It replaces OEM part number CTP950, fitting directly into the handset battery compartment. Voltage and cell chemistry match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBeocom 4 handset fit:\u003c\/strong\u003e\n    The Beocom 4 base station charges via a contact-based cradle that expects a 2.4V Ni-MH cell pack at a specific physical footprint — 45.25 x 21.00 x 10.70mm. This pack meets both requirements. The base charge circuit won't negotiate with Li-ion voltage profiles, so chemistry match here is not optional.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Beocom 4 base station charge circuit and confirmed the cell voltage climbs correctly through the trickle and full-charge phases. The base station showed no fault indication across all test cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    After fitting the new pack, seat the handset in the base and leave it for a full 16 hours before using it. Ni-MH cordless phone batteries arrive in partial charge from storage — a slow first charge allows all cells to reach rated capacity together and prevents early cell imbalance.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't hit rated capacity on the first charge cycle — this is normal cell behaviour, not a fault with the pack. The Beocom 4 draws a steady current during a call, and a partially conditioned pack will sag voltage sooner than a fully cycled one. Run three to five full charge-and-use cycles through the base station before comparing talk time to the original battery. After conditioning, cell voltage at rest should sit above 2.3V on a full charge.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH pack that has been in storage for several months can drop to a voltage low enough that the base station charge circuit won't recognise it as a valid battery. The Beocom 4 base uses a delta-V detection method — if the starting voltage is too flat, it sees no delta and stalls. Remove the handset, wait 30 seconds, and re-seat it firmly to trigger a fresh detection cycle. If the light still won't activate, check that the handset contacts and base cradle contacts are clean — a resistance across the contact point can prevent the circuit from reading the pack voltage correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339912773722,"sku":"BWCS-BEC400CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339912806490,"sku":"BWCS-BEC400CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339912839258,"sku":"BWCS-BEC400CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BEC400CL-1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/bang-olufsen-beocom-4-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
