Almost time to replace that ancient 40 pound lead brick. Technology MUST have improved enough to get the weight down. Anyone have any lightweight battery recommendations?

Ahem, let me get this started...I hear in other forums of people using 18 lb miata batteries, rider mower batteries, etc...

I bought a lightweight battery from Summit. The cold cranking specs are 800CCA and it weighs around 26lbs. This battery has perfromed better than the Optima I once used. The battery has suffered from neglect and returned back from a Winter storage where the floating charger became disconnected and is still perfroming well 2 years after that fact. The Optima SUCKED!! and after trying them in 2 vehicles with a couple of warranties, I gave up on them. I made a plywood adapter base to mount the smaller casing race battery and a custom hold down angle with all thread and 1/2X1/2" angle so it is competition legal. I will relace it with the same type when it fails to hold a charge and pass a load test like my Optimas did (almost every Spring time it seemed.) I think they are sold under the Odyssey brand now at Summit.

26 pounds sound pretty good. I've heard about a battery called Dyno-batt or something that is also pretty light (but expensive).

Somewhat suprised at the lack of responses - I've seen 30 post indepth discussion about saving 8 pounds on 4 expensive aluminum calipers and no one cares about losing 25+ pounds with a lightweight battery?

They loose a bit of total capacity, but, save the weight!! http://www.stealth316.com/2-dynabatt.htm

A little weight isn't bad(when it is something you can relocate). Luckly Corvettes put in the back, but on the wrong side.

:iagree:

might be the most cost effective way to loose weight.

Just buy a Vertex Magneto dist. With it you can delete, alternator, abattery, starter (need external starter), and coil. :D

We ran them on out race cars, still have two of the from my dad's race cars. :cool:

Seriously, I think Oltama has a self contained lightweight battery. :thumbs:

Yo SPYDER, you gotta give me a little time to try and find out for you. Here ya go..
http://www.odysseybatteries.com/

I inquired using specs from my Vette, No ac, no radio, no p/windows, and a 100amp alt.. The BIG one is PC925T which has 925 cranking power and weighs about 24.5 lbs @ $106+ship. They do have a smaller one that the owner even uses himself in a street rod w/ac. Give 'em a call there is an 888 # on the website.

I might joke around a little, but I do come through. :thumbs:

OK you guys are coming through! Here is another choice - http://store.miataparts.org/wessealbat.html
25 pounds.

I clicked on the dyno-batt page. That thing looks like a toy battery it's so small, 13.5 pounds, that may be the way to go!
