Hi,

It comes with passion that I have parked my national grid for almost 6 months now. My dream is to see my grade B lithium battery survive for next 20 yrs

Somewhere I did read that as batteries get old the internal resistance rise up

I would like to know/sense of when it is rising.....I don't know.
Is there a way I can reverse the chemistry ?

I am at a desperation to see it aging with me as lithium cells are not getting cheap
