It replaces OEM part numbers EBM 315, 326263, and 326299. Capacity and voltage match the original spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDB 3DL and NT-series compatibility:\u003c\/strong\u003e\n    These tools share the same 3.6V battery platform, connector footprint, and BMS handshake protocol — one pack covers both the drill\/driver and the nailer lines without adapter hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge-discharge cycles on a DB 3DL2 and monitored BMS response during motor-start inrush. The protection circuit held stable across repeated trigger pulls without nuisance tripping.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNailer-specific load tip:\u003c\/strong\u003e\n    On NT 50GS and NT 65GA nailers, rapid sequential firing cycles the battery harder than drilling does. Allow the pack to rest briefly after extended bursts — back-to-back magazine dumps push cell temperature faster in the nailer's enclosed battery bay than the drill housing does.\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 DB 3DL\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DB 3DL motor draws a brief inrush spike the moment the trigger closes — significantly higher than the steady-state running current. On a depleted or cold cell, this spike can push the BMS overcurrent threshold and cut the pack out instantly. The fix is straightforward: bring the battery to room temperature before use, and avoid starting under full torque load. If the pack has been in storage, run one partial charge cycle before attempting high-resistance fastening tasks.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger Not Recognising the Pack After Extended Storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells that sit unused for several months can drop below the charger's acceptance voltage threshold — typically around 2.5V per cell. When that happens, the charger sees the pack as faulty and refuses to start a charge cycle. Place the pack on the charger and leave it connected for up to 30 minutes; many chargers include a trickle-recovery mode that slowly raises cell voltage before switching to standard charge. If the charger still shows no activity after 30 minutes, check individual cell voltage — any cell reading below 2.0V indicates permanent over-discharge damage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416074059866,"sku":"BWCS-HTB315PW-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416074092634,"sku":"BWCS-HTB315PW-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416074125402,"sku":"BWCS-HTB315PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTB315PW-1.webp?v=1779760117","url":"https:\/\/batteryweb.com\/products\/hitachi-db-3dl-replacement-battery-36v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
