The lead-acid battery mainly uses two types of charging methods namely the constant voltage charging and constant current charging. It is the most common method of charging the lead acid battery. It reduces the charging time and increases the capacity up to 20%. But this method reduces the efficiency by approximately 10%.
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.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
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.
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.
Overcharging can cause the battery to release harmful gases and may lead to electrolyte loss, reducing its capacity and lifespan. It is essential to charge the battery within the recommended current limits. The charging current for a new lead-acid battery is a crucial factor in ensuring its optimal performance and longevity.
