Batteries

Hope this is the right place to ask ..........

I need some new rechargeable AA batteries, and I hear eneloops are the best.
I have several brands now that I use, and they are getting used up. I even
bought a car charger, as we go out to do real estate surveys, and having
batteries fail is a big deal. But it seems as though the ones we have are
not staying up as good as they once were.

So, before I spring for the cash, I'd like to hear about what to buy.

Help appreciated.
