6 FAQs about Base station lead-acid battery gets hot

How does temperature affect lead-acid battery performance?

High temperatures can dramatically affect lead-acid battery performance in several ways: Lead-acid batteries naturally lose charge over time, but high temperatures accelerate this process. At 25°C (77°F), a typical self-discharge rate is around 3-5% per month. However, at 35°C (95°F), the rate can double, leading to rapid depletion.

What temperature should a lead acid battery be charged?

Lead acid batteries operate best at 20°C–25°C. For every 10°C above 25°C, lifespan decreases by 50%. Below 0°C, capacity drops by 20%–40%. Manufacturers often specify narrower ranges (e.g., 15°C–30°C) for deep-cycle models. Temperature-compensated charging adjusts voltage to counteract these effects.

How do thermal events affect lead-acid batteries?

Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as “thermal runaway.”

Do lead-acid batteries lose charge over time?

Lead-acid batteries naturally lose charge over time, but high temperatures accelerate this process. At 25°C (77°F), a typical self-discharge rate is around 3-5% per month. However, at 35°C (95°F), the rate can double, leading to rapid depletion. Flooded lead-acid batteries rely on water for proper electrolyte balance.

Does acid concentration affect the thermal performance of a lead-acid battery?

It turns out that those values for a realistic acid concentration (30%mass) yield different values that significantly affect the overall thermal performance of the lead-acid battery system.

What happens if a lead-acid battery is not regulated?

Without proper voltage regulation, the battery may suffer from grid corrosion and thermal runaway. Just as excessive heat is detrimental, extremely low temperatures also pose challenges for lead-acid batteries: At 0°C (32°F), a lead-acid battery can lose about 20% of its capacity.
