What is the difference between the Pulse Charger, RediPulse Pro-10 and the Pulse Recovery System?
As stated in a previous answer, the 20-Amp Pulse Charger/World Version is designed to charge single 12-volt batteries. The RediPulse Pro-10 and the Pulse Recovery System (PRS) are designed to desulfate and condition multiple batteries. The Pro-10 works on 12-volt batteries and the PRS works on both 6- and 12-volt batteries.
