Imagine you are driving along the course on a sunny Spring morning, ready to hit your 2nd shot after a beautiful drive that split that fairway, and boom! Your golf cart dies. Now what?. One way to ensure that this never happens to you is to always make sure your battery is solid, and it will never die on you when you are out on the course.
Purchasing a battery meter is one of the best ways you can ensure that your battery has enough juice to get through the round or get to where you want to go.
Choosing the right one for you is important, there are several factors that come into play like the make/model of your golf cart, how it connects to your cart, and the best way to reset it. By following this buying guide and the in-depth reviews, we are confident that you will find what you need inside this article!
How Does a Golf Cart Battery Meter Work?
Golf cart meters are ingenious devices that will tell you the amount of battery remaining on your golf cart, jet ski, or any other device that has a 48V battery. They work by connecting the meter directly to the battery and reads the level of charge remaining in the battery, and then displays that to you by way of a digital output or an LED strip.
It is important to have this information for not only your short-term needs and to avoid being stranded out on the golf course with no battery, but also for your long-term battery life, too. By having the ability to easily see where your battery charge is upon powering up, you will be able to avoid allowing the battery to dip below 30%, which if done consistently, can lower the longevity of the battery.
You will also be able to notice when the battery’s full charge level starts to dip. After powering up on a full battery, your meter will tell you if your battery is getting an actual full charge, if it is not, this is an early sign of a battery going bad.
How do I Read a Golf Cart Battery Meter?
When it comes to choosing the best golf cart battery meter, the display should be at the top of your list of things that matter. There is a range of display options, some more detailed than others and some showing just the bare minimum. Each model will have some slight differences, but for most of the meters on our list, it is an LED driven solution.
The most common battery meter display combines the use of 10 different LED lights, spread across the meter in a horizontal line. On one end of the line will be a symbol or icon that represents that the battery is full and as it progresses from right to left, it will represent that the battery level is getting lower.
Some models will come with an LED strip that will have all 10 LED lights lit up when at full charge, while others will have a single LED lit up, and depending on which position it is in will represent the battery life.
There are several bonus features that you can find that help you more aware of your battery life that we find valuable. Many will feature a light changing LED process that occurs when the battery is less than 30%. Most often, the typical LED lights will be green and when the batter lowers to less than 30%, it will change to orange and then continue to red when it gets too low.
These features are great for people who may not be aware of their lower battery life.

How do I Install a Golf Cart Battery Meter?
Each battery meter will have a different installation process, largely dependent on the features that your golf cart battery meter will have but overall, most units will come with some similarities.
When you are trying to add a battery meter to your golf cart, the first thing you must do is decide where you want to install it on your dashboard. It should be out of the way of any steering columns or other equipment, but still very easily seen by the driver.
Once you have decided the perfect place for it, you will need to Dremel or cut a hole for the meter to be housed in. Be very careful though, often, a 2.5” display will only require a 2” hole. The instructions will identify the hole size you need, read them! The next step will be prepping your wires.
You will need anywhere from 8-12” of wire, and we suggest a gauge between 14-18. That is more than enough. You will need to prep both ends with trimmers or wire strippers, to expose the wire for connectors.
Now you can connect one end of the wire to the butt connectors and provided connectors that come with your battery meter. This should be an easy process and they should be able to click-in very easily. Now, the next step is where we may find some variance. Most golf carts will come with additional wiring behind the ignition switch that is designed for this exact reason.
If this is the case, those can be directly installed on your meter. If you do not have these wires, follow the instructions and it will explain to you how to attach both the positive and negative wires directly to the battery.
How do I Reset a Golf Cart Battery Meter?
There are several ways to reset the meter, and we suggest doing this every time you connect your meter to a new battery. Many battery meters will have a reset button on the back or somewhere obvious, while others will actually reset themselves every time they power down. This is not the best route for those of you using batteries intermittently, but it is a nice feature if you are bouncing around to other vehicles.
When you first install a battery meter, you will see that many will have a 5 to 6-minute startup time where they are diagnosing the battery and finding the exact charge. We like this feature because we have found that units with this feature seem to be far more accurate in their readings than the alternative options.
Golf cart battery meters are one of the best ways you can keep tabs on your battery throughout your golf round. Not only do they give you up to date information on the status of your battery, but they also do a wonderful job of identifying future battery issues and saving you from headaches down the road.
If you are fortunate enough to have a golf cart of your own, the best thing you can do is find a quality battery meter to make the cart an even better asset. Installation is simple for most people and the benefits are endless.
