Need some help with a final decision on my batteries etc as I cant make out what is just marketing from sales people and what is people's real experience with this. Thanks

Battery for fridge etc no cranking.
Alternator charging only at the moment may put in a solar panel later.
So need faster charging with less driving.
Lots of corrugations where I live.
Would like battery longevity ie more than 2 or 3 years.

Looking at the Optima D31A 75Ah X2 @$368 each
Century c12-100da AGM 100Ah X2 @$288 each

Do the Optima's really charge faster, last longer, and are less affected by vibration or is it all marketing. Am I better with lower Ahrs but with a faster charge and a longer lasting battery?

Ctek DC DC D250S Charger: Is this worth the $250? Will it charge the Optima's faster and fuller or will it make little difference.
