If you want to keep the dual 12v setup and factory hold downs on an MEP-002A you can use a pair of 51R batteries (used in Honda) They are just a tad shorter than a 2HN but barely 1/2" difference. I was recently told by a SS newbie that Sam's Club has them for <$60 each. I personally have had excellent luck with Everstart Maxx (yellow) batteries from Wal-mart , but I do not believe the 51 or 51R is available in the Maxx series, just the regular Everstart. Deka and Interstate are also good. Depending where you buy, be aware of the warranty! BJ's carries Exide Extreme with a 108 month warranty, BUT... only the first 3 months is free replacement then pro-rated from there, where-as everyone else is 2 and 3 year free replacement than pro-rated after that.
