Audioline DECT 1000 Replacement Battery 3.6V 700mAh

Audioline DECT 1000 — 3.6V Ni-MH Replacement Battery (60AAAH3BMU)

This is a 3.6V 700mAh Ni-MH rechargeable battery for the Audioline DECT 1000 cordless phone handset. It replaces OEM part 60AAAH3BMU and restores charge capacity to the handset when the original cell no longer holds sufficient charge. Physical dimensions are 45.01 × 31.22 × 10.05mm — confirm fit against your existing pack before installing.

• DECT 1000 handset fit: The DECT 1000 handset uses a single AAA-format three-cell Ni-MH pack at 3.6V. The base station's charging circuit is tuned to this voltage and cell chemistry — swapping to a different voltage or chemistry will prevent the base from charging correctly.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a Ni-MH test rig. The BMS accepted charge from a standard DECT base station charger without error, and voltage held stable at 3.6V nominal through the discharge curve.
• First charge after installation: After fitting, seat the handset in the base and leave it for a full 16 hours before use. Ni-MH cells in DECT handsets arrive partially discharged from storage — a slow first charge lets all three cells balance and reach rated capacity.

Talk time shorter than the original battery after replacement

Ni-MH cells do not reach full rated capacity on the first charge cycle. The DECT 1000 base station charges at a low trickle current, so the pack needs three to five full charge-and-use cycles before capacity stabilises at the rated 700mAh. During this period, talk time will be noticeably shorter than expected — this is normal cell conditioning, not a fault. Run the handset until the low-battery alert sounds, then return it to the base for a full charge each time.

Base station shows no charge or flashes an error light after swap

When a Ni-MH pack sits in storage, its resting voltage can drop below the threshold the DECT 1000 base station uses to detect a valid battery. The base interprets this as a fault and refuses to begin a charge cycle. Remove the handset, leave it out of the base for 30 seconds, then reseat it firmly — the charging contacts need full contact to read voltage correctly. If the error persists, the pack voltage may be too low for the base to accept; try a brief charge from a standalone Ni-MH charger first to bring the pack above 3.0V, then return it to the base.
