How much is the charging current for the car battery? What is the appropriate charging current for the car battery?

I believe that many friends know which charging voltage (12V/24V) to choose, but when asked how much the charging current of the car battery is adjusted, many car friends are "asking three questions". So, in order to answer your doubts, today we will talk about how suitable the charging current of the car battery is.

The battery charging current is related to the battery capacity, and is generally one-tenth of the battery capacity (error ±0.5). For example, for a battery with a specification of 12V20aH, the normal charging current is 1.5A-2.5A. But never adjust to excessive current output, the consequences are unimaginable (damage the car battery). Of course, the current chargers on the market are very intelligent and can automatically adjust the output current according to the battery condition, thereby minimizing the damage to the battery.

It is worth mentioning that normally, the battery can be fully charged after 4-5 hours of charging(12V20aH), It is best not to overcharge the battery frequently. Although the current generated by the charger is not very large, because the electrolyte is in a boiling state for a long time, not only the fine particles on the surface of the active material are easy to fall off, but in serious cases, the grid frame will be oxidized, resulting in loosening of the active material and the grid frame. Stripping, so everyone must be full of energy when charging.
