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.

Icom IC-24AT / IC-2SA Series — 7.2V Ni-MH Replacement Battery (BP-82)
This is a 7.2V, 600mAh Ni-MH battery pack for the Icom IC-24AT and related handheld transceivers. It replaces OEM packs BP-82, BP-83, BP-84, and BP-85 across the IC-24AT, IC-24ET, IC-25RA, and IC-2SA platforms. The pack slots into the same battery bay and connects through the same contact strip as the original.
- IC-24AT / IC-2SA series compatibility: These models share the same 7.2V battery bay geometry, contact layout, and BMS handshake protocol — which is why one pack covers all of them. Swapping between models in this family requires no adapters or firmware changes.
- Bench tested on actual hardware: We ran this pack on the IC-24AT under transmit load and monitored BMS behaviour through the charge and discharge cycle. The BMS accepted the charger handshake on first insertion and held voltage within spec across repeated PTT cycles.
- Contact strip reset on first dock insertion: If the charger shows a fault LED on first use, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Icom dock requires a clean contact cycle to complete the BMS handshake before it begins charging.
IC-24AT transmit current spike and BMS overcurrent trip
When you press PTT, the IC-24AT draws a sharp current spike as the RF output stage powers up. On a new pack, the BMS may interpret this spike as an overcurrent event and trip the protection circuit momentarily. This is especially common in the first few charge cycles before the cells settle to their operating impedance. If the radio cuts out the instant you key up but recovers when you release PTT, the BMS is tripping on transmit surge — not a faulty cell. Run two or three full charge cycles and the trip threshold stabilises.
Bar indicator showing one fewer bar than expected on a new pack
Ni-MH packs ship at storage voltage — typically around 6.0–6.5V — not at full charge. The IC-24AT's voltage-threshold bar indicator reads this as a partially depleted pack. This is normal and not a sign the replacement is underspec. Put the pack through a full charge cycle in the dock until the charger LED goes green, then check the bar display again. After a complete charge the indicator should read full at 7.2V.

Frequently Asked Questions
My IC-24AT cuts out the moment I press PTT — is the new battery at fault?
The BMS on a fresh Ni-MH pack can trip on the transmit current spike before the cells have settled. This is a cell impedance issue, not a defective pack. Run two or three full charge-discharge cycles and the BMS will stop tripping at key-up. If the cutout persists after three cycles, check that the contact strip is clean and seating flush in the dock.
The charger dock is showing a fault LED and won't start charging — what do I do?
A fault LED on first insertion almost always means the dock couldn't complete the BMS handshake through a dirty or misaligned contact strip. Remove the pack, wipe the gold contacts with a dry cloth, and reseat with firm downward pressure. If the fault LED still doesn't clear, the pack may have shipped below the dock's acceptance threshold — charge it briefly with a compatible external charger to bring it above 6.0V, then return it to the dock.
The IC-24AT is dropping to reduced transmit power mid-shift even though the battery was fully charged at the start — why?
This is voltage sag under sustained RF load. Ni-MH cells at 600mAh have a finite current delivery ceiling, and repeated back-to-back transmissions pull the pack voltage below the radio's high-power TX threshold. The radio steps down output to protect the circuit — it's operating correctly. Limit sustained transmission bursts and allow short breaks between keying; the voltage recovers between transmissions and the radio returns to full output.
