Compatible phones

The Estry SL4 is a nickel-metal-hydride replacement battery built for Phone Mate SL4 and SL5 cordless handsets. It delivers 3.6V and 600mAh for 2.16Wh of capacity. The cell includes overcharge, over-discharge, over-voltage and short-circuit protection. It measures 42.64 x 30.0 x 14.45mm and weighs 63.3g.

Not for other handsets

Buyers with different Phone Mate models or other brands should look elsewhere because the connector and dimensions only match the SL4 and SL5. The pack is not designed for high-drain devices or as a generic AA substitute. Users needing longer talk time will need a higher-capacity pack if one exists for their model.

3.6V 600mAh Ni-MH chemistry

The single specification that decides fit is the 3.6V 600mAh nickel-metal-hydride chemistry in the exact 42.64 x 30.0 x 14.45mm form factor. Matching voltage, capacity and physical size ensures the handset charges correctly and the battery door closes.
