The Battery Lesson
This Lesson comes from an 8 month old battery that started behaving like my original
3 year old battery In my 2008 1200R.
The Bike would start But that first engine roll over was slow. Sounded like I had some
super hi compression setup.
Battery,,,8 months old HD AGM Mat,,,Has lived on the tender,,750ma
The HD AGM Mat batteries are very good compaired to most out there.
All makes have a rate of failure, even $200 dollar models..
My Bike Is riddin most weekends..
I Used my home made Kit analog meter and My Home made Kit Digital Vom.
(accuracy of the analog,,,+- 5% give er take)
Resting off tender for three days,
Key On,,lights n all,
7.0 VDC,,,,,,,,,,VERY BAD
Ok the above Battery passed a "OUT OF BIKE" load test.
Got ahold of my "trusted" HD wrench at HD..This Guy Is the Sporty guru.
He retested, It passed a second load test,,,He stuck It In a sporty,,,FAILED,,7.0 VDC
while slow starting.
New HD AGM Mat battery
Still out of the bike:
Digital 13.02VDC,,,Odd I know
My Wrench said a out of bike load test cannot simulate an In bike crank completly.
BTW the Bike spins up Kick ass fast now.
The Game Is how fast I can Bump the start button,
One revolution Is all It takes,XD
During cranking the battery should remain above 10 Volts
A partially shorted plate I musta had,,
It would have left me stranded in the near future,,
Here ended the Lesson
