It fits the FT3806, FT3808, FTH916, and FTH918 models. The cell matches the voltage, capacity, and physical dimensions of the original factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFT3806, FT3808, FTH916, FTH918 compatibility:\u003c\/strong\u003e\n    These four handsets share the same 3.6V battery bay, connector pin layout, and charge circuit. One pack covers all four models without any modification.\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 cordless phone test rig. The BMS accepted charge current from a standard DECT base and held voltage within the expected range across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on Ni-MH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it there for a full 16 hours before first use. Ni-MH cells shipped from storage are partially discharged. A slow first charge lets the cells reach rated capacity evenly across all three cells in the pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after installing a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT base stations use a voltage threshold to detect whether a battery is present and ready to accept charge. A new Ni-MH pack sitting in a warehouse for several months can drop below that threshold — typically around 3.0V — and the base reads it as absent or faulty. The fix is a brief manual top-up: many users find placing the handset firmly in the cradle for 30 minutes and reseating it once clears the error. If the light still does not activate, check that the handset contacts are clean and making full contact with the base pins.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected for the first several uses\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not deliver rated capacity on the first discharge cycle. Capacity builds gradually over the first three to five full charge-and-discharge cycles as the cell chemistry stabilises. If talk time feels short after the first day, that is normal behaviour — not a fault with the pack. Run three or four complete cycles through the base station before comparing performance against the original battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339984175194,"sku":"BWCS-CPB483CL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339984207962,"sku":"BWCS-CPB483CL-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339984240730,"sku":"BWCS-CPB483CL-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB483CL-1.webp?v=1778367001","url":"https:\/\/batteryweb.com\/products\/toshiba-ft3806-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
