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
