Icom IC-7300 & IC-9700 RTC Battery Modification Upgrade

Stop resetting your clock — fix it properly

If you own an Icom IC-7300 or IC-9700, you may already be familiar with a common annoyance — the internal clock resetting every time the radio is powered down.

This happens because the original internal backup battery (soldered directly to the PCB) eventually goes flat. Once depleted, the radio can no longer retain time and date settings when switched off.

The Solution

Our professional RTC battery modification permanently resolves this issue by:

  • Removing the original soldered backup battery

  • Installing a CR2032 coin cell battery holder (yes — standard, widely available 2032 battery)

  • Allowing future battery replacement by the end user

Once completed, replacing the battery is simple:

➡️ Remove the radio cover
➡️ Pop out the old CR2032 battery
➡️ Insert a new one

No soldering. No specialist tools. No repeat workshop visits.

Key Benefits

  • ✔ Eliminates clock reset issues

  • ✔ Uses standard CR2032 coin cell battery

  • ✔ Future battery changes are quick and user-friendly

  • ✔ Professionally installed by ML&S workshop technicians

  • ✔ Extends the long-term usability of your radio

Why This Matters

Without this modification, the only way to replace the original battery is to:

  • Open the radio

  • Desolder the old battery

  • Solder in a new one

For most users, this is impractical — meaning many simply live with an incorrect clock.

This upgrade turns a one-time inconvenience into a permanent fix.
