As it appears, golf cart batteries do bubble when charging. As during the charging period, a bubbling or boiling sound is quite normal, regarding new batteries, as this is a vital process that battery packs must go through to harden the new lead within the batteries, a process known as curing the lead.
Why are my golf cart batteries boiling after curing?
It is important to note that if your golf cart batteries are still making a loud bubbling or boiling noise after the curing process, your batteries could be experiencing an overcharge situation. This is a dangerous phenomenon as batteries emit a gaseous fume during the charging process, and too much heat or a spark could cause an explosion.
How to charge golf cart batteries?
Charging your golf cart batteries is not as challenging as it sounds. The following tips can help you charge your batteries: Turn the ignition key of the golf cart to the OFF position.

Why Do Golf Cart Batteries Bubble When Charging?
As stated, golf cart batteries charging noise when bubbles are created for the chemical reaction happening due to the curing process. The bubbling motion will get lower once your cells have finished the “new” procedure they must go through, but your batteries always should create a bubbling sound while charging for the process to be completed.
Do Golf Cart Batteries Boil When Charging?
Just as the bubbling sound, golf cart batteries charging noise include bubbling noises as well. It’s true that during charging, your golf cart battery is exposed to a lot of electric fields, which puts pressure on the battery acid and the liquid inside the batteries.
Why Do Golf Cart Batteries Boil When Charging?

Do Golf Cart Batteries Smell When Charging?
Golf cart batteries emit all sorts of smell, from smoking, burning smell to sulfur and rotten eggs. After a given amount of time, golf carts begin to stink, and the odor becomes evident. Have you really pondered why this odor originates? The depletion from the golf cart’s batteries is responsible for the rotten egg-like odor.
Why Do Golf Cart Batteries Smell When Charging?
The smell is merely created due to the chemical reactions happening in the battery when it is being charged, quite similar to the process of golf cart batteries charging noise. Actually, they both can happen simultaneously.
Why is my golf cart charging red?
Occasionally a red fault light on a golf cart charger can mean that the batteries do not have enough voltage in them to allow the charger to kick on (see Charging Dead Golf Cart Batteries above).
What wires are needed to charge a golf cart?
Only the red and black wires are needed to completely charge the golf cart. The blue wire is an optional safety wire. If hooked up to the motor controller it will not allow you drive the golf cart while charging it. Think about being at the gas pump and driving off with the pump still in the car.
What is an OBC on a club car?
When you plug the charger into your Club Car, the OBC will tell the battery charger when to start and stop charging based on the voltage levels in your batteries.
What voltage do you need for a 36V golf cart?
You must match volts to volts. A 36V cart requires a 36 volt golf cart charger. A 48V cart requires a 48 volt golf cart charger. You can burn up your batteries if you do not charge with the proper voltage.
How many volts does a golf cart battery need?

Should golf cart batteries be charged after every use?
Yes. Charging your golf cart batteries after every use – even if you’ve only spent five minutes driving – is crucial for maximising their lifespan. Leaving batteries in a prolonged state of low charge can decrease their capacity over time and wear them out quicker.
Should you charge new golf cart batteries?
Yes. New golf cart batteries should be charged every time they are used as this will extend their lifespan, help them retain their capacity for longer, and prevent discharge. It is vitally important to charge new golf cart batteries, even after their first use.
Should your golf cart be turned on when charging?
No. You should turn your golf cart off when charging its batteries. Trying to charge a golf cart while it is running is a pointless exercise, as the battery will be draining while you’re trying to charge it. A golf cart should only be turned on once its batteries are fully charged.
Should golf carts be plugged in all the time?
No, you should not leave your golf cart plugged in all the time. While automatic battery chargers are designed to shut-off once at full capacity, leaving a battery connected to power for long periods leaves it susceptible to damage should the electrical circuit be overloaded.
Should golf cart batteries make noise when charging?
If your golf cart uses a standard 12 volt flooded lead acid battery, then it is quite normal to hear a bubbling sound when it’s charging. However, if your cart uses a sealed battery (such as a gel or AGM battery), then a hissing or bubbling sound may indicate damage.
How long should golf cart batteries last?
If you play golf twice a week – and use your golf cart for each round – you can expect a standard, brand-new battery to last just under 10 years before needing to be replaced. If you charge your battery correctly after use, you can maximise its shelf life.
How does a Lester golf cart battery charger work?
The Lester Electric Golf Cart Battery Charger you purchased is a transformer style charger that is designed to apply amperage and voltage for a length of time that replaces the energy used from last discharge. This is fairly old technology but very effective to charge your golf cart batteries. Depending on the battery chargers output (Amperage), the batteries size (Capacity), and DOD (depth of discharge), all this will determine the amount of time required to fully charge the battery bank in question. In the process as they reach maximum capacity the more electricity that is forced into the batteries the more it excites the electrolyte and gets electrons moving in the battery itself… (That is the boiling sound you hear)
Why are AGM batteries so picky?
AGM and Gel style batteries are even more picky than traditional lead acid batteries because they like more voltage and amperage to complete the same process. Hopefully this was helpful and insightful to ease your worries about your golf cart batteries and the golf cart battery charger.
Why do lead acid batteries make noise?
Make no mistake lead acid batteries will always make noise in the charge process and finishing phase because of the specific chemistry and design that make a lead acid battery. It is also an important part to insure good battery health as well.
