agree sir.. if there are EFB options with almost the same price range with regular batt.. i will opt for EFB due to their durability.. but mazda owners with no immediate access to EFB need not to worry on using regular batt.. i think some owners worry that it may affect their charging system..
what i would like to know is how those LiFeP04 "smart" batteries perform with regular cars and cars with i-stop system..
