It replaces the original pack when capacity fades and the vacuum no longer holds a useful charge. Capacity is rated at 48.96Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eU100, U100 Plus, and U80 Pet fit:\u003c\/strong\u003e\n    All three models share the same 14.4V platform, battery bay dimensions, and connector format. The BMS communication protocol is consistent across this range, so one pack covers all three without modification.\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 U100 platform. The BMS handled motor start current without tripping, and cell voltage held within expected range under continuous suction load across multiple cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the U100:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between uses. Continuous dock charging applies a low-level trickle that accelerates capacity fade in Li-ion cells. Charge to full, remove the vacuum from the dock, and return it only when the pack is depleted.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the battery can sustain at the current state of charge. A partially blocked filter forces the motor to work harder, pulling amps above the BMS's sustained-load threshold. The BMS responds by reducing output to protect the cells, which the vacuum presents as weak suction rather than a low-battery warning. Clear the filter and check for blockages at the brush head before assuming the battery is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a flat battery. When suction is restricted — blocked filter, clogged hose, or a jammed brush roll — the motor current spikes sharply. The BMS cuts power to prevent cell damage, then resets once current drops. The few-second recovery is the BMS re-enabling the output after the fault clears. Clean the filter and brush roll, then confirm the pack voltage reads at least 14.0V on a multimeter before continuing use.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427963797594,"sku":"BWCS-LTR320VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427963830362,"sku":"BWCS-LTR320VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427963863130,"sku":"BWCS-LTR320VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-LTR320VX-1.webp?v=1779933588","url":"https:\/\/batteryweb.com\/products\/okami-u100-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
