I've got a 2007 model DRZ400SM. The original battery that I bought the bike with was a couple of years old and wasn't holding charge because I mainly do short trips and it was getting to the point that I had to jump start it off a car a couple of times. (The guy that I bought it from had it on a trickle charger) So I bought a brand new battery from Bike Biz and they couriered it over. Got it charged, installed it, rode it once then a week later went to ride again and bike was completely dead. Not even a glimmer of light on the speedo. So I bought a charger (an automatic Battery Fighter charger/trickle style) of my own and it will not charge the battery at all. the ERROR light keeps blinking at me the rude bastard. Thought the charger must have been rooted so went and bought ANOTHER one of a different brand because I'm so pinging for a ride. And this charger doesn't even turn on when it's connected to the battery. I called my mate Marty who came over and stuck his multimeter on the battery terminals an it showed 2.7volts instead of 12 or 13. In his words "Your battery is f*cked". Even though its brand new?! So from a fully charged battery - how long can you go without riding to still start OK? Marty was in America for a month then his FZ6 started straight away. Yet after 1 week my bike is flat as. And what are my chances of getting battery replaced by Bike Biz?
