It fits Ridgid cordless drills, impact drivers, and handheld power tools across the 130383001, 130383025, 130383028, and R840084 model range. Voltage and connector match OEM — the tool's charger and BMS handshake as they would with the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e130383001 series compatibility:\u003c\/strong\u003e\n    These models share the same 18V rail, slide-mount connector format, and BMS communication protocol. A replacement pack at the correct voltage and cell configuration slots into the same charge and discharge cycle without modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on an 18V Ridgid platform and monitored the BMS response across low, medium, and high draw events. Cell balancing held across all cycles and overcurrent protection triggered correctly at threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush break-in:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque applications. This lets the BMS log motor inrush current draw and calibrate its overcurrent thresholds before it sees a hard start spike from a drill bit under load.\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 18V motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a Ridgid drill under load, the motor draws a current spike in the first few milliseconds that can be several times the running draw. If the BMS has not profiled the tool's inrush signature — or if cell voltage is already low — it reads that spike as an overcurrent fault and cuts the output. This is a protection event, not a cell failure. To clear it, release the trigger fully, wait three seconds, and restart at low speed. If it trips repeatedly, check that the terminal contacts on the battery dock are clean and seated flush, since elevated contact resistance pushes the apparent draw higher than the actual motor load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising a new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage, and if the pack drops below approximately 2.5V per cell, most 18V chargers will not initiate a charge cycle — the charger reads the low voltage as a damaged or unsafe pack. This is common with new replacement batteries that have been warehouse-stored for several months. Some Ridgid chargers have a recovery or trickle mode — leave the pack seated for 10–15 minutes before removing it, as the charger may pulse a small current to lift the cells above the acceptance threshold. If the charger still rejects the pack, check that the cell voltage at the terminal is above 14V total before assuming the pack is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416050565210,"sku":"BWCS-RDD840PX-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416050597978,"sku":"BWCS-RDD840PX-2","price":102.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416050630746,"sku":"BWCS-RDD840PX-3","price":113.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RDD840PX-1.webp?v=1779759860","url":"https:\/\/batteryweb.com\/products\/ridgid-130383001-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
