Repair of the battery casing is cracked hull after the accident battery 'Trepca'. In the repair of a battery is not accepted, throw a pity, but you can not operate because the flowing electrolyte. Trying to patch up crack soldering iron did not produce results, the electrolyte has continued to trickle out. This problem, we decided to (do not be surprised!) With dichlorvos in spray cans – means for destroying household insects. Electrolyte leaked, carefully washed surface cracks and battery soda solution, then with distilled water and dried, so that cracks do not remain wet. Wetted dichlorvos space leakage of electrolyte, and when the plastic softened, filled the cracks previously prepared a mass of finely planed polystyrene dissolved in dichlorvos. When the plastic hardened, the surface of the battery was washed with soap and water and electrolyte filled.

After repair of battery is the second year. When you work should follow the precautions listed on the label of the cartridge. taken from the auto book Conductive film on conductive film from the battery electrolyte battery can not be detected only indirectly, by the rapid self-discharge, but with a voltmeter or avtotestera. One end of the probe set on the battery, observing polarity, the other wire from the opposite O on the surface in the direction of the first. If the surface is clean, then the readings should be zero.

Otherwise the device will self-discharge voltage, which will decrease the closer one to probe another. Self-discharge of the battery installing a new battery instead of domestic production had served six years of Bulgarian, I noticed that she is losing capacity in the parking lot. Hence, high self-discharge or the leakage current. To determine the cause disconnect the battery and measured the current between the terminal 'plus' and the body ('mass'). He was found to be 7.5 mA. Per month capacity is reduced by about 10%. The only way to leakage are details of the battery mounting. I insulated it with vinyl chloride and rubber tubes so that it is nowhere tangent to the metal. Due to this leakage current has fallen to 30 uA. And when the surface is covered 'Movilem', leak nearly vanished. taken from the car book
