I have a Sirrus Smart charger. It is about 10 years old. Do you think it would be ok to use it on the ''Sanyo'' ''Eneloop'' 1900MA pack I have? It has a 3 position switch for charging. 250, 500. and 1000. Do these numbers represent the pac size to be charged or the rate of charge? Got find the directions for it! Capt,n
I wouldn't use that charger on Eneloop batteries. It charges at a constant high rate @ over 1A. Those batteries will not be happy with that high rate of charge. The switch just changes the charge characteristics and not the overall rate.
Sanyo states that these batteries can be fast charged on occasion but overall, they should be charged at the 1/10C rate if you expect them to live a long life. While these batteries exhibit excellent self discharge rates, they are still a rather high impedence, NIMH battery. One common characteristic of these sorts of cells is they don't tolerate high charge rates well.
