fast either. This can lead to overheating or even boiling of the electrolyte.

About Topla

Production of Topla batteries is carried out by TAB Tovarna Akumulatorskih Baterij D.D. It is a European company with production facilities in Slovenia and Macedonia.

The company is one of the world’s leading battery manufacturers. Since the 70’s the equipment was supplied to the markets of the USSR, used in the automotive industry as well as in industrial enterprises.

At the beginning of the new century, the company underwent a real technological revolution. Modern technologies have come into play, the approach to work has changed, and the amount of work performed has many times increased.

Where Topla batteries are used

Today, TAB manufactures industrial and automotive batteries of all types. On the official website of the Russian representation of the company you can see their full range.

During the times of the Soviet Union they were actively supplied to the energy, communication enterprises and other objects. Today, a large number of varieties of lead-acid automotive starter batteries are produced, which are supplied almost all over the world, including our country. You can buy them in specialized stores of Topla dealers.

How to open a maintenance-free battery

There are not many ways to open the power supply of closed type, and they depend on the goal. If you need a lead (for hunting or fishing), then you can not worry about how to open the battery, and just break its case.

In order to extend the life of the battery, it is necessary to make holes that will give access to the banks.

  • Remove stickers from the surface of the battery.
  • Carefully inspect the case. Since the battery is sealed lead-acid battery was poured at the factory, the plugs remain stamped.
  • Take an awl, a screwdriver or a drill and carefully make holes in the place of the floods.

This simple procedure requires some care, but it allows you to restore the performance of an existing battery instead of buying a new one.

Repair with your own hands. how to repair the battery correctly

Once you get to the electrolyte, you need to check three parameters:

  • Color. Make sure the electrolyte is clear and free of debris. Destroying lead plates give the fluid a dark color.
  • Level. Evaporation of water causes the electrolyte level to drop, reducing capacity. Each battery has its own parameters of the liquid level, but for all batteries the plates must be immersed in electrolyte.
  • Density. It is checked with a special device. areometer. Density of electrolyte in a charged battery is 1.27.

Important! Wear personal protective equipment when handling electrolyte! Wear glasses, protective gloves and a respirator. Splashes of electrolyte in your eyes or on your skin will cause chemical burns.

The procedure for diagnostics of the maintenance-free battery is as follows:

  • Check the voltage of the battery and the car onboard network. This is necessary to avoid chronic undercharging of the battery. On short frequent trips the battery does not have time to charge, with a decrease in temperature the capacity drops by 20. 40%. Many owners blame quite working equipment, although it should be used properly.
  • Charging the battery. It is preferable to use a factory-made battery charger, preferably with a controller. Use of electronics will increase accuracy of charge. If the charger is simple. set the current to about 0.1 of capacity. A 60 Ah battery should be charged at 5 to 6 Amps. charging lasts. until the reading on the ammeter will decrease to 2-3 amps. Strongly discharged battery should be charged with 1-2 amperes current (about 1/20 of the capacity) for several days. The voltage must not exceed 15 volts, otherwise the jars will “boil” and can swell.
  • Drill holes in the battery cover. We check electrolyte level with improvised dipstick. If the battery case is made of light-colored plastic, you can check the level by shining a flashlight through the battery.
  • Check the density with a areometer.
  • After checking and refilling the battery close it tightly.

How to correct the condition of the electrolyte

Three variants of correction of electrolyte density are possible:

  • Low density at normal level. Take out with areometer all the content of the jar and pour it into the glass container. We add concentrated acid, we bring the density to the recommended density. Add electrolyte to the level in the can.
  • With low electrolyte level, high density. Add distilled water, stirring the electrolyte with a glass rod. After work, measure the density.
  • At normal level, high density. Drain the electrolyte, add distilled water, top up.

Important! The density of the electrolyte is its main characteristic. The entire battery operation depends on keeping this parameter in a normal range.

For battery maintenance, all electrolyte may be poured into a glass or enameled container, stirred and the density checked. Pour normal electrolyte back into jars; if low, top up with fresh, high-density electrolyte. The battery should be topped up evenly in all jars so that the amount of fresh sulfuric acid is equal in all jars.

