Direct replacement battery

This Estry 14.4V 2800mAh Ni-MH pack matches the original GD-RA-500 specifications for IR RA robotic cleaners. It fits models including RA 500 530 550 570 595 600 630 660 700 790 800 960 and Xlife S variants. Built-in protection guards against overcharge over-discharge over-voltage and short circuits.

Steady runtime on long jobs

The 40.32Wh capacity delivers consistent power through extended cleaning cycles without the voltage sag seen in aged cells. ISO9001 RoHS CE UN38.3 and MSDS certification confirm stable chemistry under continuous load. The 560.5g pack maintains output across the full discharge curve.

Upgrade from depleted OEM packs

Replaces worn original batteries that no longer hold a full charge or trigger low-voltage shutdowns mid-cycle. The jump is worth it when run time has dropped below useful levels or the cleaner fails to return to its dock. Not for users needing higher capacity than 2800mAh or a different voltage platform.
