I thought I'd just share a little reading that I've done. I've been looking at lightweight batteries to replace the dying Z battery. I've used a PC680 before, but they're really expensive. Braille seems to be a big player these days, too. Prices seem to be in the $150-200 range, generally.

Well a little reading pointed me to the Deka EXT18L (~$75), and claims that it's the exact same part that others are rebranding and marking up (compare to Braille B261. I don't care to engage a bunch of conspiracy theory nonsense. So more reading and it looks like these Deka motorcycle/powersport batteries are OEM'd to other companies as well.

That's when I found the Magna Power EXT18L, which IS the same as the Deka part that people are flocking to. The local Advance Auto Parts carries these (check website for availability by location). The local Advance also has these on sale. For $24.15. The cashier said that it looks like it's on clearance. Go buy now!

Recap: EXT18L is $24 at Advance and weight 18lbs. A normal Group 35 battery is $50 and 34lbs. This is a 340CCA sealed AGM battery.


Edit: for those averse to tiny batteries and want to quote me the huge CCAs of their man-batteries, the stock Miata battery in in the 300-340CCA range (depending on model).

 

Thanks for the heads up! I got a dead battery in the zenki. Might just go pick one up.

 

there was a point in time that I used a battery out of an old diesel truck (perks of working at a junkyard) that thing had to weigh every bit of 50+ pounds... but it did have 1200cca. amazing how quick that starter turned. lol.

good find Epstein!

 

Are these tall enough to work with standard battery mounts.

 

Even if they aren't, it's worth every penny to find something to make a spacer with...

 

I currently use a bosh mazda miata battery in my SR car. I carried it over from my old ka-t car. 3 years strong!

 

The EXT18L is about an inch shorter than my Group 35 battery. I've seen someone just stick a small 2x4 under it, which is 1.5" tall and not heavy.

 

Someone pick me up two and I'll paypal you the money. None here in Orlando, and price nearby is $98.00.

 

And that's actually what I am doing now with the Optima I bought from you the past year.

 

Which store is this?
Do you know if its about the same size as a miata battery?
