Battery charger question

We have a 12 volt electric toy car for the grandkids. The car will run for about an hour and half to two hours on a charge. It takes 10-12 hours to recharge the battery (!). This is, of course, unacceptable to the grandkids

The charger is a "wall wart" with the following on it...

Input: 100-240V, 0.8A
Output:12V, 1.0A

I'm looking for a way to recharge it faster. I have a 12V car battery recharger - can i use that somehow?

I know i could get a second battery but they are about $60 and i'd rather not spend that at this point.

Any suggestions?

Thanks!

I would use a constant current-constant-voltage charger (CC-CV) or multi stage smart charger if you want to fast charge. They can hit the battery hard for fast charging but sense when the battery is nearing full and back off on the charging to avoid over charging. But, by the time you factor the cost of a good charger a second battery isn't such a bad idea.
