How to correctly charge lithium Ion battery of an electric screwdriver?

Charge at a temperature of 10 to 30 ° C. 1 time every 4 months, carry out a full cycle of discharge-rack for calibrating the charge sensor in the battery controllers. That is, discharge to almost 100% and put for charging for 12 hours. Store Li-Ion on the charge of 40-60%.

  • Remove the battery from electrical equipment (press the red/blue button at the bottom of the handle and, holding it, take out a jerk of the accumulative element);
  • Install the removed source in the charger unit;
  • Connect the power supply unit to the electricity source (outlet).

Features of charging batteries of different types

Below are the variants of the charges for various batteries.

Nickel-cadmium

In nickel-cadmium (Ni-CD) power elements are a rather high-speed “memory effect”. This should be taken into account by Bosch PSR screwdrivers owners. Therefore, they need to be discharged to zero. Otherwise, batteries will quickly become unusable.

  • Before starting the charging process, nickel-cadmium elements must be discharged.
  • Connect the charger and wait for it to turn off when the battery is fully charged. The indicator on the ZU will give about it to know.
  • In some cases, charging is not designed for auto shutdown. Then you need to wait for the end of charging and manually turn off the item.

Manufacturers sometimes allow themselves to cunning. On average, the nickel-cadmium element operates 500 hours. But in the instructions for a screwdriver you can often see the number “1000”. You should know that such a time will work only in conditions close to perfect. For example, Vinzor electric screwdriver will work less than 500 hours.

Nickel-metallological

These batteries also have a “memory effect”, although not as strong as the Cadmium. Nickel-metallogid (ni mh) batteries are discharged before charging until the end. Before starting work, it is necessary to charging five times and discharge the same amount of times.

Lithium-ionic

The very first undemanding and popular battery for electric screwdriver. “Memory effect” is absent. Lithium-ion (Li-ion) elements, new or former in work, can be charged at any time.

  • It is better not to put the fully discharged Li-and. It is desirable that the charge remains 20-40%.
  • The right charge temperature should be from 10 ° to 15 °. Since lithium-ion batteries are not afraid of cold, you can work with an electric screwdriver at a temperature of up to-10 ° C.

How long does it take for a full charge

Many users want to understand how much to charge the battery of an electric screwdriver by time. In this case, there are instructions for the tool or indicators on the charger. There is neither one nor the other.

The average amount of time to charge is 7 hours.

Domestic screws from Interskol, whirlwind, Ermak, Zuber require less time. Interskol is considered a universal electric screwdriver. It can be used as a drill. Tools of leading brands, such as Bosch, Dewalt, Makita, Metabo or Dexker, are charged faster.

If the power source needs to just be recharged, he is enough for half an hour. But do not do this with nickel-cadmium batteries. With their memory effect, they will quickly fail.

There are different modifications of charging devices. Ordinary without bells and grounds come with household screwdrivers. They have charging time. From 3.5 to 6.5 o’clock. But how much an electric screwdriver is charged with pulsed ZU also depends on the model of the tool.

The pulse charger is able to charge the battery for half an hour. This is a plus and minus at the same time. Minus in the high cost of such tools. The same recommendations are suitable for some automobile batteries.

Much depends on the power of the batteries. Household instruments may have 12 and 14.4th century. Professional models reach voltage from 18 V and above.

Instructions: how to correctly charge the battery of an electric screwdriver

Electric screwdriver is one of the most popular tools. It is noteworthy that with the help of an electric screwdriver you can not only screw and twist screws, but also drill holes. Electric screwdriver is good for everyone, however, the use of an electric tool creates inconvenience of a certain nature. The network is not everywhere, which interferes with the work, and the cord can interfere with an effective working process. In this regard, battery screwdrivers are becoming more popular, since they do not have the above problems. You can work with such tools anywhere, you do not need to look for a place where there is a socket.

Circuit of the lithium battery of an electric screwdriver.

One of the main elements of such an electric screwdriver is the battery, thanks to which the tool is able to function in autonomous mode. But with all its advantages there are also disadvantages associated with how to charge the battery.

Batteries for charging

Before you begin to charge the battery of an electric screwdriver, it is necessary to purchase new batteries. You still need to carefully read the instructions for the device. Batteries are different, the differences are containers, price and quality.

