When problems with the battery begin in the car, you cannot hesitate. After all, the consequences can be sad - at the most crucial moment, the engine will not start. Thus, a situation will be created that is dangerous both for the driver of a faulty car and for other road users. The battery needs urgent replacement or repair. One way to recover is to flush the battery.
Necessary
- - hydrometer;
- - loading fork;
- - rubber bulb;
- - a container for draining the electrolyte.
Instructions
Step 1
Determine the need for flushing by the following factors: 1. The color of the electrolyte has changed (from pink to brownish) 2. When charging, the rechargeable battery is quickly charged to a full charge, and also quickly discharges during operation. This means that the capacity of the battery has changed - it has become smaller. Possible causes are salt deposits (sulfation) or self-discharge of the battery. Due to contamination of the battery surface, the insulation resistance of the cover is disturbed, current leakage and self-discharge occur. 3. When checking the voltage at the battery terminals, the device shows zero or a figure close to zero. This means that due to the large amount of the formed sludge that fell to the bottom of the active layer of the plates, an overlap and short circuit of the battery plates occurred. battery life, get to work.
Step 2
Flush the battery after discharging the battery. Use a rubber bulb to suck the electrolyte off and drain it into a glass container (for further disposal). Fill with distilled water instead of electrolyte. Repeat the process until there is pure distilled water in the jars. Leave the battery with water for two to three hours. Drain off the water using the same rubber bulb. Add electrolyte to jars and bring its density to 1, 2.
Step 3
Charge the battery. Charge until the battery voltage and electrolyte density become constant. After that, bring the density of the electrolyte to normal (it depends on the ambient temperature).
Step 4
The most difficult case is the closure of the plates by crumbling sludge. In order not to aggravate the situation, it is not recommended to shake the battery, turn it upside down, etc., so as not to raise this sludge from the bottom and cover the plates with it. This flushing is done during a major overhaul of the battery. Cut out the short-circuited "jar", remove the sludge from the body with a rubber bulb. Rinse 2-3 times with distilled water. Replace the plate section, repair the battery circuit. Using mastic, seal the lid.
