I can't directly answer your question as to which batteries with the slide out tray, but do have some thoughts on your battery choice. My research says a battery's AH, size and weight are pretty standard in the industry. Some batteries of the same AH may weigh a little more than others, but not a lot.
I previously had a Lifeline 100 AH AGM for years. Great battery. When it gave up, I replaced it with a Universal 100 AH AGM. It has proven itself, and cost a lot less.
This link will give you the data and cost of the Universal batteries.
