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.
For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah. So, the charging current should be no more than 11.25 Amps (to prevent thermal runaway and battery expiration). Importantly, if you have other equipment connected to the battery during chargning, it also needs to be powered, so you need to add that to your calculations.
The charging process involves converting electrical energy into chemical energy within the battery cells. The appropriate charging current ensures that the battery receives the necessary energy without causing damage or premature wear. To determine the right charging rate for a new lead acid battery, several factors need to be considered.
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
Charging current plays a significant role in the overall health and performance of a lead acid battery. The charging process involves converting electrical energy into chemical energy within the battery cells. The appropriate charging current ensures that the battery receives the necessary energy without causing damage or premature wear.
Most lead acid batteries have an optimal charging temperature range, usually between 25°C to 30°C (77°F to 86°F). Extreme temperatures, both high and low, can affect the charging efficiency and battery life. It is recommended to charge the battery in a controlled environment within the specified temperature range.

How Many Amps in a 12 Volt Battery? (Calculation & Examples)
Now we can calculate the battery''s ampere capacity (Q) using the formula: Q = E / V Q = 26.4 Wh / 12 V Q = 2.2 Ah. And there you have it! Our 12-volt battery has a capacity of 2.2 ampere-hours (Ah). Remember that a 12-volt battery''s ampere capacity can vary depending on the battery''s wattage and voltage.
amperage
This question is generally answered by saying ''no more than 2 x 2.4 Ah (amp-hours) per cell...or 6 x 2 x 2.4....or no more than 28.40 Amp-Hours per battery, up to approximately 1/4 (0.25) of the battery''s rated Amp-hours...so, a 100-Ah deep cycle battery could be charged up to 100 * 0.25 or 25-Amp-hours charge at 14.58 volts...so if you have a ...
