• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I would say with a good set of Eneloop Pro rechargeable batteries and a good external charger, probably would get anywhere from 8 to 12 hours possibly more or less, depending how active the scanner is, and/or if using the.LCD light and the LED light.

For now I use alkaline batteries on my TRX-1 as I have a large supply and haven't got around to trying the rechargeable battery options. I set the settings to have the backlights for both the keyboard and display screen to be on all the time as I like the look but it seems to drain the batteries in just a few hours.

To save battery life I usually run the scanner off my laptop when on my desk and reserve the battery options for when the power goes out.

Battery life is going to be affected by many, many variables to include not only what type of batteries you use but also display and keypad back lighting (full time, part time, etc.), how much activity you are receiving, if it's analog or digital (I don't know this for sure but I suspect decoding digital takes more power), volume, and probably more drain for recording.

I had my TRX-1 running yesterday on a set of newer Eneloops and I was receiving almost no activity (I was monitoring for something specific that wasn't being heard much). The radio was still going strong after 10-11 hours but of course it wasn't doing much and as a result the back lights were almost never on.

I'm using 2 sets of PowerEX 2700. I change batteries once a day, usually in the afternoon. I'm typically running it 10-14 hours a day. I would say about 10-11 hours on one set of batteries. Scanning 260 conventional channels, 2 trunked systems, back light on low, no LED, all digital. I would say moderate traffic.

I have had 14 hours from fresh charge to the TRX-1 shutting down on it's own during my battery testing. I normally don't let it get that far under normal use.
