new non sulphating battery from Soneil

Here's a Soneil AGM battery in the more common Group 31 size that you can lift easier and that provides 250 AH of capacity from two of them in parallel: https://soneil.com/product/12-efsl-125/

And here's a Lifeline AGM battery very close in size, weight, and identical 250 AH capacity from two of them in parallel: http://lifelinebatteries.com/products/marine-batteries/gpl-31xt/

I wonder how the two Group 31 models compare in price and life cycles?

Also note the relatively high internal resistance of the Soneil battery ... so I wonder if it will charge as fast as the competing Lifeline Group 31?

I guess that a big difference between the two batteries is that the Soneil is manufactured in China.

This and Trojan’s new lithium...exciting times.

What parameter seems special for a 110lb battery?

How much and how could I get one in Denver?
