How to discharge lead-acid batteries at low temperatures
The problems associated with cold temperature operation for lead-acid batteries can be listed as follows: 1. Increase of the on-charge battery voltage. The colder the battery on charge, the higher the internal resistance. This raises the on-charge voltage, which can fool automatic and 'intelligent' chargers into. Fig 1shows the results of an investigation by the Department of Physics at the University of Garhwal in India. In this, the researchers showed the effect of temperature on four key properties of lead-acid batteries. These were: charging voltage and current,. Because of this, it is important that temperature correction factors are used to adjust battery chargers to take into account temperature. A primary consideration for a battery operation is the charging method. It is vital to understand the dependence of correct charging on accurately knowing and interpreting a lead-acid. Added to the charging voltage variation is the inherent lower capacity of a battery with temperature reduction. Fig 4shows how a lead-acid battery's run time will be reduced as its temperature.
