The number of amps you should use to charge a 12V lead acid battery depends on its capacity. As a general rule, you should use a charging current of 10% of the battery’s capacity. For example, a 100Ah battery should be charged with a current of 10A.
As a general rule, you should use a charging current of 10% of the battery’s capacity. For example, a 100Ah battery should be charged with a current of 10A. In conclusion, the recommended charging current for a new lead acid battery depends on the battery capacity and the charging method used.
Unlike LiPo batteries with have a maximum current rating, the lead acid battery only stated the "initial current", which is used for charging. The label stated not to short the battery. Hence, may I know what/how to find out the safe current to draw? How will the battery fail if I draw too much current (explode/lifespan decreased/?)? Thanks
IEI charging is a very popular charging method for lead acid batteries. What you want to avoid is heat and gassing. I found through experimenting that a battery will take in almost as much current as it can put out, so if you have a low internal resistance battery high current is appropriate.
However, like most things in life, there are limits. And some battery manufacturers do specify a quite low maximum charge current (amps). This is usually specified as, for example, I=0.2C 20, which translates to charge current (I) should be limited to 20% of the batteries rated capacity (C) measured when discharging it over 20 hours ( 20 ).
Customers often ask us about the ideal charging current for recharging our AGM sealed lead acid batteries. We have the answer: 25% of the battery capacity. The battery capacity is indicated by Ah (Ampere Hour). For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah.

For optimal charging, use a charger designed specifically for sealed lead-acid batteries. The charger should have a voltage output between 2.30 volts per cell (float) and 2.45 volts per cell (fast). Always monitor the battery''s temperature, as high temperatures can cause damage. ... What are the recommended charging current limits for sealed ...
Live ChatAs a reminder, these are the 3 stages or modes applicable for normal charging of lead acid batteries: Bulk mode: Charging current is limited up to a "safe" value, while the battery voltage increases. It is a constant current (CC) mode. When current starts to reduce, the battery is charged at aprox. 80% of rated capacity.
Live ChatThe max safe current is the CCA rating for 30 seconds max and 30 second intervals. Exceeding this may warp the plates of batteries, boil the electrolyte and with sparks create a safety hazard.
