When it comes to maintaining a sealed lead-acid battery, one of the most important things to look out for is signs of battery failure. Here are some common signs that your battery may be failing: Reduced Capacity : If you notice that your battery isn''t holding a charge as well as it used to, it may be a sign that it''s starting to fail.
Ironically one of the most common reasons for battery failure is not an actual failure of the battery itself, it is people thinking the battery is dead. Some manufacturers and retailers report that up to 50% of batteries returned under warranty are actually fit and healthy.
The 36 or 48 V valve-regulated lead-acid (VRLA) battery packs have been widely applied to the power sources of electric bicycles or light electric scooters in China. The failure modes of the 12 V/10 Ah VRLA batteries have been studied by the cycle life test at C 2 discharge rate and 100% depth of discharge (DOD).

Abstract. Lead-acid batteries have the advantages of wide temperature adaptability, large discharge power, and high safety factor. It is still widely used in electrochemical energy storage systems. In order to ensure the application of batteries under extreme working conditions, it is necessary to explore the degradation mechanism. In this …
When the temperatures get lower, the reactions slow down and the power given by the battery is lower. However, the battery life is prolonged. The ideal operating temperature of the battery is 25 0 C. Sustained temperatures above these for days on end or weeks will lead to damage to the battery that will shorten the battery life. ...
Failure modes of valve-regulated lead/acid batteries are discussed and methods are suggested to overcome the problems. Many of the failures are associated …
However, in practice a number of irreversible processes result in the eventual failure of the lead-acid battery. As these processes or ''failure modes'' limit the lifespan of the battery, there have been numerous investigations into factors influencing these failure modes with the prime objective being to circumvent their occurrence [8,10–13].
