New arrival
From $61.99 USD $75.99
Shipping calculated at checkout.
Fits Icom IC-V86, IC-V80, IC-T70A, IC-T70E and replaces OEM battery BP-298.
7.4V lithium-ion at 2600mAh delivers 19.24Wh capacity for sustained VHF field operations.
Connector slides straight down into the radio's battery slot with a single locking tab.
We bench-tested the BMS under sustained PTT cycles — no overcurrent lockout, stable voltage delivery.
On first charge in an Icom dock, remove and reseat the battery once if the fault LED appears — the contact cycle lets the BMS handshake complete before charging begins.

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,
Michael

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-V86 / IC-T70A Series — 7.4V Li-ion Replacement Battery (BP-298)

The BP-298 is a 7.4V, 2600mAh lithium-ion battery for the Icom IC-V86, IC-V80, IC-T70A, and IC-T70E handheld transceivers. These are VHF and dual-band portables used across commercial, professional, and amateur radio operations. It slots into the same battery bay and uses the same connector as the original Icom pack.

  • IC-V86 / IC-V80 / IC-T70 platform fit: All four models share the same 7.4V two-cell Li-ion architecture, battery bay footprint, and BMS handshake protocol — one pack covers the full series without modification.
  • Bench tested on actual hardware: We ran this pack through charge and transmit cycles on the IC-V86. The BMS handled PTT-triggered current spikes without tripping, and the charger dock accepted the pack cleanly on first insertion.
  • First insertion on 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 platform requires a clean contact cycle to complete the BMS handshake before charging begins.

Why the IC-V86 cuts out mid-transmission on a freshly inserted BP-298

A new cell ships at storage voltage — typically 3.6–3.7V per cell, not the 4.2V full-charge peak. When you key up on a fresh, uncharged pack, the transmit current draw can pull cell voltage below the BMS undervoltage threshold instantly. The BMS reads this as a fault condition and cuts output to protect the cells. The fix is straightforward: charge the BP-298 fully before the first transmission. Once both cells are at or near 4.2V, the voltage headroom under TX load is sufficient and the BMS stays open.

Bar indicator showing one fewer bar than expected after a full charge

The IC-V86 reads battery level from a simple voltage-threshold lookup — there is no fuel gauge chip involved. A new BP-298 may sit at 4.15–4.18V per cell after a first charge cycle rather than the full 4.2V, which can land just under the top bar threshold. This is not a fault with the pack. Run one full charge-and-transmit cycle to let the cells settle, then recharge to capacity. The bar indicator should align correctly once the cells have been through a real load cycle and the charger has topped them to their rated ceiling.

Frequently Asked Questions

The radio drops to low transmit power mid-shift even though the battery was fully charged at the start — what's happening?

This is voltage sag under sustained RF output. During extended transmit cycles, cell voltage dips under load; if it crosses the radio's reduced-power threshold, the IC-V86 steps down TX output automatically to stay within safe operating voltage. It is not a BMS fault — it is the radio protecting itself. If the BP-298 is new and this happens early in a shift, check that the dock completed a full charge cycle and that the charge indicator went green before you pulled the pack.

The charger dock blinks a fault LED and never starts charging — I've reseated the pack three times.

If the pack has been sitting unused for an extended period, cell voltage may have dropped below the dock's acceptance threshold — typically under 2.5V per cell. The Icom charger will not begin a charge cycle on a pack it cannot identify as safe. Remove the pack, wipe the gold contact strip clean with a dry cloth, and reseat slowly until you feel the latch click. If the fault LED persists, the cells may need a recovery charge — some third-party chargers have a recovery or boost mode that will bring the pack back above the 2.5V floor and allow normal charging to resume.

After a few months of light use, the BP-298 seems to run flat much faster than it did initially — is this premature capacity fade?

Shallow, frequent partial charges accelerate capacity fade in Li-ion cells. If the IC-V86 is used for short bursts and recharged after every brief session, the cells cycle through a narrow voltage band repeatedly rather than completing full charge-discharge cycles. This degrades usable capacity faster than normal field use would. To slow further fade, run the pack down to one bar on the radio's indicator before recharging, then charge fully — this keeps the cells exercising their full voltage range.
