WR120 Battery-Only Runtime Expectations

If you're using your Midland WR120 weather radio without the AC adapter, battery life will vary depending on the type of AA alkaline batteries you use and how you operate the radio.

🔋 Battery Runtime Estimates

Using basic or lower-cost AA alkaline batteries:

• Standby Mode (receiving alerts only): Up to 2 days
• Continuous NOAA Weather Broadcast (at full volume): Up to 12 hours

Using higher-quality or name-brand AA alkaline batteries:

• Standby Mode (receiving alerts only): Up to 3 days
• Continuous NOAA Weather Broadcast (at full volume): Up to 15.5 hours

🔍 Tip: For best performance and emergency readiness, we recommend using high-quality alkaline batteries and keeping your WR120 plugged in with the AC adapter when possible.
