It replaces OEM part numbers BT 4024 and 270401020. Fits the original battery slot and works with the same charger used for the factory pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-model compatibility across the 24 Li platform:\u003c\/strong\u003e\n    The BLA 24 Li, C 24 Li, H 24 Li, and MT 24 Li all share the same 24V battery rail, connector pinout, and BMS handshake protocol — that is why one pack covers all four. Swapping between tools on the same platform works without reconfiguration.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack under repeated motor-start inrush cycles on a 24V drill platform. The BMS handled the current spike on trigger pull without tripping, and cell voltage recovered cleanly after each discharge event.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst two cycles on a new pack:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This lets the BMS log the motor inrush current profile and set accurate overcurrent thresholds before you push it into heavy drilling or cutting.\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 24 Li drill and saw range\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill or circular saw, the motor draws a surge of current before it reaches operating speed. On 24V Li-ion packs, this inrush spike can briefly exceed the BMS overcurrent threshold if the cells are cold or if the pack has been sitting discharged. The BMS interprets this as a fault and shuts the output rail down in under a millisecond. A short rest of 10–15 seconds, then a slow trigger pull, usually resets the latch and lets the pack recover without a charger cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red and refusing to accept the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMost Alpina 24V chargers have a minimum acceptance voltage below which they will not begin a charge cycle — typically around 16–18V on a 24V pack. If the pack has self-discharged during storage, cell voltage can drop below that threshold, and the charger signals the refusal with a continuous or blinking red LED. Connect the pack and leave it on the charger for 5–10 minutes — some chargers run a trickle pre-charge mode that brings the cells back above the acceptance floor before switching to normal charge. If the red LED persists past 15 minutes, check cell voltage at the terminal with a multimeter; a reading below 14V indicates the pack has deep-discharged past recovery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416007704666,"sku":"BWCS-GWP240PW-1","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416007737434,"sku":"BWCS-GWP240PW-2","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416007770202,"sku":"BWCS-GWP240PW-3","price":115.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/alpina-bla-24-li-replacement-battery-24v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