Operation after service

After opening, the maintenance-free battery loses its sealing properties. It’s best not to use one if the construction is upside down or standing in the car’s interior.

Any tampering with the labyrinth cover will result in loss of distilled water vapor trapping and condensation properties. Repairs turn a maintenance-free battery into a serviceable battery. You’ll have to look in the battery more often.

It is necessary to finish the maintenance of the battery by charging. It is discharged by connecting a few consumers and then recharged. With low currents. After two or three charging cycles it is advisable to check the battery with a loading fork. If the capacity of the battery has dropped drastically, you should decide to replace it.

Review: Bosch S4 005 60Ah Battery. Not the worst.

After buying a used car, drove only a week and the starter suddenly stopped cranking. I got the details from the previous owner. Turns out the battery was switched by an intermediary in the sale. He drove a good one to the car market, but put an old Turkish one at the checkout. I could drive this one for a while. Only the electrolyte turned out to be regular tap water. It gave me a big self-discharge. The reseller apologized and shook his hands. He gave me a good discount. Also, as it turned out, he replaced the more expensive car stereo with a native one. As I noticed the tires were also from the cheaper ones, but not worn out, you could still ride. All in all, the discount was enough to pay me back twice. And for the purchase of new tires, radio, oil and filters and the battery also left a good amount.I went to pick them out. The store I was recommended specialized in Bosh. There’s about ten kinds. Consulted with the seller. He specified the model of the car and recommended a few of them. I settled on the S4. I put it in, started it up. The seller took a couple of measurements to write the warranty. It’s not uncommon for an alternator to go out of service. This is especially true for used cars with considerable mileage, like mine. The brushes can wear out completely over time. It’s also not uncommon for the diodes in the voltage regulator to get punctured. The starter is not out of order. All of these cases can lead to unnecessary replacement of the battery. Just recently there was a case of. Car won’t start. The owner immediately replaced the starter and battery. He started it twice, and that was it. I advised him to look at the alternator. He replaced the alternator repair kit. It’s got brushes and a voltage regulator. Everything worked. The repair kit costs 50, but the entire alternator costs 200. It’s worth the trouble. It’s more time-consuming, though. It turns out he changed the battery for nothing. That’s why salespeople measure the values on the battery terminals to get a warranty. He is not interested in what the battery produces, but the parameters of the state of the car’s electronics. He took a few measurements in three minutes, said OK and wrote a warranty.

Later it turned out that not everything is perfect.

Release date:The first thing that came out was that my battery had already been dusting in the warehouse for a year before it was sold. They just charge them up before putting them on display. Which, by the way, the salesman didn’t hide when I asked to measure the voltage on it before installing it in the car. The voltage reads 12.6. it’s OK. On Bosh, instead of writing the date in a normal human format, they twist the codes, which salespeople without special tables can not decipher! It’s a three-digit number stamped on the side wall. For example the code 006 means June 2010, the code 460. December 2014. How can this be deciphered to an unfamiliar person?It turned out that you can find batteries that have been on sale for more than three years. It’s no longer new, but to take to throw away. We don’t know what conditions they are stored in. Almost certainly the warehouses are unheated. Who is going to heat the room where they store mountains of batteries? There can be a buildup of fumes and you need to ventilate all the time. And lay in the freezing winter without recharging. half of its life is gone. Now I made myself a sign so I don’t fall for such tricks again. Year of the Bosch battery.

It has served me well, helped out at least once and maybe a few times at a friend’s house. Not to buy an old new battery.

