How to Store an Electric Golf Cart for Winter
To store an electric golf cart for winter, clean and dry it, prepare the batteries for their chemistry, shut down unnecessary electrical loads, and protect the cart in a dry storage location. Flooded lead-acid, sealed lead-acid, and lithium batteries need different preparation, so there is no universal “leave it plugged in” rule. The process below covers battery care, cold-weather charging, outdoor protection, and the checks that help your cart start reliably in spring.
Why Golf Cart Battery Type Matters
Winter storage is more than parking the cart under a cover. Batteries can lose charge while sitting, and accessories or onboard electronics may continue drawing power after you remove the key.
Lead-acid batteries need to stay charged to limit sulfation, which reduces their ability to hold a charge. Lithium batteries have different storage-charge requirements depending on the manufacturer, and their battery management system may still consume power during storage.
Identify the batteries actually installed in your cart. A cart converted to lithium no longer follows every battery instruction in its original lead-acid owner’s handbook.
How to Prepare an Electric Golf Cart for Winter Storage
Use the battery label to choose the correct preparation, not the cart’s age, appearance, or voltage alone.
| Battery Type | How to Identify It | Main Preparation Decision |
|---|---|---|
| Flooded lead-acid | Label identifies flooded or wet-cell construction; service caps provide access to electrolyte | Check electrolyte and plan charge maintenance |
| Sealed lead-acid, including AGM and gel | Check the battery label. | Do not open or add water; use the correct charging profile |
| Lithium | Check the battery label for lithium. | Confirm its storage-charge target, shutdown procedure, and cold-charging limits |
Step 1: Identify the Battery and Charger
- Record the battery brand, model, and chemistry. Photograph the labels so you can find the correct storage instructions without repeatedly opening the compartment.
- Confirm that the charger matches both the pack voltage and battery chemistry. A charger intended for the cart’s original batteries may not suit a replacement lithium pack.
- Establish whether the system is designed to remain connected to an approved storage charger, be charged periodically, or be switched into a storage mode.
For a converted cart, the battery manufacturer’s instructions govern battery care, while the cart handbook still matters for controls, parking, lifting, and support points.
Step 2: Choose a Dry, Accessible Storage Location
- Choose an indoor location when possible, protected from precipitation, standing water, and unnecessary temperature extremes. Leave enough access to inspect the batteries and connect the charger safely.
- Check the battery’s permitted storage temperatures against the coldest conditions the location is likely to reach.
- Make sure any charging area has ventilation and a suitable electrical supply. Charging lead-acid batteries can release hydrogen, so keep flames, sparks, and other ignition sources away.
For Trojan lithium batteries, the ideal winter storage range is 32°F to 80°F. When arranging a climate-controlled space for winter recharging, Trojan also identifies 32°F to 85°F as a range that avoids the below-freezing charging issue for its lithium batteries.
Those are Trojan’s figures, not universal limits for every golf-cart battery.
An unheated garage can still be suitable. The important questions are whether it stays within the battery’s storage limits and whether the battery can be brought to a permitted temperature before charging.
Step 3: Clean the Cart and Inspect the Batteries
- Remove food, trash, wet towels, and other items that can attract pests or retain moisture. Clean the body, floor, seats, and accessible underbody, then let everything dry before covering the cart.
- Wipe dirt from battery exteriors with a lightly damp cloth and dry the surfaces. Keep service caps closed, and do not pressure-wash the battery compartment or spray electrical components.
- Inspect the batteries, cables, charger plug, and charging receptacle. Have cracked cases, leaks, swelling, damaged insulation, loose connections, or heavy corrosion corrected before storage or charging.
- On flooded lead-acid batteries, check the electrolyte before charging. If the plates are exposed, add only enough distilled water to cover them; complete the final fill after charging.
Wear eye protection and acid-resistant gloves when servicing flooded batteries, and remove metal jewelry. Never bridge battery terminals with a tool. If cleaning requires removing cables or working on badly corroded connections, use a qualified golf-cart technician rather than improvising an isolation procedure.
