How to Store a Golf Cart in Summer Heat
Keep it out of direct sun, keep the battery charged, and check the tires before it sits for any length of time.
Shade, charge, and airflow matter most
Heat damages a golf cart mostly through the battery and the tires. Park it somewhere shaded, even a carport or a tarp canopy, because direct sun raises the temperature inside the cart well above the air temperature outside, and that heat is what dries out seals, fades vinyl, and shortens battery life.
If it will sit for more than a few days, check the battery water level if it's a lead acid battery, and keep it on a trickle charger or maintainer rather than leaving it fully charged or fully drained. A cart that sits unused in heat with a neglected battery is the most common way people end up needing a replacement before they expected to.
What kind of battery it has
A lead acid battery needs more attention in heat than a lithium one. Heat speeds up water loss in lead acid cells, so check the water level more often in summer than you would in cooler months, and top it off with distilled water if the plates are exposed.
Lithium batteries handle heat better and don't need water checks, but they still shouldn't sit at a full charge in high heat for weeks at a time. Check what the manufacturer recommends for storage charge level, since it's usually lower than a full charge.
Either way, avoid charging the cart in direct sun or in an enclosed space that traps heat, like a metal shed at midday. The charger itself can overheat too.
Where and how it's parked
Tires lose air faster in heat, and a cart that sits in one spot for weeks can develop flat spots on the tires where the weight rests. Check tire pressure before any stretch of storage, and move the cart or roll it forward and back occasionally if it's going to sit for a long time.
A cover helps, but only if it breathes. A tight plastic tarp traps moisture underneath and can do more harm than good, especially to the seats and dashboard. Look for a cover made for the purpose, or at least one that isn't sealed flush against the body.
If the cart is stored outside rather than in a garage or carport, check it more often. Afternoon sun on asphalt or concrete radiates heat back up into the cart from underneath, which is easy to overlook.
Questions people ask about this
Does extreme heat affect golf cart insurance coverage?
Heat damage itself usually isn't a covered event under most policies, since it's treated as a maintenance issue rather than a sudden loss. Coverage generally applies to things like theft, collision, or weather events such as hail or flooding. Check your policy's language on what's excluded as wear and tear, since that's usually where heat-related battery or tire damage falls.
Can I leave my golf cart plugged in all summer?
It depends on the charger and the battery type. A smart charger or maintainer that stops charging once the battery is full is generally safe to leave connected, but an older charger without that feature can overcharge the battery, especially in heat. Check the charger's manual for whether it's rated for continuous or trickle use.
Should I remove the battery for summer storage?
You don't need to remove it if the cart is being used occasionally or checked on regularly. Removing the battery is more common for long term storage over winter. For summer heat, the bigger concern is keeping it charged correctly and out of direct sun, not removal.
Will summer heat void my golf cart warranty?
A warranty generally covers defects in parts or workmanship, not damage from heat exposure or improper storage. Check your warranty documents for any exclusions related to environmental damage or failure to follow the manufacturer's storage guidance, since that's where a claim could be denied.
Does a golf cart need insurance if it's just sitting in storage?
That depends on your state and your policy. Some insurers let you reduce coverage to comprehensive only while a cart is stored and not driven, which can lower the cost while still covering theft or fire. Ask your insurer directly what storage options they offer and what documentation they need.
If your golf cart insurance is up for renewal, it's worth seeing what else is out there before you pay another season's premium.
This week, check your battery's water level or charge percentage depending on the type, and park the cart somewhere shaded if it isn't already. Check tire pressure and look underneath for any pooling water or debris that heat and humidity can make worse. Pull out your insurance policy and read what it says about storage, exclusions, and wear and tear, so you know what's actually covered if something does go wrong. If you have questions about what your policy covers while the cart is parked, call your insurer and ask directly rather than assuming.
