I would love to have state-of-the-art batteries but their high cost, coupled with my old guy recalcitrant stingy attitude, will cause me to suffer through the useful remaining life of the lead-acid batts I have now.[emoji4]

Aftermarket, they do not have an upgrade yet.

Good point.
Will they hold that charge?
