It matches OEM part numbers 2 607 336 037, 2 607 336 038, 2 607 336 194, and 2 607 336 206. The pack slots directly into the PSR 14.4 base and communicates with the tool's onboard BMS as a standard replacement.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePSR 14.4 LI and LI-2 compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V sliding-rail connector and BMS communication protocol. The LI-2 added a fuel gauge LED strip on the pack itself — this replacement supports that display circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through five full charge-discharge cycles on a PSR 14.4 LI-2 chassis. The BMS registered correct cell voltage handshake with the Bosch AL 1404 charger on each cycle, and overcurrent protection triggered at expected thresholds during simulated stall conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush conditioning on first use:\u003c\/strong\u003e\n    On the first two cycles, run the drill at half throttle on light fastening tasks before pushing full torque. This gives the BMS time to establish accurate overcurrent thresholds for the motor's start-up inrush current before you hit large-diameter bits or high-resistance fasteners.\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 in the PSR 14.4 LI\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PSR 14.4's motor draws a sharp inrush current spike the instant the trigger is pulled — this can be three to five times the steady running current. A new replacement pack fresh from storage may have its BMS overcurrent threshold set conservatively until it completes a full cycle. If the tool cuts out immediately on trigger pull and recovers after a second attempt, the BMS is tripping on that inrush spike. Run one full charge-discharge cycle and the threshold recalibrates to the actual motor load profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger showing no charge light on a new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs in storage self-discharge slowly. If cell voltage drops below approximately 2.5V per cell, many chargers — including the Bosch AL 1404 — will refuse to start a charge cycle as a safety measure. The symptom is no indicator light at all, or a fast blinking red. Place the pack on the charger, remove it after 30 seconds, and re-seat it firmly. If the charger still won't engage, the pack needs a pre-charge pulse — some AL 1404 units initiate this automatically on the third insertion. If voltage is confirmed above 2.5V per cell with a multimeter but the charger still rejects the pack, check the rail contacts on both the pack and charger for oxidation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416075436122,"sku":"BWCS-BST206PW-1","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416075468890,"sku":"BWCS-BST206PW-2","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416075501658,"sku":"BWCS-BST206PW-3","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST206PW-1.webp?v=1779760116","url":"https:\/\/batteryweb.com\/products\/bosch-psr-144-li-replacement-battery-144v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
