did you buy an after market battery or another sunl! get a good one for 25-35$$ and be done. it was irritating the crap out of me when i had to do this all the time!!

 

Hope you didnt get another stock battery.My RedCat 110 did the same thing so I bought one from Advance Auto Parts($23.88+tax) and it hasnt gave me a lick of trouble.

If you got at an auto parts store or Wal-Mart,some where like that,I would just go exchange it and not bother having it checked.Just tell'em it aint holdin a charge and they will exchange it hassle free.Or they should.

I also bought a Shuemaker(?) battery tender for mine,so I dont have to worry about overcharging.

 

One thing I noticed with mine is that at an idle, it produces no charge to the battery whatsoever. Once you give it about some throttle it will start charging. So basically while riding the quad, the battery will be okay, but if you let it sit and idle with any lights on the battery will start to drain.
