Electric Golf Cart Pre-Storage Checklist: The First Steps

Before you put your golf cart away, do a few checks. This electric golf cart pre-storage checklist helps you. It makes sure you do not forget anything important.

  1. Clean Your Cart Thoroughly:
    • Wash the whole cart. Use mild soap and water.
    • Clean the body, seats, and wheels.
    • Rinse it well. Make sure no soap is left.
    • Dry it completely. Use a soft towel or air dry.
    • Wipe down all surfaces. This stops dirt from sitting on the cart. Dirt can cause scratches or stains.
    • Clean the undercarriage too. Mud and grime can hide there. They can cause rust later.
  2. Inspect Your Cart:
    • Look for any damage. Check the body, frame, and tires.
    • See if any wires are loose. Check for fraying.
    • Look for rust. Small spots can grow big.
    • Check brake lines. Make sure they are not leaking.
    • Note anything that needs fixing. You can fix it now or in spring. Fixing it now might be easier.
  3. Check Tire Pressure:
    • Find the right tire pressure for your cart. It is often on the tire or in the manual.
    • Fill the tires to the correct pressure.
    • You might want to over-inflate them slightly. Add about 5-10 PSI more than normal. This helps prevent flat spots. Flat spots can happen when a cart sits still for a long time.
  4. Lubricate Moving Parts:
    • Use grease on parts that move. This includes suspension points and steering joints.
    • Grease stops rust. It also keeps parts moving smoothly.
    • Check your manual for where to grease.
  5. Remove Valuables and Personal Items:
    • Take out anything you do not want to leave in the cart.
    • This includes golf clubs, towels, and personal items.
    • This keeps them safe. It also stops pests from being attracted to them.

This checklist makes sure your cart is clean and ready. It sets the stage for the next, very important steps.

Golf Cart Battery Winter Care: The Heart of Your Cart

The battery is the most important part of an electric golf cart. It is also the most sensitive to cold. Proper golf cart battery winter care is a must. If you do this right, your batteries will last longer. They will work better next season. Ignoring them can ruin them.

Steps for Optimal Battery Care:

  1. Clean Your Batteries:
    • Disconnect the main negative battery cable first. Use a wrench.
    • Wear safety glasses and gloves. Battery acid can burn.
    • Mix baking soda and water. Make a paste.
    • Apply the paste to battery terminals. Use a wire brush.
    • Scrub away corrosion. This looks like white or green powder.
    • Rinse with clean water. Dry with a clean cloth.
    • Make sure no water gets into the battery cells.
    • After cleaning, put anti-corrosion spray or grease on the terminals. This stops new rust.
  2. Check Water Levels (for Lead-Acid Batteries):
    • If your cart has lead-acid batteries, check the water.
    • The water level should be above the plates. Use distilled water only.
    • Never use tap water. Tap water has minerals. These minerals harm batteries.
    • Fill cells to the right level. It is usually about 1/4 inch below the fill hole.
    • Do this after fully charging the batteries. Charging makes water expand.
  3. Fully Charge Batteries:
    • This is the most important step for winter battery maintenance golf cart.
    • Charge your batteries completely. Use your regular charger.
    • A full charge prevents freezing. A discharged battery can freeze and crack.
    • It also stops sulfation. Sulfation is a build-up on battery plates. It hurts battery life.
  4. Disconnect Batteries (Optional but Recommended):
    • After charging, disconnect the main positive and negative cables.
    • Or, use a battery disconnect switch. This stops all power draw.
    • Even small draws can slowly drain batteries over time.
    • Disconnecting makes sure no power is used.
    • If you cannot disconnect, a smart charger or battery maintainer is a must.
  5. Store Electric Golf Cart Battery Correctly:
    • Ideally, store batteries in a cool, dry place.
    • Avoid extreme heat or cold. A garage or shed is fine.
    • If it gets very cold (below freezing), you might bring batteries indoors.
    • They are heavy, so be careful.
    • Place them on a non-concrete surface. Wood or rubber mats work well. Concrete can slowly drain power.
  6. Maintain Charge During Storage:
    • Even disconnected, batteries lose charge slowly. This is called self-discharge.
    • Check voltage every 4-6 weeks. Use a voltmeter.
    • If the voltage drops below 80% (e.g., for a 48V system, below 46.8V), recharge them.
    • Use a smart charger or battery maintainer. This is the best way.
    • A smart charger turns on and off as needed. It keeps the battery topped off. It prevents overcharging.
    • For a 48V system, target 48V to 50.4V when fully charged. Check individual 8V or 6V batteries too.
Battery Type Winter Care Notes
Lead-Acid Requires water level checks and full charge. Clean terminals. Store in a cool, dry place. Recharge every 4-6 weeks if stored for long periods. A fully charged lead-acid battery is less likely to freeze.
AGM/Gel “Maintenance-free.” No water checks needed. Still needs full charge before storage. Less prone to sulfation. Recharge every 2-3 months. More forgiving in cold.
Lithium (LiFePO4) Most modern. Often have a Battery Management System (BMS). Store at 50-60% charge if possible. Check manufacturer’s instructions. They are less sensitive to freezing when charged, but extreme cold can reduce performance until warmed. Often self-protect in cold.

