About this replacement
Kaba Programmer 1460 — 2.4V Ni-MH Replacement Battery (1460-16)
This is a 2.4V, 2000mAh Ni-MH replacement battery for the Kaba Programmer 1460 handheld door lock programming device. It fits the programmer used to configure and manage electronic door locks in commercial and institutional access control systems. OEM part numbers 1460-16 and 132-512886 both reference this battery.
- Programmer 1460 fit: The 1460 programmer uses a fixed 2.4V Ni-MH cell pack at this form factor — 52mm × 29.35mm × 15mm. Any voltage mismatch or dimensional deviation causes the programmer to fail to boot or corrupts lock configuration sessions mid-write.
- Bench tested on actual hardware: We ran this cell through full charge-discharge cycles and confirmed the BMS holds stable output across the Programmer 1460's communication bursts to the lock interface. No voltage sag was detected during active data write sequences.
- Post-replacement programmer initialisation: After fitting this battery, power cycle the Programmer 1460 and allow it to complete its internal self-check before initiating any lock configuration session. Some firmware versions require a full boot sequence to re-establish communication protocols with the connected lock hardware.
Why the Programmer 1460 drops connection mid-configuration session
Ni-MH cells degrade unevenly across the two-cell pack when one cell holds less capacity than the other — a condition called cell imbalance. During a configuration write, the programmer draws a short burst of current that the weaker cell cannot sustain, causing the pack voltage to sag below the device's minimum operating threshold. The programmer interprets this as a low-battery shutdown and terminates the session, potentially leaving the lock in a partially programmed state. Replacing the full cell pack rather than individual cells is the only way to restore matched capacity across both cells.
Programmer 1460 powers on but shows low-battery warning immediately after battery replacement
A Ni-MH battery shipped in long-term storage self-discharges to approximately 1.0V per cell, which sits below the Programmer 1460's low-battery detection threshold of roughly 2.2V for the pack. The device reads this resting voltage on first boot and flags the warning before the battery has had any charge applied. Connect the programmer to its charger and allow a full charge cycle to complete — the warning clears once the pack reaches 2.4V. Do not attempt a lock programming session until the charger indicates a full charge.
