I swapped all my AA and AAA batteries for Enelooops. The cheaper white ones are the best for most applications.

I'm frustrated by the error rate on my Eneloops over the years. I have dozens of them and I swear every other time I recharge them, one more starts blinking and refuses to recharge.

Also I would recommend switching to the IKEA rechargeable batteries which are supposedly the same thing except cheaper.
