It fits handheld drills, impact drivers, and compatible 10.8V platform tools. Capacity is 4000mAh (43.2Wh), sourced to match the OEM part number 0700 996 210.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e07006522 and S 10-A Power platform fit:\u003c\/strong\u003e\n    Both models share the same 10.8V rail, terminal layout, and BMS handshake protocol — this battery communicates cell state data to the tool's electronics the same way the original does.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through motor-start inrush cycles on a 10.8V drill and monitored the BMS response. Overcurrent protection triggered within spec and reset cleanly between pulls with no latching fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning on 10.8V tools:\u003c\/strong\u003e\n    Run the tool at half load for two cycles before applying full torque — this lets the BMS log the motor's inrush current signature and calibrate its overcurrent thresholds before you push the pack hard.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush surge in the 07006522\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill or impact driver, the motor draws a current spike before it reaches running speed — this is inrush current, and it can be several times the steady-state draw. If the BMS hasn't profiled the motor yet, it may interpret that spike as a fault and cut the output. This is more common with a new or recently stored pack. Running two half-load cycles first gives the BMS enough data to distinguish normal inrush from a genuine overcurrent event.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left uncharged for several months can drop below the charger's acceptance voltage threshold — typically around 2.5V per cell. When that happens, the charger sees a voltage too low to confirm a healthy pack and refuses to start a charge cycle. To recover the pack, some chargers have a recovery or boost mode — check your charger manual for a \"wake\" or \"recovery\" function. If your charger lacks this, a compatible charger with a lower acceptance threshold, such as one that accepts packs down to 2.0V per cell, can reinitialise the cells and bring them back into normal charge range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416048468058,"sku":"BWCS-BST411PX-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416048500826,"sku":"BWCS-BST411PX-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416048533594,"sku":"BWCS-BST411PX-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST411PX-1.webp?v=1779759809","url":"https:\/\/batteryweb.com\/products\/wurth-07006522-replacement-battery-108v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
