Li Ion Batteries?

Wonder what the jury says on this. Odd they don't list the CCA, AH, RC etc?

 

This member of the jury says I was considering an Antigravity and was willing to pay since they last longer and are so much lighter, but every experienced person I talked to, the word fire kept coming up.

Paranoia to some degree I expect.

I ended up going with an Intersate MTZ-34R and am so pleased, not sure why I was considering paying $900+$200 for a new maintainer, much the prices for these DC models.

Probably awesome if you need that power like a remote motor home, but I don't see it for the F430 and why take any risk.

 

Agreed (I am trying to be as objective and not color other's responses BUT) Fire risk, potential heat, and lack of (at least basic level) technical details worries me. Odd they don't list the CCA, AH, RC etc

I would want a proper head to head and durability test before I jump over.

 

Agree that is odd. Maybe they are trying to redefine how batteries are measured.

At this point my main concern would be with the level of tech and what happens if it goes wrong.

 

Much better power density, but many compromises: do not tolerate much abuse, marginal performance when cold, zero tolerance to deep discharge, can become unstable when over-charged, etc...

Better to keep these for the track.

 

I stuck with an AGM and ended up getting an Interstate group 48 from Costco for my 430 Scuderia. I had to order a new battery tray from an F430 for it to fit, but all good (430 Scuderias have battery trays that only fit a poor quality Optima red top group 34).
Considered a lithium ion, but feel the cost/benefit ratio is not quite there yet. And like the OP, a little suspect with the LiOn car battery industry not using the accepted testing standards for comparison shopping.

 

Hmm....I have LiFePO4 batteries in three vehicles, the oldest one for 4 years now. Absolutely zero issues. I do give them a charge with with the specified charger a couple of times a year just to make me feel better, but no need to keep them on a tender when the vehicle is not active. And I have a disconnect switch on all my 'hobby' cars, but I've been doing that for decades before the Li batteries came out.

Most of the negative stuff you read on the internet about these types of batteries is echo chamber nonsense, likely based on the state of the art in the very earliest days of Li battery tech. We all have Li tech batteries in various other devices in our lives (phones in our pockets!) and don't think about the so called 'hazards' at all.

Like all things, though, buy good products from reliable producers. YMMV.

 

AGM is a less risky option depending upon the vehicle, alternator/generator. The interstate MTZ-34R is 99.99% pure lead.
(99.99% pure non-alloy lead, with an efficient ultra-thin plate design, deeper cycles, rapid recharges, & superior cycle life). $349.95 retail, purchased one recently, directly from Interstate for $289.00....
Plus, I like to sleep at night not worrying about a fire or having to replace my alternator....

 

I was wondering exactly why it was so much heavier than all the other batteries I looked at, clocks in at 49lbs, wasn't too bad putting it in though once you have the bar out of the way.

 

Yes, my shoulder hurt the next day, after installing mine....

 

Braille batteries are what I run here. Outstanding performance. Search the forum for "braille i48cs" and you should find a lot of information. I personally don't use the Antigravity batteries, but many people here do and seem to like them.
