Maintenance-free battery due to its structural advantages, the consumption of the electrolyte is very small, in the service life of the basic don't need to add distilled water. Maintenance free storage battery voltage is 2 v, usually the three lead battery used together, the voltage is 6 v. Cars with six series lead battery into the 12 v battery pack. Ordinary lead-acid batteries in use after period of time to add sulfuric acid, keep the electrolyte contains 22 ~ 28% of dilute sulphuric acid. Maintenance-free battery service life generally for twice the normal battery. The free maintenance battery on the market has two kinds: the first in one-time add electrolyte later use when buying does not need maintenance ( Add supplementary liquid) ; Battery itself is another good factory had already added electrolyte and block, users won't add supplementary fluid. Common battery plate is made up of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. It is the main advantage of voltage stability, the price is cheap; Defect is lower than can ( The battery storage of electricity per kg) , free maintenance and daily maintenance and short service life of battery frequently.
