If your battery gets worse, you don't always need to dispose of it right away. Try to extend his life and revive him! A good effect can be given by the buildup (training) of the battery. To do this, perform three charge cycles and then deep discharge.
Instructions
Step 1
When servicing the battery, in addition to charging, you sometimes have to perform a forced discharge. This must be done during the training cycle in order to "swing" the battery, as well as in order to determine its working capacity, which in a given technical state is available in the battery.
Step 2
If the battery cannot withstand training, try to revive it with a three-hour recharge or use a training discharge-charge cycle.
Step 3
To discharge the battery, take two old bulbs (low and high beam). They must necessarily have at least one intact filament.
Step 4
Turn on these lamps in parallel and connect to the battery after charging it. As a result, you will get a complete imitation of the included headlights of the car.
Step 5
Observe on the clock how long the first discharge of the car battery lasted until the time when the filaments turned crimson.
Step 6
Immediately put the battery on the next cycle - charging. Do such manipulations three times.
Step 7
Compare the duration of the final (third) discharge cycle with the time it took for the first cycle.
Step 8
If you notice that the time has changed in the direction of increasing by somewhere between 20-30%, this means that your battery "came to life". If the time remains the same, then you will have to part with such a battery.
Step 9
If you know what a tester is, you can use it to determine the approximate estimated time that was spent on the discharge. For this purpose, measure the discharge current in the very first minutes, and then divide the battery capacity by the amount that the discharge current has. As a result of these actions, you will find out the approximate duration of the absolute discharge. This will help you to correctly navigate the execution time of all cycles.
Step 10
The battery can be discharged overnight. Then by the morning, you will be ready to catch the moment of full discharge in time.
Step 11
Do not keep your battery completely discharged for too long. You can charge with a light bulb for an unlimited time.
