I was skeptical about ordering a online battery.
I was told by multiple sources that a h7 and h6 could be used, and ordered the h7 with out making a physical measurement.
The customer service supported me to correct my mistake.
Now i have the battery that i need with a great warranty at a very competitive price.
The batteries are working as advertised. The batteries are strong, my engine's starter is working better and It's nice to have the dual purpose aspect on the cranking battery because I'm powering two live well pumps and an aquarium type bubbler. I did break a screw in post by over tightening but I was able to get the broken post part out and still connect all the needed connections. So far I'm happy.
The battery is very heavy. About 10-15% more than wet lead acid. It works as it should. It did take a few hours to balance themselves as they were connected in series for a 12V RV system.
