The accumulator battery (storage battery) is perhaps one of the most important parts in the equipment of a car. She is responsible for starting the engine in any conditions, for all electrical components and devices. On injection engines, the state of the ECU (electronic engine control unit) also depends on the correct operation of the battery, because with electronic fuel injection, the battery evens out the voltage surges that appear during the operation of the generator.
It is necessary
Distilled water, syringe, glass tube with a diameter of about 5mm, charger from 0.05-1.5A
Instructions
Step 1
First you need to measure the electrolyte level. To do this, unscrew the plugs on the top surface of the battery (a wide screwdriver works well), insert a glass tube the size of a ballpoint pen into one of the compartments and submerge it on the bottom. Cover the upper opening of the tube with your finger and pull it out, the electrolyte level in the tube is equal to the level in the battery (norm 13-15 mm), if higher, then it is worth sucking out the excess electrolyte with a syringe, lower - it means it's time to top up with distilled water.
Step 2
Suck clean water into a syringe and add 5-10 ml to each of the six sections of the battery. Thus, to achieve the desired level of electrolyte in the battery.
Step 3
Take a special charger, connect it to the battery without closing the plugs. This is necessary if there is an excess of electrolyte, it will have where to leak out. First, charge and discharge the battery 3-4 times to restore capacity. Then set the current on the device for charging at 0.1A and monitor the voltage at the terminals. Do not allow the battery to boil or overheat; if necessary, reduce the charging current. Normal voltage when fully charged should be 13.9-14.5V. Then reduce the current to 0.05A and continue charging. If during the next 2 hours the voltage remains unchanged, stop charging!
Step 4
Close the covers. For greater reliability, the battery should withstand approximately 12 hours. Then start exploiting. The battery is ready for use!
