Dead Battery?

8 posts in this topic

So a few weeks ago I went riding and when I got home I put my 06' WR 450 away and forgot to turn it off. Next time out the battery was dead and I wasnt even close to get it started. I decided to jump start the bike by connecting it to the car and it turned on right away. :mad: I then hear that it is not a good idea to have connect it to the car because of the high amps a car battery has. A week later, battery is dead again so I buy a charger this time to charge. After fully charging the battery and trying to start my bike again nothing happens. :mad: Does anyone think I could have damaged the battery or electrical system by having had connect it to a car battery??

Nope, it was damaged by being flat(discharged) for too long....that's the quickest way to kill any battery.

As long as the car is not running, there is no problem using it to jump a bike or any other 12v system. Both have the same voltage, the amount of power used is determined by the load (the starter). A car battery will just crank a lot longer. Better to kill your battery than overheat the starter.

get yourself a battery tender , or the battery tender jr. after riding, you just plug it in. it charges the battery and turns itself off when the battery is done. it comes with a pig tail that you can attach to the battery, and hide under the plastic.

Was this because you forgot to turn the switch off again. I ask because I have done that a few times. Is it just me that thinks this ignition switch is unnessasary. None of my friends bikes have switches. Does anyone know if it can be bypassed? Yes, I am absent minded.

I have killed the battery a few times but after I charge it up it is runs great.

perhaps when the voltage droped on the start system the amprage went up

this would have blown a fuse under the seat

Where is a good place to pick up a battery cheap? Dealer wants my first born in exchange! On some days I think I would be getting the better deal!!
