Car and golf cart batteries may seem similar at first glance, but there are some important differences between them that every golf cart owner should be aware of. We’ll explore these differences here, highlighting the benefits and considerations of lithium golf cart batteries. If you’re wondering what’s the difference between car versus golf cart batteries, Big Battery is here to help!
Battery Chemistry
Car batteries are typically lead-acid batteries with the ability to produce high cold-cranking amps, being designed to provide a high current output for a short period of time – just enough to start the vehicle’s engine. Once the engine is running, the alternator takes over to power the vehicle and recharge the battery.
In contrast, golf cart batteries need to provide a steady flow of power over an extended period for propulsion and accessories. This is where lithium golf cart batteries shine, as they offer a more constant power output, longer battery life, and faster charging times compared to traditional lead-acid golf cart batteries.
Voltage Requirements
When looking for the differences between car and golf cart batteries, you’ll notice that voltage plays a role. The voltage requirement of a car battery is generally fixed at 12 volts. However, golf carts have varying voltage depending on the make and model, but all carts start at 36 volts and go up from there. Lead-acid golf cart batteries typically come in lower voltages, creating a need for multiple batteries to be connected in series to achieve the required voltage or capacity.
Lithium golf cart batteries often come with higher voltage options, allowing for fewer batteries to be used. This results in a lighter and more efficient power system for your golf cart.
Capacity and Discharge Rates
The primary job of a car battery is to start the engine, while the golf cart battery is responsible for powering the cart throughout the entire journey. As a result, golf cart batteries need to have a higher capacity to ensure that you can enjoy a full day of golf without worrying about your cart running out of power.
Lithium golf cart batteries provide a higher energy density compared to lead-acid batteries, meaning they hold more energy in a smaller and lighter package. Additionally, they have a steadier discharge curve, also known as continuous output, which means you’re less likely to experience a significant drop in power output as the battery drains.
Maintenance and Longevity
Car batteries typically require regular maintenance, such as checking electrolyte levels in older models, and cleaning terminals. On the other hand, lithium golf cart batteries are virtually maintenance-free, as they do not suffer from issues like sulfation or stratification. This makes them a more convenient option for golf cart owners.
Lithium golf cart batteries also boast a longer life span, lasting up to 3 – 5 times longer than their lead-acid counterparts. This translates into significant long-term savings, as you won’t need to replace your golf cart battery as frequently.

Frequently Asked Questions
How long do LiFePO4 batteries last?
A quality LiFePO4 battery can commonly deliver 4,000 or more charge cycles, often roughly 10 years or longer under the right conditions. Depth of discharge, temperature, charge settings, storage habits, and the BMS all affect the result.
How many years is 4,000 cycles?
One full cycle per day is about 11 years. Three cycles per week is more than 25 years on paper, though calendar aging becomes the limit first.
What happens at the end of a LiFePO4 battery's life?
It does not suddenly stop. It loses capacity gradually. A battery rated for 4,000 cycles may be specified to keep around 80% of its original capacity at that point.
Does temperature affect LiFePO4 battery life?
Yes. High heat speeds aging, and charging below freezing can damage cells unless the battery has low-temperature protection or self-heating.
How long does a lithium battery last in an RV?
Many years, when charging sources are configured correctly and the battery is protected from freezing charge conditions. Annual cycles are often fewer than in a daily solar system, but conditions vary more.
How should I store a lithium battery?
Store it at a partial state of charge in a clean, dry, moderate-temperature location. Disconnect parasitic loads and check it periodically per the manufacturer's guidance.
