It fits directly into the IP65 handset and restores power to calls and standby operation. OEM part numbers covered: 5010808000 and 5010808030.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIP65 handset fit:\u003c\/strong\u003e\n    The IP65 uses a single-cell Li-ion pack running a 3.7V nominal rail. Both OEM part numbers (5010808000 and 5010808030) share the same cell footprint, connector pinout, and BMS communication protocol — this replacement covers both revisions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the IP65 handset. The BMS accepted charge current from the base station without triggering a protection cutoff, and the handset reported battery status correctly throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the IP65:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base cradle and leave it for a full uninterrupted charge before taking any calls. Li-ion cells shipped in partial-charge storage states need one complete charge cycle to let the BMS calibrate its capacity tracking correctly.\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 fitting the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Li-ion cell arrives from storage at reduced state of charge, and the BMS capacity register is not yet calibrated to the new cell. Until the BMS has completed one full charge-to-discharge cycle, the handset's fuel gauge will under-report available capacity. Run one complete cycle — full charge from base, then use the handset until the low-battery indicator appears — and the reported and actual capacity will align. Rated capacity is 700mAh at 3.7V nominal.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset not pairing with base station after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRemoving the battery from a DECT handset cuts all power to the DECT module, which can wipe the pairing registration stored in volatile memory. The base station and handset then no longer recognise each other on the next power-up. To fix this, re-register the handset manually using the pairing or registration button on the base station — the procedure is in your IP65 user manual. Once re-registered, the handset resumes normal DECT operation on the correct channel.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339897798746,"sku":"BWCS-AYD420CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339897831514,"sku":"BWCS-AYD420CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339897864282,"sku":"BWCS-AYD420CL-3","price":29.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/mobilteil-ip65-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
