As far as I know, the optimal charge current rate for lead-acid battery is in between 10-30% of its nominal capacity. (2,5Ah -> 0,25-0,75A)The higher the charge current, the higher the degradation of the battery especially over the recommended limit. You may apply higher charging currents sacrificing the cyclical lifespan of the given battery.
The recommended charging current for a new lead acid battery is usually around 10-20% of its ampere-hour (Ah) capacity. For example, if you have a 100Ah battery, the ideal charging current would be between 10-20A. Can I use a higher charging current to charge my new lead acid battery faster?
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.
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.
Charging current for Cycling Use (higher charging voltage) has a limit at 0.3C Amps. Without the limit the battery would pull 2C amps at that charging voltage. In the vehicles, the starting battery, the system load, alternator w/ regulator are all wired in parallel. AFAIK, there is no current limiting between the alternator and the battery.
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.
