Flooded Lead Acid
Studer Battery Monitor
Energy is stored in large batteries, similar to a car battery but designed specifically for RAPS, (remote area power systems). They are usually of the lead-acid variety, either 'sealed' or 'flooded cell'. A properly sized, well maintained battery bank is vital to guarantee a reliable, long lasting system.
Batteries require regular maintenance - flooded cells need to be topped up with distilled water from time to time and charged and discharged to a timetable.
