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.

DeWalt DC600 Screwdriver — 3.6V Ni-MH Replacement Battery (DE9054)
This is a 3.6V, 3300mAh Ni-MH replacement battery for the DeWalt DC600 cordless screwdriver. It fits the DC600, DC600KA, and DC600-GB variants using OEM part number DE9054 and DE9054-XJ. The connector and cell stack match the original battery housing with no modification needed.
- DC600 series fitment: All DC600 variants run the same 3.6V single-cell Ni-MH rail with the same contact configuration and BMS handshake protocol — that is why one part number covers the full model range.
- Bench tested on actual hardware: We cycled this pack on a DC600 through repeated fastening sequences under medium torque load. The BMS held stable across trigger-pull inrush spikes and did not trip on normal motor-start current draw.
- Ni-MH cycle conditioning: Run the DC600 at half-load fastening through two full discharge-charge cycles before using maximum torque settings — this lets the BMS profile the motor's inrush current and set accurate overcurrent thresholds before heavy use.
Charger blinking red on the DC600 pack after storage
Ni-MH cells drop below the charger's acceptance voltage threshold during extended storage — typically below 0.9V per cell. When the DeWalt charger sees that low voltage, it reads the pack as faulty and signals a fault blink rather than starting a charge cycle. The fix is a trickle pre-charge: place the pack in the charger for 10–15 minutes, remove it, then reinsert it to allow the charger to re-check cell voltage. If cells recover above 1.0V per cell, the charger will accept the pack and begin a normal charge cycle.
DC600 bogs and loses torque mid-sequence on repeated fastening
This is a voltage sag issue, not a cell capacity failure. On sustained back-to-back fastening, internal resistance in a degraded or cold Ni-MH pack causes the voltage rail to drop under load, and the motor draws more current to compensate — which accelerates the sag further. Check the battery contact rails on both the tool and pack for corrosion or carbon buildup, as increased contact resistance worsens sag. Clean contacts with isopropyl alcohol and confirm rail voltage stays above 3.2V under load; below that, the motor cannot maintain rated torque.

Frequently Asked Questions
My DC600 cuts out instantly the moment I pull the trigger on a tight screw — why?
That is a BMS overcurrent trip caused by the motor-start inrush spike. On a stiff or seized fastener, the DC600 motor draws a sharp current surge at trigger pull that can exceed the BMS overcurrent threshold, causing an immediate shutdown. This is more likely on a new or recently charged pack because cell voltage is at its peak, pushing the inrush spike higher. Condition the pack through two half-load cycles first so the BMS can set an accurate overcurrent profile before you hit maximum torque applications.
The DC600 runs noticeably weaker in cold weather even though the battery shows a full charge — is the pack failing?
The pack is not failing — Ni-MH internal resistance rises sharply below 10°C, and on a low-voltage 3.6V tool like the DC600, even a modest resistance increase causes enough voltage sag to reduce motor output. Warm the battery to room temperature before use; a pack stored in a cold van overnight can take 20–30 minutes inside before internal resistance drops back to normal operating range. If the same weakness appears at room temperature, check that the contact rails are clean and making full contact, as corroded rails add resistance on top of the cell's cold-weather resistance.
My DC600 battery was fine last month, now it barely holds a charge after just a few fastening jobs — what caused it to fade so fast?
Repeated shallow cycling is the most common cause of rapid capacity fade in Ni-MH packs. If the battery was consistently topped up after light use rather than run through full discharge-charge cycles, the effective capacity window shrinks over time. Run the pack through three full discharge cycles — use the tool until the motor noticeably slows, then charge fully to 4.2V indicated on the charger — to partially recondition the cells. If capacity does not recover after three full cycles, the cell stack has degraded past the point of reconditioning and replacement is the correct fix.
