If the software reads between 1. 1 plus 1. 2 volts, a cell is good. If perhaps it reads below 1. 1 volts, upgrade the cell. Put on mark relating to the cell using a marker pen so that you know which cells have replacing. 5. Replace doing this for each cell while in the pack using the voltmeter mainly because before.
