1. When battery indicator pro shows that one third of the power is left, charge the battery.

2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles, because it is easy to burn when the charger is airtight.

3, try not to use fast charge, if not necessary, don't more than twice a month.

4, the charger in a fixed place, don't bump, even if you carry it, you should fully consider the failure caused by bump.

5. Use a standard charger to charge.

6. The ideal charging time is when the battery consumes 60%~80%.

7. Be diligent.

Precautions:

1. The lead-acid battery has no regulations on the initial charging time and charging amount, and can be charged and discharged at any time, without causing the memory of the plate.

2. It should be noted that over-discharge and over-charge are absolutely forbidden, which will lead to the thinning of the metal layer of the grid and easy to break the grid. Excessive discharge will lead to sulfidation of electrode plate, failure of active sponge structure and shortened service life of electrode plate. Lead-acid batteries should pay attention to the specific gravity and liquid level height of electrolyte, and should not be short of liquid.

When the lead-acid battery is used in the car, it is always charging and discharging. The meter of the battery on the old Jiefang truck is an ammeter with a pointer, and you can see whether it is charging or discharging at any time.

Especially when the headlights are fully turned on and the high beam is turned on, the power supply of the generator is insufficient. When the generator slows down, the speed of the generator is low, that is, the electricity in some batteries is called, so it will automatically switch between charging and discharging dozens of times every night, which has no effect and does not need to be fully charged like a nickel-hydrogen battery.
