This means that the current should be no more than half the rated capacity of the battery. So for example, if you are using a 54 Ah battery, the charge current should be no more than 14A. Using too high a current can cause damage to the cells and reduce the life of the battery
Contrary to what some comments/answers may suggest, the charger needs to be told the maximum current to deliver. They normally don't/can't 'sense' it. The important thing is to use the correct battery charger circuitry based on the chemistry of the battery.
Several factors, including the battery capacity and charging rate, affect the battery charging current. The larger the battery capacity, the higher the charge current typically is. Likewise, the higher the charging ratio, the higher the charging current and the shorter the charging time.
When a battery is fully charged, the charging current drops to 0.1C. The circuit switches to constant voltage charging mode once the voltage achieves its maximum, charge cut-off voltage. The charging current of the battery steadily lowers down, and the charging rate slows down when the voltage is sustained at charge cut-off voltage.
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
If the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C. Higher (15C) charge and discharge current, suitable for use as a power battery. The current used to charge a battery could have an effect on its lifetime.
