Siemens Gigaset 2000L Replacement Battery NS-3098 2.4V 700mAh

Siemens Gigaset 2000L Series — 2.4V Ni-MH Replacement Battery (NS-3098)

This 2.4V, 700mAh Ni-MH battery replaces the pack in Siemens Gigaset cordless handsets. It fits the Gigaset 2000L, 2011 Pocket, 3010 Pocket (not the 3010 Micro), 2000C Pocket, and several other handsets in the same family. Cross-references include BC101590, C39153-Z7-C3, T266, 8M2BZ, and B3880 / 106483.

• Gigaset 2000-series handset fit: These handsets share the same 2.4V two-cell NiMH bay, connector orientation, and physical footprint. The BMS in the base station expects a NiMH charge curve — this pack matches that profile so the base charges it without triggering a fault light.
• Bench tested on actual hardware: We cycled this pack through charge and discharge on a Gigaset base station. The base accepted the pack immediately, the charge indicator lit correctly, and the BMS completed a full charge cycle without interruption or error state.
• First-charge protocol for NiMH cordless handsets: After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phone packs need that slow initial charge to reach rated capacity — skipping it means the first several cycles will show shorter talk time than expected.

Talk time shorter than the original battery after replacement

NiMH cordless phone packs are not at full capacity straight out of the box. Cells leave storage in a partially discharged state, and the first two to five full charge-discharge cycles are needed to reach rated capacity. This is normal chemistry behaviour, not a fault with the pack. Run the handset through at least three full cycles — full charge in base, then use until the low-battery alert sounds — before judging talk time.

Base station charge light not coming on with the new pack installed

Gigaset base stations check the incoming voltage from the handset before starting a charge cycle. A new NiMH pack that has sat in storage can drop below the threshold the base expects — typically under 2.0V — and the base simply does not initiate charging. Remove the handset, wait 30 seconds, and reseat it firmly to prompt the base to re-check. If the light still does not come on, use a separate NiMH charger to bring the pack up to at least 2.2V, then return it to the base.
