Direct replacement battery

The Estry 80-5074-00-00 is a 3.6V 300mAh Ni-MH battery built to match the original specifications for AT&T compatible devices. It fits models 2438 and 5600 and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

1.08Wh capacity for cordless handsets

The 1.08Wh pack delivers reliable talk and standby time for compatible cordless phones. It supports normal daily use but will require more frequent charging under heavy call volumes or if the handset is left off the base for extended periods.

Upgrades worn original packs

This unit replaces depleted factory batteries that no longer hold a charge. The swap is worthwhile when the handset shows reduced talk time or fails to maintain standby, restoring the original runtime without modification.

Questions about this item

Will the 30.0 x 32.0 x 10.5 mm size fit the battery compartment of my AT&T 2438 handset?

The replacement measures 30.0 x 32.0 x 10.5 mm and weighs 45.0 g, matching the original 80-5074-00-00 pack used in the 2438 and 5600 models.

How can I verify the 3.6 V 300 mAh pack is charging correctly after installation?

Place the handset on its charger; the charge indicator should light and the battery should reach full capacity within the normal charge cycle for a 1.08 Wh Ni-MH cell.

Does the package include a charging cradle or only the 80-5074-00-00 battery itself?

Only the 3.6 V 300 mAh battery pack is supplied; the charging cradle and handset are not included and must be sourced separately.
