To prevent damage while discharging a lead acid battery, it is essential to adhere to recommended discharge levels, monitor the battery’s temperature, maintain proper connections, and ensure consistent maintenance. Recommended discharge levels: Lead acid batteries should not be discharged below 50% of their total capacity.
By understanding and implementing these practices, users can effectively prevent damage while discharging a lead acid battery and ensure its reliable performance. Discharging a lead acid battery too deeply can reduce its lifespan. For best results, do not go below 50% depth of discharge (DOD).
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
Sealed lead acid batteries need to be kept above 70% State of Charge (SoC). If you are storing your batteries at the ideal temperature and humidity levels then a general rule of thumb would be to recharge the batteries every six months. However if you are not sure then you can check the voltage as follows:
Specific actions and conditions can contribute to the premature discharge of a lead acid battery. For example, frequent deep discharges, prolonged storage in a discharged state, or operation in extreme temperatures can exacerbate the sulfation process. Regular maintenance and following guidelines for discharge levels are vital.
