How to Check Golf Cart Battery Voltage

Checking your golf cart's battery voltage is the fastest way to assess battery health without special equipment. All you need is a basic digital multimeter available at any hardware store for $15–$30. This guide walks you through the process safely and accurately.

For reference values to compare your readings against, see our golf cart voltage chart.

What You'll Need

Digital multimeter (any brand — you need DC voltage measurement)
Safety glasses (batteries can emit hydrogen gas; standard precaution)
Nitrile or rubber gloves (recommended when working around batteries)

Step 1: Set Up Your Multimeter

Turn the dial to DC Voltage (labeled V with a straight line, or V⎓)

Select a range higher than your expected voltage. For a 48V pack, use the 200V DC range if your meter doesn't auto-range

Most modern digital multimeters auto-range — if yours does, just select "DC V" and it handles the rest

Do not use AC voltage (labeled V~). Golf cart batteries are DC only.

Step 2: Access the Battery Compartment

Lift the seat or open the hood to access the battery tray
Identify the full battery pack: you should see multiple batteries connected by cables
Identify the main positive terminal (usually red cable, + symbol) and main negative terminal (usually black cable, − symbol) of the entire pack

On most carts:

The positive terminal of the pack is the positive terminal of the first battery in series
The negative terminal of the pack is the negative terminal of the last battery in series

Step 3: Measure the Full Pack Voltage

Touch the red probe (positive) to the pack's positive terminal

Touch the black probe (negative) to the pack's negative terminal

Read the display

Your Reading	What It Means
36V system: 38–39V	Fully charged and healthy
36V system: 34–37V	Partially charged or mildly discharged
36V system: Below 33V	Discharged or failing batteries
48V system: 50–52V	Fully charged and healthy
48V system: 46–50V	Partially discharged
48V system: Below 45V	Deeply discharged or failing
72V system: 76–78V	Fully charged and healthy
72V system: 69–75V	Partially charged
72V system: Below 68V	Deeply discharged or failing

Step 4: Test Individual Batteries

Testing each battery individually identifies which one (if any) is failing. A pack with one weak battery will underperform even if all others are healthy.

Set your multimeter to DC voltage

Touch the red probe to the positive terminal of the first battery

Touch the black probe to the negative terminal of the same battery

Record the reading

Repeat for each battery in sequence

Battery Type	Fully Charged	Discharged	Failing
6V battery	6.37V	5.8–6.0V	Below 5.5V
8V battery	8.5V	7.75–8.0V	Below 7.5V
12V battery	12.75V	11.6–12.0V	Below 11.0V

If one battery reads significantly lower than the others, it's likely the weak link dragging down the whole pack.

When to Take Readings

Best time: 1–2 hours after charging (resting voltage — most accurate)
After driving: Voltage will be lower than resting state due to discharge
Immediately after charging: Voltage may read slightly higher than actual due to surface charge

What If Readings Are Low?

If your pack reads in the "deeply discharged" range:

Attempt a full charge cycle

Wait 2 hours after charging completes

Re-test resting voltage

If it's still low, one or more batteries may have a failed cell

A professional load test (testing voltage under actual current draw) is more definitive than a static voltage test. TIGON Golf Carts offers free battery load tests at all 16 physical stores. Call 1-844-844-6638 to schedule yours.
