The ammeter on a 36-volt charger should show at least 15+ amps when the charger is plugged into the golf car, even if the batteries have not been used for a short while. A 15+ amp reading shows that the charger is actually charging, not just humming (humming is NOT an indication that the charger actually works).
If you have a 36 volt system with 6 volt batteries, you’ll want to see readings of around 6.2 to 6.3 volts per battery (37.2 to 37.8 total volts). If you are showing something like a 4 volt charge on a 6 volt golf cart battery, you have a bad battery and will want to replace it.
How many amps should my 48v golf cart charger show?
48-volt golf cart batteries can be arranged in different ways. A 48-volt system of 4×12 volts can deliver approximately 600 amps. Yet a 48-volt system of 8×6 volts can deliver 1,800 amps. This alone can increase the range of a golf cart from about 12 miles to about 35 miles.
How many amps should a golf cart charger put out?
Most golf cart chargers will charge at 10-20 amps. If you have a 220 amp hour battery and are charging at 15 amps, it will take about 14 hours to charge.
How do I know if my golf cart charger is charging?
Turn on the battery charge to see if any power is getting to the battery. You can check the amount of power the battery charger is generating by conecting a voltmeter to the negative and positive clamps of the charger. On the voltmeter is a needle moves from left to right to demonstrate amps present.
Does the AMP matter on a golf cart charger?
Any 36-volt battery charger should initially start by providing at least 15+ amps to the batteries. The amps may drop down very quickly if the batteries are fully charged but the ammeter should show at least 15 amps to start off.
How many amps do I need to charge a 48 volt battery?
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 48 volt battery pack would take about a 25 amp 48 volt charger (or less).
How many amps is 48 volts?
20.8 amps at 48 volts. 8.3 amps at 120 volts. 4.1 amps at 240 volts.
Can you overcharge a golf cart battery?
Overcharging your golf cart batteries may damage them. It is best to use an automatic charger that turns itself off when a battery is fully charged. Do not drive the vehicle until the battery dies; lead-acid batteries won’t last as long if you completely discharge them.
How many amps should a 36 volt charger put out?
A medium amp output 36 volt charger would be in the range of 10 to 15 amps or so, and be used for many applications using about 100 amp hours of battery and up, or applications with a constant amp load (power supply application).
How long should it take to charge a 48 volt golf cart?
Depending on your batteries condition, it shouldn’t take you more than 6 hours to completely charge a 48 volt golf cart. It is advisable to go for a 48 Volt fully automatic battery charger that can do an overnight charging.
How do I know if my battery charger is working?

- Plug in your charger to an electrical outlet.
- Turn on your voltmeter unit.
- Take a battery or battery pack that’s compatible to your battery charger.
- Check the readout on the voltmeter and see where the pointer is indicating to.
How many volts should my golf cart battery read?
Healthy batteries will indicate about 50 to 52 volts on the voltmeter. Most battery packs hold around 48 volts. Keep in mind that the high number doesn’t mean that the batteries are instantly good. This measured value doesn’t take the load or cart’s power consumption into consideration.
