Samsung SP-R6100 Cordless Phone Compatible Battery 2.4V 500mAh

Samsung SP-R6100 Series — 2.4V Ni-MH Replacement Battery (BC102168)

This is a 2.4V, 500mAh Ni-MH rechargeable battery for the Samsung SP-R6100 cordless phone handset. It fits the SP-R6100, SP-R6100pp, SP-R6150, and SP-R6100 Twin handsets. The original battery in these phones degrades with repeated shallow charge cycles, cutting talk time and range well before the handset itself fails.

• SP-R6100 series compatibility: These handsets share the same 2.4V two-cell NiMH pack format, connector pinout, and physical footprint. The BC102168 cross-references cover the full SP-R6100 family, including variants sold under part numbers 82H, CP25, E47H, T304, and T335.
• Bench tested on actual hardware: We ran this pack on the SP-R6100 base station and confirmed the BMS accepted charge immediately. Voltage at the terminals measured 2.4V nominal, and the base station charge indicator responded correctly without error.
• 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 need a slow initial charge to reach rated 500mAh capacity — pulling the handset off too early locks in a lower usable ceiling for that cell pair.

Talk time shorter than the original battery after replacement

NiMH cordless phone batteries don't deliver full rated capacity on the first few cycles — this is normal cell chemistry, not a defect. The first three to five charge-discharge cycles condition the cells and progressively unlock capacity. If talk time still seems short after five full cycles, confirm the handset is seating correctly in the base cradle so charge current is actually reaching the battery contacts.

Base station showing no charge or error light on a new pack

NiMH packs stored before sale self-discharge to a low resting voltage. Some Samsung base stations will not initiate a standard charge cycle if the incoming pack voltage reads below their acceptance threshold. To recover, remove the handset, wait 30 seconds, reseat it firmly, and confirm both cradle contacts are clean and making full contact. If the error clears but reappears, check the pack voltage at the terminals — it should read at or above 2.0V for the base to accept it reliably.
