Battery Test

[mogu83]

Here's a couple of links that a friend sent me about batteries. Lots of information and it looks like the guy did it right. No tests with results like "I think it cranks harder with battery X". He lists his test equipment and uses multiple meters on every test. He throws away high and low readings and takes an average of multiple tests to get his results.
Looks like a report that could have come out of Bell Labs:

Good way to spend some time if your in the part of the world that is not conducive to motorcycling right now.

Those MotoBatt batteries are made in China and arrived on the scene a few years ago. I first heard of them on the Guzzi list where some of the guys are useing them in their big Italian Twins. I put one in my Giro bike and the thing seems to hold a charge forever.

Does anyone know if any of this information is relevant to our bikes since the voltage is slightly different? We can't use just any 12 volt battery.

That is simply awesome testing. As thorough as it gets. I have tested industrial batteries for a long time. These tests go way over the top.

Great tests - but..

No Yuasa or Exide - the most common batteries for our bikes. Would love to see how they compared to the ones tested (almost all of which I've never heard of before.)
