If you have rechargeable batteries, this charger is a no brainer.
If you have eneloops, how is this ~$60 charger better than the ~$6 charger from Sanyo?
Update: Some days you get the bear and some days the bear gets you.
First, what is the model number of the Sanyo charger? (Update: NC-MDU01 for the 2-battery unit powered from a USB port and MQN04 for the 4 battery unit powered by mains.)
Second, does the Sanyo charge each cell individually or does it connect them in series pair and charge the pair, a strategy which eventually destroys the weaker of the two batteries? (Update: The NC-MDU01 charges them individually while the MQN04 charges them in series.)
Third, what is the normal charging current of the Sanyo charger? (Update: 850mA for a single battery plugged into the NC-MDU01 and 450mA when two batteries are plugged in. 250mA for the MQN04) My LaCrosse BC700's normal current is 100mA (Update: 200mA) and my Maha MH-C800S 8-battery model defaults to 500mA (Update: 1000mA) but can be reduced to 200mA (Update: 500mA). More current is worse since it heats up the battery and damages its internal structure.
Anyway, I use the LaCrosse almost exclusively. The Maha is used when I have a lot of batteries that need to be charged in a hurry, but that's why I bought it.
