Replacement for AT&T Cordless Handsets

This Estry E595911 is a direct replacement battery for a wide range of AT&T cordless telephone handsets. It matches the original specifications exactly to restore reliable talk time and standby performance. The pack is sold as a single unit, ready to install in compatible models listed by the manufacturer.

Ni-MH Chemistry Limits

Nickel-metal-hydride cells operate at a nominal 3.6V and 700mAh capacity, delivering 2.52Wh of energy. This chemistry does not suffer from memory effect but self-discharges faster than lithium types, so handsets left off the base for weeks may need a full charge cycle before use. Overcharge, over-discharge, over-voltage and short-circuit protections are built into the pack.

Capacity Decides Fit

The 700mAh rating is the single figure that determines whether this cell meets your handset's original runtime specification. Buyers whose devices shipped with a higher-capacity pack will see shorter talk time, while those needing a lower-capacity original will find this unit physically identical but electrically larger. Confirm the milliampere-hour rating printed on your old battery before ordering.

Questions about this item

Should I choose the 700mAh 3.6V Ni-MH pack or a different capacity for my AT&T handset?

Select the 700mAh 3.6V pack only if your original battery is listed among the compatible models such as E595911, E2901 or part numbers 89-0099-00 and BT27910; other capacities will not fit the charging cradle.

What does the 700mAh 3.6V rating mean for daily talk time on my cordless phone?

The 2.52Wh energy rating (700mAh × 3.6V) typically delivers several hours of talk time and weeks of standby on a DECT handset, matching the original runtime.

Does the Ni-MH chemistry and 3.6V nominal voltage limit charging to the original base station?

Yes, the pack uses standard Ni-MH chemistry at 3.6V, so it charges correctly in the original AT&T base stations designed for part numbers like SB67108 or SYNJ-SB3.
