RKH12-535
HIGH RATEDCritical Power Without Compromise
Rekoser High Rated battery. RKH Series provides superior performance in both high cycling and floating applications. Built with high quality AGM separator, it extend cycle life and prevent micro short circuit. PbCaSn alloy is used for plate grids for less gassing, less self-discharging. It has an unique vent valve design: reduce water losing and prevent air/spark going inside. It is ideal for UPS, Laboratories, Emergency Power Supply, Data & Network Operation Centers, etc.
