Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
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.
Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let’s suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
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. The most important lesson here is this:
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.
Lead-acid batteries have a capacity that varies depending on discharge rate as well as temperature. Their capacity generally decreases with slow discharges while increasing with high rates. Moreover, lead-acid batteries suffer reduced capacity at extreme temperatures, especially during cold conditions. 3. Self-Discharge Rate
