The effect of the output current of the charger on the battery丨MSH

1. There is a difference between fast charging and slow charging. Generally, fast charging has an impact on the battery, but it is not too obvious for lithium batteries; charging current is usually one-tenth or half of the capacity of lithium batteries. Yes, for example, a 1000mAh battery can be charged at 100-500MA, but if the current is too large, the charger will heat up, which is likely to cause a safety accident.

2. For batteries of different capacities, the charging current of the charger is required, because the charging current that is too small cannot be charged. The so-called trickle charging can supplement the battery capacity, which means that when the battery is about to be fully charged, the trickle charging current is used to make up for the remaining battery capacity of the battery and the battery self-discharge afterward. , Using a small current, it is basically impossible to charge, not to mention the loss of the battery, and the extended life.

3. At present, most of the chargers on the market belong to the chargers that use the complex voltage method, that is, fast charging, and the charging current is changed. 1.5A means that the maximum current is 1.5A, but it will gradually drop to 1A and below with time and battery voltage changes, and 1A means that the current starts to drop from 1A, and its downward trend is uncertain.
