It fits the full ONE+ platform — drills, circular saws, impact drivers, and 120+ other models sharing the same slide-pack form factor. Voltage is 18V nominal; capacity is 3000mAh (54Wh) as supplied.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eONE+ platform compatibility:\u003c\/strong\u003e\n    Every tool in the Ryobi ONE+ 18V range uses the same slide-rail connector and expects the same 18V BMS handshake. That shared architecture is why a single pack — part number BPL1815 — covers drills, saws, sanders, and more without modification.\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 BID-1801M drill and a circular saw. The BMS responded correctly to motor-start inrush, held voltage under sustained load, and tripped at the expected overcurrent threshold before recovering cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor break-in on first use:\u003c\/strong\u003e\n    Run the tool at half load for two cycles before full-torque applications. This lets the BMS profile the motor's inrush current draw and set overcurrent thresholds accurately before you hit peak demand.\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 drill and saw motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a saw or drill, the motor draws a spike of current before it reaches running speed. On an 18V Li-ion pack, this inrush can briefly exceed the BMS overcurrent threshold — especially if the pack is cold or the cells have never been profiled against that specific motor. The BMS reads the spike as a fault and cuts output to protect the cells. A fresh pack that hasn't completed a full break-in cycle is more likely to trip here than one that has seen two or three full charge\/discharge cycles on the same tool.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger won't recognise the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells stored for several months can drop below the charger's acceptance voltage — typically around 2.5V per cell. When that happens, the Ryobi charger sees a voltage outside its expected window and refuses to begin a charge cycle, often showing a blinking or solid fault light. To recover the pack, leave it on the charger for 15–20 minutes — many chargers include a low-voltage recovery mode that trickle-charges the cells back above the acceptance threshold before switching to normal CC\/CV charging. If the charger still shows a fault after 20 minutes, check cell voltage with a multimeter; any cell reading below 2.0V has likely suffered permanent capacity loss.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416029888602,"sku":"BWCS-RTB815PW-1","price":105.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416029921370,"sku":"BWCS-RTB815PW-2","price":124.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416029954138,"sku":"BWCS-RTB815PW-3","price":137.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RTB815PW-1.webp?v=1779759627","url":"https:\/\/batteryweb.com\/products\/ryobi-one-18-volt-cordless-tools-replacement-battery-18v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
