90% of all batteries made use recycled lead..that reason to discard a battery is absurd. As far as the video above, It means nothing as far as anything I would do with it, same for 90% of the people who buy one. Seriously? You are telling me you are putting a 500a load on a single D31 battery?
LOL...Fire up the load tester cold and put it on the XS first so that you can eliminate any doubt in my mind of unbiased testing in a XS Power sponsored video.
...the Author lost me when he explained breifly that the heat buildup in the tester was creating a lot of resistance....and obviously the video results reflect that fact...
but hell yea, 9.3v after a true 30 second 500 amp load test is allright in my book, I don't compete and the only comparison that will help me and many others like me is the same test between one of those D31's and a regular wet cell D31 or even a Yellowtop.
