Frequently Asked Questions about Golf Cart Chargers

How long does it take to charge my golf cart?

This can vary depending on your current state of charge, the quality of your batteries & charger, and other factors. A smaller 2-5 amp charger could take over 10 hours. You can take a pretty good guess using this formula:

(Battery Capacity) / (Charger Amps) = Hours

For example, if you have a 180 amp-hour battery system and you are using a 20 amp battery charger, it would take approximately 9 hours to go from fully discharged to about 80% of the battery system's capacity. Then, likely an equal amount of time to recharge that last 20% of capacity. Some chargers might get there a little faster, but there is no guarantee.

Can you leave a golf cart battery charger plugged in?

It depends on the type of charger you’re using, as some golf cart battery chargers are designed to turn on and off automatically. Most automatic golf cart chargers can stay plugged in without overcharging; these modern carts enter a maintenance or float mode to keep batteries fully charged without overcharging. However, many older carts came with manual-style chargers that need to be disconnected when charging is complete. These chargers should be unplugged once the batteries are full to prevent damage. Additionally, in general, lithium chargers should not be left plugged in indefinitely unless the charger manual specifies otherwise.

Why is proper maintenance for golf cart battery chargers necessary?

Proper maintenance keeps golf cart battery chargers working safely and helps your batteries charge the way they’re supposed to. A well-maintained charger delivers steady power, meaning your batteries get a smooth, consistent charge that allows your golf cart to run at full strength throughout a round of golf. It also prevents early battery wear by avoiding things like undercharging or overcharging, which can shorten battery life and reduce driving range. Keeping the charger clean and free of dust, dirt, and debris, and making sure the cables and connections are secure, helps prevent overheating, charging interruptions, and other issues that can affect how your cart performs on the course.

Can I use a 36 volt charger on a 48 volt golf cart?

No. You need to match volts to volts. If you have a 36V system, you need a 36V charger. Using an improper voltage will cause damage to your batteries.

When is a 36 volt golf cart charger used versus a 48 volt charger?

36-volt chargers are used on older or economy golf carts that run on a 36V battery system. These carts typically have lower top speed and torque compared to 48-volt golf carts.

48-volt golf cart chargers are used with golf carts that run on a 48V battery system. These are typically newer golf fleet vehicles that offer slightly higher speeds and better performance on hills.

What does CEC Compliant mean for my golf cart charger?

CEC compliance means a charger meets strict California standards for energy efficiency, safety, and reduced power waste. Choosing a CEC-compliant model ensures you’re getting a newer, more efficient charger that meets modern regulations. Battery Mart carries several CEC-compliant golf cart battery chargers for sale.

How does Dual Pro Chargers outperform other Golf Cart Chargers?

Dual Pro chargers are the only chargers that will consistently and safely recharge batteries to a 100% level.

The end result is better performance, endurance, and longer service life from your golf cart batteries. Other points to consider are:

  • Carts can travel 5-10 miles further with each charge, depending on conditions
  • Through better management of specific gravity, battery life is extended by 25%
  • Easy to use "Plug & Play" technology - Deltavolt's intuitive technology does the work
