## KRONOBAT Toys: AGM replacement batteries for kids' ride-on cars

The **KRONOBAT Toys** range comprises sealed AGM lead-acid batteries (VRLA), maintenance-free and leak-proof, designed specifically to replace the original battery in kids' electric ride-on cars, toy motorbikes and battery-powered karts once it loses range or stops taking a charge.

### How to choose your Kronobat toy battery

Check the voltage (6V or 12V) and capacity (Ah) on the toy's original battery label: a different voltage can damage the motor, while more Ah than the original only adds play time. Use the [comparison tool](/gb/comparator) to find the equivalent Kronobat model by voltage and capacity.

## Frequently asked questions about Kronobat toy batteries

### **How do I know if I need a 6V or 12V battery?**

Check the label on the original battery of the kids' car or electric motorbike: most small single-seat models use 6V, while two-seat or more powerful ones use 12V.

### **Is it compatible with any brand of kids' electric car?**

Yes, as long as the voltage, a similar or higher capacity (Ah) and the battery compartment dimensions match, regardless of the toy's brand.

### **How long does a Kronobat toy battery last?**

With normal use and charging, this type of sealed AGM battery usually lasts several play seasons before losing capacity.

### **Can I fit a battery with more Ah for longer play time?**

Yes, as long as the voltage matches and the battery physically fits the toy's compartment, more Ah means more play time per charge.
