I'm looking to stock up ahead of Christmas on AA and AAA batteries. Usually I grab the cheapest at the supermarket or the packs at Ikea if I'm ever in there. I did a bit of googling earlier and read that there seem to be different types within certain brands, especially Duracell. I have 8 AA (Sanyo) Eneloops, although I have no idea which appliances they are in but occasionally 2 seem to pop up every now and then as they item they were powering run flat. I found 2 in my electric toothbrush this morning. Now I just need to find my charger. This website Battery Showdown — The Best AA Battery You Can Buy? gives a fair bit of info so I'm ordering some VARTA High Energy Alkalines. Anything I'm missing?
