Methods and steps lead-acid battery electric vehicles to recharge after initial charging of the battery discharge should be carried out immediately after the supplementary charge to ensure that the electrical performance of the battery from damage and extend the life of 1. Flow Method: The current charge sufficient to 0.05C10A so far. 2. Low-voltage constant voltage charging method: first with 0.1C10A the current charging to the battery terminal voltage of 2.35V, time is about 10h, and then to 2.35 ± 0.02V constant voltage charging, adequate so far. Normal charge's charge about the actual release capacity of 1.3-1.5 times (to take maximum from the second discharge). 3. Normal charging process, the electrolyte temperature must not exceed 45 ℃. 4. When charging is completed, the electrolyte density adjusted to 1.24 ± 0.01 (20 ℃), and the level to the maximum level line.

The main types of lead-acid batteries and automotive batteries purposes: for automotive starters, intelligent battery modules, lighting, ignition, etc., which require large current discharge, low temperature performance characteristics. Fixed Battery: Widely used in electric power, telecommunications, power plants, nuclear power plants, hospitals, halls, etc., as a backup power source. Railway Passenger Car Battery: mainly used for train lighting, ventilation and other standby power. Traction batteries: mainly used battery car, truck, mine locomotive power, require deep charge-discharge performance, so use tubular positive plate of the battery. Locomotive Battery: mainly used for diesel locomotive starting, lighting, smart battery, requiring large current discharge performance, so use paste type electrode plate. Motorcycle batteries: mainly used for motorcycle starter, ignition, intelligent battery wholesale, lighting, etc., requires a large current discharge performance is good. Bicycle Battery: mainly used in electric bicycles, electric tricycles, electric scooters and other power supply.
