6 Frequently Asked Questions about “Lead-acid batteries lose power rapidly in summer”

Do flooded lead acid batteries lose water?

Both conventional flooded lead acid batteries and Absorbed Glass Mat (AGM) batteries suffer water loss in extreme heat—and water is essential to the electrochemical process within the battery. Lead acid batteries function using an electrochemical process in which lead plates react with an electrolyte.

Why do lead-acid batteries fail?

Battery failure rates, as defined by a loss of capacity and the corrosion of the positive plates, increase with the number of discharge cycles and the depth of discharge. Lead-acid batteries having lead calcium grid structures are particularly susceptible to aging due to repeated cycling.

How long does a lead-acid battery last?

general rule of thumb for a vented lead-acid battery is that the battery life is halved for every 15°F (8.3°C) above 77°F (25°C). Thus, a battery rated for 5 years of operation under ideal conditions at 77°F (25°C) might only last 2.5 years at 95°F (35°C).

What happens if a battery is reduced to 80%?

A reduction to 80% of the rated capacity is usually defined as the end of life for a lead-acid battery. Below 80%, the rate of battery deterioration accelerates, and it is more prone to sudden failure resulting from a mechanical shock (such as a seismic event) or a high discharge rate.

Do lead-acid batteries self-discharge?

All lead-acid batteries will naturally self-discharge, which can result in a loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery's electrolyte and the chemistry of the plates.

Does summer heat affect battery performance?

Most people know that cold weather affects battery performance. But what about the effect of summer heat on your heavy-duty battery? The fact is, that extreme heat is also detrimental to battery life.
