Unlike some batteries, lead-acid batteries do not have a "memory effect." However, deep discharges negatively affect voltage levels and overall battery performance. To optimize battery life, it''s best to keep the battery charged. Moreover, consistently allowing full discharge can lead to battery failure.

What Is Deep Discharge and How Does It Affect Batteries?

Depth of Discharge (DoD) measures the energy a battery has used. For example, if you have a fully charged battery rated at 100 Ah and used 40 Ah, your DoD is 40%. The state of Charge (SoC) indicates how much energy remains available in the battery at any given time. Using the previous example, if you have used 40 Ah from your fully charged 100

6 FAQs about [Does lead-acid battery have a discharge effect ]

Do lead acid batteries need to be fully discharged?

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.

How long should a lead acid battery stay discharged?

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.

Do lead acid batteries have a memory effect?

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 any type of memory effect.

When should a lead acid battery be charged?

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.

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.

What happens when a lead-acid battery is discharged?

Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
