In July 2009 we presented an improved version of the Battery Zapper & Desulphator. Here we present the companion Battery Condition Checker. It gives more stable readings for all three main battery voltages (6V, 12V & 24V) than our earlier model, as well as giving a choice of test current pulse levels to suit batteries of different capacities. As a result, itÂ’s now also suitable for testing sealed lead acid (SLA) batteries.
