It fits the BP800 portable transmitter\/receiver unit used in HME wireless communications setups. OEM part numbers C10326 and K05645 both cross to this cell pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBP800 beltpack compatibility:\u003c\/strong\u003e\n    The BP800 uses a 4.8V Ni-MH cell pack because the beltpack's radio transmitter and audio circuits share a single power rail. That voltage and chemistry combination is dictated by the connector pinout and the onboard charge controller — substituting a different chemistry trips the base station's charge termination logic.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the BP800 platform. The BMS accepted charge termination correctly from the base station, and the pack held voltage under combined DECT radio and audio draw without dropping into low-voltage cutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBase station first-charge protocol:\u003c\/strong\u003e\n    Seat the beltpack in the HME base station and let it complete one uninterrupted full charge before using it on a call. The base station logs the new cell during this cycle and calibrates its talk-time indicator — skipping this step causes inaccurate charge-level readings from the first use onward.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the BP800 cuts out mid-transmission on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BP800 draws current simultaneously from the DECT radio module and the audio circuit during active calls. On a new or storage-discharged Ni-MH pack, this combined load can pull the cell voltage below the beltpack's cutoff threshold before the battery is truly depleted. This is a delivery voltage issue, not a capacity fault. One full charge cycle through the base station stabilises the internal cell resistance and the voltage sag under load drops to normal levels.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows full charge but beltpack shuts off after short use\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH pack shipped at storage voltage often reads as fully charged on the base station's indicator after only a partial charge cycle — the charger detects a voltage plateau and terminates early. The actual cell capacity at that point is well below rated. Remove the beltpack, let it discharge fully through normal use until it shuts off, then return it to the base for a complete charge cycle. After one full discharge-charge cycle, the pack reaches its rated 2000mAh and the base station indicator becomes accurate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428117282906,"sku":"BWCS-HMP800TS-1","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428117315674,"sku":"BWCS-HMP800TS-2","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428117348442,"sku":"BWCS-HMP800TS-3","price":47.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HMP800TS-1.webp?v=1779934164","url":"https:\/\/batteryweb.com\/products\/hme-bp800-beltpack-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
