You should be grateful you got seven years' (maybe eight seasons) service out
of your batteries.

It isn't posible to tell whether you batteries are in critical need of
immediate replacement without running a test, but it would be a generally good
idea from a preventive standpoint based simply on their age alone.

Best flooded battery you can buy is probably a Rolls or Surette. (Same battery,
two different brand names). I was recently introduced to Meridian AGM
batteries, and I think they have a number of excellent characteristics as well.
