New battery probably...

..But going to clean connections, both ends, and charge over night. May consider rebuilding starter on my 1997 California. I have not done that yet. But with jumper cables she spins fine.

Have a PC680 Odyssey in there now. But always felt not really as stout as a PC925. So If I need a new battery, I'm probably going with a PC925L. I have not had battery issues when I run the Odyssey recommended batteries in my vehicles.

I've had good experience with the Odyssey batteries.  But, I also got the same life out of a $49.00 Interstate lawn more battery in my SE.  :BEER:

I agree, dilligaf.  Cheap batteries have given me service equal to name brands for years.  I'm on the 2nd year with my $33.50 generic 18 amp-hour AGM battery in the Mille.  It cranks like no tomorrow, even when I was testing the ignition system in the garage and repeatedly cranked with the kill switch off one snowy weekend.

I have an Odyssey PC925 in my Ambo that was purchased in 2003....that's now 12 years old, when I put the Tender on it monthly it barely needs charging.  The Westco in the Bassa lasted 12 years.  Replaced in 2013 with the same.  My Mills AGM in the Wing lasted for 3 seasons and puked....replaced with either an Ody or Westco.   ;-T
