AI Customer ServiceCustomers 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
AI Customer ServiceFor 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.
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
According to Foot Print Hero, a 6V lead acid battery is dead at 5.81V. For a 6V flooded lead acid battery, that figure falls slightly to 5.79V at 0 percent. From the tables on the platform, you can see the capacity of each battery depending on the voltage.
The actual capacity of a lead acid battery, for example, depends on how fast you pull power out. The faster it is withdrawn the less efficient it is. For deep cycle batteries the standard Amp Hour rating is for 20 hours. The 20 hours is so the standard most battery labels don’t incorporate this data.
When using lead-acid batteries it's best to minimize the number of parallel strings to 3 or less to maximize life-span. This is why you see low voltage lead acid batteries; it allows you to pack more energy storage into a single string without going over 12/24/48 volts.
