It fits the CJ10DL jigsaw, DS10DFL drill\/driver, FCG 10DL, FCH 10DL, and more than two dozen additional models in the same voltage family. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e10.8V platform compatibility:\u003c\/strong\u003e\n    All listed models share a common 10.8V rail, identical terminal layout, and the same BMS handshake protocol. The pack slots into any tool or charger built for the BCL1030 \/ BCL1015 footprint without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Hitachi BCL1015 charger. The BMS registered cell balance correctly on the first cycle, and overcurrent protection tripped at the expected threshold during a deliberate inrush test — then reset cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush break-in on first use:\u003c\/strong\u003e\n    Run the tool at half load for the first two cycles before full-torque applications. This lets the BMS profile the motor's inrush current draw and calibrate its overcurrent thresholds before you hit the pack with a hard fastening sequence.\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 in the CJ10DL and DS10DFL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 10.8V Hitachi tools draw a sharp current spike the instant the trigger closes — sometimes three to four times the steady-state draw. A fresh pack or one that has sat in storage may have cells at slightly uneven voltages, and the BMS can interpret that inrush spike as an overcurrent fault and cut the output immediately. The fix is to complete one or two light-load cycles first so the BMS maps the cell balance and sets appropriate thresholds. After conditioning, the same trigger pull that tripped the pack will pass through without interruption.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows no response or blinks fault on a new pack from storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during shipping and warehouse storage. If any cell drops below roughly 2.5V, the BCL1015 or BCL1030 charger will refuse to begin a standard charge cycle and may blink a fault code instead of cycling through green. Some Hitachi chargers include a recovery mode — insert the pack, hold it in the dock for 60 seconds, then remove and reinsert it to trigger the low-voltage recovery routine. If the charger accepts the pack after that, allow a full uninterrupted charge before use; the resting voltage after a full charge should read between 12.4V and 12.6V across the terminal pins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416014061658,"sku":"BWCS-HTB103PH-1","price":84.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416014094426,"sku":"BWCS-HTB103PH-2","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416014127194,"sku":"BWCS-HTB103PH-3","price":109.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTB103PH-1.webp?v=1779759462","url":"https:\/\/batteryweb.com\/products\/hitachi-cj10dl-replacement-battery-108v-4000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
