AGM Battery

[ellis8500]

Got my engine set today for storeage until next spring. Removed the break-in oil, refilled with new oil and new oil filter. Squirted a good dose of oil in each cyclinder through sparkplug holes. connected my small AGM, 15 lb battery. WOW, does that thing ever crank that Ford 302. Does better than the battery in my Ford Sportrac. I read here that they are excellent batteries for small blocks but I had no idea that it would be that powerful. I did run it down a great deal, until it was noticeably slower. Connected it to my smart charger which maxes at 12 amps. The charge time was much less than it would be with a lead-acid battery. I'm impressed and will go on record to recommend them to anyone who is trying to decide what to use for a battery. I'm an engineer and live in Missouri so "show Me" has double the meaning. That AGM battery showed me real good. It's an Oddessey PC680-P

I bought the same battery about a Month back, works great, will use it in several things over the season... Like trailers...

Yep, AGM batteries are the best lead acid (paste) you can buy. I use (4) in series for 48 volts for a hot rod electric scooter. With a 700 amp controller and a 15 hp electric motor, that little scooter would beat my Corvette to 40 MPH. Does that give you an idea of the cranking amps of these little 15 lb batteries.

Bill,

Our batteries only have a 16 A/hr capacity, so long cranks are out. Typical automotive starting batteries are rated around 65 A/hr. But ours do have the highest cranking amps per pound of battery.


Odyssey AGM batteries have a self discharge of less than 1/10 of a regular battery, can be charged at more than 20 times the rate and has a 5 times longer service life. Plus when it gets old, it won't leave you high and dry because at the end of service life is still able to crank the amps, just not as long. This is a cranking battery that can be deep cycled like a deepcycle RV/marine battery. No corrision and mounting in any position is also a good feature. As I have been trained by the regulars on this forum, I will post the pictures, just took awhile to find them on the hard drive, then reduce in size to fit here.

Once you bite the bullet on the price, you will never go back to a regular battery and if you don't keep your T for the next 12 years, you won't need to buy another battery.

Hey Bob,

Nice scooter. How do ya hang on to that thing????? The PC680P might not be able to crank as long as a 50 lb battery, but doesn't need to anyway. A good engine should start in no more than about two full turns of the crank. Right????

I have a small Optima in my T now, but I've heard so many good things about the Odyssey batteries that I'm going to try one when I need to replace it. I can pick up a little extra space that way, too.

I like that small battery, I am going to do a sharing thing with it, can only use 1 auto (Dune buggy, water cooled welder or??) at a time, so it will get moved around plenty, later I may buy another if I am still as Happy and find I need to keep it in something all the time...

Mr Bill,

I don't want to hyjack your thread so I moved the electric scooter over to "Electrics". To answer your question, I now have about 1800 miles on that scooter and have yet to roll on all the throttle at once. I would need a wheelie bar for that. If the scooter was a bull in the rodeo, it would have a near perfect record. Of the 5 friends/family members that I have let ride it, only one was able to hang on.
