Best 24V ride-on batteries

24V is the two-seater and UTV class, and the batteries reflect it: heavier, more expensive, and in many cases supplied as a proprietary wired pack rather than a bare cell with terminals. That makes compatibility a bigger question than at 12V, and the cost of getting it wrong higher.

A 12V 12Ah SLA is under $40. A 24V 7Ah pack is over $100, and a 24V 12Ah lithium is around $140. At those prices, the common 12V strategy of buying a second battery for continuous play stops making obvious sense — a spare 24V pack costs a meaningful share of a budget vehicle.

The better move at 24V is usually to buy the largest capacity you can in a single pack rather than two smaller ones. See run time and charging.

Vehicles in our registry ship with 5Ah, 7Ah, 9Ah and 10Ah at 24V. 7Ah is the most common on two-seaters, and it is the figure the run time is usually quoted against.

Going to 12Ah is roughly 70% more run time, which on a 24V vehicle matters more than it sounds: four motors draw a lot of current, and grass costs another third. A 24V two-seater carrying two children across a lawn will manage well under an hour on 7Ah.

As at 12V, capacity can go up but never down, and the pack has to physically fit. 24V packs are larger and heavier, so measure the tray and check how it is retained before ordering. See ride-on battery upgrades.

The weight argument is larger here. A 24V 12Ah lead-acid pack would be genuinely heavy — enough to affect how the vehicle handles and how easily an adult can lift it out to charge. The lithium equivalent is substantially lighter at the same capacity.

Add faster charging and tolerance of partial charges, and lithium is the better technical answer at 24V even though it costs more. The constraint is that it needs its own charger, and the lead-acid charger that came with the vehicle must not be used on it.

More 24V vehicles use proprietary wired packs than 12V ones do, which means “a 24V 7Ah battery” is not necessarily enough information. Two of the packs here state named compatibility — one for Power Wheels, kids’ cars and UTVs generally, one specifically for Kid Trax 24V vehicles — and that is what to look for.

For Peg Perego 24V vehicles, the genuine charger carries a real part number and is the only safe answer. See replacement parts by brand.
