Charger: The MQR06 charger with single channel control is small, white and practical. 4 blue LEDs indicate the current battery charge level in each bay. They go out as soon as a battery is fully charged. Before charging each battery is checked. Here If an error occurs, the battery will not charge. How well this works, I can not say because I have so far not yet had faulty battery. Need only two batteries are charged, they can be plugged in for fast charging in the two outer bays. This then goes faster, but suffer the battery life. The 3UTGB batteries Handwarm during charging. It can be loaded of course batteries from other manufacturers, but it should only Ni-MH (Nickel Metal Hydride) batteries are used. I also recommend the Wikipedia articles for Ni-MH technology in particular the section lazy battery effect. Even the smaller AAA 4UTGB batteries can be recharged with this charger.
Batteries: The eneloop batteries from Sanyo are very popular with photographers and rightly so. They have a low self-discharge and keep in operation the 1.2V very consistent and with 1900 mAh also quite long. I also used the batteries mainly in photography. In addition, they also come in a flashlight, a portable radio, a remote control, a razor and the Wireless Keyboard by Apple for use. For flash units or flashlights, there is the Sanyo XX, these have then 2450 mAh, but it can be just about 500 instead of 1800 times recharge.
Would I buy the product again? Definitely! However, enough for me at the moment that a battery charger.
