Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
This concentration of sulfuric acid is characteristic of a nearly fully charged battery. For partially or fully discharged battery, the sulfuric acid concentration and sulfuric acid–specific gravity are lower. Lead–acid batteries are characterized by a direct dependence of battery open-circuit voltage on the state of charge.
We’ve put together a list of all the dos and don’ts to bear in mind when charging and using lead-acid batteries. Apply a saturated charge to prevent sulfation taking place. With this type of battery, you can keep the battery on charge as long as you have the correct float voltage.
The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V. This stage of charging is also called “absorption,” “taper charging,” or trickle charging.
If at all possible, operate at moderate temperature and avoid deep discharges; charge as often as you can (See BU-403: Charging Lead Acid) The primary reason for the relatively short cycle life of a lead acid battery is depletion of the active material.
For many years, several studies were made to improve conventional charging techniques of lead acid batteries. On the other hand, other studies were held to invent some new tactics that have better features. This paper is a review on different charging techniques of lead acid batteries.
