Replacement battery for survey equipment

The Estry GTS-100N is a 7.2V 2700mAh nickel-metal hydride pack built to match the original specifications for a range of total-station and GNSS receivers. It suits field crews who need a direct swap for depleted OEM cells without changing chargers or mounts.

Rugged pack with safety circuitry

The brick measures 135.25 x 68.7 x 26.15mm and weighs 453.4g, fitting the existing battery cavity on listed models. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits, while ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirm compliant construction.

Capacity decides runtime per job

At 2700mAh and 19.44Wh the pack delivers a fixed energy budget; users running long robotic sessions or cold-weather surveys should plan for fewer hours than higher-capacity alternatives. Buyers needing more than 2700mAh per charge must look elsewhere.
