Remote control car and scooter, excellent battery charging but needs a battery

The car is clean, I only used it for a few days, I don't need it anymore so I stored it, later it didn't work, needs a new battery. The remote and batteries are working, the gas pedal is very clean, and the scooter is also clean. All for 150 SAR. My location is Riyadh / Al-Shifa, Bader District