Lifetime.My Bosh S4 battery lasted me five years and four months without a problem. At the end of another winter, it suddenly failed. Suddenly did not want to start the engine, although there was no frost that day, about zero. I gave it half a turn and that was it. I had to jump start the engine and leave it running for half a day until I bought a new battery. Now in order: After half a year of operation, I have managed to completely drain the battery on vacation. Not a single light was on in the car. From a push start, on the third gear was able to start. After that it recharged itself on the car. Got to a full charge with the charger after two days. After 8 months, after a winter check. Surface testing showed that the battery had about two thirds of a charge. It does not want to draw any more current from either the alternator or the chargers. No way to check the electrolyte level and composition as there are no service plugs. I had to drive it the way it is. I kept monitoring the voltage every quarter. After 8 hours of parking, with the engine not running, measured the voltage. When fully charged it should be 12.7 volts at 20 degrees. At other temperatures there is a slight correction. When it dropped below 12.5 volts I took the battery off and charged it. After recharging, it stayed new for a while, about a month. Then it would go down to 12.55. 12.6 and stayed at that level. A little lower on short trips, a little higher. On the long haul. Doesn’t fully charge on its own even if you drive all day from one startup. I think my alternator is to blame here. It has a built-in voltage regulator, it seems it is not perfect. The optimum voltage should be somewhere around 14.2 volts. But it is because before there were no calcium. It is better to raise a little to 14.4 V. And my alternator is giving out like this. In the cold in the.20 it gives 14.6V for one minute. Then it drops to 14.2 and when the engine is fully warmed up it is only 13.9. So it does not have enough voltage to fully charge, even if you drive a long time. The body of the alternator heats up on its own and heat is transferred to it from the engine, both through the air and through the mount. It’s the heat from the alternator that’s affecting the voltage. On purpose or accidentally, I do not know. Maybe just the voltage regulator itself, warming up, gives less. Or if this is done on purpose, so as not to boil the battery in the summer. Then there should be a temperature sensor installed near it and not inside the generator. Otherwise it makes no sense. The main problem is that Bosch is obsessed with adding calcium to the lead plates. That’s both good and bad. That said, the acid boils less in the summer. But the scary catch is that now the battery can’t be discharged, especially completely. It will never fully charge again. No matter how fancy chargers you use. The basic question is: How do you use a battery without discharging it?!? What else is it for?? So there’s a charge, but you can’t use it. If all the equipment can only be turned on on the road, you lose the comfort of the car on parking lots and on vacation. Well, that’s just some kind of “uncomfortable” battery. Out of the claimed 60 amp hours you can only use 20 and then each time” reducing the life of the battery by a couple of months. You can only put one of these on a small truck or something. Where the driver does not think about comfort and drives only on long trips. What about the other 40 amp hours?? They are decreasing with each cycle of partial discharge and charge and you just don’t know it. At a certain point. bam! and the starter became. That’s what happened to me. It turns out you carry a charge that can not be used or can only be used in an emergency. I drove 5 years not knowing what’s going on inside the battery. Only had one discharge. After that, I used it as carefully as I could. How else can you assess the condition other than voltage if there are no plugs? Tried to shine the white hull with a bright beam of light, nothing could be seen. Tried to minimize power consumption at parking lots, it went only for the alarm. Before important trips there is no certainty, you do not know at what point you will be, when the starter will stop cranking.With this operation, I probably would have gone another winter with it if not for one unpleasant moment. In the first cold weather I could not start the engine. Decided it just needed to be warmed up and started it with a tow. It was hard, but it worked. I stalled at a stoplight in heavy traffic. I had to drive the starter out of the way. Then it did it for a long time, but I couldn’t start it. So it almost gave out. And it didn’t spin for long, it was clear that the battery didn’t have long to last. The cause turned out to be in the wiring, or more precisely, in the cap of the peddler. It was enough just to wipe it from the inside of the condensate and the engine easily started on a nearly dead battery. After that, I drove all winter without any problems. With frost up to.♪ 20s ♪. Didn’t even remember the incident again. As soon as it got warmer, it wouldn’t start. Almost suddenly, a couple of very sluggish turns and all. Tried to charge twice, no effect. And with pulses and long exposures. Just started it twice and that was it. Got it started and went to get a new one. My mistake was that I didn’t fully charge the battery before winter, after the time it went dead. I didn’t watch the car very well that winter. There was heavy icing, the doors couldn’t be opened, and it just didn’t get to the inspection of the engine compartment. Here it goes. This time I got the Turkish Halk. Just because it has maintenance covers. Although it’s also calcium. I’m not at all sure that it will last 5 years either, we’ll see. The winter has just begun and already cranks sluggishly, even the light bulbs sometimes blink. Hasn’t served a year yet. The issue date was fresh at purchase, just brought in. The voltage is 12.6, they took the package off in front of me. There’s another thing about Bosch. At the bottom, the mounting bead is lower than usual. I had to put a thick piece of rubber to keep it from falling apart. No complaints about the workmanship. I think the technology itself is to blame. And this particular calcium with all its pros and cons. I almost took a helium Bosch battery this time. They promise a lifespan of 10 years. But that’s also very doubtful. Even the helium Bosch also has calcium plates. So they can’t be discharged either. But I didn’t get it for another reason. They just wanted to sell me a used one as if it were new. Thanks to the chart above, I didn’t fall for it. It was three and a half years old. After the date, noticed that it is unpacked, the contacts are lightly but carelessly scratched. Wasn’t too lazy to pick it up and look at the bottom and there’s a lot of scratches. Someone used it for three years and decided to change it.

