I've been using a miata battery in my EF for some time now.

While it is a LOT lighter than the honda battery, I have been on the lookout for something even lighter.

I know lots of people go with braille ($100+) or other brands, but I wasn't willing to shell out so much.

After comparing the popular deka lightweight models on specifications, I decided to do my own research.

In an online search, I found a link to this site which has the specs including cca's and weight + decent prices for lots of batteries:

Part No.-----Cap. AH-----Length (in)-----Width (in)-----Height (in)-----Weight (lbs)-----CCA-----Cost
YTX12-BS-------10---------6-----------------3 7/16---------5 1/8------------7.5-------------180-----$50.96
YB14L-A2-------14---------5 5/16-----------3 1/2----------6 9/16-----------7.6------------190------$38.89

If you buy a battery online, they won't ship it with acid in it. So I got the battery then went to a Batteries Plus store and they filled it for $2.00.

This battery is very light and starts my car better than my Miata battery!
