However, one of the most important aspects of owning a golf cart is ensuring the batteries are adequately charged. This article on How to Charge 48 Volt Golf Cart Batteries with 12 Volt Charger provides adequate instructions for charging a 48 volt golf cart battery with a 12 volt charger.
If you don’t have a 48 volt charger or want to know how to charge your batteries on the go, this article is for you.
How to Charge 48 Volt Golf Cart Batteries with 12 Volt Charger (Step-by-Step Guide)
Using a 12 volt maximum output charger to charge a 48 volt battery will take a long time to charge the battery fully. Using the wrong type of charger can damage the battery, so it is also essential to use a charger specifically designed for lead-acid batteries.
The following steps should be taken to charge 48 Volt golf cart batteries with a 12 Volt charger:
- Ensure the golf cart is powered off and the charger is unplugged.
- Your 48 volt battery for your golf cart should be under the seat or in the front of the cart. Find it.
- Connect the charger to the battery pack, ensuring the charger’s positive (+) cable is connected to the battery’s positive terminal and the negative (-) cable is connected to the negative terminal.
- Set the charger to 12 volts and plug it in.
- Charge the battery for at least 8 hours or until the indicator light on the charger indicates the battery is fully charged.
- Once the battery is fully charged, disconnect the charger from the main power and the battery pack.
- Turn on your golf cart and test the battery to ensure it is getting enough power.

Can You Charge a 48v Battery with a 12v Charger?
Yes, you can charge a 48 volt golf cart battery with a 12 volt charger by connecting multiple 12 volt chargers in a series to increase the voltage and charge the 48 volt batteries.
Can I Charge My 48 Volt Golf Cart Battery with A Regular Battery Charger
Yes, you can, but it is essential to check the specifications of the charger and battery to determine if they are compatible. This is because most regular battery chargers cannot charge 48V golf cart batteries and may not have enough power to charge the battery properly.
It is also important to note that the charger may not have the correct voltage and current settings for the 48V battery. We also recommend using a charger specifically designed for golf cart batteries.
Potential Challenges in Charging 48 Volt Golf Cart Batteries with 12 Volt Charger and Solutions
Not all 48 Volt golf cart batteries are the same, and charging it with a 12 Volt charger may pose some challenges. Here, we will present those possible challenges and solutions to them.
- A potential challenge is that the amperage of a 12 volt charger is insufficient to charge a 48 volt battery. This can cause the battery to overcharge or undercharge. The solution to this problem is to use a higher amperage charger or multiple 12 volt chargers in parallel to increase the total amperage.
- Another potential challenge with charging a 48 volt golf cart battery with a 12 volt charger is that the voltage difference between the battery and the charger is too significant. As a result, the charger may not be able to charge the battery correctly. The solution to this problem is to use a voltage converter or step-up transformer to boost the charger voltage to match the battery voltage.
- A 12 volt charger may not be compatible with a 48 volt battery, resulting in improper charging or not charging. The solution to this challenge is to check the charger and battery compatibility before use or use chargers explicitly designed for 48 volt batteries.
What is the proper charging voltage for 48 volt golf cart batteries?
The proper charging voltage for 48-volt golf cart batteries is around 54 volts.
Is it okay to use a 12 volt charger on a 48 volt golf cart battery system temporarily?
Yes it is okay to use a 12-volt charger on a 48-volt golf cart battery system temporarily, but not recommended.
Can I charge 48 volt golf cart batteries overnight?
Yes, you can charge 48-volt golf cart batteries overnight. However, it is important to use a charger with an automatic shut-off feature to prevent overcharging and damage to the batteries.
Conclusion
I hope you now know the answer for “How to Charge 48 Volt Golf Cart Batteries with 12 Volt Charger”. You can connect multiple 12 volt chargers in series to step up the voltage to charge a 48 volt battery. Using the correct amperage charger and monitoring the charging process is essential to ensure the battery is not overcharged or damaged.
