The lightweight battery market has gotten fantastically competitive, meaning lightweight options, including those that are Lithium Ion, now cost as much as AGM spiral cell options did just 5 years ago.
We subjected our daily-driver 2003 Ford SVT Focus to yet another rallycross and a track day at Sebring. Then, we walked out to it one morning, clicked the unlock button, and were met with nothing. A quick peek under the hood revealed a battery box covered in acid.
We topped up the battery’s water, slapped our NOCO jump starter on it, fired up the car, and drove to work. Then, lunchtime came, and we had to jump the Focus yet again. A full charge and a multimeter confirmed our fears: Our battery was toast. We’re guessing something internal was shaken loose during one of the rallycross’s many bumps.
It was time for a new battery, so we started shopping around. We figured this was a good opportunity to save some weight, but we also wanted something that would put up with all of our abuse. And, of course, it couldn’t cost much money.
After lots of deliberation and a few testimonials from Focus forums, we settled on the Odyssey PC680. It weighs 15 pounds, handily starts our Focus, and can be found online for just a touch over $100. Plus, Odyssey (and many of its happy customers) claim their batteries are nearly indestructible, as well as spill-proof. We modified the factory hold-down, fired up the Focus, and pointed its nose south: It was time for another rallycross.

What's your favorite low-buck lightweight battery? I'd like to see how it compares.
Thanks!
I've got a Braille B2015 installed in my car.

FWIW I'm in the process of replacing my Odyssey PC680T in my TT/autoX CRX ... it lasted 7+ yrs
Walmart Lawn Tractor battery. 11# (confirmed on Walmart bathroom scale, located two aisles over from battery rack). $25.00. We put a new one in the FSP car every 2 years or so.
I ran a 680 in my last two cars.. great battery

I am running that exact battery in the Accord. It has unleashed 2 liters of fury every time. Even when Tunakid #1 drove it and it stalled a few times in a row, it restarted each time without an issue.
And it made way more room under the hood.

I got the same battery In my FSP/Challenge car, works like a charm.
Got it on sale plus with a $5 coupon it came out to 15 dollars total!
I really want to try out one of the lithium iron batteries from Battery Tender but for a 6lbs difference I dont think it justifies adding a zero to the above price.
I like universal battery brand, lots of different sealed batteries for half the cost of the name brands. I have bought hawker/odessy clones for $45 shipped. They last just as long, always fire up weigh the pretty much the same and fit in the same space. The only difference i ran into was the terminals. 2 10mm bolts and a few inches of scrap copper tubing fixed that problem
I have bought two pc680s. One is going over four years old and the other was stolen! They are awesome batteries.
