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.

Radon 302 / 353 / 354 / 361 Series — 7.2V Ni-MH Replacement Battery

This is a 7.2V 2200mAh Ni-MH replacement battery for the Radon 302 two-way radio and compatible models in the 353, 354, and 361 series. It slots into the same battery bay and uses the same contact layout as the original pack. Capacity is rated at 2200mAh (15.84Wh) — matching the stock specification.

  • 302 / 353 / 354 / 361 compatibility: These models share the same 7.2V two-cell Ni-MH voltage rail and identical battery bay dimensions. The contact alignment and BMS handshake protocol are consistent across the series, so one pack covers all listed units without modification.
  • Bench tested on actual hardware: We cycled this pack through full charge and discharge on a 302-series body. The BMS accepted the charge sequence without interruption, and transmit-current draw stayed within the rated window across multiple PTT cycles.
  • First insertion into the charger dock: If the dock LED flashes fault on first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The Radon dock requires a clean contact cycle to complete its BMS handshake before charging begins.

Why the Radon 302 cuts out mid-transmission on a fresh pack

Ni-MH cells ship at storage voltage — typically 1.1–1.2V per cell, giving a pack voltage around 6.6–7.2V before conditioning. When you press PTT, the transmitter draws a short high-current spike. If the pack hasn't completed its first full charge cycle, that spike can pull cell voltage below the BMS cutoff threshold and trip a momentary disconnect. Run one full charge before the radio goes into active use. After the first complete cycle, the cells stabilise and the cutout behaviour stops.

Bar indicator reading one bar low on a fully charged pack

The Radon 302 uses a simple voltage-threshold bar display — each bar corresponds to a voltage window, not a percentage. A new Ni-MH pack that hasn't been conditioned sits at a resting voltage just below the top threshold, so the radio displays one fewer bar even after a full charge. This isn't a fault with the pack. Run one complete discharge-to-charge cycle and the resting voltage will settle into the correct top-bar window — typically above 8.0V open circuit.

Frequently Asked Questions

The Radon 302 drops to low transmit power partway through a shift — battery is fully charged at the start

This is voltage sag under sustained RF output, not a dead pack. Ni-MH cells can't sustain peak voltage during back-to-back transmissions — internal impedance rises as the cells warm up, pulling pack voltage below the radio's full-power threshold. The radio reduces TX output to protect the circuit. Let the pack cool for 10–15 minutes and check resting voltage — it should read above 7.5V. If it drops below 7.0V at rest after a partial shift, the cells are worn and the pack needs replacing.

The charger dock never clears its fault LED — pack is seated correctly and contacts look fine

A dock fault that never clears usually means the pack voltage is below the dock's acceptance threshold — typically below 6.0V on a Ni-MH 7.2V pack. This happens after extended storage when the cells have self-discharged past the recovery floor. Remove the pack, short-charge it for 10 minutes using a compatible trickle charger or a second dock that accepts low-voltage packs, then reseat it in the primary dock. If the pack recovers above 6.5V, the dock will accept it and begin the normal charge sequence.

Battery inserted correctly but the radio won't power on at all — dock just charged it green

A green dock light confirms the charger's voltage target was reached, but Ni-MH packs can show full charge voltage at the terminals while individual cells are imbalanced. If one cell has reversed polarity during a deep discharge, pack voltage collapses the moment the radio draws current and the BMS trips. Remove the pack, measure terminal voltage with a multimeter — a healthy 6-cell 7.2V Ni-MH pack should read between 7.8V and 8.4V after a full charge. If it reads below 7.0V immediately after charging, cell reversal has occurred and the pack should be replaced.
