Sanyo Eneloop Rechargeable Batteries
I go through batteries at a fairly high rate. Electronic devices for the wilderness, such as my headlamp and GPS, see regular use. At home, things like my wireless mouse need power. The biggest drain are my lights — particular in the winter, when they are used to light my regular commute.
This last spring I decided to invest in a set of rechargeable batteries. Although some of my devices run on CR123 batteries, most use AA or AAAs. To start with, I was concerned only with being able to recharge the AA and AAA batteries. Years ago I had a set of rechargeable batteries, but I think the technology was not very developed back then. They seemed to drain quickly and not hold many charges. Today, the market is different. Some brief research showed that there were many options out there, with positive reviews for most of them.
What most reviews seemed to suggest was that the majority of the offerings were all of equal quality, with most differences unlikely to be noticed outside of a laboratory. The most popular, though, seemed to be the Sanyo Eneloop and Maha Powerex batteries. I found some claims that, between the two, the Eneloops held a charge longer while on the shelf.
