Hi guys.
Just want to share my impressions of this charger I purchased while travelling overseas.
As it can be expected from Sanyo it's a very well specified charger. The best thing is that it features a peak voltage control as a primary charge termination mechanism. Here are all safety functions according to Sanyo:
1. Individual charging control
2. Timer control
3. Peak voltage control
4. Minus delta voltage detection
5. Temperature control/protection
6. Alkaline battery detection
7. Short circuited cells detection
The peak voltage detection or 0dV (which is the proper way to charge NiMH cells) is backed up by -dV, in other words if the electronics fail to detect the zero voltage slope the -dV kicks in. As a last resort there is a timer. When charging 1 or 2 cells you can chose between the quick channels charging at 1275 mA or the slow ones charging at 565 mA. 3 or 4 cells are always charged at 565 mA current. 1 or 2 AAA cells are charged at 310 mA. All this is enclosed in a very compact body and plugs directly into the wall (via cable in Europe and with a foldable plug in the US). Works worldwide on 100-240V.
What can I say about the charger in use? The advantage of 0dV charge termination is obvious especially when charging at 1275 mA. The cells get heated only to about 40 degrees C. In fact there is no difference in cell temperature at the end of charge when charging fast and slow.
To me this is all a charger should be, no fancy stuff just a properly specified charger with plenty of overcharge protection. I gave away my LightningPack 4000N and will use ths Sanyo instead. The only thing that is missing is a discharge function and a separate light indicators for each channel (it has only one LED that turns off when the last cell is ready).
Last is price. I paid about 25 Euro for the charger packed with 2 2100 mAh cells in a word low for Europe.
