My Great New Battery Charger
Like many modern families we have need for a lot of batteries. Rechargeable wireless mouse, digital camera, flashlight are frequently hungry for more power. After a couple of years of recharging we had a number of questionable batteries that didn't seem to recharge. Because we use them in pairs and the weakest battery hobbles the pair, it was a chore to find the bad ones and all we could do with them was throw them away. The Powerex MH-C9000 makes those issues things of the past.
It analyzes batteries and displays their true capacity. It discharges a charged battery and displays its actual discharge capacity. It breaks in new batteries for maximum capacity and reconditions questionable ones. It can even raise batteries from the dead, and if it can't it tells you they are gone so you may shed them and move on.
If your household uses a lot of double and triple-A batteries, I heartily recommend it. We got ours from Newegg and it came with 4 of the new AA rechargeables that come fully charged and hold their charge for a year . . . perfect for my digital camera. Link
