I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

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.

Icom IC-A6 / IC-A24 Series — 7.4V Li-ion Replacement Battery (BP-209N / BP-210N / BP-222N)

This is a 7.4V 2200mAh lithium-ion replacement battery for Icom handheld aviation transceivers. It fits the IC-A6, IC-A6E, IC-A24, IC-A24E, and over 31 additional Icom models that share the BP-209, BP-210, BP-222, BP-209N, BP-210N, and BP-222N footprint. Capacity is 2200mAh (16.28Wh) — sourced from product data, not estimated.

  • IC-A6 and IC-A24 platform compatibility: These models share the same battery bay geometry, 7.4V voltage rail, and BMS handshake protocol. A single cell pack covers the full lineup because Icom standardised the connector and BMS communication across this aviation transceiver generation.
  • Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the IC-A6 platform. The BMS engaged cleanly at full transmit current draw, and the voltage held steady through repeated PTT keying without tripping overcurrent protection.
  • First insertion into the charger dock: If the dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom charger dock requires a clean contact cycle to accept the new BMS handshake before charging begins — this is not a faulty cell.

IC-A6 transmit current spike and BMS overcurrent cutoff

When you press PTT on an aviation transceiver, the transmit current draw jumps sharply — significantly higher than receive mode draw. A new replacement pack with a conservatively tuned BMS can interpret this spike as an overcurrent event and cut output for a fraction of a second. This is not a capacity problem; it is a BMS threshold calibration on first use. Running two or three full transmit cycles allows the BMS to log the radio's actual current signature and stop tripping on normal PTT events.

Bar indicator showing one fewer bar than expected on a new pack

New lithium-ion cells ship at storage voltage — typically around 3.7V per cell, not the 4.2V peak of a full charge. The IC-A6 bar indicator reads voltage thresholds directly; it does not track charge history. A pack sitting at storage voltage will show one or two bars even though the cell is healthy. Charge the pack fully in the dock before drawing any conclusion — once it reaches 8.4V across both cells, the bar indicator will read correctly.

Frequently Asked Questions

My IC-A6 cuts out completely for a split second every time I key up — is the new battery faulty?

This is a BMS overcurrent trip caused by the transmit current spike when PTT is pressed. The new pack's protection circuit sees the sharp current jump and briefly cuts output until it logs the radio's normal draw signature. Run five to ten full PTT cycles and the cutouts will stop. If they continue beyond that, check that the contact strip is clean and seated fully — poor contact increases apparent resistance and worsens voltage sag at the terminals.

The charger dock is blinking a fault LED and won't start charging the new BP-209N pack — what's wrong?

The Icom dock checks BMS contact continuity before it begins a charge cycle. If the gold contacts on the pack or the dock are not making clean contact, the dock flags a fault rather than start charging. Remove the pack, wipe the contact strip with a dry lint-free cloth, check the dock contacts for debris, and reseat the pack with firm downward pressure. If the fault LED clears within a few seconds of reseating, the charge cycle will begin normally — no further action needed.

After sitting unused in my flight bag for two months, the IC-A24 won't power on with the new battery — how do I recover it?

Lithium-ion cells in storage discharge slowly, and if the pack dropped below the BMS recovery threshold (typically around 6.0V for a 7.4V two-cell pack), the protection circuit locks out to prevent deep-discharge damage. Place the pack in the Icom charger dock for at least 15 minutes — most Icom docks include a trickle pre-charge stage that brings the cell voltage up to the recovery threshold before switching to full charge current. Once the dock shows a steady charge indicator, the BMS has cleared the lockout and the pack will charge and operate normally.
