La Crosse Technology BC-700 Alpha Power Battery Charger
The BC-700 will accept up to four NiCd and NiMH AA and AAA rechargeable batteries at the same time, with the ability to change the charging current and thus the speed with which your cells are recharged. The default current is 200 milliamperes (mA) which takes a little over an hour to fully charge four low-discharge batteries. Switch the charge all the way up to 500 or 700 to charge your batteries quicker, though faster charge times may not always refill the cell to its fullest potential. Some chargers are either slow or fast chargers by design, this one gives you the choice to have it either way; not many chargers are built to perform in such a fashion. This option is primarily what puts it at the top of the list; but there are three other function modes that also make this our favorite charger. There's a discharge mode that can drain all of your batteries completely so as to avoid any internal memory issues before recharging to them to their proper capacity, in addition to a test mode and a refresher mode. The first one checks your batteries for the amount of life left inside of them while the other one can do a quick top off of your cell if its partially charged. Four LCD displays give exclusive readings of each battery you're charging and the BC-700 even has an internal monitor to prevent your cells from over-heating or becoming overcharged.
