Can You Use Regular Car Batteries in a Golf Cart? The short answer is yes. Standard car batteries are 12-volts, and you could connect three or four of them in series to provide the required 36 or 48 volts to your golf cart motor. However, the design of car batteries provides a huge surge of current for short periods.
Can I put 4 12-volt batteries in my 48 volt golf cart?
For example, a typical 48-volt golf car may use eight 6-volt batteries, six 8-volt batteries, or four 12-volt batteries.
Can you use 12-volt batteries instead of 6-volt batteries in a golf cart?
If you have a 36-volt golf cart that runs on six 6-volt batteries, you can replace them with three 12-volt batteries, which often are easier to find.
Can I use 12v battery instead of 6v battery?
Yes, you can use a 12-volt battery on a 6-volt battery. However, you will need to make some adjustments to the wiring system and perhaps the converter to get the best results. Note that if a Power Wheels car uses a 6-volt battery, chances are most of the electronic components are rated 6 volts.
Can you use 12 volt marine batteries in a golf cart?
The Technical Answer: Yes
It's possible to use a marine battery in place of electric golf cart batteries. They're both technically gel lead acid batteries designed for deep-cycle purposes, reports It Still Runs. However, this similarity doesn't mean that they should be used interchangeably.

- Smear petroleum jelly over the battery terminals and clamps to inhibit corrosion.
What type of battery does a golf cart use?
The majority of golf carts driven today use a 6-volt golf cart battery, which is why most online searches for golf cart batteries tend to take you straight to 6v options.
What happens if you charge a 6 volt battery with 12 volts?
At proper charging voltage, the internal heat is never high enough to damage the battery, but at 12V, the internal heat can actually cause the electrolyte inside the battery to boil. This will run your battery dry and create a thermal runaway scenario, which is very dangerous.
Can you upgrade a 6v battery to a 12v?
You can use a 12v battery in 6v Power Wheels. To convert a 6v to a 12v, cut the plug off the stock 6v battery, then attach the white (+) wire to an inline fuse holder with a 30amp fuse. Next, connect the black (-) wire to a separate wire. Lastly, fit both ends with a 12v battery quick connect.
Can you use a 12v battery on a 6 volt starter?
A 6-volt starter will work just fine with 12-volts.
Can you mix batteries in a golf cart?
Generally, mixing old and new batteries is not recommended due to possible issues with performance and safety. No matter what type of battery you use and the brand manufacturer, all batteries will eventually lose their electrical capacity as they age.
Can you charge a 48v golf cart with a 12V charger?
These batteries are designed to be discharged almost completely and repeatedly with low loss in performance. Golf carts usually come with their own charger, however a car charger can also be used to charge a golf cart. The trick is matching the voltage of the charger to the voltage of the batteries.
Can I use regular deep-cycle batteries in my golf cart?
These batteries supply enough power for the golf cart to be used for an entire 18-hole round of golf. Golf carts can be modified to use 12-volt marine deep-cycle batteries, but this modification would not provide nearly the battery life as golf cart batteries.
How many batteries does a 48v golf cart have?
Lithium 48 Volts Golf Cart Battery Packs
Long Story Short: If your golf cart has a 48-volt electric system and you have lead-acid batteries, then you have 8 (eight) 6-volt batteries, or 6 (six) 8-volt batteries, or 4 (four) 12-volt batteries.
Can I convert 6V to 12V?
When you convert to 12V you can still use your existing 6V distributor; the only component that has to be changed is the condenser (it must be upgraded to a 12V type). The ignition coil must also be changed to a 12V coil.
What is the difference between a 12 volt and 6 volt battery?
A battery is full of cells with chemicals that transfer ions back and forth to create electricity. Each cell in a deep-cycle battery can produce about 2 volts. A 6V battery has 3 cells, making a total of 6 volts, and a 12V battery has 6 cells, making a total of 12 volts!
What is the difference between a 6-volt and 12 volt power wheel?
12v cars use 12-volt motor and battery, 6-volt cars use 6-volt motor and battery. As a result, 12-volt ride on cars have more power, more speed and need more charging time than 6-volt cars. 12-volt vehicles are suitable for 3 to 6 years old kid whereas 6-volt cars are generally for 1 to 3 years old.
Can you charge a 12V battery with a 24v charger?
Yes, if you regulate the voltage down to the right amount. If you just plug a 12 volt a battery into a 24 volt charger it will die in a matter of hours.
Can I use a 12V solar panel to charge a 6V battery?
The second lesson is that while you can use a larger rated voltage device to charge a smaller voltage rated batter, the process can be dangerous. For example, using a twelve-volt solar panel to charge a six-volt battery can lead to permanently damaging the battery, exploding, or causing a fire.
Can I charge a 5V battery with a 12V charger?
Yes, it is absolutely safe to charge a device with a charger that has more current capacity than needed. Since the voltage is held constant (5V), the only factor that determines current draw is the load (another term for resistance) the device places on the charger.
What volt are golf cart batteries?
The standard electric golf cart will have four, six, or eight batteries in total. The voltage will be either 36 volts or 48 volts. These batteries will be contained in a single system, that looks a bit like a large block/box.
Why do golf carts use 8 volt batteries?
8-volt batteries have a higher depth of discharge percentage than 6-volt units, which means they will require more charges during their lifespan. Resulting in a shorter lifespan than a 6-volt unit.
What size batteries do golf carts use?
Golf Cart Battery Types
Wet/flooded lead-acid batteries are mostly GC2/GC2H (6V), GC8/GC8H (8V), and GC12 (12V) group batteries.
Are golf carts 12 volt?
Golf cart batteries are lead acid batteries available in 6, 8 or 12 volts. The average golf cart requires four to six batteries in order to operate (occasionally you'll encounter a golf cart that requires eight). When purchasing a replacement, be sure to check the operating voltage of your specific golf cart model.
How do you get a 12v from a 36v golf cart?
Another way to put a 12 volt accessory on your 36 volt system will require you to purchase a voltage reducer. This will take the combined voltage or your entire battery pack and reduce it to 12 volts. Installing a voltage reducer will increase the longevity of your entire battery pack.
