How Long Does a 100Ah Battery Last in a Golf Cart?

May 30, 2025

A golf cart's battery is its power source, determining how far, how fast, and how reliably you can drive. Among the most popular options is the 100Ah (amp-hour) battery, but understanding how long it will last in your golf cart depends on a variety of important factors.

In this article, we’ll break down what a 100Ah rating means, the real-world range expectations, and the key factors that influence battery performance.

What Does 100Ah Mean in A Battery?

The term 100Ah (ampere-hours) refers to a battery's storage capacity—how much energy it can deliver over time. A 100Ah battery can theoretically supply 100 amps for one hour, or 10 amps for 10 hours, depending on your golf cart’s power consumption.

Key Factors That Affect Golf Cart Battery Runtime

While energy is primary factors in determining how long a battery last in a golf cart, the golf cart batteries runtime can vary depending on these conditions:

Battery Type (Lead-Acid vs. Lithium)

Lithium batteries typically outperform lead-acid batteries of the same capacity, because they provide a steady voltage and power output during discharging, whereas lead-acid batteries voltage drops significantly during using.

Driving Conditions

Smooth and flat terrain consumes less energy, while hilly, rough, or sandy surfaces increase power usage and reduce range.

Speed and Driving Habits

Frequent acceleration and high speeds can quickly drain the battery.

Load Weight

More passengers, equipment, or cargo increase the strain on the battery, reducing overall runtime.

Battery Age and Health

Older or poorly maintained batteries may not hold a full charge, resulting in shorter runtime compared to new or well-maintained ones.

Weather and Temperature

Cold temperatures can decrease battery efficiency, while extreme heat may impact battery lifespan over time.

Tire Pressure and Cart Maintenance

Low tire pressure or mechanical issues in the golf cart can force the motor to work harder, consuming more energy. If this occurs, servicing the cart promptly to maintain safe and reliable performance.

Calculating 100Ah Battery Runtime in a Golf Cart

Most electric golf carts at 15 mph typically consume between 40 and 80 amps during regular use. Based on this, we can estimate how long a 100Ah battery will last:

  • At a 40-amp draw: A 100Ah battery can provide power for approximately 2.5 hours (100Ah ÷ 40 amps = 2.5 hours).
  • At a 60-amp draw: When in 60 amps of current, a 100Ah battery can power the golf cart for approximately 1.67 hours (100Ah ÷ 60 amps ≈ 1.67 hours)
  • At a 80-amp draw: With a higher current draw, the battery’s runtime decreases to about 1.25 hours (100Ah ÷ 80 amps ≈ 1.25 hours).

For average driving conditions on moderate terrain with a typical load, you can expect a 100Ah battery to run your golf cart continuously for about 1.25 to 2.5 hours. 

What is the Range of a 100Ah battery in a Golf Cart?

The range of a 100Ah battery in a golf cart depends largely on the system voltage and motor power. Common golf cart systems are 36V, 48V, and 72V. 48V or 72V systems deliver more power than 36V system stably and efficiently, improving overall runtime and performance.

Voltage System Estimated Range (Miles)
36V Battery 30–40 miles
48V Battery 40–50 miles
72V Battery 60–75 miles

Take our Redodo 48V 100Ah Lithium Golf Cart Battery as example, it generally delivers around 40 to 50 miles per charge, offering a good balance of power and runtime for most golf carts.
