It replaces OEM part numbers BAT411, BAT411A, BAT412A, BAT413A, and the 2 607 336 013 series. Voltage and cell chemistry match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e10.8V platform fit:\u003c\/strong\u003e\n    The GDR, GLI, GMF, GSA, and 67 additional Bosch 10.8V tools share a common battery interface — same voltage rail, same connector, and the same BMS handshake protocol. One pack covers the full platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on the GDR 10.8 V-LI under repeated fastening cycles. The BMS held the voltage rail steady through multiple trigger pulls, with overcurrent protection tripping correctly on deliberate stall tests rather than false-cutting mid-task.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush conditioning:\u003c\/strong\u003e\n    On first use, run the drill at half load for two full discharge-and-charge cycles before pushing maximum torque. This lets the BMS profile the motor inrush current spike and calibrate its overcurrent threshold — reducing nuisance trips on heavy fastening later.\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 in the GDR 10.8 V-LI\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GDR 10.8 V-LI draws a sharp current spike the instant the trigger closes — motor-start inrush can hit three to four times the steady running current for a fraction of a second. A new or recently stored pack has a BMS that has not yet logged that specific motor's inrush signature, so the overcurrent threshold trips early. After two or three full working cycles, the BMS adjusts its cutoff window to match the actual inrush profile of the tool. If the drill cuts out repeatedly on the first trigger pull, this is the cause — not a faulty battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If this pack sat in a warehouse long enough, cell voltage can drop below the charger's acceptance threshold — typically around 2.5V per cell, or roughly 7.5V at the pack level for a 10.8V three-cell series pack. When the charger sees voltage below that threshold, it refuses to begin a charge cycle and may blink red or show no activity at all. Place the pack in the charger and leave it connected for 10–15 minutes — most Bosch 10.8V chargers include a recovery mode that trickle-charges at low current to bring cells back above the 2.5V floor before switching to normal charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416048566362,"sku":"BWCS-BST411PX-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416048599130,"sku":"BWCS-BST411PX-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416048631898,"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\/bosch-gdr-108-v-li-replacement-battery-108v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
