Telia Free 3000 Replacement Battery NS-3098 2.4V 700mAh

Telia Free 3000 / Free 3001 — 2.4V Ni-MH Replacement Battery (NS-3098)

This is a 2.4V 700mAh Ni-MH replacement battery for the Telia Free 3000 and Free 3001 cordless DECT handsets. It replaces OEM part NS-3098 (also listed as BC101590). When the original cell degrades and the handset stops holding a charge, this pack restores operation to the handset.

• Free 3000 and Free 3001 compatibility: Both models share the same 2.4V two-cell NiMH pack, connector orientation, and physical footprint — 6.00 × 33.00 × 48.00mm. The base station charging circuit expects NiMH chemistry at this voltage, so swapping chemistry type would cause a charging fault.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on the Free 3000 base station. The BMS accepted the pack without an error light from cycle one, and voltage held stable under RF transmit load through multiple test calls.
• First charge on NiMH cordless packs: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phones arrive partially discharged from storage and need a slow initial charge to reach rated capacity — skipping this shortens the usable charge significantly on early cycles.

Talk time shorter than the original battery after replacement

NiMH cells don't deliver rated capacity on the first charge cycle — this is normal chemistry behaviour, not a defect. The cells need three to five full charge-discharge cycles before they reach 700mAh. Each cycle should run the handset until it signals low battery, then return it to the base for a full charge. By cycle five, capacity stabilises and talk time matches what the original pack delivered when new.

Base station shows no charge or error light after fitting new pack

This happens when the replacement pack arrives with voltage too low for the base station's acceptance threshold after extended storage. The base detects a voltage below its minimum and refuses to start the charge cycle. Place the handset in the base and hold it firmly seated — some Free 3000 bases require a firm contact to initialise. If the error persists after five minutes, remove the battery, leave it out for 30 seconds, refit it, and reseat the handset. The base should accept the pack once terminal voltage rises slightly from contact warmth and begins the trickle charge phase.
