OEM part number BC102549 — also cross-references 300MAH0735, 1-32-125C, and 85H. It fits the handset battery compartment directly and restores the handset to normal operation when the original cell has degraded.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCWD600 \/ CWD700 \/ CWD2000 \/ CWD3000 compatibility:\u003c\/strong\u003e\n    All four models share the same 3.6V Ni-MH cell format, connector pinout, and base station charging circuit. One battery covers the full range — no wiring adapters or housing modifications needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the CWD600 base station and confirmed the BMS accepted the charge handshake without error. Voltage at full charge measured within the expected range for Ni-MH at this capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on a NiMH cordless handset:\u003c\/strong\u003e\n    Place the handset in the base immediately after fitting and leave it for a full 16 hours before first use. Ni-MH cells ship partially discharged and need a slow, uninterrupted first charge to reach rated capacity — a short top-up charge will leave the cell short of its full 300mAh.\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 original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver full rated capacity on the first charge cycle — this is normal chemistry, not a fault. The cell needs three to five full charge-and-use cycles before it reaches 300mAh. Each cycle should run the handset down to low-battery cutoff before returning it to the base. After five cycles, talk time should stabilise at the rated level.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after fitting new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose voltage during storage. If the cell voltage drops low enough, the base station charging circuit may not recognise it as a valid battery and will withhold charge. Remove the handset, leave it off the base for 30 seconds, then re-seat it firmly — the base needs a clean contact reset. If the error light persists, check that the handset contacts and base cradle contacts are clean and making full contact. A brief wipe with a dry cloth on both contact points is enough to restore continuity and allow charging to begin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339886624858,"sku":"BWCS-CWD600CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339886657626,"sku":"BWCS-CWD600CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339886690394,"sku":"BWCS-CWD600CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CWD600CL-1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/cable-wireless-cwd600-replacement-battery-36v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
