Do lead acid batteries go bad?

The liquid-filled lead acid batteries used in automobiles and a range of other products have many great qualities, but are also known to “go bad” with little warning. Fortunately, you can easily do a basic health checkup on any type of lead acid battery by hooking it up to a simple-to-use digital voltmeter.

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 test a lead acid battery with a hydrometer?

Checking an open-cell lead acid battery—that is, a lead acid battery with caps that can be opened to access the liquid inside—with a battery hydrometer is most accurate when the battery is fully charged. Closed-cell lead acid batteries without the access caps cannot be tested this way.

How do you know if a lead-acid battery is bad?

If the voltage reading is lower than the manufacturer’s specifications, the battery may be weak and need to be replaced. If the voltage reading is within the manufacturer’s specifications, the battery is likely in good condition. To get a more accurate reading of a lead-acid battery’s health, you can use a hydrometer.

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 be charged before testing?

Charge the battery fully at least 8 hours before testing it. Lead acid batteries recharge in various manners based on their function and manner of installation. For a lead acid vehicle battery, drive the vehicle around for at least 20 minutes. For a lead acid battery connected to solar panels, let the battery charge fully on a sunny day.