It is best to give preference to the most powerful batteries that are able to work for a long time. Experts recommend purchasing 2 batteries at once, then when working one of them there is an opportunity to charge the other. Often 2 batteries are included in the set at once.

Charger circuit for the battery of an electric screwdriver.

Among various batteries, nickel-cadmium and nickel-metall-hydride, as well as lithium-ionic. As for the 1st type of charger, they have large sizes, capacity and quite affordable prices. Charging can be effectively carried out at least 1000 times. But here it all depends on the features of the structure, operational regime and on how correctly the charging is carried out. The 2nd type of charging devices is good because it is absolutely safe from the point of view of ecology. As for lithium-ion batteries, they are good for everyone, but very poorly tolerate low temperature. This does not allow you to work with them in frosty weather. Despite the fact that charging is carried out very quickly, the capacity is high and it is easy to work with them, they are not very popular. They are too high prices.

In order for the charger to work longer and does not break, it is very important to correctly charge the battery.

Before using exercises for the first time, the battery should be charged, since during storage it usually has to be discharged. In order for the electric screwdriver to work with maximum efficiency, it is recommended to charge it first before work 3 times, after which it is discharged. The fact is that the capacity of the new battery is incomplete. You need to make it filled. After that, the battery needs charging as soon as the power becomes minimal.

If we talk about lithium-ion batteries, then using them is much easier. There is no memory effect there, which allows you not to bring them to complete discharge, but this type can be charged when it is required when it is required. For proper charging, it is necessary to take into account the optimal mode of the work process. It is strongly recommended that the ambient temperature is in the range of 10-40 ° C. It should be borne in mind that during such a process, accumulators can be significantly heated, but this cannot be allowed. The fact is that overheating of charging devices extremely negatively affects the quality of work, so it is necessary to cool it from time to time. As for the battery, it is strongly recommended to leave it in the charger. It is best to storage it separately, from an electric screwdriver it must be disconnected. If the use of an electric screwdriver is not implied for a long time, then recharging must be done about 1 time a month.

As for the purchase of batteries, it is recommended to give preference to those that are sold at specialized points of sale. We must not forget that only proper operation can largely extend the term of such a device.

The answer to such a question can be obtained in the instructions that are included. The information indicated there should be studied very carefully. Often, the charger is equipped with a special indication system, so you can easily understand how much the charging process is moving. It is very important to interrupt charging in time, otherwise the battery can easily be damaged. If we talk about the specific periods of charging an electric screwdriver, then they directly depend on the type of device, but on average it may take from 30 minutes to 7 hours. Charging current can be maintained due to the network adapter.

For the battery, you can use 2 types of chargers. Impulsive and ordinary. If we talk about a standard charger, then it is most often used among non-professionals, on average 3-7 hours are enough to charge the battery. For a professional mechanism, an impulsive charger is more suitable. Using it, you can expect that the battery will be charged in just 60 minutes.

Many people are wondering whether it is necessary to exercise the battery, if it is not used for a long time. Nickel-cadmium batteries must be discharged before storage, but you should not bring it to zero. It is necessary to bring to such a state so that the device can work, but not in full force. After long-term storage before the operation of the device, it is necessary to completely charge it 3-4 times and discharge it.

Nickel-metallological batteries are strongly recommended to be stored in a charged state, and after they have not been used for a long time, the charging process needs to be carried out at least a day. If we talk about lithium-ion batteries, then they are recommended to be stored in such a way that they are charged by about 50%.

If such a situation is observed, then there may be several reasons:

  • Wear.
  • Malfunction.
  • Violation of the contact between the terminals of the battery and the charger (here it is not difficult to correct the situation: you just need to disassemble the charger and bend its terminals).

The impact of external factors on the battery

In the kit, each screwdriver necessarily applied instructions on how to charge the battery. In particular, this applies to expensive models. In this case, the process can be performed both indoors and in street conditions.

Additional Information. Charging nickel-cadmium power sources with capacity indicators of 1.2 a h will take about 7 hours.

Before putting an electric screwdriver for charging, it is worth considering a number of important nuances. It is necessary to avoid direct contact of the power tool or its battery with moisture in any form. Rain, snow, high humidity level. This inevitably leads to a violation of electrical conductivity, including the development of rust.

