Replacement Ni-MH battery for cordless phones

This 3.6V 600mAh Ni-MH pack replaces the original battery in compatible Southwestern Bell handsets. It matches the factory voltage and capacity so the phone charges and runs exactly as designed. The cell is new and tested to the same specifications as the OEM part. Safety circuits guard against overcharge, over-discharge, over-voltage and short circuits.

Compatibility checklist for buyers

The pack fits models FF718, FF720, FF1712, FF1762, FF727, GH3028 and FF1185. Buyers with a different handset or a battery that uses another voltage or chemistry should look elsewhere. The physical size is 42.45 x 29.77 x 14.37 mm and the weight is 87.7 g; verify the compartment space before ordering. No charger is included in the package.

Voltage and capacity define the fit

The decisive specification is the 3.6V nominal voltage combined with 600mAh capacity (2.16 Wh). If the original battery shows different values the phone will not operate correctly. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS.

Questions about this item

Will the Estry FF718 fit the same handset slot as my original Southwestern Bell FF720 battery?

Yes, the FF718 is built to the same 42.45 x 29.77 x 14.37 mm dimensions and 3.6 V 600 mAh rating as the FF720, so it seats directly in the existing compartment.

How can I confirm the Estry FF718 is charging correctly after I install it?

Place the handset on its base; the charge LED should illuminate and the battery will reach full capacity within the normal charge cycle for a 3.6 V 600 mAh Ni-MH pack.

Does the Estry FF718 package include a charging cradle or only the battery itself?

Only the replacement battery is supplied; the charging cradle and handset are existing hardware you already own.
