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.

Black & Decker HP14KD / CD14CA Series — 14.4V Ni-MH Replacement Battery (A9262)
This is a 14.4V Ni-MH replacement battery pack rated at 2100mAh (30.24Wh) for Black & Decker cordless drill-drivers. It fits the HP14KD, CD14CA, CD14CAB, CD14CB, and over 160 additional 14.4V Black & Decker tools that share the same slide-in battery platform. Replaces OEM part numbers including A9262, A9276, PS140, HPB14, BD1444L, and A14, among others.
- HP14KD and CD14CA platform compatibility: These models share a common 14.4V slide-in connector and BMS handshake protocol. The battery's cell configuration and terminal layout match the OEM spec, so the charger recognition circuit reads the pack correctly without manual intervention.
- Bench tested on actual hardware: We ran this pack on an HP14KD under repeated trigger-pull cycles and sustained fastening loads. The BMS held overcurrent protection thresholds stable across motor-start inrush spikes, and cell temperature stayed within the pack's thermal limits under continuous use.
- Motor inrush break-in: On first use, run the drill at half load — light drilling or driving — for two full charge-discharge cycles before applying maximum torque. This lets the BMS profile the motor's inrush current draw and set accurate overcurrent thresholds before you push the pack hard.
BMS cutoff on trigger-pull inrush surge in 14.4V drill-drivers
When you pull the trigger on a cordless drill, the motor draws a short burst of current — often three to five times the running current — before it reaches speed. A Ni-MH BMS set conservatively will interpret that spike as a fault and cut power. This pack's overcurrent threshold is calibrated to the HP14KD motor profile, so the BMS distinguishes a normal inrush event from a genuine short. If you do see a cutout on trigger pull, the cells are likely under-charged — bring the pack to full charge before the next use.
Tool bogs under load and feels underpowered mid-task
Voltage sag under load is a separate failure from a hard cutout. The drill spins but loses torque, and the motor sounds strained. The most common cause is high resistance at the battery rail contacts — corrosion or debris on the slide-in terminals reduces the current the tool can actually pull. Clean the battery contacts and the tool's terminal rails with isopropyl alcohol, then recheck. If sag persists after cleaning, measure the battery voltage under load — a healthy 14.4V Ni-MH pack should hold above 12.5V during normal drilling.

Frequently Asked Questions
My charger blinks red when I put this new battery on — it won't start charging at all. What's wrong?
A Ni-MH pack that has sat in storage can drop below the charger's acceptance voltage threshold, which triggers the fault blink instead of a charge cycle. Some Black & Decker chargers reject packs below roughly 1V per cell across the string. Jump-start the pack by briefly connecting it to a known-good charger set to trickle mode, or swap it onto a compatible charger that has a recovery or conditioning mode. Once the pack climbs above the acceptance floor — typically around 10.8V for a 14.4V Ni-MH — the primary charger should recognise it and begin a normal charge.
The drill cuts out the instant I apply torque to a tight screw — trigger barely pulled. What causes that?
That's a BMS overcurrent trip triggered by motor-start inrush current, not a faulty battery. When the motor stalls against resistance, the current spike can exceed the BMS protection threshold and the pack disconnects to protect the cells. On Ni-MH packs this is more pronounced when the cells aren't fully charged — a partially charged pack has higher internal resistance, which amplifies the voltage drop on inrush. Charge the pack fully before use and run two lighter-duty break-in cycles; the BMS will calibrate to the motor's inrush profile and the cutouts should stop.
The drill ran fine for a few months but now the battery drains noticeably faster than it used to. Nothing else changed.
Capacity fade in Ni-MH cells is almost always caused by repeated shallow cycling — topping up the pack after light use instead of running it down properly. Shallow cycling leaves the cells in a partial-charge state and accelerates voltage depression. Run the pack down to the point where the tool noticeably slows, then charge it fully — do this three times in a row. This deep-cycle reconditioning doesn't fully reverse cell degradation, but it restores usable capacity by working the cells through their full electrochemical range. If capacity doesn't recover after three cycles, the cells have reached end of service life.
