That company has been making them with that arrangement for years...The only true conventional,maintenance free AGM battery was/is the turbostart unit...IMO the "battery in a battery" set-up is just another set of connections to make problems whether it's their battery or a home made one..With that being said they do have many happy customers that haven't had any issues...

Someone else posted that same finding of a battery in a battery. Is this one quite light in weight? Or is it about 50lbs? Heck if my agm red cap is hollowed out, I can just put in a replacement when it dies.

My last one was an AGM and I dug it all out as well. I wasn't sold on the extra cable connections is why I ordered a new battery just to get what I already had done.

I dropped the superstock battery back off and they replaced the loose negative post without any question. All good now. That battery was $355 and the red cap 27 was $265. He knocked a little off for paying cash. My receipt says 48 month warranty for these batteries. The 27 group is a battery within empty battery case. The superstock is not. That thing is a boat anchor. Right now i’m happy with purchase. At this point we’ll see what their life span is.

Ok the Superstocker is a boat anchor. How about the Red cap 27 weight?

Weighed the red cap 27 and it comes in at about 30 lbs.

That is a bit lighter then the usual. Thx

After sending some pm's to 6PKRTSE I decided to do my own battery in a battery! The first day I turned it over and cut the bottom out. Then I got worried about getting lead poisoning! When I got back to it I started carving out one of the middle cells. The first cell took about 2 days of my spare time. The second cell took about a day and the last four I got done in one day. I learned how to pry things apart and got more efficient. I have posted a picture looking in the bottom with the PC925 installed and another of the battery in a battery installed. It works great and looks great! If I have a battery failure I just have to replace the inner one. If anyone has a dead group 27 red cap that they would like to get rid of I would like to do another for my other car. Send me a pm or e-mail me at moparjohn@frontier.com
Thanks!

Hey that looks familiar. Nice job. Yeah, I have another dead core here to gut for my next project car someday. I may even do it for the trunk of my race car just for the "Mopar" look still.

I have 2 dead red caps gathering dust in my basement. I'd like to try to convert one if I ever gather the time and ambition.
But I could part with the other. I don't want to try to ship it, but if you get up into the Chicago burbs or are still interested in November and coming to MCACN let me know and we can get together.
I ordered a group 24 in March, and heard from Jims that they took over Antique Auto Battery in around Memorial Day. They said they'd have my order from March shipped in 3 weeks. I finally got it around a week ago! I haven't fired up the car yet, but hopefully the battery is good after making me wait 5+ months!

talked with the new Turbo Start Company Rep today , New agm Resto Batteries to be out after the first of the year. Ill post more info as is available.

Just received a battery from the former antique auto battery, took about six weeks and it is GREAT! An employee from Antique Auto Battery took it over, they were personable and professional and supplied the product, give them a shot. Bing Antique Auto Bsttery and give them a call. Ps their new web site was not up 2 weeks ago, that is the reason to search Antique Auto batt.

So for Turbo Start, who or where is a company rep?
Are these the same as Fred Gilmore formerly rep'd for?

I contacted Turbostart thru their website. I emailed them earlier this year and the person that got back to me said late 2018 or early 2019.
They should update their site with info, but they don't. They list the batteries but say Out of Stock. Wait and see game.

We are making the yellow, red and green battery again . I have read a lot on this post and AAB puts smaller batteries inside of there batteries . we will be making the correct CCA Batteries . Ours are AGM batteries, however I'm reading where you guys are being able to change the caps out to different colors. ours will be glued in so you cant change them and we do that to keep a good seal. Thanks guys hope this helps

There is a yellow cap Mopar battery on ebay. It is supposed to be NOS.
