That charger does do it fast, it's never took the 2 hours it states on the charger to do the job. But sometimes, the batteries gets quite hot while charging, in fact, too hot to hold afterwards.
I'll probably buy some more soon, because my keyboard batteries will go at some point. I doubt that they'll last the 3 years that's claimed. Mabye with light use, but I use mine a lot, and don't even turn it off afterwards. These type of batteries will probably do well with keyboards, too.
I like Radio Shack's selection of batteries, they have one for most anything, even older home/cell phones where the batteries are unavailable elsewhere. Usually after 2-3 years, the OEM's of phones don't carry them any longer. Today, most users are ready to upgrade to a new one by that time.
But me, if what I have works for my purposes, I keep it as long as possible. This is the cell phone that I still use.

None of that fancy bluetooth and very limited internet features, but I'm not paying for a high priced cell plan for that tiny computer that I can hardly see. As long as I can find batteries for it, I'll use it.
BTW, I did buy a 'overstock' OEM battery for it a couple of years ago, but the Radio Shack ones are better. They're fresher, and holds a charge longer. That OEM battery didn't last a year.
I'll ask about one of those slower chargers.
