Five ways to extend the life of your lead acid battery. Part I
Most of us monitor the state-of-charge of a battery by the rough and ready method of ''observing battery voltage''. In the fast-charge installation imagined above, for example, voltages climb so quickly that it gives us the illusion that our battery is fully charged, and that we can therefore terminate the charge cycle believing that the job to …
Lead–acid battery fundamentals
Lead–acid batteries in applications with restricted charging time or in PSoC operation are rarely fully charged due to their limited charge-acceptance. This situation …

Lead-acid battery
OverviewCyclesHistoryElectrochemistryMeasuring the charge levelVoltages for common usageConstructionApplications
Lead-acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate …
Gel Battery Voltage Chart: The Optimal Operating Voltage Range
The battery voltage of a gel battery is typically around 2 volts per cell. This means a 12-volt gel battery will have 6 cells and a voltage of around 12.8 volts when fully charged. Gel batteries also have a rated capacity in amp hours (Ah), which is a measure of the battery''s power capacity.
Why don''t lead acid batteries last forever?
Just because a lead acid battery can no longer power a specific device, does not mean that there is no energy left in the battery. A car battery that won''t start the engine, still has the potential to provide …
