I’ve tried rechargeable batteries — mostly because I hate paying for new batteries all the time, and getting rid of the old ones — but I use the crap out of my batteries, and inevitably I wake up one day and those rechargeable batteries I shelled out for no longer hold a charge. The La Crosse BC-900 promises to remedy that problem; its refresh mode will bring those dead batteries back to life.
The BC-900 works with all NiCd and NiMH AA and AAA batteries, even ones that’ve succumbed to the false memory effect. With four separate LCD displays you can monitor each battery’s progress in any of four different modes: Charge, Discharge, Refresh, and Test. It prevents overcharging by monitoring battery heat.
For $45 the BC-900 comes with 4 AA and 4 AAA batteries, C and D adapters, and a travel bag.
