RKG2-400 (2V 400Ah | 420Ah )

2V 400Ah | 420Ah Gel Deep Cycle Batteries

2V 400Ah | 420Ah Rekoser Rekoser Gel battery. RKG Series provides superior performance in both high cycling and floating applications. By combining the newly developed Nano Gel electrolyte with high density paste, the RKG series offers high recharge efficiency at very low charge current. The acid stratification is highly reduced by adding Nano Gel. It is suitable for off-grid photovoltaic, wind or hydro power application.
