Since that is no longer an issue (and never was an issue with lead acid batteries) there is not a need to fully discharge. By discharging a lead acid battery to below the manufacturer’s stated end of life discharge voltage you are allowing the polarity of some of the weaker cells to become reversed.
All batteries experience some amount of self-discharge, yes. But, the rate of discharge for lead acid batteries depends on a few key factors. Temperature: The warmer the environment while a battery is in storage, the faster the rate of self-discharge.
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.
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.
A lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month. This rate increases as temperatures rise and as the risk of sulfation goes up. Sulfating: This is a buildup of lead sulfate crystals and it occurs when a lead acid battery is left sitting without a full charge.
Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
Charging a lead acid battery. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted. It''s not possible to just dump a lot of …
For example, a 1C rate will fully charge or discharge a battery in 1 hour. At a discharge rate of 0.5C, a battery will be fully discharged in 2 hours. The use of high C-rates …

The self-discharge rate of a lead-acid battery is related to the ambient temperature of the battery, the higher the room temperature higher will be the self-discharge …
Discharging a lead acid battery too deeply can reduce its lifespan. For best results, do not go below 50% depth of discharge (DOD). Aim to limit discharges to

Table 2: Effects of charge voltage on a small lead acid battery. Cylindrical lead acid cells have higher voltage settings than VRLA and starter batteries. ... For a 40 hours discharge at 1.3A you only got about 52 AH, that …
Do lead acid batteries discharge when not in use? All batteries experience some amount of self-discharge, yes. But, the rate of discharge for lead acid batteries depends on a few key factors. …
Peukert''s Law describes the non-linear relationship between the discharge rate and the actual capacity delivered by a lead-acid battery. The battery''s effective capacity decreases with …
Avoiding the full discharge of a lead acid battery is crucial for maintaining its health and longevity. Fully discharging these batteries can lead to permanent damage, …
I''ve read that lead acid battery not should be discharged too quickly, as this might result in overheating the battery (and cause damage to it). How do I figure out what a …
The discharge rate of AGM batteries is measured in C-ratings. A 1C rate means the battery discharges its full capacity in one hour. Higher C-ratings allow faster discharge. …
Constant current discharge curves for a 550 Ah lead acid battery at different discharge rates, with a limiting voltage of 1.85V per cell (Mack, 1979). Longer discharge times give higher battery capacities.
