• 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:

a second charger is always a great idea. I also would not suggest leaving your powerex set on trickle for extended periods. Rather cycle them every so often, while keeping a fresh set at the ready.

NiMH batteries will discharge on their own (without anything connected to them), some more than others. They can lose up to 10% the first day, but lose less than 1% daily thereafter. Generally speaking, the higher the mA rating = the faster they will self-discharge.

As for the charger itself; If you're going to spend money on a stand-alone battery charger then I would suggest you buy a good quality charger, not some cheap "basic charger". ;)

The newest type of NiMH (package marked "pre-charged") batteries lose their charge much more slowly than the old type. Sanyo Enoloops are the most well known, but all the others seem to have them now. Walmart and Cosco have good prices.

If you're going to run NiMH batteries, they need to be used quickly. That's actually a step backward from NiCD's. Such is progress. You may be better off getting a couple of sets and use them full time instead of just for back up power. This guy usually has good deals... BATTERIES AMERICA
