It fits directly into the battery compartment and connects to the same contacts as the original pack. Voltage and cell chemistry match the base station's charging circuit exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCTP8200, CTP8250, CTP8800, and PM38BAT compatibility:\u003c\/strong\u003e\n    All four models share the same 3.6V single-cell NiMH rail, connector pitch, and physical footprint — one pack covers the full range without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the base station charging circuit and confirmed the BMS accepted charge from the first dock. Charge current stayed within the trickle-charge window the base station expects from a NiMH cell.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells in cordless phones are shipped partially discharged — skipping this slow first charge prevents the pack from reaching its rated 700mAh capacity.\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 rated after replacing the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells don't deliver full capacity on cycle one. The electrodes need three to five full charge-discharge cycles before the chemistry stabilises at its rated output. If talk time feels short in the first few days, that's normal cell conditioning — not a faulty pack. Run the handset down fully and return it to the base each time, and capacity will increase noticeably by cycle three.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge or error light with new pack installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH packs stored before sale can drop below 3.0V, which some Coby base stations won't recognise as a valid battery. The base expects to see a cell voltage above its detection threshold before it opens the charge circuit. If the charge indicator stays off, remove the handset, wait 10 seconds, and re-seat it firmly — this triggers the base to re-sample the battery voltage. If that fails, check that the handset contacts are clean and making full contact with the base pins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339964121178,"sku":"BWCS-CPJ464CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339964153946,"sku":"BWCS-CPJ464CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339964186714,"sku":"BWCS-CPJ464CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPJ464CL-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/coby-ctp8200-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
