Lead-acid battery life is shortened
Battery Lifetime and Maintenance
Nearly all small common primary batteries are hermetically sealed and require no maintenance, but many secondary batteries, particularly lead acid batteries, require a strict maintenance
Failure modes in lead-acid batteries
That is why the nominal life expectancy of a VRLA battery is about half the life of a VLA battery. It is also why VRLA is frequently referred to as "low maintenance" (i.e., frequent electrolyte replenishment is not required). Dehydration is the natural consequence of old age. Premature dehydration is a failure condition which can lead to other failure modes.
Battery Lifetime and Maintenance
Nearly all small common primary batteries are hermetically sealed and require no maintenance, but many secondary batteries, particularly lead acid batteries, require a strict maintenance schedule. A battery can degrade or can fail catastrophically. Modes are: shorts, degradation of electrode material, freezing, increases in resistance.

Lead–Acid Batteries
At lower temperatures, the battery life is extended and at higher temperatures it is shortened. This has implications on the design of a battery for specific applications, such as photovoltaic systems. If the application is at temperatures other than room temperature, 25 °C, battery sizing must be done to compensate for capacity loss or gain. As the temperature

6 FAQs about [Lead-acid battery life is shortened]
How long does a lead/acid battery last?
The common rule-of-thumb is that a lead/acid battery will last about five years from the date of manufacture. There are, however, several factors that shorten up that lifetime. Between the time that the battery was manufactured and the time the battery was available for sale, you can expect one to three months to have passed.
Why does a lead-acid battery have a low service life?
On the other hand, at very high acid concentrations, service life also decreases, in particular due to higher rates of self-discharge, due to gas evolution, and increased danger of sulfation of the active material. 1. Introduction The lead–acid battery is an old system, and its aging processes have been thoroughly investigated.
What causes a lead-acid battery to short?
Internal shorts represent a more serious issue for lead-acid batteries, often leading to rapid self-discharge and severe performance loss. They occur when there is an unintended electrical connection within the battery, typically between the positive and negative plates.
How does a lead-acid battery shed?
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
What happens when a lead acid battery is recharged?
At the same time the more watery electrolyte at the top half accelerates plate corrosion with similar consequences. When a lead acid battery discharges, the sulfates in the electrolyte attach themselves to the plates. During recharge, the sulfates move back into the acid, but not completely.
How to maintain a lead-acid battery?
As routine maintenance, you should always check the battery electrolyte levels and ensure that the battery cells are always covered. Sealed and valve-regulated lead-acid batteries are designed in such a way that the gases released from the electrolysis of water in the electrolyte, recombine back to form water. 3. Thermal Runaway
