It fits the BID-1801M, BID-180L, BID1821, JSP-180QEOM, and over 100 additional Ryobi 18V Ni-MH platform tools. The pack slots into the original battery port and connects to the same charging system.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRyobi 18V Ni-MH platform fit:\u003c\/strong\u003e\n    All listed models share the same 18V Ni-MH voltage rail and slide-in connector format. The BMS handshake and thermistor pin-out match across the BPP-1817, BPP-1815, BPP-1820, and related part numbers in this cluster. One pack works across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a BID-1801M. The BMS held cutoff at the correct low-voltage threshold and the thermistor line communicated properly with the charger throughout.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in load for motor inrush profiling:\u003c\/strong\u003e\n    On first use, run the drill at half load for two cycles before applying maximum torque. This lets the BMS record the motor inrush current signature before locking overcurrent thresholds — reduces nuisance trips on aggressive fastening starts.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS overcurrent trip on trigger-pull inrush in the BID-1801M\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have lower internal resistance than older Ni-Cd packs, but the BID-1801M motor still pulls a sharp inrush spike the moment the trigger engages. If the BMS has not yet profiled that spike — common with a new or recently stored pack — it can read the surge as a fault and cut the output rail. The fix is two low-load break-in cycles before driving at full torque. After that, the BMS threshold adjusts and cold-start trips stop.\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\"\u003eNi-MH cells self-discharge during storage — if the pack has been sitting long enough, cell voltage drops below the charger's acceptance window and the unit refuses to begin a charge cycle. Pull the pack out, wait 60 seconds, and re-seat it firmly to reset the charger's detection circuit. If the charger still rejects it, the cells may need a manual trickle boost to bring them back above the 1.0V-per-cell acceptance floor before normal charging can begin. Most Ryobi 18V chargers accept the pack again once voltage is restored to approximately 14V across the full pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416073273434,"sku":"BWCS-RYB813PW-1","price":98.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416073306202,"sku":"BWCS-RYB813PW-2","price":115.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416073338970,"sku":"BWCS-RYB813PW-3","price":128.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RYB813PW-1.webp?v=1779760143","url":"https:\/\/batteryweb.com\/products\/ryobi-bid-1801m-replacement-battery-18v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
