Select Your Battery

Choose your battery type and enter its age. Lithium batteries offer 2-3x the range of lead-acid and degrade much slower over time.

⛰️

Add Your Conditions

Select the terrain you'll be driving on and enter the total rider weight. Hills and heavy loads reduce range significantly.

Frequently Asked Questions

How far can a golf cart go on a full charge?

It depends on the battery. Lead-acid 36V systems typically get 12-18 miles, 48V lead-acid gets 18-25 miles, 48V lithium gets 25-35 miles, and 72V lithium can reach 40-50 miles. These ranges decrease with hills, heavy loads, and battery age.

How long do golf cart batteries last?

Lead-acid batteries typically last 4-6 years with proper maintenance (regular watering, equalization charges, and avoiding deep discharges). Lithium batteries last 8-12 years and require no maintenance. Lithium costs more upfront but the longer lifespan often makes it cheaper per year.

Should I upgrade from lead-acid to lithium?

Lithium batteries cost 2-3x more upfront but offer 2-3x the range, charge 3x faster, weigh 60% less, last 2-3x longer, and need zero maintenance. For rental fleets, the faster charge time and longer lifespan usually justify the investment. The lighter weight also reduces wear on tires and suspension.
