Salt, Sand and Storm Season: A Brunswick County Golf Cart Maintenance Calendar

September 16, 2026

After “how much”, the most common question is what should actually be done to this cart, and when. Here is the answer for a barrier island and the towns behind it. The short version: water flooded batteries every two to four weeks from May through September, clean and coat the terminals on a schedule rather than when something fails, check brakes and tires annually because of the sand, get the cart storm-ready before June, and load-test the pack in the autumn rather than discovering it in January.

The long version follows, with the reasons, because a maintenance list you understand is a maintenance list you will actually follow.

The four things that wear out a cart here

Salt air. This is the one that separates Brunswick County from an inland market, and it works continuously whether the cart moves or not. Salt-laden humid air corrodes battery terminals and cable lugs, charge port pins, brake cables and hardware, lighting grounds and connectors, and the fasteners holding it all together. The mechanism is worth understanding once: corrosion at a connection is electrical resistance, and resistance in a circuit carrying several hundred amps produces heat and voltage drop. That is why a corroded terminal does not announce itself as corrosion. It announces itself as a cart that clicks and will not move, cuts out under load, or seems to have lost half its range.

Sand. It rides in on the tires and settles into brake drums, wheel bearings and pedal linkages, where it behaves like grinding paste. The tell is a dry gritty sound rather than a squeal, and shoe wear that arrives earlier than you expected. A cart that lives on sandy streets needs brakes and tires looked at every year, not every third year.

Heat and humidity. Long hot summers evaporate electrolyte out of flooded lead-acid cells. Plates exposed to air lose capacity permanently, and no charger recovers it. Humidity keeps every brass and copper contact slowly oxidizing year round, including inside a closed garage.

Sitting. A large share of carts here belong to houses occupied part of the year. A flooded pack left partly discharged sulfates, and hardened sulfation is permanent capacity loss. Sitting badly is harder on a pack than driving hard is.

March and April: pollen, and the first look of the year

Pine pollen coats everything here in spring, and it is not only cosmetic. On battery tops it mixes with humidity into a mildly conductive film that bridges terminals, slowly self-discharges the pack and accelerates corrosion. In charger and controller vents it blocks airflow, which sets up the thermal shutdowns that turn up in July.

Do not fight it while it is still falling. Once it has settled:

Wash the battery tops with a baking soda solution, rinse, dry, then clean and coat the terminals.
Blow out the charger and controller vents.
Check tire pressure cold. Most cart tires want roughly 18 to 22 psi. Underinflated tires flex, run hot and wear their shoulders, and sand makes that worse.
Book the annual service if you only do one a year. This is the one to keep.

May: watering season starts

From now until the end of September, water a flooded pack every two to four weeks. The rules that matter:

Distilled water only. Tap water carries minerals that poison plates.
After charging, never before. Charging raises the electrolyte level, and topping up first makes it overflow.
Never above the fill ring. More is not better.
Never let plates sit exposed. That damage is permanent.

If the cart is a daily driver, watering is closer to every two weeks than every four, because a hard-cycled pack runs its water down faster.

June through November: storm season

Hurricane season runs 1 June to 30 November, and a tropical system does not have to make landfall to put salt spray, wind-driven rain and standing water where you would rather it were not.

Before the season:

Know where the cart goes if a storm is coming, and make sure it is somewhere it will not stand in water. Batteries and salt water are a bad combination and a submerged cart is frequently a total loss.
Make sure the pack is healthy and charged. A cart is useful after a storm, and only if it starts.
Photograph the cart for insurance while it is intact.

After a system passes:

Look at the terminals before you turn anything on.
Look at the charge port for water intrusion.
Roll test for a brake that seized while the cart sat wet.
If the cart stood in salt water at any depth, do not charge it. Call someone. Charging a flooded electrical system is how a bad day becomes a fire.

July and August: heat

The hottest weeks are when marginal things fail, and they fail in a predictable order. Watch for a controller that runs then quits after a few minutes, which is heat protection doing its job and usually means blocked vents or a motor drawing too much current. Watch for range that drops through the afternoon, which is normal lead-acid sag made obvious by an aging pack. Keep watering.

If the cart is at a house you are leaving for the summer, leave it on a maintaining charger or charge it fully and arrange for someone to check it monthly.

October and November: the honest test

This is the month to load-test the pack, individually, battery by battery. Resting pack voltage tells you almost nothing: a tired battery reads healthy sitting still and collapses the moment it is asked for current. Six numbers under load tell you whether one failing battery is dragging five healthy ones, which on a young pack can sometimes be fixed for the price of one battery, or whether the pack is uniformly finished, which cannot.

Do it now rather than in January, for a straightforward reason: cold reduces the current a lead-acid pack can deliver. The pack that is marginal in October is the pack that will not move the cart on the first cold morning. Finding that out in autumn is a planned purchase. Finding it out in January is an emergency.

Also now: brakes and tires, before anyone is relying on the cart in wet weather, and lights, if the cart is street legal and subject to inspection.

December through February: parked, or parked properly

Mild here does not mean warm, and cold snaps are real. If the cart is going to sit:

Charge it fully first. A fully charged battery resists freezing far better than a discharged one, which is the whole argument in one sentence.
Leave it on a maintainer, or have someone charge it monthly.
Water it before you park it, not when you come back.
Disconnect anything that draws current while parked. A small permanent draw over three months is a flat pack.
Do not put a cover on a damp cart. In salt air, a cover over moisture is a corrosion chamber.

The one-page version

When	Do this
March to April	Wash battery tops, coat terminals, clear charger and controller vents, tire pressure, book the annual service
May to September	Water the pack every two to four weeks, distilled, after charging
Before 1 June	Storm plan, healthy charged pack, photos for insurance
July to August	Watch for heat cutbacks and afternoon range loss
October to November	Load-test every battery, brakes, tires, lights
December to February	Full charge, maintainer, water before parking, no cover on a damp cart
After any storm	Terminals, charge port, roll test; never charge a cart that stood in salt water

The annual tune-up at $100 to $200 on an electric cart covers the watering, the individual load tests, the terminal clean and coat, brakes, tires, lights and connections in one visit. In this climate it is the difference between a pack that lasts three years and one that lasts five, and it is the cheapest item on the price list.
