It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

KINETIC MH330AAAK6HC — 7.2V Ni-MH Replacement Battery (MH330AAAK6HC)

This 7.2V, 300mAh Ni-MH battery replaces the original power cell in the KINETIC MH330AAAK6HC electronic dog training collar. It restores the voltage rail that drives both stimulation output and tone delivery. Capacity is 300mAh (2.16Wh) — matching OEM spec from the product data.

  • MH330AAAK6HC collar fit: This collar runs a fixed 7.2V Ni-MH cell stack. The BMS on the collar expects that specific voltage profile and cell chemistry for correct charge termination. Swapping to a different chemistry or voltage breaks that handshake and can trigger false full-charge signals.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the MH330AAAK6HC platform. The BMS accepted the charge curve without error flags, and stimulation output stayed within expected operating range across the full discharge cycle.
  • Post-swap collar reset: After fitting this battery, power the collar off completely, wait 10 seconds, then power back on before placing it on the dog. The collar's internal circuitry re-initialises stimulation level calibration on a fresh boot — skipping this step can cause inconsistent output levels on first use.

Why the MH330AAAK6HC collar shows full charge but cuts out during a training session

Ni-MH cells age by losing capacity, not by losing resting voltage. A worn cell can read 7.2V at rest but collapse under the current draw of a stimulation pulse. The collar's BMS sees the voltage drop as a fault and interrupts output. This is a cell-health failure, not a charger or receiver problem. Replacing the battery resolves it — the resting voltage on a fresh cell should hold above 7.0V under load.

Collar not responding to the transmitter after fitting a new battery

A full power interruption — such as a battery swap — clears the collar's active pairing state on some MH330AAAK6HC units. The collar needs to re-pair to the transmitter before it will accept commands. Power both the collar and transmitter off, then follow the pairing sequence in the manual starting from step one. Most units re-pair within 30 seconds and confirm with a beep or indicator light.

Frequently Asked Questions

I just put a new battery in my MH330AAAK6HC collar and the stimulation feels weaker than it used to — is something wrong?

This is usually a cell break-in issue with fresh Ni-MH batteries. Ni-MH cells don't always deliver full capacity on the very first cycle — output stabilises after one or two full charge-discharge cycles. Run the collar through a complete charge, use it until the low-battery indicator triggers, then charge it fully again. After that second cycle, stimulation output should return to normal operating level.

The MH330AAAK6HC battery is draining noticeably faster than it did with the original — what causes that?

Ni-MH cells are sensitive to incomplete charging. If the collar's charger was used with a depleted original cell for a long time, it may have developed a shortened charge routine timed to that cell's degraded state — but that's unlikely with a fresh battery swap. More commonly, the new cell needs a full first charge: plug in until the charger confirms completion, not just until the indicator changes colour. A full charge on a fresh 300mAh Ni-MH cell takes the charger's full rated cycle time.

My MH330AAAK6HC collar won't pair back to the transmitter after the battery swap — I've tried turning it on and off.

A simple power cycle won't always restore pairing on the MH330AAAK6HC after a battery interruption — the collar needs a full re-pair sequence, not just a restart. Power both the collar and the transmitter fully off, then hold the pairing button on the transmitter while powering the collar on, exactly as described in the pairing section of the manual. Don't attempt this indoors with other active transmitters nearby, as signal interference can prevent the handshake from completing.
