The discussion about how to choose golf car batteries from various types has been ongoing for a long time now. Normally,to choose between lead based batteries and lithium batteries is an endeavor well directed.The process just like finding the best gas to power your car.You need to choose the right one, because this a lot depends on your decision.

Technological differences lead to differences between lead-based and lithium-ion batteries.Lithium-ion batteries are clearly an improvement over lead-based batteries.In this article we will discuss about lead based batteries and lithium batteries for your golf cart. From analyse these two types of batteries, golf cart owners maybe wanting to change batteries or a new buyer.


Lead-Acid Batteries

Lead-acid batteries are the oldest rechargeable battery in existence ,which was invented in 1859 by a French physician Gaston Planté and still existing in the market.The system consists of lead plates immersed in sulfuric acid solution, to provide a reliable instant power supply to equipment and devices.The low cost and excellent high-surge currents bring them a huge market.

Benefits of lead-based batteries

  • Stable performance: With years of efforts, most shortcomings of it have been overcome.The advantages of lead-acid batteries lie in power and performance.
  • Non-flammable: Lead-acid batteries are not flammable, very safe to use, they are designed under standard pressure, very safe to use, no explosion risk.
  • High voltage: Lead-acid batteries ensure stable high-voltage power supply, which are suitable for hybrid vehicles and applications requiring high discharge rates.
  • Suit variety needs: Unique for peak load and valley clipping,Excellent for applications requiring peak performance of shallow charge and discharge, etc.
  • Easy maintenance: Because of the simple composition and availability of parts, lead-acid batteries are easy to maintain.

Lithium batteries

Lithium-ion battery is excellent for renewable energy uses.Sonny first produced it commercially in 1991.Compared with previous technologies, this technology is extremely stable and high performance. Lithium ions have six different chemical reactions, each with its own unique properties.

Benefits of lithium batteries

  • No maintenance: Unlike lead-acid batteries,they are maintenance-free.
  • Lighter wight: Lithium-ion batteries are lightweight, can makes your cart lighter, it is also the ideal option for a luxury electric golf cart.
  • Adequate power: An adequate supply of electricity. Because of its powerful power output,you don’t need to worry about your cart can not climbing hills.
  • Load characteristics: The load characteristics of a lithium ion battery are quite good. As the last charge is used,they still provide a constant 3.6 volts per cell before falling off.
  • No requirement for priming: When some battery receive their first charge,they need to be primed. One advantage of lithium-ion batteries is that it is no requirement for this.

Comparison of lead-acid batteries and lithium battery

Lithium-ion batteries are half the size and weight of lead-acid batteries, so golf carts with lithium-ion batteries have a significant power-to-weight ratio enhancement. This means that the golf cart can reach higher speeds with less effort, and can carry more weight without the power fading and the performance diminishing.


One of the main advantages of lithium-ion batteries is that they do not require any maintenance, whereas lead-acid batteries require regular checks and maintenance. So,man hours and the extra costs of maintenance tools and products are saved.No lead acid means owntime on your golf cart is greatly reduced and chemical leaks are avoided.

Charging time
Normally, to fully recharge a lead-acid battery need eight hours. However, with one-hour chrage, a li-ion battery can be recharged up to 80 percent, and 100 percent no more than four hours. In addition, partially charged lead-acid batteries are vulnerable to sulfuric acid damage, which means if the golf cart is charged below 100 percent, the battery life is significantly reduced.Lithium-ion batteries, by contrast, don’t have any negative effects. This meaning users can “recharge” their vehicles by plugging them into a charger for a quick charge, which can quickly restore a lot of power to the battery system, rather than the lengthy charging cycle required for lead-acid batteries.

Cycle span

Compared to 500 and 1000 for lead based batteries, lithium batteries have a higher life cycle between 2000 and 5000 times.


There is no hazardous material captained in li-ion batteries. But, lead-acid batteries, just like the name,contain lead which is harmful to the environment. However,they are both recyclable.
