What you need to know about golf carts battery?


1.What are golf cart batteries?

Golf cart batteries are different from car starter batteries. They are deep cycle batteries that can be deeply discharged while powering an electric golf cart battery for miles.General golf cart batteries have 6V, 8V, 12V, etc., depending on your application scenario.

2.Common Golf Cart Batteries

1.Submerged lead-acid (wet) battery

Submerged batteries, also known as wet batteries, are the most common cycle solar cells. For submerged lead-acid batteries, it is necessary to add water frequently, to balance it regularly, and sometimes it is necessary to use a hydrometer to measure the specific gravity of the electrolyte. Under certain battery charging conditions, they may release hydrogen gas, causing the battery to require ventilation to release fumes.

2. AGM lead-acid battery

AGM batteries are an alternative to traditional submerged lead-acid batteries, which feature maintenance-free and provide a strong starting current.

3. Colloidal lead-acid battery

Colloidal is a type of lead-acid battery. It is modified from a normal lead acid battery, so there are many similarities. Among them, the sulfuric acid electrolyte is replaced by a colloidal electrolyte, thereby improving safety, energy storage, discharge performance and lifespan.

4. Lithium-ion golf cart battery

Lithium-ion golf cart batteries are not a mainstream product on the market because the upfront cost of lithium-ion batteries is higher than that of lead-acid batteries. The lead-acid battery has the characteristics of large capacity, so it is very popular among people. However, with the improvement of people's safety awareness, more and more people use lithium-ion batteries on the market.

3.The Best Batteries for Golf Carts: Lithium-Ion Batteries

Compared to other types of batteries, lithium-ion batteries remain stable over hundreds of charges. Under the same conditions, Li-ion has higher energy density, voltage capacity and lower self-discharge rate.

4.Compared with lead-acid batteries, what are the advantages of lithium-ion batteries?

1.Longer lifespan and warranty period

Compared with lead-acid batteries, lithium-ion has a longer lifespan, and its lifespan is about 5 times that of lead-acid batteries. Lead-acid batteries are only covered for a few months, while lithium-ion batteries are covered for more than 5 years.

2.No need to cut off when the voltage drops

A BMS protection board is installed in the Li-ion battery to protect it when the voltage drops. A protective plate is attached to each unit. If one of the batteries is abnormal, the corresponding area of the protection board will be automatically disconnected, which will not affect the normal use of other batteries.

3.Fast charging speed

Lithium-ion batteries can output current to the maximum during the charging process, while lead-acid batteries only output half the current of lithium-ion batteries in order to maintain their service life.

4.Light weight

Lithium-ion batteries are about half the weight of lead-acid batteries. Therefore, in the case of the same capacity, the weight of lithium-ion batteries is relatively light.

5.Lower total cost

The reason why the total cost of lithium-ion batteries is not as high as that of lead-acid batteries is that lithium-ion batteries have a relatively long cycle life and do not need to be replaced frequently. In terms of safety performance, lithium-ion batteries are also superior to lead-acid batteries. So although lithium-ion batteries are more expensive in the early stage, they are indeed cheaper than lead-acid batteries in the long run.


The activity of lithium ion is higher than that of lead acid, so the environmental requirements are particularly high. The general lithium battery pack battery is 18650, which is equipped with an air valve to release when the air pressure is too high. There is no standard to measure the lead-acid battery, and there are many hidden dangers.

5.There are a few things to keep in mind when buying batteries.


Appropriate voltage, can play the best effect. It cannot be said that the higher the voltage, the better the effect. This has to be combined with practical applications.

2.Capacity matters

Proper battery capacity is important for golf carts, too low a capacity will result in the golf cart not going very far. Generally, the larger the capacity, the larger the volume of the battery. This needs to be combined with the actual space of a golf cart.

3.Choose the right brand

In the market, there are many unscrupulous businesses that recycle some old batteries, refurbish them, pretend to be good quality batteries, and then sell them for profit. They do not take into account the safety of consumers. And those big brand merchants generally do not have this situation.

4.Need to see terminals and wires

As a transfer interface, the terminal has a different experience for users. There are a variety of terminals on the market, and they can be customized.The quality of the wire is related to the safety of the user. Poor quality wires are prone to dangers such as short circuits. A good quality wire can prolong the life of the battery and protect the safety of the user.


There are various types of golf cart batteries, whether they are lead-acid or lithium-ion batteries. However, compared with lead-acid batteries, the advantages of lithium-ion batteries are more obvious. It has the characteristics of long service life, high energy density, and more safety. In addition, there are some things to pay attention to when buying batteries, such as voltage, capacity or terminals. Only by choosing the right battery can you get the most out of your desired application.
