Compatible Replacement Battery

This Estry S60528 battery replaces the original power cell in compatible Southwestern Bell devices. It delivers a 3.6V output with a 1200mAh rating for direct compatibility. The Ni-MH chemistry provides reliable performance for cordless phone handsets. Built-in protection circuits guard against overcharge, over-discharge, over-voltage and short circuits.

Capacity And Runtime Headroom

The 1200mAh capacity supplies 4.32Wh of energy for extended talk and standby time. It comfortably handles daily cordless phone usage cycles without frequent recharging. Runtime decreases naturally as the cells age over repeated charge cycles. The pack is rated for a one-year service life under normal operating conditions.

Thermals And Power Draw

Normal charging and discharging operations remain within safe thermal limits for Ni-MH chemistry. The protection circuitry prevents excessive heat build-up during over-voltage or short-circuit events. Self-discharge is typical for nickel-metal-hydride cells when the handset sits idle. The 86.0g pack adds minimal weight to the handset during use.
