The institute of electrical and electronics engineers ieee has published recommended standards for battery maintenance testing and replacement.
Vented lead acid battery maintenance.
And replacement of vented lead acid batteries for stationary applications ø ieee 1188 recommended practice for maintenance testing.
All of the activities of verification inspection and testing should be documented and retained as evidence for audits.
An appropriate ventilation takes care that the gases are quickly removed and do not accumulate to a critical level.
With shipping plugs removed vented lead acid batteries can give off minor amounts of hydrogen and oxygen due to normal evaporation of water depending upon the amount of ambient heat and air humidity.
Lead acid battery maintenance and testing.
Sealed battery vrla maintenance services ats provides the most up to date testing techniques for valve regulated lead acid battery systems.
This document provides recommended maintenance test schedules and testing procedures that can be used to optimize the life and performance of permanently installed vented lead acid storage batteries used in standby power applications service.
Standard details maintenance test schedules and testing procedures that can be used to optimize the life and performance of permanently installed vented lead acid storage batteries used for standby service are provided.
Vented lead acid batteries would normally be stored with shipping protecting plugs installed in which case they release no gas.
Maintenance of lead acid battery if the cells are over charged the physical property of lead sulfate gradually changes and it may become obdurate from which it becomes difficult to convert by charging process.
It also provides guidance to determine when batteries should be replaced.
This is crucial in order to eliminate the risk of an explosion.
In vented non maintenance free lead acid battery systems gases evolving from the water decomposition escape though the provided venting system.
The required maintenance activities of the time based program are divided according to the type of battery.
Following ieee 1188 ats performs voltage ac ripple and internal ohmic measurements and then trends them over the life of the maintenance program.
For vented lead acid vla or flooded batteries for stationary applications.

The lead acid battery was invented in 1859 by french physicist gaston planté and is the earliest type of rechargeable battery despite having a very low energy to weight ratio and a low energy to volume ratio its ability to supply high surge currents means that the cells have a relatively large power to weight ratio these features along with their low cost make them attractive for use in.
