Uniden BT-1021 NiMH AAA 3-pack

This three-pack of 600 mAh 2.4 V nickel-metal-hydride AAA cells replaces the original batteries in compatible Uniden cordless handsets. It is intended for households or small offices that need to refresh multiple handsets at once.

Replaces BT-1016, BT-1008, BT-1025 and CPH-515B

The pack directly substitutes several earlier Uniden battery codes, so one purchase covers handsets that originally shipped with any of those part numbers. No additional chargers or adapters are included in the box.

Simple drop-in installation

Each cell fits the standard AAA compartment in the listed handsets; polarity markings on the battery and handset prevent incorrect insertion. The only common issue is attempting to use the pack in models not shown in the compatibility list, which will result in a physical or electrical mismatch.

Questions about this item

How often will these 600 mAh NiMH AAA cells need replacing under normal cordless phone use?

Typical NiMH packs last two to three years before capacity drops enough to shorten talk time; swap all three at once to keep the handset balanced.

What limits continuous talk time when the handset is in constant use?

The 600 mAh rating sets the energy ceiling; once the cells discharge to the handset's low-voltage cutoff the call ends.

Do the batteries get warm or draw extra power during an all-day conference call?

NiMH chemistry stays near room temperature during normal discharge and the handset's charger regulates current, so no noticeable heat or power spike occurs.
