I ordered my Red cap battery from Battery Central in Dec 2020. I spoke to Wayne who was very helpful and answered all of my questions. The battery he gets are from Jims Battery. I did ask him then what battery is inside the case. It is an AGM and it was 2 brands he uses. Can't recall which ones. I got my battery in 5 weeks. At that time, he did have Turbostart in stock, but did not have the specialty double shipping boxes for them. So I got Jims Battery product. So far so good with this battery.
