Compatible replacement for AT&T 17 50

This Estry Ni-MH battery replaces the original pack in AT&T models 17 and 50. It delivers 2.4 V and 1500 mAh capacity in the same physical dimensions of 50.8 x 28.05 x 14.44 mm and weighs 66.6 g. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety and quality.

Sustained discharge with protection circuits

Built-in overcharge, over-discharge, over-voltage and short-circuit protection maintains stable output during long calls or standby periods. The 3.6 Wh energy rating supports extended talk time without sudden voltage drops that can reset the handset. One-year battery-pack warranty backs the durability claim.

Voltage and capacity match

The single specification that decides fit is the 2.4 V / 1500 mAh rating matching the original pack. Buyers whose handset requires a different voltage or a higher capacity will need another part. Confirm the model number 17 or 50 before ordering.

Questions about this item

How much heat does the 2.4V 1500mAh Ni-MH pack produce during continuous all-day use?

Nickel-metal-hydride chemistry at 2.4V and 1500mAh generates only mild warmth under normal phone load; the 3.6Wh energy rating means heat stays low during extended talk or standby time.

What must I already own for this Estry 1500mAh 2.4V pack to work?

You need an AT&T cordless handset model 17 or 50 that accepts a 50.8 x 28.05 x 14.44 mm, 66.6 g battery with the original connector.

Will this 2.4V 1500mAh replacement work alongside the original charger base I kept from my AT&T 17 or 50?

Yes — the pack matches the original 2.4V voltage and 1500mAh capacity, so the existing charger base will charge it normally without modification.
