What happens when a lead acid battery is discharged?

At discharge, the lead is converted into lead sulphate (a white powder in the open air) while the sulphuric acid content decreases in the acid solution (i.e., the density drops to 1.0 = only water). How should a lead acid battery be charged? Different recommendations apply to the different types of lead acid batteries.

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.

Can You overcharge a lead acid battery?

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.

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.

What causes a lead acid battery to self-discharge?

Sulfating: This is a buildup of lead sulfate crystals and it occurs when a lead acid battery is left sitting without a full charge. Even if you are giving your battery a small charge such as putting it in the car and letting it idle, this is still not enough to combat the self-discharge that can take place.

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.
