Review: New battery, not old stock! - First full charge then discharge to 10.5v with a fast bounce back to 11v. I'm happy so far. This was a 2 amp rate and it held extremely steady till the end. A heavier test will be next. Before I run the second 20 amp hour battery test though I have fantastic results from the hundred amp hour battery that I also purchased! I had to baby my tester as much as I could to pull enough juice out of it in a reasonable amount of time but I managed to get 99.12 amp hours and roughly 9 hours 57 minutes at about an 8-10 amp draw rate. I'll admit these are the very first charge and discharge tests on these batteries that I've received within days of this post but I will continue to test and I will update on each of these batteries if anything changes for the worse. So far though $120 for $100 amp hours and $46 for 20 amp hours is a pretty good deal!
Review: Great product - Works great haven't had any problems out of this battery. Have been going o 6 months now problems
