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.
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.
Voltage Level: The voltage level directly affects the state of charge in a lead-acid battery. Each lead-acid cell typically has a nominal voltage of 2 volts. For a 12-volt battery composed of six cells, a safe discharge level is usually around 12.0 volts, which corresponds to about 50% state of charge.
Lead acid batteries need a specific 3-stage charge process 6 in order to preserve their condition. In practice, if you don't discharge a battery beyond 50%, it takes less time to recharge the battery 7. It can be a good idea to hookup unused batteries permanently to a 'tricklecharger'.
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).
Normally, a fully charged lead acid battery shows about 12.6 volts. According to the Battery University, a voltage reading of 10.5 volts or lower typically signals that the battery is nearing a critical discharge level. Prolonged exposure to this state can lead to irreversible damage.
