Winterizing a golf cart involves cleaning, charging the battery to 50-70%, inflating tires, and storing in a dry, temperature-controlled space. Use a breathable cover to prevent moisture buildup and disconnect the battery to avoid parasitic drain. For lithium-ion models, maintain 50% charge and use a storage-mode charger. Pro Tip: Add fuel stabilizer if storing gas-powered carts over 90 days.How Long Can a Golf Cart Sit Unused?
What are the essential steps to winterize a golf cart?
Key steps include cleaning the chassis, stabilizing the battery, and elevating tires. Remove debris from undercarriage seams to prevent corrosion, and apply dielectric grease to electrical connections. Lithium batteries need partial charge (50–60%), while lead-acid types require full charging monthly.
Start by pressure-washing the cart to eliminate dirt and salts that accelerate rust. For batteries, disconnect terminals and store at 10–25°C. Lead-acid units lose 3–5% charge monthly—use a smart maintenance charger to prevent sulfation. Tires inflated to OEM PSI (often 18–22) avoid sidewall cracks. Practically speaking, a lithium battery stored at 0°C retains 97% capacity over winter versus 88% at 30°C. Pro Tip: Place mothballs near wheels to deter rodents. For example, a 48V lead-acid pack left uncharged for 4 months may permanently lose 20% capacity.

How should batteries be maintained during storage?
Batteries require temperature-controlled environments and charge management. Lithium systems benefit from partial charging, while lead-acid needs periodic top-ups. Always disconnect cables to prevent phantom loads from GPS or security systems.
Lead-acid batteries self-discharge 5–10% monthly. Use a float charger maintaining 13.1–13.4V (for 12V units) to counteract this. Lithium batteries, however, tolerate storage at 50% charge with BMS sleep modes. Why does this matter? A 48V lithium pack at 30% charge can suffer plating below -10°C, reducing lifespan. Storage above 40°C increases degradation by 3x. Pro Tip: For flooded lead-acid, check electrolyte levels monthly—distilled water only. An example: Storing a lithium cart battery at 50% charge and 15°C preserves 99% capacity after 6 months versus 85% at full charge.

Why is tire care critical for long-term storage?
Tires develop flat spots if left stationary, especially under-inflated. Keep them at OEM pressure or elevate the cart on jack stands. Rotate tires monthly to distribute weight evenly.
Golf cart tires rated for 18–22 PSI can lose 1–2 PSI monthly in cold storage. Permanent flat spots start forming after 60 days of immobility. Consider using tire cradles or placing plywood under wheels to reduce ground hardness. For context, a 500-lb cart exerts ~125 lbs per tire—enough to deform sidewalls. Pro Tip: Apply UV-protectant spray on tire walls if stored near windows.
| Issue | Under-Inflated | Properly Inflated |
|---|---|---|
| Flat Spot Risk | High (60–90 days) | Low (120+ days) |
| Sidewall Cracking | Likely | Rare |

FAQs
No—use breathable fabric covers. Plastic traps moisture, accelerating mold and corrosion, especially on brake components.
Should I start my gas golf cart monthly during storage?
Yes, idle it for 15 minutes to circulate oil and prevent carburetor clogging. Add stabilizer to fuel first.
How often check tire pressure in storage?
Every 60 days. Temperature drops reduce PSI—reinflate to OEM specs to avoid sidewall damage.
