It runs the same voltage rail and connector footprint as the original Hitachi pack. Capacity is 3000mAh (108Wh) — sourced from the product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDH 36DAL and DH36DL platform fit:\u003c\/strong\u003e\n    Both models share the same 36V slide-rail connector, BMS handshake protocol, and charge acceptance voltage. One battery covers both tools — no adapter or firmware change needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on a DH 36DAL under repeated motor-start loads. The BMS handled inrush current spikes without tripping overcurrent protection, and cell balancing completed normally at end of charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in load cycling:\u003c\/strong\u003e\n    On first use, run the drill at half load for two full discharge-charge cycles before driving large-diameter bits or maximum torque applications. This lets the BMS profile the motor's inrush current draw and set accurate overcurrent thresholds before you push the tool 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 with the DH 36DAL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery trigger pull on a cordless drill generates a brief inrush spike — current demand jumps sharply before the motor reaches speed. On a new or freshly charged 36V pack, this spike can exceed the BMS overcurrent threshold if the protection parameters haven't been calibrated to the motor's draw profile. The pack shuts down instantly as a protective measure, not a fault. Running two half-load break-in cycles allows the BMS to learn the motor's start signature and widen the overcurrent window accordingly.\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\"\u003eIf the DH 36DAL battery has been in storage for several months, individual cells can drop below the charger's minimum acceptance voltage — typically around 2.5V per cell. The charger sees a voltage below its intake threshold and either blinks an error or does nothing at all. Place the pack on the charger, wait 10–15 minutes, then remove and re-seat it firmly — some chargers require a second handshake once the trickle charge wakes the cells. If cells recover above the acceptance floor, the charger will shift into normal charge mode; check that the indicator moves from red to steady green within 30 minutes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416039587930,"sku":"BWCS-HTB362PW-1","price":155.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416039620698,"sku":"BWCS-HTB362PW-2","price":183.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416039653466,"sku":"BWCS-HTB362PW-3","price":205.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/batteryweb.com\/products\/hitachi-dh-36dal-replacement-battery-36v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
