My 03 DRZ400E finally had the ORIGINAL battery go bad seven months ago, went to my local Honday/Yahama/KTM dealer and bought a Bike Master battery from them. It was fine the first few months now winter set just n and even though my bikes are in a heated building (set at 50* Fahrenheit) it lost charge. I used my battery tender Jr and it was fine again...Just forward one month till today, it was a nice 58* day so me and the kids went riding. At 8am I checked my bike and no light battery DEAD, so I used my battery charger and let it charge till 11am when I disconnect the charger hooked the battery back and loaded the bikes up. So we drive to the pit and I get the kids up and running go to fire up the DRZ and NOTHING no head light or anything!! I didn't have my multi meter so I was screwed....tried bumping the motor by pushing the bike and dumping the clutch but that was a no go. A younger guy stopped with a 400ex and said he would pull me so I said ok, first attempt bike back fired, second attempt it started but was running like shit then quit. Third attempt nothing, fourth attempt nothing.... so i started to investigate and the 10amp fuse had blow, i installed the backup (good thinking suzuki) and tried attempt number five. Bike started and was running like DOG tried to drive around I smelled burnt rubber smell! Luckily I had the battery panel off and I seen the battery was smoking!!! Hit the kill button and QUICKLY removed the battery wires and threw the battery on the ground. Checked over the bike and no burnt wires or damage BUT the 10amp backup fuse had blown again, the kid said let's see if it will start, so we bumped it again and she fired right up and ran BEAUTIFUL like she always does. So from 11:45 to 6pm I ran her all day, never shut her off, she was running like a bear all day. SO I'm assuming the battery shorted out internally I'm hoping? Second what's a great battery that will last like the original did from 2003?
