One. According to the use of lead-acid batteries, they can be divided into:

　　1. Starting battery: mainly used in automobiles, motorcycles, ships, ships, etc.

　　Such as: 6-QA-60AHQ---for starting.

　　2. Small traction battery: Mainly used in electric vehicles and small electric tricycles.

　　Such as: 6-DZM-10AH

　　3. Traction battery: used for power supply of electric cars, battery cars, battery plug-in cars, industrial and mining electric cars, etc.

　　Such as: 6-DA-150D---for electric vehicles.

　　The start-up battery is mainly a high-current instantaneous discharge, and the traction battery needs a stable constant current discharge. Generally, the starting current of a car is 3 times the current of the nominal capacity of the battery, and the electric car is generally between 5A-20A.

　　two. According to the performance of lead-acid batteries, it can be divided into:

　　1. Dry-charged battery: a battery with a dry and fully charged state.

　　Such as: 6-QA-100 battery. (Mainly used in cars)

　　2. Non-dry charged battery: a battery with the plate in a dry half-charged state.

　　Such as: 6-Q-135J battery. (Mainly used in automobiles, ships, power locomotives, etc.)

　　3. Maintenance-free storage battery: using low antimony alloy, only a small amount of maintenance is required during use, that is, the refill period is extended.

　　Such as: 55B24LMF battery. (Mainly used in small cars)

　　4. Maintenance-free battery: A battery that does not require maintenance and pure water during use. (Rich liquid)

　　Such as: 6-QW-54 battery (mainly used in small cars)

　　5. Valve-regulated sealed maintenance-free storage battery: Adopting the design of adsorption type ultra-fine glass fiber separator and negative plate with excessive active material.

　　Such as: MSE-500 battery. (Mainly used in electric bicycles, UpS backup power supply)

　　Under normal circumstances, we divide the battery into three types to repair, flooded, flooded maintenance-free, maintenance-free, flooded and flooded maintenance-free repair methods are the same. Flooded:

　　The shell is generally white, with a liquid injection port on the top of the shell, and an electrolyte height scale line on the side. It is mainly used in large cars and motorcycles. Flooded type maintenance-free: the shell is generally opaque, there is no liquid injection port, there is no electrolyte height indicator, shaking the battery can feel the water inside. Maintenance-free: no injection port, no electrolyte height indication, no water inside the shaking battery, mainly used in electric bicycles and backup power supplies
