Replacement battery for six cordless models

The Estry SC-625 is a 6.0 V nickel-metal-hydride pack rated at 4200 mAh and 25.2 Wh. It matches the original dimensions of 89.3 x 46.5 x 37.8 mm and weighs 405.0 g. The pack fits SC-625, ST-634, CC-664, SC-634, CC-684 and CC-695 devices. Buyers who need a different voltage or chemistry cannot use this pack.

Drop-in fit with built-in protection

No soldering or adapter is required; the pack slides into the existing battery compartment of each listed model. Integrated circuitry guards against over-charge, over-discharge, over-voltage and short-circuit events. The RoHS, CE, ISO 9001, UN 38.3 and MSDS certifications confirm compliance with transport and substance restrictions. Builders who require a smart-bus interface or hot-swap capability will not find those features here.

Steady output during long runs

The nickel-metal-hydride chemistry delivers a stable 6.0 V through extended discharge cycles without the voltage sag seen in short-burst tests. Protection circuits prevent deep-discharge damage when the pack is left in storage between jobs. The 4200 mAh capacity supports multi-hour operation on a single charge. Users who demand rapid-recharge cycles under fifteen minutes will need a different chemistry.
