Pro-12 Charge/Maintenance System (110 Volt) - Keep Up To 12 New Batteries Factory Fresh All The Time. If you sell, stock or service lead-acid batteries, this Pulsetech product keeps new batteries sulphur deposit free and maintains maximum charge safely.

Excellent product. It should be mandatory for all entities that have batteries on the shelf to have one of these. I am not sure that the pulsing mechanism works as stated. But what I am sure is that the batteries are kept 'topped up' all the time.

RediPulse PRO-12-RP Battery Maintenance System is not designed to be used on batteries that sit below 11.5 volts or batteries that are heavily sulfated. Ideally, batteries that are excessively discharged or sulfated should be recharged with a standard charger prior to being placed on this low amperage battery maintenance system. This unit was designed for battery shops to keep new and lightly used batteries factory fresh. This unit may not offer sufficient amperage to serve as a maintainer when used on older batteries that have a higher natural discharge rate.
