Here’s a handy new device on sale at Amazon! From La Crosse Technology we have this new Alpha Charger for your batteries. One big annoyance of course is that batteries are a constant buy if you use a lot of gadgets for them and this device can solve that problem in a convenient (and safe) way. It is capable of charging AA and AA batteries simultaneously and has an individual display for each battery you plug into it as well as a charge detector to keep them from overheating. The 4 modes that are included are charge, discharge, refresh and test.
This battery charger sells for $34.99, if not cheaper. Shipping is included
