It replaces the original rechargeable cell that powers the handset away from the base station. When the original pack no longer holds a charge, swapping it restores normal cordless operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMD500 and Micro DECT handset fit:\u003c\/strong\u003e\n    These models share the same 2.4V two-cell NiMH pack configuration, connector pinout, and physical footprint — 50.25 × 28.09 × 14.41mm. The base station charges at a voltage rail matched to this chemistry, so no adapter or modification is needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a NiMH-compatible analyser. The BMS accepted charge current without rejection, and cell voltage held within spec across repeated cycles with no thermal anomaly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Place the handset in the base for a full 16 hours before first use. NiMH cordless phone packs shipped in storage discharge and need a slow full charge to reach rated capacity — a short first charge will leave the cells underformed.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge indicator not lighting after fitting a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries lose voltage during storage. If the resting voltage drops far enough, the base station's charge circuit may not recognise the pack as a valid load and will show no charge light or an error state. This is not a fault with the battery or the base. Seat the handset firmly in the cradle and leave it for 30–60 minutes — once the trickle stage raises the pack above approximately 2.0V, the base will switch to normal charging mode and the indicator will activate.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time noticeably shorter than the original battery for the first few uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA new NiMH cell does not deliver full rated capacity on the first cycle. It typically takes three to five full charge-discharge cycles before the cells reach 1200mAh. Using the handset until it beeps low, then returning it to the base for a complete charge each time, works through this conditioning faster. By cycle five, talk time should match or exceed what the worn original pack provided.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339987877978,"sku":"BWCS-BTM500CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339987910746,"sku":"BWCS-BTM500CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339987943514,"sku":"BWCS-BTM500CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BTM500CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/binatone-md500-replacement-battery-24v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
