6 FAQs about [Lead-acid batteries need to be deeply discharged]
How should a lead acid battery be discharged?
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.
How to prevent damage while discharging a lead acid battery?

Should a lead acid battery be fused?
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.
When should a lead acid battery be charged?
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.
What causes premature discharge of a lead acid battery?
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.
How long does a deep-cycle lead acid battery last?
A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%.
