About this replacement
Alecto DBX-111 — 2.4V Ni-MH Replacement Battery (P001994)
This is a 2.4V, 700mAh Ni-MH battery for the Alecto DBX-111 audio baby monitor. It powers the portable parent unit — the handheld receiver you carry around the house. When the original pack loses capacity after repeated charge cycles, the parent unit stays tethered to the charger. This battery restores cordless operation.
- DBX-111 parent unit fit: The DBX-111 parent unit runs on a compact 2.4V Ni-MH cell with a specific footprint — 44.60 × 20.91 × 10.47mm. The P001994 reference confirms connector and housing compatibility with this unit. No modification needed.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the DBX-111 parent unit. The BMS accepted the charge without fault codes, and the unit held a stable audio link throughout testing. Capacity held close to the rated 700mAh across multiple cycles.
- Wireless link after battery swap: When the parent unit loses power completely during a battery swap, it drops its wireless pairing with the transmitter unit. Re-pair the two units manually after fitting the new battery — hold the pair button on the transmitter until the parent unit confirms the link.
Parent unit range reduced after fitting a new battery
The DBX-111 parent unit's radio transmitter draws from the same 2.4V cell. At low charge, the radio stage gets less voltage than it needs to reach full output power. That narrows the effective range before you hit static or signal dropout. Charge the new battery fully before first use — the radio performs noticeably better at full cell voltage than at 60–70% charge.
Parent unit screen stays on overnight and battery is flat by morning
A 700mAh Ni-MH cell with the backlit screen active all night is a sustained draw the pack was not sized to handle indefinitely. The screen-on state pulls significantly more current than audio-only mode. Go into the DBX-111 menu and enable the screen timeout or VOX-triggered display setting. That alone cuts overnight drain and extends the charge between top-ups.
