That's beyond impressive. I'm guessing these have to be ordered direct? Any idea on pricing?
Not to doubt that battery chemistry but as far as that youtube goes without any enviromental data that does not really impress me obviously not cold out and how warm was the truck prior to that, she sounds warmed up to me. Alot of smaller batteries out there with a warmed up engine will more than likely perform well on multiple start tests.
What would impress me is if it was freezing or less out and the block was at that temp also, but then it would no doubt fall flat on it's face.
As far as I am concerned and I have this conversation with clients all the time, the reality is is that the best bang for your buck is still a regular flooded battery especially one that you can top off. And yes I do design/specify battery systems with AGM/GEL units. The regular flooded is the most charge rate (voltage, current) tolerant and can withstand abuse as long as you maintain a charge on it.
These modern chemistry units are more charge parameter picky in regards to the voltage and temperature of the battery. Automotive alternators are not really that exact when it comes to their charge rates and are also not temperature compensated. The classic scene in the marina is watching an AGM/Gel battery walk of the boat months after it was installed because the automotive style alternator killed it,and the seller/manufacturer had charging parameter info buried deep in the fine print. The optima spiral is a design attempt to make an AGM style battery that is less charge picky and be able to have a good enough plate surface area for quick amp supply. I'll be intrigued to see how these AGM batteries such as Sears fair in the Auto world, of course on their website I was not able to find any charging parameter specifics.
The Lithiums I am watching closely from a deep cycle perspective a lot of power in a small package, some of the house battery banks I install are size large and space is off the essence I'll be intrigued to see how they work out a couple of years from now.
Oh yeah what do I have in my truck, hybrid Deka Ultimates

, 2 years on and still doing their job.
On another note, from a regular flooded standpoint there has been for a while pulse charging technology that aims to reduce battery sulphation. They come as either an add on or as part of a battery charger. I have had good results from them and recommend/supply them. On a personal test when I first tried them out several years ago I used one on an old dead battery that I had lying around my shop. I used it on my Jeep and the battery did indeed come back to performance OK and lasted about another year or so.
