How to Store Power Wheels Over Winter

Every spring, a predictable thing happens in Power Wheels households across the northern hemisphere: parents pull the ride-on out of the garage or shed, plug in the charger, and find that the battery is completely dead — and this time, it won't come back. Four months of winter storage killed it.

This doesn't have to happen. Lead-acid batteries fail when stored in a discharged state. They don't gradually recover over spring; they sulfate, lose capacity permanently, and need to be replaced. A $35–$50 battery that should last 2–3 years dies at month 5 because nobody charged it before putting it away.

Proper winter storage takes about 30 minutes of work in the fall and five minutes of attention every six weeks. That's it. Here's what to do.

Before You Store: The Fall Checklist

Clean the vehicle before storing it. Not deep detailing — just hose it off, dry it, and remove any mud or debris from the wheel wells and undercarriage. Debris left on the vehicle over winter attracts moisture and can cause surface corrosion on plastic and metal parts.

Check for any mechanical issues that were minor during the season: a wheel that wobbles slightly, a connector that was intermittent, a gear that occasionally grinds. Minor problems get worse over 4–5 months of temperature cycling. Fix them now rather than discovering them on the first warm Saturday of spring.

Remove the battery or leave it in — either is fine, but if you remove it, label which connector is positive (red) and keep the connectors from touching metal surfaces.

The Critical Step: Battery Charge Level

Store the battery at full charge. This is the most important single thing you will do. A fully charged 12V lead-acid battery reads 12.6V to 12.8V at the terminals. Check it with a multimeter before putting the vehicle away.

If the battery is partially discharged from the last ride of the season, charge it fully before storage. Not "good enough" — fully. 14–18 hours on the stock charger, or until a smart charger indicates complete.

Lead-acid batteries self-discharge slowly over time even when not in use — roughly 1–3% per month under normal conditions. Over 4–5 months of winter storage, a fully charged battery will drop to around 12.0–12.3V. That's fine; it'll charge back up quickly in spring. A battery stored at partial charge can drop below 11V, triggering the sulfation process. Once sulfation begins in earnest, run time is permanently reduced.

Using a Battery Tender for Long Storage

The best solution for winter storage is a smart charger/maintainer like the Battery Tender Plus or NOCO Genius series. These devices charge the battery to full, then switch to a maintenance mode that delivers a small trickle to offset self-discharge — keeping the battery at exactly the right charge level indefinitely.

Plug in the Battery Tender in October, leave it connected to a garage outlet all winter, check it once in January to confirm it's still showing the green "maintenance" light, and unplug it in March. The battery will be at perfect health in spring.

This is not a required purchase, but if you have a toddler who will be using the same ride-on for 2–3 more years, the $40 investment extends the $35–$50 battery life significantly. The math works.

Indoor vs. Outdoor Storage

Indoor storage is better, and for batteries, it's significantly better. Lead-acid batteries lose charge faster in cold temperatures, and extended exposure to freezing temperatures can cause expansion damage to cells. A garage that stays above freezing is fine. A shed that drops to 10°F over January is hard on the battery.

If outdoor storage in cold temperatures is your only option: remove the battery and bring it inside. Leave it on a Battery Tender or at minimum on a shelf in a temperature-controlled space. The vehicle body can handle the cold; the battery shouldn't be frozen.

Covering the Vehicle

Cover the vehicle with a tarp or a dedicated cover. Not for structural protection — plastic handles winter fine — but to keep the seat dry (water sits in seat seams and causes mildew), keep debris and small animals out of the wheel wells and motor areas, and protect the electronics from repeated moisture exposure.

A cheap plastic tarp secured with bungee cords works perfectly well. You don't need a custom-fit cover unless you want one.

Spring Startup: What to Check

Before your child's first ride of the season, run through this list:

Charge the battery fully before use — even if it's been on a Battery Tender all winter, top it off with a full charge cycle.

Test voltage with a multimeter. A healthy battery after winter storage should read 12.4V or above. Below 12V suggests significant degradation; below 11.5V means replacement before the season starts.

Check all wheel connections — spin each wheel by hand and confirm it rolls freely. Debris can jam wheel hubs during storage.

Test the vehicle without a child first — short test run to confirm motor, steering, and reverse all work before loading up a 4-year-old.

Check the foot pedal switch — switches can corrode during storage. If the vehicle hesitates or won't start on the first press, clean the switch contacts with electrical contact cleaner.
