I got sick of paying the big money for the resto batteries just for the look and only getting about 2 years out of the last several I purchased. I have gutted three of them now & hidden a lightweight race car battery inside of them. I am on over 6 years on the first one & over 3 years on the second one so far. They also went from like 46 lbs each to about 12 lbs....
I got over 10 years on my first Odyssey...even pulled it out of a years retirement after my replacement sprung a leak (which they replaced under warranty for free) and I put it use for a few weeks with no troubles....11+ years & still cranks over the 440...only replaced it because it was getting noticeably slower cranking when it was colder in the spring so I figured it was time.
