Last Thursday we got a nice day after the big cold front and I did my quick walk around and put on my gear to go for a ride. I unplugged the battery tender maintainer and hopped in the saddle, engaged the ignition and yep you guessed it, NADA, nothing, zilch. I pulled off the front cover and tested the (factory) battery which was reading at a minuscule 1.36 V. I checked the maintainer and it was working properly so the battery seriously cratered. I got online on Amazon and ordered a YUASA AGM battery and a NOCO Genius 3500. FFWD to Tuesday when the battery was delivered. I unpacked the battery and put the acid in per the instructions and let it set for a few moments before placing the cap on it. I farted around a little while in the garage and then walked out to the drive where I had the battery sitting, under the battery was a pool of acid. Sure enough the case wasn't sealed properly on the bottom and the acid was just leaking straight through. I got out the water hose and baking soda to clean up the mess and had to restrain myself when I called Amazon. Fortunately Amazon was great and the immediately issued a refund and told me to dispose of the battery properly. I ran to Autozone and to my surprise they actually had a 20 series powersports battery in stock and ready to rock. I got the old battery out and installed the new one and all is right in the world again. Oddly I hooked up the old battery to the NEW NOCO genius 3500 which did not even recognize that a battery was hooked up...talk about Dead!
