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.
Hello:
Battery repair is real.
The range of batteries is very wide, including lithium batteries, lead acid batteries, etc. Current repair technology is for lead-acid batteries. That is, maintenance-free batteries and water batteries most commonly used in electric vehicles, as well as maintenance-free batteries and water batteries used to start car ignitions, etc.
Lead acid batteries will experience a decrease in capacity after being used for a period of time. This is due to the battery sulphide phenomenon. For these batteries, the battery repair machine can effectively solve the battery vulcanization and thus can repair most problems such as overcapacityinsufficient battery and reduced battery capacity. So battery repair is true.
Some batteries are also damaged by logistics. For example, if the battery pole is broken, the pole group is short-circuited, etc., it needs to be repaired manually. We can offer free on-site training on this part of the technology.
