Correct charging method of lead-acid battery

1. The lead-acid battery needs to be charged with the original charger: the charger must match the configured battery. To get into the habit of charging on the same day, you need to fully charge it after use every day. If the power is used up, the battery life will be shortened due to deep discharge. In addition, the charger will generate a certain amount of heat during battery charging, so it is recommended to charge in an open and ventilated place. It is forbidden to cover the charger with foreign objects when charging, otherwise it will easily damage the charger and battery, and even cause a fire accident.

2. It usually takes about 45-65 hours to charge the battery for the first time: firstly, charge the battery with the initial current until the electrolyte releases bubbles, so that the cell voltage of the battery rises to 2.3-2.4V, and then continue charging with the initial current of 1/2 until the electrolyte bubbles violently and the voltage is stable for 3 hours.

Matters needing attention in charging lead-acid battery

It is not suitable to charge the battery after riding: the life of the battery is determined by the number of charging and discharging cycles, and the number of charging and discharging cycles should be correctly grasped. The more charge and discharge cycles, the faster the life decay. The cycle life of lead-acid batteries is generally changed once every two years, so electric vehicles should not be recharged as long as they ride, and should be recharged when the batteries are discharged.

No driving without electricity: Some users will charge the electric car until it can't ride, which will seriously damage the battery performance. Repeated deep discharge will greatly shorten the battery life. If there is not enough power on the way, it is best to pedal in advance to avoid deep discharge. It must be fully charged at one time, and it will be used if it is not fully charged, which will reduce the service life of the battery. Usually try to avoid charging at the fast charging station.