Step 4: Charge and Finish Preparing the Batteries
- Check a cold lithium battery’s cell temperature before charging. For Trojan lithium batteries, cells below 32°F are too cold for normal charging, and suitable cold-charge protection will prevent it. For other lithium batteries, use the pack’s specified charging-temperature limits rather than assuming Trojan’s cutoff applies. Room temperature and cell temperature are not necessarily equal: a cold-soaked battery can remain cold after the surrounding air warms. Move the cart to an appropriate warmer location and allow the cells to warm before charging. Do not bypass a low-temperature charging lockout or apply concentrated heat. Driving can warm the cells in a Trojan lithium pack, provided the battery has enough charge and conditions are safe. Before using that option, check the operating limits: Trojan’s rated operating range for its lithium batteries is -4°F to 140°F (-20°C to 60°C). That is an operating range, not a charging range or an ideal storage target, and should be confirmed against your specific Trojan battery specifications.
- Fully charge lead-acid batteries with their compatible charger. Let the charger complete its normal cycle rather than relying on a fixed number of charging hours. Required charging time changes with battery condition, charger output, and starting charge.
- Finish watering flooded batteries after charging. Bring the electrolyte to the battery manufacturer’s fill mark using distilled water. Do not fill to the brim, because electrolyte expands during charging. Secure the caps and leave the battery tops clean and dry.
- Use the lithium manufacturer’s storage-charge target. For Trojan lithium batteries, charge to 100% before long-term storage, then disconnect the charger, following Trojan Battery’s winter-storage guidance. Do not leave that charger connected needlessly throughout winter.
Other lithium packs may specify a different storage charge.
Step 5: Shut Down the Cart and Unnecessary Loads
Turning off the key is not the same as isolating the battery.
- Shut down unnecessary electrical loads before storage. Check for aftermarket accessories that may have a separate supply or remain powered continuously.
- Use the battery’s specified storage or shutdown mode. If a Trojan lithium battery remains installed, put it in storage mode and set the cart to TOW mode, including when the cart must stay outside.
- Leave the charging connection in the state required by the installed battery-and-charger system. A generic trickle charger is not automatically a suitable substitute.
Disconnecting the charger and disconnecting battery cables are different actions. Physical cable disconnection is appropriate only when the cart or battery procedure calls for it. If that procedure requires pack isolation and you cannot confidently identify the correct connections, have a technician prepare the cart.
TOW mode can reduce electrical drain, but it is not proof that every accessory is disconnected or that the battery has stopped self-discharging.
Step 6: Protect the Tires and Secure the Cart
- Inflate the tires to the cart or tire manufacturer’s specified operating pressure. Do not add extra pressure simply because the cart will be parked.
- Park on a firm, level surface and secure the cart against rolling with appropriate wheel chocks. Use the cart manufacturer’s long-term parking-brake procedure rather than assuming the brake should always be left engaged or released.
- Once the cart is dry, fit a suitable storage cover without obstructing any ventilation needed during charging.
- Record the storage date, battery charge indication, and shutdown settings. Arrange access for winter inspections before leaving the cart unattended.
The finished cart should be clean, dry, secured against movement, and prepared for the charging arrangement its batteries actually require.
Outdoor Golf Cart Storage in Winter
You can store an electric golf cart outside, but weather protection does not replace battery preparation. A cover keeps precipitation off the cart; it does not keep the battery warm.
- Choose a sheltered, well-drained location. Avoid low spots where water collects and places exposed to roof runoff or falling ice. If weather conditions make the location unsuitable, move the cart or arrange suitable storage for the battery.
- Protect the tires and support the cart safely. An outdoor winter-storage setup can include keeping the cart raised on blocks, but only with an approved lifting and support arrangement. Use the cart’s designated support points and purpose-made, load-rated support blocks or stands, not loose masonry blocks. Never leave the cart supported by a jack alone.
- Fit a waterproof cover after the cart dries. Secure it against wind and arrange it so water sheds rather than pools. Avoid sealing a wet cart beneath a tarp; trapped moisture encourages corrosion and mildew.
- Keep charging equipment dry and properly ventilated. Do not operate a charger beneath a tightly sealed cover or leave indoor-only charging equipment exposed to the weather.
- Leave inspection access. You should be able to check the battery compartment, supports, tires, and cover without dismantling the entire storage setup.
If you lack approved lifting equipment, leave the cart on its correctly inflated tires and inspect them during storage rather than improvising supports. Have a dealer handle battery removal if a warmer location is necessary and you are unfamiliar with safely isolating and moving the pack.
