The ones I was thinking of are like 6 vertical cylinders 12 V . The yellow ones are deep cycle I think ? The red are general usage . No sure about the blue ones .Maintenance free. I Never heard of the glass mat .
The Optima line is widely available and popular. They are the AGM type. They generally make only 12-volt batteries in automotive sizes. Optima batteries are recognizable by their "six pack" shape resulting from the spiral construction of their cells.

Unlike flooded batteries and some AGM batteries, Optima's products are all constructed essentially the same way, with just the terminals being different.The ones I was thinking of are like 6 vertical cylinders 12 V .

Any VRLA (valve-regulated lead acid) or SLA (sealed lead acid) battery is described as maintenance-free because it doesn't release hydrogen and oxygen gases, and so it doesn't need replacement water. They still have maintenance requirements, of maintaining proper charge voltages and controlling the temperature of the battery.Maintenance free.
I'm wouldn't be surprised if most people who have heard of AGM batteries don't know what that term means.I Never heard of the glass mat .
The spiral-wound construction makes physical sense, and was an early design... perhaps the original. If it is now a marketing gimmick it is one with significant consequences, because it constrains their case design and reduces their ability to pack active battery content into a rectangular space.A marketing tool?
I agree that crimping larger cable is not a job for pliers.Al, while it works now, you might want to look into having someone crimp on new cable ends with a real crimper or solder type ends. Crimps with a pair of pliers may well loosen up again.
Battery cables look bigger than 10 gauge on all the recent photos of Escape battery installations that I have seen. Inverters appear to be supplied by an additional set of similarly large (or larger) cables, which makes sense.Check what gauge wire Escape used on your trailer, 10 gauge is barely adequate, especially with an inverter. It maybe time to replace as you may have other trouble spots waiting.
