Answer Call Ranger 2000 Ni-MH Cordless Phone Battery 3.6V 600mAh

Answer Call Ranger 2000 — 3.6V Ni-MH Replacement Battery

This is a 3.6V, 600mAh Ni-MH battery for the Answer Call Ranger 2000 cordless phone handset. It slots into the handset battery compartment and restores wireless talk and standby function. Use this when the original pack no longer holds a charge or the handset dies faster than expected.

• Ranger 2000 handset fit: The Ranger 2000 uses a compact single-cell Ni-MH pack running a 3.6V rail to power both the DECT radio and the handset processor. This replacement matches that voltage and the physical cell arrangement — 40 × 42 × 13.50mm — so the compartment lid closes correctly and the contact tabs align.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a Ni-MH-compatible charger, confirming the cell accepts charge current without heat spikes and holds voltage through the discharge curve without premature cutoff.
• First-charge conditioning for Ni-MH handsets: Place the handset in the base cradle for a full 16 hours before the first call. Ni-MH cells shipped in storage state will not reach rated 600mAh capacity on a short first charge — the slow trickle cycle from the base is what brings them up to spec.

Base station showing no charge light after fitting a new Ni-MH pack

Ni-MH batteries lose voltage during storage. If the pack voltage drops low enough, the Ranger 2000 base station's charge circuit may not detect the battery as a valid load and will show no indicator light at all. This is not a faulty battery — it is the base rejecting a pack below its acceptance threshold. Place the handset in the base and leave it undisturbed for at least two hours; most base chargers will begin a recovery trickle once the cell temperature stabilises. If the light still does not appear, check that the handset contacts are clean and the handset is fully seated in the cradle.

Talk time shorter than the original battery after replacement

New Ni-MH cells do not deliver full rated capacity straight out of the box. The 600mAh rating is reached after three to five full charge-discharge cycles, not on the first use. For the first few days, the handset may cut out earlier than expected — this is normal cell conditioning behaviour, not a defective pack. Run the handset until it prompts a low battery warning, return it to the base for a full charge, and repeat; by cycle four or five, talk time will reach the rated level.
