At present, we commonly used batteries are divided into three categories, namely, ordinary batteries, dry-charged batteries and maintenance-free batteries.


1) Ordinary battery; Ordinary battery of the plate is composed of lead and lead oxide, the electrolyte is sulfuric acid solution. Its main advantage is the voltage stability, cheap; disadvantage is lower than the energy (that is, per kilogram of battery storage of electrical energy), short life and frequent maintenance routine.

2) dry charge battery: its full name is a Dry charged lead acid battery, its main feature is the negative plate has a high storage capacity, in a completely dry state, can be stored within two years of the electricity, the use of , Just add the electrolyte, such as over 20-30 minutes can be used.

3) maintenance-free batteries: maintenance-free batteries because of their structural advantages, the consumption of electrolytic solution is very small,Within the service life of the basic don't need to add Add supplementary fluid water. It also has shock-resistant, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery. Maintenance-free battery on the market there are two: the first one in the purchase of electrolyte after the one-time use does not require maintenance (Add supplementary fluid); the other is the battery leave factory itself has been added electrolyte and sealed , The user simply can not Add supplementary fluid.
