I bought about 20 AA batteries for our office at work, and they paid for themselves in about 2 months. I bought a charger that will charge 8 batteries at one time and will deep cycle / refresh them. I set up a box that users drop their old batteries into. When I get enough I charge them and put the charged batteries in another container. It is obvious which ones are charged and which aren't. With all the wireless keyboards, mice, remotes it really helps.
