The difference is, totally different car.

As for the battery, they both do exactly the same thing and one for substantially less cost. Plus I hate misleading advertizing from vendors.

One weighs 1/3 as much as the other; to me that is not "doing the exact same thing". I am one of those that is seeking to eliminate weight, particularly high CG weight. Not everything is simply lowest cost. I only am looking to know what the other (besides $) compromises are of the AGs

So lets do a test. A professional driver will have extremely consistent lap times.

Lets put a lead acid battery and then a li-ion battery in the same car and do 5 laps each and take the average of each run. Start the vehicle first before the driver gets to it so they cannot tell which battery they have.

And like I stated further up, no added advantage to the vast majority of us. In competitive racing at the world class level, ever bit counts.

That's great. You've stated your opinion several times. It would now be a good time to stop hijacking this thread.

EverStart Platinum AGM Automotive Battery, Group H6 12 Volt, 760 CCA..... $179. You decide

Oh, I didn't know there is a post limit on a thread.

Anyway, I answered the OP and then Scott at AG tries to limit my free speech. Whatever happened to free speech in the USA?

Did you ever find out why a 40 Ah = an 80 Ah.

B Russ

To defend AG, I use LI batteries in my boat. They were $650 each but the weight savings and the ability to monitor them with my phone is worth it to me. Also they discharge at such a low level when not being used.

Whats wrong with this picture

Porsche_nuts

These lead acid vs lithium battery threads are as bad as

0W40 vs 5W40 motor oil, CL vs 5 lug, manual vs PDK, threads.

Like a mad merry go round that you cannot jump off of.

You forgot 1. vs .2
These keyboard cowboys fail to realize that every one of these online pi$$ing matches just makes them look petty and insecure.
Not a good look.

I believe that is a different sort of 'Odyssey' then what the shopper was intending to go on.

Hmmm ... love these threads!

Lots of selling, though ...

Thought I'd chime back in. Thanks for all the great responses especially IXLR8 and Scott at AntiGravity. I really learn a lot from you guys. I think I would be inclined at this point to replace my 991.1 GTS battery with the Everstart Platinum or Interstate. I also have an M4 which is my daily driver. it comes stock with a Li ion battery which is now about 10 yrs old and will most likely be replaced by the AG version. How is that for a happy compromise among sports car lovers? The low weight of a LI battery is pretty cool if you can spare the coin and I do think the ability to jump start a dead battery with the push of a key fob is a pretty ingenious selling point

The third from the right might appeal more to the female Porsche enthusiasts.

I picked up an Interstate AGM Group H8 from Costco today for my 991.1 (base). That's what their chart recommended. That thing is massive compared to the old Banner, but it appears it will fit in the tray. Is group H8 ok?
