Direct replacement for cordless handsets

The Estry FF-2400 is a 3.6V 700mAh Ni-MH battery built to match the original specifications for Southwestern Bell handsets. It fits models including FF-2400, GH-2400, GH-5810, GH-3210, GH-2400C, GH-3062, GH-5825 and GH-2420. The pack measures 45.6 x 31.3 x 10.6mm and weighs 61.0g.

Upgrades worn original cells

This unit replaces factory packs that no longer hold a full charge or that show reduced talk time. The jump is worth it when the handset dies quickly off the cradle or when the battery warning sounds after only a short period of use. It restores the original 2.52Wh capacity without modification.

Steady output during long calls

Built-in overcharge, over-discharge, over-voltage and short-circuit protection maintains stable voltage across extended conversations. The chemistry delivers consistent current rather than a brief peak, so the handset stays powered through lengthy sessions. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS.

Questions about this item

What are the exact dimensions of the Estry FF-2400 battery so I can check it fits my handset?

How do I install the Estry FF-2400 and which step do people often miss?

Expect roughly one year of service; replace it when talk time drops noticeably, the handset won't hold a charge, or the pack shows any swelling.
