How to recover a lithium battery after a power outage?
1. Low voltage charging method
In this case, you can use a relatively small charger to charge the battery. . For example, if the battery is 60V-20Ah, you can use a 48V-20Ah charger to charge it. After two hours of charging, the voltage will increase significantly. At this point, switch to a 60V-20AH charger for charging.
2. Special charger
More experienced repairers usually prepare chargers with repair functions. This type of charger is mainly used to charge the battery. It can charge the battery regardless of the battery voltage, and the power failure repair rate is generally relatively high.
3. Charging a single battery
In order to maximize the probability of battery activation, each battery in the entire battery can be charged witha 12V charger. However, as the battery often stays too long, you should pay attention to the charging time being longer than usual, in order to achieve satisfactory results.
4. Simple batteries connected in parallel
An ordinary battery with saturated power can be directly connected to a battery that lacks power according to the method of connecting the positive electrode to the positive electrode and the negative electrode to the negative electrode. All the defective batteries in the group may work in the same way one after the other.
5. Connect the whole battery in parallel
According to the same principle, connect the two sets of batteries in series to a battery with the same voltage and saturated power, then Connect the total of the positive and negative poles of the two sets respectively of batteries. Connect and operate using the “battery charging” method. A thing of nNote is that the rated capacity of the selected normal battery is better than the rated capacity of the exhausted battery.
