Jeff “Coding Horror” Atwood beams about his La Crosse Technology BC-900 AlphaPower battery charger, which as chance would have it is the exact same battery charger I purchased a couple of months back at all y’all’s suggestion, but haven’t actually yet had a chance to use, as my AA usage mysteriously has dropped to next to nothing.
You can also switch between four different readouts after the mode is engaged: time elapsed, voltage, and two mAh (I assume one is charge/discharge rate, not sure what the other one is). That refresh mode is incredibly slow– it’s basically discharging and recharging over and over– but it really works. It can take marginal batteries from the brink of death and give them new life.
But you don’t have to care about any of that; if you just drop 4 AAs or AAA batteries in the device, it will charge them fine. I spent several hours after I got it plugging various batteries in it, trying different modes, and watching it work. I’m not sure what the exact definition of geek is, but I think “enjoys recharging batteries” has to be very high on that list.
