Lithium batteries have a calendar life of maybe 15 years usually because of electrolyte and lattice breakdown...They won't last 39 years, yet.
Driving 5000 miles a year on a cart with ~80 mile range (210ah Star Sirius/Atlas): After 15 years and 75,000 miles you will use about 1000 charge cycles. The degradation on a LFP battery might be 10% after 1000 cycles so you will only be getting 72 miles per charge.
75,000 miles / 15 years on a gas cart would be 60 oil changes at $60 dollars or $3600. Just that one expense pays for a replacement lithium battery. Lithium carts cost one cent per mile in fuel - gas cart 10 cents per mile in fuel - $750 electric - $7500 gas. $6,750 saved.
Are you starting to see the value?
No gas cart ruckus, smell, and laughably awful throttle response. No gas cart maintenance and refueling inconvenience/expense.
The replacement battery 15 years from now will probably be Sodium Ion and cost $1500 in todays dollars.
To fill your automobile with gas might cost $50...Your electric golf cart charging will cost $50 per YEAR
