1. Do you load test batteries?
2012 was the first year we load tested.

2. Did you load test the EnerSys Genesis NP18-12B 2013 KOP and FIRST Choice Batteries?
Not yet, we plan to.

3. What was your results?
See attached spreadsheet (some batteries listed not tournament legal). We have found some batteries were not manufactured correctly, this may explain the lower CCA you are experiencing. For measuring capacity, our batteries were discharged at a 10A constant current rate. The equipment used was an aviation battery tester we have access to. Looking at the resulting voltage plots, we could identify bad cells and other problems.

When we had a battery with a bad or weak cell, we would quickly recharge the battery in an attempt to recover capacity. I'd have to check what the fast recharge rate used was, but it was at least 10A. By the way, in case anyone thinks this was dangerous, we the facility we had access to was capable of handling any issue which could arise.

4. Can you confirm if your batteries meet your team spec?
We'll let you know when they are tested. At this point our "spec" is no bad cells and >12Ah. We've found new batteries come in at 14-17Ah typically.
