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.
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.
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.
The battery may also fail as an open circuit (that is, there may be a gradual increase in the internal series resistance), and any batteries connected in series with this battery will also be affected. Freezing the battery, depending on the type of lead acid battery used, may also cause irreversible failure of the battery.
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.
The following graph shows the evolution of battery function as number of cycles and depth of discharge for a shallow-cycle lead acid battery. A deep-cycle lead acid battery should be able to maintain a cycle life of more than 1,000 even at DOD over 50%.
Pro tip: a good rule of thumb to help avoid the trap of overcharging is to make sure you charge your battery after each discharge of 50% of its total capacity. If the battery will be stored for a …
You can''t fully stop batteries from discharging, but you can do one simple thing across all battery types to lower the discharge rate: keep them cool. Whether you''re trying to keep a lithium-ion or NiMH battery topped off …
There are two main charging techniques for sealed lead-acid batteries: float charging and fast charging. Float charging is a low-level continuous charge that keeps the …
Without them, a battery is just a box of chemicals with no way to transfer energy. Part 2. Types of electrolytes. Electrolytes can be categorized based on their …
Self Discharge. One not-so-nice feature of lead acid batteries is that they discharge all by themselves even if not used. A general rule of thumb is a one percent per day rate of self-discharge. This rate increases at high …
Storing a battery acid outside of a battery is a challenge both in regard to safety and purity. The battery acid is not immediately dangerous to humans (well, keep it away from …
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern …
Lead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate …

Here, we''ll uncover the pros and cons of Lead Acid and AGM batteries. Introduction Lead Acid and AGM batteries are commonly used in cars, industrial settings and …
Lead acid batteries hate being in a discharged state. 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) …
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. …

The lifespan of a lead-acid battery depends on several factors, including the depth of discharge, the number of charge and discharge cycles, and the temperature at which …
Myth: Lead acid batteries can have a memory effect so you should always discharge them completely before recharging. Fact: Lead acid battery design and chemistry does not support …
Special Considerations for Gelled, Sealed Lead Acid Batteries. Gelled or AGM lead acid batteries (which are typically sealed or valve regulated) have several potential advantages: they can be deep cycled while retaining battery life; they …
Among these latter four storage technologies, flooded lead–acid batteries are the most mature, and are followed closely by valve-regulated lead–acid (VRLA) batteries. …
Sealed lead acid batteries need to be kept above 70% State of Charge (SoC). If you are storing your batteries at the ideal temperature and humidity levels then a general rule of thumb would be to recharge the …
Besides, inside the battery there is basically an acid (the density might be lower compared to a bleacher but, still an acid). A lead acid battery can be stored for at least 2 years …
