I bought the F150 Monster traction for my 2y.o. at Christmas and hes had what I consider (noob) to be little to moderate time on the truck. I bought the Quick charger thats supposed to condition the battery yet its showing a bad battery signal now. The truck has never been run dead and was working at what seemed to be full strength the day before. When I got home from work my daughter told me the battery was dead and I was really surprised. I bought a new battery today and the charger and truck work great. How often should these die?

Thanks for your help

How long a battery will last really depends on how well it is maintained, including before you buy it. If that vehicle/battery sat on the shelf for a long time, it may have been 'bad' when you got it, but it should still be under warranty. A charger/maintainer (as you mentioned) is the best way to get the most life from a battery. Just keep it connected to the battery as much as possible, and try not to let the battery get drained too far, and it should last for several years.

the average time is about 45 mins to an hour, but there are many variables to play into here. rider weight, ground slope, grass vs. pavement, 1st or 2nd gear.... and the list goes on.

The last few days, JD has been going farther down a trail near us.
I retraced our route, he made it over three miles on his modified Enforcer using the 14AH Powertron battery. But it was really slow the last block home.

So you should get at least two miles out of a stock battery.

One note, the "automatic" chargers refuse to charge batteries that are dead beyond a certain point. I've found that if you use the stock "dumb" charger you can sometimes bring these batteries back to life because they'll attempt to charge no matter what the condition of the battery is.

That's a great point! I actually read in the documentation for one of the high-frequency chargers that if the voltage is to low for microprocessor logic, you can try using a 'dumb' charger to get it just high enough for the smart charger to accept it.

Kinda makes you wonder why they didn't just make the smart charger a little smarter?
