Battery Care Tips
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
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.

DeltaFox Grizzly 80001146 / 80001147 — 18V Li-ion Replacement Battery
This 18V 1500mAh (27Wh) Li-ion battery replaces the original pack on the Grizzly 80001146, 80001147, 2020, and 2040 cordless tools. It fits drills, impact drivers, and other compact 18V tools in the Grizzly lineup that share the same slide-in connector and voltage rail. Swap it in directly — no modifications needed.
- Grizzly 80001146, 80001147, 2020, 2040 compatibility: These four models run the same 18V rail and use an identical connector footprint with matching BMS handshake logic, which is why one cell pack covers all four without adapter hardware.
- Bench tested on actual hardware: We cycled this pack through motor-start inrush loads on a drill platform and confirmed the BMS handles trigger-pull current spikes without tripping into protection mode under normal use conditions.
- First-use load conditioning: 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 calibrate its overcurrent threshold before you push maximum demand.
BMS cutoff on motor-start inrush surge with Grizzly drills
When you pull the trigger hard on a Grizzly drill, the motor draws a short inrush spike — often three to five times the running current. A BMS that hasn't profiled that motor yet can read the spike as a fault and cut the cell output instantly. This is not a defective battery; it's a protection trip. Run two partial-load cycles first so the BMS logs the inrush pattern and widens the cutoff window accordingly. After that, full-torque trigger pulls should clear without interruption.
Charger blinking red and refusing to accept the new pack
Li-ion cells that have been stored for several months can drop below the charger's acceptance threshold — typically around 2.5V per cell. When the Grizzly charger sees a pack below that floor, it blinks red and refuses to start a charge cycle rather than risk pushing current into a potentially damaged cell. Leave the pack on the charger for 15–20 minutes anyway; most Grizzly chargers include a trickle pre-charge mode that will nudge cell voltage up to the acceptance threshold before switching to full charge. If the light stays red past 30 minutes, measure pack voltage across the terminals — anything below 10V on an 18V 4-cell pack means the cells need a manual recovery charge at 0.1C before normal charging can resume.

Frequently Asked Questions
My Grizzly drill cuts out the moment I pull the trigger hard — battery or tool fault?
That's a BMS overcurrent trip, not a faulty battery or tool. The motor-start inrush current spikes sharply on trigger pull, and a new or cold pack can read that as an overcurrent fault and shut off output immediately. Run two half-load cycles first — light drilling, no torque resistance — so the BMS can profile the inrush pattern before you demand full torque. After conditioning, the cutout on hard trigger pulls should stop.
The drill feels weak and bogs down mid-hole even though the battery shows charged — what's happening?
That's voltage sag under load, usually caused by high resistance at the battery contact rails. Check the slide-in connector terminals on both the battery and the tool for oxidation or debris — even a thin layer of corrosion adds enough resistance to drop the voltage rail during draw. Clean both contact surfaces with isopropyl alcohol and a firm brush. If the tool still bogs after cleaning, measure the pack voltage under load; a healthy 18V pack should hold above 16V during normal drilling.
The battery lost noticeable capacity after only a few months of light use — is that normal?
Repeated shallow cycling — consistently charging from 60–70% back to full rather than running the pack down further — accelerates capacity fade in Li-ion cells. The BMS recalibrates its state-of-charge estimate based on partial cycles, which also causes the gauge to read inaccurately over time. Run the pack down to the tool's low-voltage cutoff point (around 15V on an 18V pack) once every 10–15 cycles to let the BMS reset its full-cycle reference. That alone slows the apparent capacity drop significantly.
