the only type I've bought in 25 plus years. Optima was my first choice years ago until manufacture of them moved south. Orbital has been my other choice. Except for my 4wheeler then just Wally world AGM, now I have had great service with Optima batteries many lasting past 12-15 years. Red tops and blue tops. I prefer the deep cycle over standard, works better for running a Ready Welder. That leads to my reason for dual battery set up.
A larger secondary battery added to the system can be done to replace the motor cycle one too but needs to be relocated
I always buy their top battery and so far, in my cars that sit much of the year, including several months over the winter and sometimes 3 or 4 weeks at a time in the summer - they've all lasted past their "warranty date". Had one in my Silverado and that truck often sat 3 or 4 weeks at a time (big truck, long and cumbersome to park) and it did just fine.
I'm not sure how you came to that conclusion? I run AGM batteries in everything - Tractors, trucks, ATV's, Boats, etc. Being in Texas, we know warm running conditions and I get excellent service from AGM batteries (Mostly Odyssey, but some Northstar), with many lasting over ten years and none less than 7. With no need to add water, and no corrosion at the terminals, it's a no brainer for me in overall cost of ownership. I regularly remove brand new batteries from vehicles to replace with AGM due to several manufacturers (I'm looking at you Toyota, Ford and Polaris)batteries getting corroded terminals within 6 months.
Yes it is - very similar, venting to prevent gas escape that happens with standard batteries. The acid is held in "fiberglass" not free like flooded cell lead-acid. It is more controlled by the glass.
LOL - no kidding. Even a product I've used on my car batteries for years helps. I use a product an electrician showed me years ago on some connections, No-Ox or something like that. It's a help, not total prevention on cars, it's made to prevent oxidation on terminals in your business or home electrical system in high moisture areas.
I am able to re-purpose the OEM batteries in clay target throwers, sprayers and other menial tasks. You can coat the terminals, but the caps still leak. Replacing a battery cable on a modern Ford Super Duty Diesel is expensive and time-consuming. They all require maintenance and last 3 years or less. I can take a new truck, swap to AGM batteries, then go about my life for the next ten years without a a single thought given to the battery in it. That's my Logic in that.
