This pack fits the exact models shown in the compatibility list such as 26920GE1, 29921, 27730GE2 and BT31 among others. Buyers with a different brand of phone or a model number not shown should look elsewhere because the connector and form factor will not match.

1200mAh capacity for typical daily talk time

At 1200mAh the battery provides several hours of talk time and days of standby on a single charge for the supported handsets. Heavy users who spend many hours on calls each day may find the capacity runs out before the evening and would need a higher-capacity alternative if one exists for their model.

Questions about this item

Does the 50.43 x 42.54 x 14.4 mm size need any adapter to fit my cordless phone?

The battery matches the original dimensions of 50.43 x 42.54 x 14.4 mm, so it fits the listed models without an adapter.

Will the 3.6 V 1200 mAh rating work with the charging base from my older handset?

Yes, the 3.6 V voltage and 1200 mAh capacity match the original specs, so the existing charging base charges it normally.

How can I confirm the 4.32 Wh pack is functioning after I install it?

After installation, place the handset on its base; a steady charge indicator and normal talk time show the 4.32 Wh pack is working.
