Battery lasts at least 4 hours (when new). The battery life will shorten over time, best case scenario it will last you a couple years. The instructions say it takes 18 hours to charge, but there is no light indicator, so the only way to know if's full is to check with a battery tester or multimeter. Do not overcharge the battery (i.e., don't leave it plugged in for days at a time) - this AC adapter/charger is not a trickle charger and could fry your battery to overcharge.
The Power Wheels Jeep Wrangler from Fisher-Price promotes a basic understanding of cause & effect as kids learn how to power the vehicle and make it go forward, back, steer, stop and start it up again. This easy-to-drive 4-wheeler helps build gross motor skills as kids cruise around the yard, on the sidewalk, or down the driveway – and stop safely when they take their foot off the pedal. Beginners start at a fun but safe 2.5 mph in forward and reverse – and when they’re ready, adults can move them up to 5 mph in the forward direction by removing the high speed lock-out.
