A practical understanding of lead acid batteries

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:

How does a lead acid battery accept more current when it is discharged

My belief is it is the self-healing that reduces the ESR to make the battery produce more current with less internal ESR voltage drop. All these variables are pretty dynamic and affect the SOC, expected lifespan etc. and especially reduce MTBF is from deep discharging a normal lead-acid battery for too many hours.

Lead–Acid Batteries

The battery has thin plates or electrodes with larger surface area for high current capability. This type of lead–acid battery is designed to have high power density, but it has low total energy content and is not designed for applications that require energy delivered for long periods of time. It can also not handle deep discharge. The car battery normally operates with

Lithium-ion vs. Lead Acid Batteries | EnergySage

Capacity. A battery''s capacity measures how much energy can be stored (and eventually discharged) by the battery. While capacity numbers vary between battery models and manufacturers, lithium-ion battery technology has been well-proven to have a significantly higher energy density than lead acid batteries.

6 FAQs about [How many times lead-acid battery is discharged with high current]

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.

How deep should a lead acid battery be discharged?

How many Ah can a lead acid battery deliver?

A lead acid battery is rated at 100Ah at C20, this means that this battery can deliver a total current of 100A over 20 hours at a rate of 5A per hour. C20 = 100Ah (5 x 20 = 100). When the same 100Ah battery is discharged completely in two hours, its capacity is greatly reduced. Because of the higher rate of discharge, it may only give C2 = 56Ah.

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.

How a lead-acid battery can be recharged?

Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged. For recharging, positive terminal of DC source is connected to positive terminal of the battery (anode) and negative terminal of DC source is connected to the negative terminal (cathode) of the battery.

How long does a lead acid battery take to charge?

Ideally you can configure the cut-off coltage, such as with the depicted unit. So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. 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.
