Glad you had a good responce Bonkers, I too am in need of a new one & have been doing some research ,,Deka EXT20L only has an 17.5 ah & 270 cca which seems a little under powered for a Harley . Think I will go at least a EXT30 it has 325 cca ( cold cranking amps } or even bigger , depending on price ,good luck with the exchange
Just took an SSB HVT2 out of mine. Been there for 8 years. I keep a battery tender hooked up when not riding.
Just replaced my battery after getting 7 yrs life out of the original HD one from new, PHD charged $182.95 for the newey.Considering the time since this last posting,not a big hike in the price IMO.
