BP-209 Icom IC-A6 Replacement Battery 7.2V 1800mAh Ni-MH

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Icom IC-A6, IC-A24, and 31 other aviation transceiver models; replaces BP-209, BP-210, BP-222 and their N-suffix variants.
7.2V, 1800mAh nickel-metal hydride chemistry delivers sustained transmit power during extended airborne operations without mid-flight voltage sag.
Slide connector seats vertically into the radio battery slot with a single-pin alignment post; locking tab clicks flush against the IC-A6 chassis.
We bench-tested this cell on an IC-A6 charger dock; the NiMH BMS accepted voltage immediately with no fault LED, full charge cycle completed in six hours.
On first insertion into the Icom charger dock, if the fault light appears, remove the battery, wipe the gold connector pin with a dry cloth, and reseat firmly — the Icom platform requires a clean contact cycle before accepting a new cell.

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 — 7.2V Ni-MH Replacement Battery (BP-209)

This is a 7.2V, 1800mAh nickel-metal hydride replacement battery for the Icom IC-A6, IC-A6E, IC-A24, IC-A24E, and over 31 additional Icom handheld aviation transceiver models. It replaces OEM part numbers BP-209, BP-209N, BP-210, BP-210N, BP-222, and BP-222N. The physical dimensions are 120.60 × 54.00 × 36.35mm — check yours before ordering if you are unsure which pack your radio uses.

  • IC-A6 and IC-A24 platform fit: These models share the same battery bay geometry, contact rail spacing, and BMS handshake protocol. A single pack covers the full series because Icom standardised the connector and voltage rail across the IC-A aviation line when it moved from the original BP-209 to the BP-209N revision.
  • Bench tested on actual hardware: We ran this pack through charge and transmit cycles on the IC-A6 platform. The BMS accepted the dock charge without a fault condition, and the transmit current spike on PTT did not trip the overcurrent threshold.
  • First insertion into the charger dock: If the dock LED blinks fault on the first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom aviation charger requires a clean contact cycle to complete the BMS handshake before it will begin the charge sequence.

Why the IC-A6 drops to reduced TX power mid-session on a new battery

Ni-MH cells ship at storage voltage — typically 1.1–1.2V per cell — not full charge. The IC-A6 monitors pack voltage under transmit load and steps down RF output when it sees sustained sag below its threshold. This is not a fault with the replacement pack; it is the radio protecting its PA stage. Run a full charge cycle first, then allow the cells to reach operating temperature before extended use in cold cockpit environments.

Bar indicator showing one fewer bar than expected after fitting a new pack

The IC-A6 and IC-A24 use a voltage-threshold bar indicator, not a fuel gauge chip. A new Ni-MH pack at storage voltage will read one or two bars below full even though the cells are not depleted. Charge the pack fully in the Icom dock until the LED goes solid green. After a complete charge, the bar display will read accurately against actual cell voltage.

Frequently Asked Questions

My IC-A6 cuts out completely when I press PTT on a brand-new pack — what's happening?

The transmit current spike on PTT can trip the BMS overcurrent threshold if the pack cells are still at storage voltage and internal impedance is elevated. This is not a failed battery. Charge the pack fully before transmitting — a partial charge leaves cell impedance high enough that the sudden RF draw looks like a fault condition to the BMS. After a full charge cycle, PTT should key normally without cutout.

The Icom charger dock LED keeps blinking and never switches to a solid charge light — how do I clear it?

A blinking fault LED usually means the dock could not complete the BMS handshake on first contact. Remove the pack, wipe the gold contact strip on both the battery and the dock with a dry cloth, and reseat the pack with firm downward pressure until it clicks. If the LED still blinks, the pack voltage may be below the dock's acceptance threshold after extended storage — leave it seated for 10–15 minutes and the dock will typically recover the pack once it detects a minimum cell response voltage.

The IC-A24 was in storage for several months and now the replacement pack won't charge at all — is it dead?

Ni-MH packs can drop below the charger's minimum acceptance voltage during extended storage, causing the dock to refuse the charge cycle entirely. This is a BMS lockout, not a dead cell. Try seating the pack in the dock for 20–30 minutes without removing it — many Icom chargers will trickle a recovery current once they detect even a minimal voltage response. If the dock accepts the trickle, the pack will climb back above the acceptance threshold and switch to normal charge. Target a full charge before the first transmit session.
