Elcom EMN3000 Cordless Phone Compatible Battery 3.6V 600mAh

Elcom EMN3000 / Elite KP3637 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH battery pack for the Elcom EMN3000 and Elite KP3637 cordless phone handsets. It slots into the handset battery compartment and restores power to phones where the original pack no longer holds a charge. Voltage and cell count match the original pack exactly.

• EMN3000 and KP3637 compatibility: Both handsets run on a single 3-cell Ni-MH pack at 3.6V with the same physical footprint (40 × 42 × 13.50mm) and connector orientation. The base station charges at a fixed low-current rate suited to the 600mAh cell capacity — swapping to a different voltage or chemistry will confuse the charge circuit.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on Ni-MH test equipment, confirming the cell balance holds across the full charge window and that capacity reaches rated 600mAh after three conditioning cycles.
• First charge on Ni-MH cordless packs: After installing, seat the handset in the base for a full 16-hour charge before first use. Ni-MH cells shipped in partial-discharge storage need a slow overnight charge to reach rated capacity — a short first charge leaves the cells unevenly conditioned and talk time will appear low for several cycles.

Why the EMN3000 base station shows no charge light on a new battery

Ni-MH packs lose voltage in storage. If the cell voltage drops below roughly 0.9V per cell, the base station's charge circuit may not detect a valid battery and won't start the charge cycle. This shows as a blank or error indicator on the base. To recover, briefly connect the pack to a standalone Ni-MH charger at a low rate (around 60mA) to bring each cell above 1.0V, then return the handset to the base — the charge indicator should activate within a few minutes.

Handset loses DECT pairing after battery replacement

Removing the battery from a DECT handset clears the volatile memory that stores the base station pairing. The handset powers on but shows no signal or fails to connect to the base. This is not a battery fault — it is a standard behaviour when power is fully removed. Re-register the handset using the pairing button on the base station, following the steps in the EMN3000 manual (typically: hold the base registration button for 5 seconds, then confirm on the handset).
