It fits the handheld and stick vacuum models that use this OEM part number. The cell pack matches the original voltage rail and connector format used on these units.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e12010776 platform fit:\u003c\/strong\u003e\n    These Bosch cordless vacuums share a fixed 14.4V Ni-MH architecture with a direct connector and BMS handshake tied to cell chemistry. Substituting a different chemistry or voltage causes the charger to reject the pack or the vacuum's motor controller to run out of spec.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the vacuum's motor load profile and confirmed the BMS held stable through both normal suction draws and the higher-current spikes that occur when the motor fights partial blockages. Cell temperature stayed within safe range across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on Ni-MH vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock indefinitely. Ni-MH cells on continuous trickle charge develop capacity fade significantly faster than cells charged only when depleted. Charge to full, then remove the vacuum from the dock.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells show voltage sag under sustained motor load before the pack is actually depleted. On the Bosch 12010776, this shows up as weakening suction while the indicator still reads mid-charge. A partially blocked filter makes this worse — the motor draws more current to compensate, which deepens the voltage sag and triggers what feels like premature battery failure. Clean or replace the filter first, then reassess actual battery performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out on thick carpet and then recovering seconds later\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, clogged nozzle, dense carpet pile — the motor pulls sustained current above the BMS threshold, and the pack disconnects to protect the cells. The brief recovery you see is the BMS resetting after the thermal or current condition clears. Check the filter and nozzle for restriction before assuming the battery is at fault. If the cutout persists on a clean filter, verify the pack is reading above 12.8V under light load before concluding the cells have degraded.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426466627674,"sku":"BWCS-BSC120VX-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426466660442,"sku":"BWCS-BSC120VX-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426466693210,"sku":"BWCS-BSC120VX-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSC120VX-1.webp?v=1779933285","url":"https:\/\/batteryweb.com\/products\/bosch-12010776-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
