It replaces OEM part numbers 2 607 335 040, 2 607 336 039, 1 600 Z00 000, and related cross-references. The battery slots into the same slide-rail pack interface and communicates with the tool's BMS over the same signal line as the original.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePSR 18 LI-2 and PSB 18 LI-2 compatibility:\u003c\/strong\u003e\n    These models share an identical 18V slide-rail connector format and the same BMS handshake protocol. One battery works across the full drilling, screw-driving, and sanding variants without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start inrush events on a PSR 18 LI-2. The BMS held the overcurrent threshold correctly and did not trip during normal trigger pulls at full torque.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on the PSR 18 LI-2:\u003c\/strong\u003e\n    On first use, run the drill at half load — light drilling, no high-torque fastening — for two full discharge and charge cycles. This lets the BMS log the motor's inrush current profile before it locks in overcurrent trip thresholds.\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 surge in the PSR 18 LI-2\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless drill, the motor draws a brief current spike — often three to five times the running current — before the armature reaches speed. A new or storage-depleted pack can have slightly elevated internal resistance, which amplifies the voltage drop at that spike. If the BMS reads the drop as an overcurrent fault, it cuts the output rail and the tool stops dead. Running two break-in cycles at half load lowers internal resistance and lets the BMS calibrate before it sees full motor-start demand.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red and won't accept the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored without periodic top-up can drop below the charger's acceptance threshold — typically around 2.5V per cell. The Bosch AL 1830 CV charger signals this state with a blinking red LED and refuses to begin the charge cycle. Connect the pack to a charger that supports a low-voltage recovery or \"wake-up\" pre-charge mode, or briefly connect a known-good pack in parallel for 60 seconds to raise the cell voltage above 2.8V per cell. Once above threshold, the standard charger will accept it and resume the normal charge sequence.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416057086042,"sku":"BWCS-BST182PW-1","price":97.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416057118810,"sku":"BWCS-BST182PW-2","price":114.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416057151578,"sku":"BWCS-BST182PW-3","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST182PW-1.webp?v=1779759807","url":"https:\/\/batteryweb.com\/products\/bosch-psr-18-li-2-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