Proper store electric golf cart battery methods are key. They make sure your cart is ready to go when warm weather returns.

Caring for the Electric Golf Cart Charging System

The charger is just as important as the batteries. Proper winterizing golf cart charging system steps prevent damage. They also ensure the charger works when you need it.

    • Look at the charger case. Is it cracked or damaged?
    • Check for loose screws or parts.
    • Wipe it clean. Remove dust and dirt.
  2. Examine Charging Cables:
    • Check both the AC cord (plugs into wall) and the DC cord (plugs into cart).
    • Look for cuts, fraying, or exposed wires.
    • Make sure the plug that goes into the cart is not bent or corroded.
    • Damaged cables are dangerous. They can also prevent proper charging.
    • Replace any damaged cables.
  3. Store the Charger Properly:
    • Store the charger in a dry place. Keep it away from moisture.
    • Moisture can damage the electronics inside.
    • Keep it off the floor if possible.
    • Roll up the cables neatly. Do not coil them too tightly.
    • Protect it from dust and extreme temperatures. A shelf in a garage is good.
    • Do not leave it plugged in for long periods if not connected to a battery. Some chargers draw a small idle current.
    • If using a smart charger or maintainer, it might stay plugged in for long-term battery care. Follow its instructions.

A well-maintained charging system is vital. It means your batteries get the right power. This keeps them healthy.

Protecting the Golf Cart Electrical System

    • Even better, lift the cart off its tires. Use jack stands. Place them under the frame.
    • This takes all weight off the tires. It stops flat spots completely.
    • If you cannot lift it, move the cart a few feet every month. This changes where the tires rest.
  2. Brake System:
    • Do not engage the parking brake fully. If left on for months, it can seize.
    • If your cart is on a level surface, simply block the wheels. Use wheel chocks.
    • If you must use the parking brake, engage it lightly. Or, release it and re-engage every few weeks.
  3. Body and Frame Protection:
    • After washing, apply a coat of wax to the body. This protects the paint. It adds a barrier against moisture.
    • Check the frame for rust. If you see rust, clean it. Then apply a rust-inhibiting primer and paint.
    • Lubricate all hinges and moving parts. Use a spray lubricant.
    • This stops squeaks and ensures smooth operation.
  4. Fluid Levels (if applicable):
    • Some electric carts have brake fluid. Check the level.
    • Make sure it is at the correct mark. Top it off if needed.
    • Check differential fluid if your cart has a sealed differential. Consult your manual.
  5. Critter Prevention:
    • Mice and other pests love golf carts. They chew wires and build nests.
    • Block any small openings. Use steel wool or mesh screens.
    • Place mothballs or dryer sheets in the cart. Pests do not like these smells.
    • A good golf cart cover also helps keep pests out.
  6. Cover Your Cart:
    • Use a breathable golf cart cover.
    • Do not use a plastic tarp. A tarp can trap moisture. This leads to mold and rust.