How to Check Golf Cart Batteries During Winter
For Trojan lithium batteries, check the charge level in the Trojan BMS app once a month or so and recharge as needed. Confirm any model-specific instructions in the battery documentation; the app shows the actual state of charge rather than an assumed amount of winter discharge.
Trojan quotes typical drain for its stored lithium batteries as “1 to 3 amps per month,” with greater losses in extreme cold. That wording is not a usable monthly capacity-loss specification: amps measure current, not capacity lost over a month. Confirm standby consumption in the battery documentation rather than calculating storage time from Trojan’s typical drain.
For other battery systems, use an inspection schedule and recharge threshold suited to the installed batteries and charger. Do not apply a lithium app reading, voltage threshold, or maintenance schedule to a different chemistry.
At each storage check:
- Read the charge indication. Use the battery’s approved app, gauge, or test method. A substantial unexpected drop warrants checking for an accessory load or battery fault.
- Inspect the battery compartment. Look for moisture, corrosion, loose connections, case damage, or unusual odors.
- Check the cart’s protection. Make sure the cover remains secure, tires are not visibly losing air, and any supports remain stable.
- Recharge when required. For Trojan lithium, do not attempt normal charging with cells below 32°F. Warm the battery into its permitted charging range first.
- Restore the storage setup after charging. For Trojan lithium, disconnect the charger at 100%, restore the battery’s storage mode, and return the cart to TOW mode. For another system, restore its specified shutdown and charger-connection state.
Do not keep retrying a charger against a damaged battery or repeatedly override a fault. If a pack will not wake or accept a charge, use the manufacturer’s recovery procedure or have it checked by a qualified technician.
How to Bring a Golf Cart Out of Winter Storage
Before the first spring round, inspect the cart rather than immediately connecting the charger and driving away.
- Remove the cover and look for water intrusion, rodent damage, loose wiring, or damaged charger connections. Do not power up a cart with visibly damaged electrical components.
- If the cart was raised, lower it using its approved lifting procedure and equipment. Restore tire pressures to the specified operating values.
- Check battery condition and, for flooded lead-acid batteries, electrolyte level. If battery cables were disconnected for storage, have them restored using the approved connection sequence and terminal-tightening specifications.
- Complete the manufacturer’s return-to-service charge. Finish any required post-charge watering and secure all service caps.
- Restore the battery and cart to their normal operating settings. Check steering, brakes, lights, and other controls before leaving the storage area.
- Take a low-speed test drive in a clear area, then check for warning messages, abnormal noises, hot connections, or an unexpectedly rapid drop in charge.
Keep the storage notes with the cart’s records. Once the inspection and test drive are satisfactory, the cart is ready to return to normal use.
Frequently Asked Questions
Are Golf Cart Batteries OK at 45°F During Storage?
Yes, 45°F is generally a suitable storage temperature for golf-cart batteries in good condition. For Trojan lithium batteries, it falls within the manufacturer’s ideal storage range of 32°F to 80°F. For lead-acid batteries, maintaining charge and preventing unwanted electrical drain remain important even at a moderate storage temperature.
Can I Store Trojan Golf Cart Batteries All Winter Without Charging?
Do not assume they can go an entire winter without a recharge; Trojan makes both lead-acid and lithium batteries, and the storage procedure differs. Trojan lithium batteries should enter storage at 100%, with the charger disconnected afterward, and their charge should be checked in the Trojan BMS app once a month or so. Whether a top-up is necessary depends on actual charge loss, so arrange inspection access even if you expect the cart to remain unused.
Will Golf Cart Batteries Freeze in Winter?
Lead-acid batteries can freeze, especially when discharged; a fully charged battery is substantially more resistant to freezing than a depleted one. Do not charge or use a battery that appears frozen, swollen, cracked, or leaking: have it assessed first. For lithium batteries, use the pack’s specified storage-temperature limits rather than applying a lead-acid freezing rule.
Is it safe to keep a lithium golf-cart battery in cold weather?
For winter storage, keep a Trojan lithium battery between 32°F and 80°F whenever possible. Do not attempt to charge it when its cells are below 32°F; batteries with suitable safety features will prevent charging below that temperature.
What are practical ways to store a golf cart for winter?
Use an indoor storage space when one is available. If the cart must remain outdoors, let it dry completely before fitting a waterproof cover and completing its winter battery preparation.
