screwdriver is a necessary tool in the economy, but the time comes and the energy source - the battery stops working.Models are constantly changing and sometimes find the battery fails.However, it is possible to fully restore or prolong service life of 2-3 years.For information on how to repair the battery screwdriver, says this article.
Dismantling battery
addressing the issue of whether it is possible to restore the battery screwdriver, it is necessary first of all to figure out how to remove it from the elements.The battery is housed in the plastic case from two halves.First you have to unscrew the connecting screws.If the connection is made with glue, it is necessary to tinker with a screwdriver or chisel.Disassemble should carefully so you can seal the casing again.
placed inside the cells connected in series.Some designs use a parallel-serial connection.
Replacing the
When deciding on how to restore the battery screwdriver, it is necessary, first of all, to identify defective cans that spoil his work.If the battery is dead, it should be charged, and then check the voltage on all the elements.It should not differ from the nominal not more than 10%.
repair is how to restore the capacity of the battery screwdriver in general.It is influenced by the serviceability of each element.He must be given the capacity, which is understood as the ability to feed connected loads.Sometimes it is better to replace defective elements, which quickly discharged.They can be detected by shock or the presence of corrosion on the surface of specific traces of electrolyte.
one or two elements can be a serious obstacle in the entire line.
If the battery is used for more than 3 years, the problem may be most of the elements.In this case, better to replace them all.It is important to fit the voltage and size.The cost of batteries collected separately is lower than the new assembly.
regularly every largest banks check the internal resistance, which should be about 0.06 ohms.For this purpose it is connected to the load (resistor 5-10 ohms) and thus determine the current and voltage.It is convenient to apply the low-voltage incandescent lamps.The measurements are taken with two different resistances were respectively 30% and 70% of the allowable load.From 1st voltage subtracted 2nd and 2nd of current - 1st.The results are then subtract and divide, according to Ohm's law, we find the internal resistance of the battery.
battery is often sold bundled with a spare.Of the two, you can collect one and will remain in the reserve banks.Their desirable somewhere to use as a power source, such as a flashlight with auto lamp.
After the diagnosis authenticated elements come in the line.Collated need to solder in the same manner.Housing Bank has a negative polarity, and the average bus - positive.Then, without assembling the battery, connect it to the charger.Thus it is necessary to control the temperature of the elements.If they are correct, then the strong overheating should not be.At the end of the charging time, and a day on each element should measure the voltage.If any of the battery "gets" more than 10%, it needs to be replaced.After the battery test will take place, it is possible to collect the body completely.Fixing screws are screwed into place according to the size, and as an adhesive used acetate-acrylate ("super-glue").With proper selection of elements of the battery will serve as new.After charging it should be subjected to intensive training, creating maximum load screwdriver until it is discharged.Such cycles should be repeated 2 more times, and then - 1 time per quarter.
Recovery cans
unauthenticated batteries do not need to rush to throw away.The main reason for their failure is the evaporation of water through the elastic sealing disposed between the housing and secondary tire.When it's full, "zero", the battery charge, briefly pulsed voltage supply 12 through a resistance of 40-50 ohms.It should be controlled to the body does not overheat.If after that it still does not stress, the bank can be discarded.
To restore electrolyte, some craftsmen in the lateral recess of the battery battery drill hole mini-needle syringe.Then the cans are filled with distilled water.When the batteries need to lie down during the day.The battery then "train", charge and check the voltage on each element.The holes are sealed with silicone.
How to restore the battery screwdriver
batteries inside all to look alike.They consist of sequentially welded cans.The result is the total battery voltage at the output terminal.Elements used the following types:
- Ni-Cd (nickel-cadmium, U = 1,2 V).
- Ni-MH (nickel metal gidritny, U = 1,2 V).
- Li-Ion (Li-Ion, U = 3.6V).
Battery screwdriver "Interskol"
Screwdriver "Interskol" is one of the most popular due to its versatility.Besides the main function it can also serve as a drill.Batteries it can be any of all common.Nickel-cadmium and metal gidritnye often used as a cheap and powerful enough.In order to function reliably, they must be before the end of discharge and recharge, to make full use of the charge.Otherwise, the service life of equipment is greatly reduced.Reversible loss of cell capacity at partial charge and discharge memory effect.
Lithium-ion batteries do not have this disadvantage, but have a much higher price.During operation, when every minute counts often require a small additional charge to maintain the required power screwdriver.Here, like the batteries are irreplaceable because their capacity can be quickly restored.
battery screwdriver "Interskol" buyer chooses their own, depending on the preferences, capabilities and work required.In most cases the use of nickel-cadmium batteries.
How to restore the battery screwdriver "Interskol" if it is not used for a long time?In operation, it is necessary to try to ensure that the voltage drops to zero was not.For banks in the discharge of produced 1.2 to 0.9 V. If the long-term storage, it is completely discharged, the charger can it not "see."It is necessary to "push" the battery by another, more powerful source of power to her there was a small voltage.After that you can connect it to the standard charger.
Restore battery screwdriver "Makita"
Before you restore the battery screwdriver "Makita", you first need to disassemble the cabinet.It consists of 2 halves are connected with glue.If carefully obstuchal battery housing with a rubber hammer, glue lag behind.In some places, there may be problems with disassembly.They may need additional hand tools.Next, be sure to disconnect halves of the case, holding the terminal with a screwdriver.
in performance drill "Makita" approaching networking tools.Independent power supply provides two removable Li-Ion battery.Computer technology allows them to restore the charge in just 22 minutes.Thus the battery life is considerably increased.
defective cans must be replaced by similar new models.If they are hard to find on sale, will have two batteries to collect one.Factory welding can be a contact, and the repair will have to create a solder connection.
How to restore the battery screwdriver Bosch
Screwdrivers Bosch are ideal for non-professional use.They are equipped with batteries Ni-Cd elements.They withstand high load currents, but quickly self-discharge (3-4 weeks).Not less than 1 time per month they need to rebuild, not to have failed.Furthermore, during operation occurs unbalancing elements and eventually lost capacity.
One way to restore the building and dismantling of a "workout" each element separately.If this does not help, some of them have to be replaced.Then the battery will last for a long time.
Restore battery screwdriver Hitachi
How to restore the battery screwdriver Hitachi?Both Ni-Cd battery, you must charge, after which they must be disassembled and measure the voltage of each bank with a load of 1.5 ohm.Elements showing less stress, you can throw it away, but from the whole assemble a high-quality battery.A total of 1 or 2 banks can spoil the impression from the battery.How to restore the battery screwdriver "Hitachi", as well as all other models depends primarily on the type of components installed in them.
Restore battery screwdriver Aeg
Complete with a screwdriver 2 batteries sold in the Li-Ion cells.If one of them is not charged, it is not talking about his faults.It may be that he is too deeply discharged.To do this, you can try "to practice" battery supply voltage pulse to it, and then put in charge.The easiest way is to connect a few seconds to a charged battery.
After restore battery screwdriver Aeg above method fails, the casing must be disassembled to check each jar.
Maintenance Guidelines batteries
- If the battery is not used, once a month should be allowed to discharge the load and recharged.
- advisable to buy a screwdriver with two batteries included.
- screwdrivers should be stored and used under conditions which exclude moisture.
Conclusion
How to restore the battery screwdriver?There are several ways.Before its dismantling, we must try to find the cause of the problem, which can also be a mechanism or charger.Observing the rules of operation of the battery contained in the instructions, you can greatly extend its operation.
