It fits the GBH 24VFR, 11225VSR, 11225VSRH, and 0 611 260 539 platform, among others. Voltage and pack geometry match the original Bosch specification — no adapters needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGBH 24VFR platform fit:\u003c\/strong\u003e\n    These models share a 24V Ni-MH rail with a common battery bay locking tab and contact pitch. The BMS handshake uses the same thermistor line across this generation, so the charger reads pack temperature correctly without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a GBH 24VFR rotary hammer through repeated trigger pulls. The BMS held the overcurrent threshold steady across cold and warm starts, and the charger's delta-V detection cut off cleanly at full charge each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRotary hammer load cycling:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque applications. This lets the BMS profile the motor inrush current draw before locking in its overcurrent protection thresholds — skipping this step can cause nuisance trips on heavy chiselling.\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 trigger-pull inrush during rotary hammer operation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eRotary hammers pull a sharp current spike the moment the trigger closes — far above steady running current. A new Ni-MH pack, especially one shipped at low state of charge, has higher internal resistance than a conditioned cell. That resistance amplifies the voltage sag at the BMS sense point, and the controller reads it as an overcurrent event. Two or three break-in cycles at moderate load let the cells warm and the internal resistance drop, bringing the inrush spike back inside the BMS trip window.\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\"\u003eBosch 24V Ni-MH chargers use delta-V detection — they need to see a rising voltage curve to confirm the pack is accepting charge. If the pack self-discharged below roughly 18V during storage, the charger sees no rising curve and stalls at the detection phase, often showing a steady or blinking fault LED. The fix is a brief manual trickle: some Bosch chargers have a refresh or recovery mode; if yours does not, a compatible universal charger set to 200–300mA Ni-MH trickle for 30 minutes is enough to raise the pack voltage above the charger acceptance threshold. Once the cells are above that floor, slot the pack back into the Bosch charger and the normal charge cycle will begin.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416084906074,"sku":"BWCS-BST019PW-1","price":142.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416084938842,"sku":"BWCS-BST019PW-2","price":168.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416084971610,"sku":"BWCS-BST019PW-3","price":188.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST019PW-1.webp?v=1779760222","url":"https:\/\/batteryweb.com\/products\/bosch-0-611-260-539-replacement-battery-24v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