How to check the electrolyte level

You have two ways to check the electrolyte level in the maintenance-free battery: by the marks on the construction and by the indicators. Let’s consider each one separately:

  • The abbreviations “max” and “min” tell you the charge level. It is written on a window reserved for this purpose. The indicator in the middle of the window tells the owner that the battery is fully charged. Sometimes there is no window, but the manufacturer leaves the transparent part of the body, which is usually made of plastic, for identification.
  • Indicators. Some developers have chosen this option, which also perfectly clearly tells the driver the level of electrolyte. How they do it? The answer lies in the color produced directly by the indicator. The range of colors is limited to green, white and red. The first tells you that the battery is fine and there’s nothing to worry about. The second. that it’s time to put the battery on charge. And the third color indicates the critical state of the battery: it is displayed when the acidity has increased and the water level has dropped. Of course not all models use these colors, so check the manual beforehand.

As we’ve already told you, there is no reliable source, so all figures are approximate and it’s best to pay attention to the indicators more often. Sometimes the malfunction of the battery depends on the fact that the level of distilled water in the battery has dropped

Battery maintenance-free type, as evident from the name, does not provide a hole for external intervention of the owner to fix this failure. But there is one way. So, how to add distilled water to a maintenance-free battery?

bosch, battery, open, cover

Sometimes the malfunction of the battery depends on the fact that the level of distilled water in it has dropped. The battery of the maintenance-free type, as can be seen from the name, does not provide an opening for external intervention of the owner to fix this failure. But there is one way all the same. So how do you fill a maintenance-free battery with distilled water??

  • Firstly, in any case do not remove the battery cover: it is so fixed that you probably will not be able to put it back. So just take off the sticker.
  • Secondly, through the transparent areas we find the banks and baffles. With the help of this picture we determine where to fill up with water or check the density of the electrolyte.
  • Carefully make the passage, using a tool like an awl.
  • Now through the passage in the jar, where there is a density indicator, pour water in 5 ml. For your convenience, buy a disposable syringe for this operation. When the light turns white or green, add 20 ml more.
  • The electrolyte level is easier to read if you have a transparent battery case. Otherwise, resort to this method: immerse the syringe with the needle in the can and pull the stem toward you. The moment the electrolyte begins to flow into the cavity of the syringe, make a mark on the needle.
  • Next, you need to refer to this mark when you add water to the remaining jars.
  • You can seal the holes you’ve made with sealant, or you can cut a kind of plug out of rubber.
  • Shake the battery a little to mix the newly distilled water.

How long to recharge a dead battery?

Unattended battery is good, but if you kill it once to zero, then after that he almost dead (especially in winter).

Dream. Never failed on FORD. Charging once every six months, as a precaution.is now on a kopeck.

Maintenance free doesn’t mean it’s not rechargeable!

Hello please tell me, I have the same battery and charger, a year ago also did this procedure all ok, but there was a different battery.I’m plugged in now, but the diode that’s supposed to blink just blinks on and off?or does it start flashing later?the self-diagnostic test shows that the battery.it works.And it doesn’t get too hot in your car, either?

I, on this particular charger, didn’t blink one of the lights only changes color. To be honest I charged once now and do not really remember.)
