What causes lead-acid battery failure?

Nevertheless, positive grid corrosion is probably still the most frequent, general cause of lead–acid battery failure, especially in prominent applications, such as for instance in automotive (SLI) batteries and in stand-by batteries. Pictures, as shown in Fig. 1 taken during post-mortem inspection, are familiar to every battery technician.

How does a lead acid battery work?

A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.

What is a lead-acid battery?

The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté. It is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density. Despite this, they are able to supply high surge currents.

What happens if a battery terminal is corroded?

Terminal corrosion can eventually lead to an open electrical connection. Changing the connecting terminals to lead, the same material as the battery pole of a starter battery, will solve most corrosion problems. The lead within a battery is mechanically active.

How do you prevent sulfation in a lead acid battery?

Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.

Do valve-regulated lead-acid batteries cause grid corrosion?

In order to avoid the described problem, valve-regulated lead–acid batteries are often maintained at an excessively high float voltage, again with correspondingly adverse effects on grid corrosion, as already mentioned.
