DeWalt DC9180 18V Li-ion Replacement Battery 3000mAh

Up to 19% off
New arrival
From $81.99 USD $100.99
Shipping calculated at checkout.
Fits DeWalt DCD925, DCD925N, DCD925B2, DCD925KA — replaces DC9180, DC9180C, DC9182 battery packs.
18V Li-ion at 3000mAh delivers sustained torque on fastening and drilling without voltage sag during mid-load operation.
Slide connector seats into the DCD925 battery slot with a single locking tab on the left side — orientation is keyed.
We bench tested this cell on a DCD925 motor load and confirmed the BMS accepts inrush current without cutoff at full trigger pull.
On first use with the DCD925, run at half throttle for two cycles before maximum torque — lets the BMS profile motor inrush before locking overcurrent thresholds.

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

DeWalt DCD925 Series — 18V Li-ion Replacement Battery (DC9180)

This is an 18V Li-ion battery rated at 3000mAh (54Wh), built to fit the DeWalt DCD925, DCD925N, DCD925B2, and DCD925KA compact drill/drivers. It uses OEM-referenced part numbers DC9180, DC9180C, and DC9182. The connector and BMS handshake match the original DeWalt 18V slide-pack platform.

  • DCD925 platform fit: All four DCD925 variants share the same 18V slide-rail connector and BMS communication protocol. The battery slides into the same locking channel and the tool's onboard electronics read charge state identically to the original pack.
  • Bench tested on actual hardware: We cycled this pack under simulated drill load on the DCD925 platform. The BMS held stable across repeated trigger-pull inrush events, and cell balancing engaged correctly at full charge on the DeWalt 18V charger.
  • Break-in load cycling: On first use, run the drill at half-torque for two full discharge-and-charge cycles before driving at maximum clutch settings. This allows the BMS to log the motor's inrush current signature and set overcurrent thresholds accurately before heavy fastening work.

BMS overcurrent trip on trigger-pull inrush with the DCD925

The DCD925 motor draws a short inrush spike the instant the trigger is pulled — this can be three to five times the steady-state current draw. A new Li-ion pack fresh from storage has not yet profiled this spike. If the BMS treats it as a fault, it cuts the output rail immediately. Running two half-load break-in cycles teaches the BMS the motor's actual inrush signature and stops false overcurrent trips during normal drilling.

Charger flashing red on the DC9180 pack after extended storage

The DeWalt 18V charger has a minimum acceptance voltage — if a stored pack has self-discharged below roughly 12V on the 18V rail, the charger enters fault mode and blinks red rather than starting a charge cycle. Remove the pack, wait 60 seconds, and reinsert it to prompt a re-check. If the charger still refuses to start, a brief trickle charge using a compatible lab supply at 0.1A to bring cell voltage above 13V will bring the pack back into the charger's acceptance window.

Frequently Asked Questions

My DCD925 cuts out the instant I pull the trigger on a stubborn screw — battery seems fine otherwise. What's happening?

That's a BMS overcurrent trip caused by motor-start inrush current spiking above the pack's protection threshold. It's most common on a new or recently stored battery that hasn't profiled the DCD925 motor's inrush signature yet. Run two full cycles at low torque settings first — drill into soft timber at clutch setting 3 or 4 — before moving to heavy fastening. After those cycles, the BMS resets its overcurrent threshold around the actual inrush curve and the cut-outs stop.

The drill feels weak and bogs badly under load even with a charged battery — charger shows full but torque is clearly down. What's wrong?

That's voltage sag — under load, the battery's rail voltage drops further than it should, and the tool's motor can't maintain torque. Check the slide-rail contacts on both the battery and the DCD925 for oxidation or debris first, since contact resistance multiplies sag at high current. If the contacts are clean, the issue is capacity fade from repeated shallow cycling — frequently topping up the pack from 70–80% without completing full cycles accelerates this. Run two full discharge-to-charge cycles and re-test; if the sag persists, the cell capacity is genuinely degraded.

I left my DCD925 battery unused in the garage over winter and the charger won't start — just blinks red. Is it dead?

Not necessarily. Cold storage plus self-discharge can drop cell voltage below the DeWalt charger's minimum acceptance threshold, so it flags a fault instead of starting a charge cycle. Pull the pack out, leave it at room temperature for at least an hour, then reinsert it — the charger re-checks voltage on each insertion. If it still won't accept the pack, use a compatible charger or lab supply to trickle charge at 0.1A until the pack reaches 13V, then return it to the DeWalt charger to complete the full charge cycle normally.
