I thought I knew batteries well. Not well enough though. My question is how do I know the true capacity of the HV battery in a used car I'm interested in buying? I wasn't too concerned until I read the Battery University article on prolonging the life of lithium batteries. A fully charged battery sitting in the hot summer sun for months degrades the capacity fairly rapidly. Some of the cars I'm looking at have sat in the hot California summer sun for two years now, presumably "idle". I doubt very much that most of the dealers know - or would bother - to keep the batteries charged to no more than 50%. (Jeffrey please tell me Georges does, especially with you there).
>Are there test points under the hood that I can test with a meter ?(1kv meter)
>Is there a way to interpret the screen data?
>How about a voltage reading before and after a test drive of "20" miles?
>Can anyone tell me what the peak charge and fully discharged voltages are? I'll compare this to A123's data sheet.
(Engineering level responses will be greatly appreciated and understood)
