Will This Battery Work in Your Power Wheels?
Not every 6V Power Wheels battery is the same. This one is a 6V, 9.5 Ah battery, so your vehicle must call for that rating. Run this quick check before you buy.
Some 6V Power Wheels models use a smaller 4 Ah blue battery with its own charger, and older vehicles can use different plug styles. Do not judge fit by voltage or battery colour alone. Check your vehicle manual.
