About this replacement
Alcatel Mobile Reflexes 200 — 3.7V Li-ion Replacement Battery (3BN67137AA)
This is a 3.7V, 800mAh Li-ion replacement battery for the Alcatel Mobile Reflexes 200 cordless DECT phone. It replaces OEM part number 3BN67137AA. When the original pack can no longer hold a charge, this battery restores the handset to working condition.
- Mobile Reflexes 200 fit: The 3BN67137AA form factor is specific to this handset line. The connector orientation, cell dimensions (58.90 × 45.70 × 14.35mm), and 3.7V nominal voltage match the handset's internal bay and charge circuit exactly.
- Bench tested on actual hardware: We ran this cell through charge acceptance and discharge profiling on the Mobile Reflexes 200 platform. The protection circuit responded correctly to cutoff thresholds, and the base station registered a normal charge state throughout the cycle.
- First charge on the Mobile Reflexes 200: After installing, seat the handset in the base and leave it there for a full 16 hours before making a call. Li-ion cells shipped in partial-charge storage states need one complete slow charge to calibrate correctly with the handset's fuel gauge.
Talk time shorter than expected on the Mobile Reflexes 200 after a battery swap
Replacement Li-ion cells are shipped in a reduced state of charge to meet transport safety limits. The handset's charge controller may read this as a partial pack and terminate the first charge cycle early. Running two to three full charge-and-use cycles forces the controller to recalibrate against the actual 800mAh cell capacity. After those cycles, talk time should align with the original battery's rated performance.
Mobile Reflexes 200 handset not pairing with the base after battery replacement
Removing the battery cuts all power to the handset, including the DECT registration memory on some models. When power is restored, the handset may no longer recognise the base. To re-pair, hold the handset's paging or find button for five seconds while the base is powered, or press the registration button on the base until the handset finds it. Once the pairing tone sounds, place the handset back in the cradle and allow a full charge cycle before use.