The impact of direct rays of the sun also destructively affects the state of both the battery and the entire tool. This is especially true for the period of summer operation, when the air temperature rises to 40, or even more. Result. Overheating of the device, violation of electrical contact. This process cannot be immediately noticed and the symptoms will appear over time.

Instruments

Among the power tools, both household and professional, electric screwdriver is one of the most popular. With it, you can not only twist and screw screws, but also drill holes. Tools feeding on the network can be used not always and not everywhere, and the cord all the time interferes with the work. Battery screwdrivers are spared these shortcomings. You can move freely with them and not depend on the presence of a socket in the room.

An important element of each battery is a battery that allows you to work autonomously with it. This is very convenient, but sooner or later before each owners of such a power tool the question arises of how to charge the battery of an electric screwdriver.

Types of batteries used for the operation of an electric screwdriver

Before purchasing new batteries for an electric screwdriver, you must carefully study the instructions for the device. The tools necessary for work can be professional, domestic and semi.Professional. The batteries differ from each other with a capacity, quality and price.

Certain types of batteries designed for different loads are also intended for certain work, therefore, batteries are needed for them different. The larger the battery power indicator, the longer it can work out. For convenience, it is better to have two batteries so that you can recharge the second when working with one. Often the second battery is already included in the kit when selling a tool.

For screwdrivers, you can use various types of batteries. Most often, nickel-cadmium (Ni-CD) and nickel-metal-hydration (Ni-MH) are used, and recently-also lithium-ion (Li-Ion).

How to correctly charge and store batteries on screwdrivers, battery tools 2020

The most common of them are nickel-cadmium batteries, characterized by compact dimensions, large capacity and acceptable price. These batteries can be effectively charged more than a thousand times, depending on their design, purity of materials, operating mode, including the correct charge of the charge. However, these devices have the so.Called memory effect, and if they are charged without waiting for complete discharge, the battery capacity will gradually decrease. In addition, the production of such elements is so toxic that the European Union on its territory refused it.

In second place in terms of frequency of use-nickel-metall-hydride batteries representing a new generation of such devices. From the point of view of ecology, both the production and disposal of these nutrition elements are practically safe. The advantages of the batteries of this type include that they have less pronounced memory effect, and to the minuses. High current self.Discharge. These batteries need to be stored charged, and when interruption in work exceeding the month, they need to be completely reloaded.

Not so long ago, more powerful lithium-ion batteries began to use for battery tools. They also do not have the shortage of the effect of memory that requires the capacity of periodic discharge cycles to restore the capacity. However, these batteries do not tolerate low temperatures, and it is undesirable to work in frosts with them. Despite the fast charge and high capacity, they are not yet very popular, since their price is quite high.

What to do if the battery of an electric screwdriver is not charged?

If the battery of an electric screwdriver does not charge, perhaps the reason should be sought in its wear and tear or in the faulty operation of the charger. However, the problem is often a violation of contact between the terminals of the battery of an electric screwdriver and a charger, since over time they are extended. In this case, you can disassemble the charger and bend its terminals.

In addition, after a while using the battery contacts, and contacts of the charger can be oxidized and contaminated. Even minor changes in this kind can interfere with normal charging batteries. This is usually expressed in a significant decrease in both charge time and the duration of the battery power tool itself. So that this is not, it is necessary to periodically wipe the contacts of the battery, the charger for the battery of the electric screwdriver and the tool.

Unfortunately, the characteristics of the battery elements worsen over time. So, with improper operation of nickel-cadmium batteries, most often used in household models of screwdrivers, they quickly lose the capacity. Experts sometimes advise to “disperse” such batteries. The battery block is disassembled, and problematic elements are determined. After that, their charging is required. How much to charge the battery of an electric screwdriver in this case? Experts recommend first charge such elements with large current than it should, then discharge them and charge them again, but in small current. If the electrolyte has not yet evaporated in the Ni-CD batteries, such a “therapy” may help return them to life.

In addition, you can restore one battery block of two, partially lost the container, choosing entire “banks” from them and soldering together. After that, to align the charge, it is necessary to completely charge and discharge the restored block several times.

The reason is also that the battery does not charge, it may be in the temperature sensor
