step 1 in getting my ptroject moving again
After a long break, I needed a new battery to get my bike project moving forward again. Bought this Mighty Max battery and was glad to see it was nearly 13V right from the box. Fit was good in the bike, and b/c the carbs were all empty it took a while to get it turned over, but the battery never gave up. I cranked on it off and on for a while and it never got too low. Always rebounded great from key on to key off. Finally the gas got moving and it turned right over. Idled for a while, and now I have plastic to put on. Do like me: overcome your laziness and get things ready to ride again. Getting a new battery really got this project to the finish line and got me in the mood to get riding again!

After searching everywhere for a replacement battery for my Wgen7500DF generator i finally found this one on Amazon. It fit perfectly and was rather easy to fit in the battery compartment. Thank you Mighty Max for getting my generator ready for any future power outages!
