How Long Do Golf Cart Batteries Last?

Driving on the green on a lovely day is a highlight for many. But what happens when your cart begins losing power and stops working in the middle of the course? Replacing your battery is one thing, but knowing when to replace it and how long your golf cart battery lasts can help.

Battery longevity is important for a successful and stress-free round of golf, or for any other reasons you would use a golf cart. There are two major types of batteries used for golf carts: lead-acid batteries and lithium batteries, and there are several differences between them that affect their lifespan.

Average Lifespan of Golf Cart Batteries

The average lifespan of a golf cart battery depends on the type of battery and how you’re using the cart. Most batteries, no matter what type, will have an average lifespan advertised with proper maintenance; however, if your golf cart is used heavily, that lifespan can shorten, especially if little to no maintenance is practiced.  The two most common batteries for golf carts are lead-acid batteries and lithium-ion batteries.

Lead-Acid Batteries

• Generally, it lasts 2-5 years with proper care.
• Performance decreases significantly when deeply discharged or poorly maintained.

Lithium-Ion Batteries

• Tends to last 8-10 years with up to 5,000 cycles due to higher efficiency.
• Requires less maintenance and provides more battery life.

 Key Factors Influencing Battery Lifespan

Aside from the differences between the types of batteries on a golf cart, other factors influence a battery’s lifespan, including the use and charging patterns, maintenance practices (either proper or improper), and outside environmental factors. 

Usage and Charging Patterns

A deep discharge is the complete emptying of the battery’s reserved power, making it go to 0%. Lithium batteries can properly function with deep discharges. Many LiFePO4 (lithium-iron) batteries are designed with deep discharges in mind. Lead-acid batteries, however, aren’t as forgiving. Constant deep discharge and frequent full charges will shorten the battery life.

Maintenance Practices

Lead-acid and lithium batteries each require certain maintenance practices to ensure proper battery life. If these practices are not followed, it can drastically reduce battery use and cause premature battery death.

Lead-Acid Batteries

• Fill up the tank with water to maintain chemical levels
• Properly charge batteries routinely
• Avoid over-discharging
• Avoid over-charging

Lithium-ion Batteries 

• Don’t leave it unused for long periods of time
• Make sure to store it in a cool, dry place when not in use

Environmental Factors

Outside environmental factors can also impact battery life. For example, high temperatures can cause battery degradation, and in the case of lead-acid batteries, require more water refills in the tank. Extreme cold conditions can also reduce the lifespan of the battery. Proper storage is necessary for any type of battery, away from the elements, to prevent a reduced lifespan.

5 Signs Your Golf Cart Battery Needs Replacement

No matter what kind of battery you have, you will eventually need to replace it. Here are five signs to look out for when you need to replace your battery.

• Sluggish Performance: The golf cart feels slower, particularly during uphill climbs.
• Reduced Charge Capacity: Noticeable decrease in the time or distance covered on a full charge.
• Longer Charging Times: The battery takes longer to charge but discharges quickly.
• Physical Symptoms: Visible swelling, corrosion, or leaking on lead-acid batteries.
• Low Voltage Readings: Battery voltage is consistently below normal levels despite charging.

Extending Your Golf Cart Battery’s Life

If you’re worried about your battery use and want to get the most out of your golf cart’s battery life, there are a few steps you can take. Different batteries will have different methods of extending their lifespan such as:

Lead-Acid Battery Tips

• Maintain proper electrolyte levels
• Avoid deep discharges
• Perform regular equalization charges

Lithium-Ion Battery Tips

• Use the correct charger
• Avoid extreme temperatures
• Let the BMS handle the charge

General Battery Storage Tips

• Routinely inspect the battery to make sure there’s no damage
• Store in a cool, dry place when not in use 

If you notice your golf cart battery isn’t charging as much, is sluggish, or appears damaged. It may be time for a new battery. Sunrich Energy has golfcart batteries that are ready to go, with enhanced BMS and top of the line LiFePO4 technology, it’s an investment you can count on.
