I'm looking to save some space and keep the battery up front as I work on the turbo 5.7 project for my Coronet (still street legal, 10.xx goal). These Braille Batteries look interesting and have a non-standard PCA rating to denote 'typical' use. The 5.7 will be stock CR controlled by a MS3 gold box, which size of battery would be the right balance? Can the PCA rating be reliably used vs CCA since it'll never see cold weather?
Thanks

Most of the Braile batteries are just a Deka brand AGM Motorcycle battery with the cranking amps fluffed up by the "Pulse Cranking amps" number. They get that number by doing a 5 second load test instead of a 15 second. Apply about %40 to any battery's CCA if you want something close to the PCA. The only thing that would really concern me would be running fans and pumps with the key on engine off. I do lots of KOEO stuff with my car and I never sweat it no matter how many passes I make in a day.
That being said I know lots of people use them and like them. I am the GM at a Interstate Battery Distributor and have worked for them for 22 years. My Battery game has to be strong, I remember like 15 years ago when my battery died at the track, your friends don't go easy when you are in the battery business lol. I take the weight penalty and just run an Optima Yellow Top. If I were to change I would likely go with a lithium option as they are getting better and cheaper.

I havent seen a lithium battery get cheaper anywhere. Even that GoLithium brand went from $749.00 to $900.00 plus with charger.

That's a good point on the KOEO stuff, with the big block in the car I would in the heat run the fan + water pump for a few minutes when coming back into the pits.
Looks like a comparison of Reserve Capacity is the ticket for that?
Red top has 90min (yellow would be more)
a 'larger' Braille 147-B14115 has 25min, so that's a considerable difference.
Saving the footprint is what I'm most after - to either run a charge pipe between the battery and rad or for placing a w2a intercooler over on that side.

at a glance it wasn't clear - can you jump one of those or if it dips below it's threshold the only option is to charge with it's dedicated charger?

I was told that you can only charge it with the special charger if it drops below a certain level. My friend Brian Coleman just accidentally ran his down by inadvertently leaving something turned on. When he hooked the Optima charger up to it, it didn't wake up the battery. He called antigravity and they said just jump it and run it and it will be fine. So I don't really know what the real answer is to that question. I forgot my fan and water pump on one time when I was wondering around the pits. I came back 20 to 30 minutes later and tried to start the car. The battery wasn't stone dead or shut off. It cranked over about a half a turn, but that was it, it didn't start. I put a jumper pack on it and fired it right up. It charged up from the alternator.

It will handle the cycling better. I just retired mine after 10 years, it was still working fine but when I pulled the cover off of my box I had some corrosion meaning it was starting to gas a little or the seal around the post had given up. I have only messed with some lithium batteries that people have tried to recycle with us. They charge incredibly fast on conventional agm charger and they are very powerful. But, for some reason people are throwing them away(most of these have been motorcycle batteries) and the few I have messed with have been seemingly good so why did they toss them?

Those are the giant truck battery ones, 43.8lbs for the yellow top. Still not light by any means.

Battery is brutal. 90% of the time if someone is having optima problems they are doing something wrong somewhere. We sell maybe 1000 of them a year and see very little failure. Most of the problems come from show cars, race cars, and things that don't get maintained and properly charged. If you have to have the 60lb yellow top to function in your car there is problems.

At the time, 60 lbs in the trunk and the battery lasting well over 12 years was a plus for me. Then I needed to shed a bunch of weight, sob iui t came out. I opted for a 8 lb. lithium battery.
