6 FAQs about [Lead-acid battery deep discharge 6]

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?

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).

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%. Figure: Relationship between battery capacity, depth of discharge and cycle life for a shallow-cycle battery. In addition to the DOD, the charging regime also plays an important part in determining battery lifetime.

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.

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.

How often should a lead acid battery be charged?

For deep cycle lead acid batteries, charging after every discharge is important to extend their lifespan. Avoid letting the battery drop below 20% charge frequently, as this can also damage the battery. In summary, frequent charging at moderate discharge levels maintains the battery’s performance and longevity.
