What contact info did you use to contact CALB itself directly? Did you get any response from them?
Accu-Power USA looks legitimate to me.What contact info did you use to contact CALB itself directly? Did you get any response from them?
How did you get onto this distributor ACCU-Power and "Toby"? No such website, not a good sign. . .
Be careful with these blue metal cased cells. They have the inherent problem of having a part potential on the case relative to the top terminals.This means that they have to be insulated from each other and from the frame or box in which they are placed.i thought all the single cell Calb-style batteries had shells (cases) made of plastic. Now I see some with aluminum shells. Anyone have experience with these for EV use?
Agreed. John's assertion is clearly questionable.The CAM versions are newer than the original blue plastic CALB cells. I bought the original version 8 years ago and they weren't new then. Technology marches on and weight does not equal longevity.
Disagreed. There are, apparently, issues attaining complete isolation between the case and the battery inside. It's either a very high resistance or a temporal issue, but most of the aluminum shell manufacturers will tell you to space them out or risk slow leakage current over time.They can keep the cathode and anode "isolated" and in close contact. Keeping them both isolated from the case is trivial in comparison.
