Our granddaughter loves this remote control car. The car has a battery compartment on the bottom that you need to remove 2 screws to pull out the battery, the car comes with a USB charger you can plug the battery into to recharge. The remote works great, it did require two triple-a batteries which are not included. The white globe on top of the car is the water reservoir for the cannon, it simply unscrews, but then you must hold the car upside down to screw it in so your water does not all spill. I would recommend this remote control car....
