Direct replacement for SANYO cordless phones

The Estry CLT9571 is a 3.6V 1200mAh nickel-metal hydride pack built to match the original specifications for SANYO handsets. It fits models such as CLT9571, CLT9812, CASA9000, CLT9581 and CLT9905 among others. The cell delivers 4.32Wh of energy in a 50.43 x 42.54 x 14.4mm form factor weighing 90.3g.

Certified safety and simple drop-in fit

The battery carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications confirming compliance with quality and environmental standards. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits. The pack uses the same connector layout as the original so installation requires no soldering or adapter cables.

Ni-MH chemistry limits runtime and shelf life

Nickel-metal hydride cells self-discharge faster than lithium types so capacity drops noticeably after weeks of storage. Memory effect can reduce usable capacity if the pack is repeatedly recharged before full discharge. The 1200mAh rating suits typical cordless phone duty cycles but will not support high-drain devices.
