How to get your golf cart battery charger to charge dead batteries…
This is a scenario that happens a lot more than you might think. In the world of golf carts and our daily lives golf carts get left behind or neglected on a regular basis. When this happens the lead acid batteries in your vehicle drain down over months of neglect to the point the golf cart will not move or operate any longer because the voltage is so low in the system. So being we get calls all the time like ” How do I get my golf cart battery charger to charge my golf cart? The golf cart is completely dead…
The Issue – Old Style Golf Cart Battery Chargers Vs New Style Chargers
In the world of Golf Cart Battery Chargers only recently have the manufacturers come up with a solution to this issue. Old style chargers will only charge once then shut off. So if you leave for months unattended and do not unplug and then plug in again the charger will not charge the batteries again and over time these type of batteries drain down just naturally. ( At a rate of approx. 10% a month) Even faster if the golf cart batteries have a parasitic load on them from say a new golf cart light kit not installed correctly or a sound system like a golf cart Bluetooth sound bar. Though due to recent advances in charging technology you can now purchase a Smart charger for your golf cart that will basically baby sit your batteries while you are away on vacation for the summer or whenever. Just keep a new style golf cart battery charger like the new Lester Summit II Chargers plugged into your golf cart and it will do it’s thing. It will automatically kick on every 10 days to top off your golf cart batteries or if the voltage ever drops below a set number. ( Technically – I think that number is like 2.08 volts per cell. ) If you want to avoid this whole process I am about to explain in the future.

How To Make Electric Golf Cart Ownership Easy
Learn even more here with this great article on How to make life easier for the average electric golf cart owner. These are just a few basic tips and tricks I thought would be helpful for the new golf cart owner to consider and keep in mind.
Why Is Your Golf Cart Battery Charger Not Working
Ok… So the first guess or main reason why your golf cart battery charger is not working right now is because the batteries in your golf cart are completely dead. ( Not always but usually 90% of the time) This is because the federal government years ago made it mandatory that all manufacturers of these types of charging systems but a few safe guards into the device to avoid injury to you or another, electrocution or fire hazard.
Example – Your grandson ( AKA Dennis ) Finds grandpa’s battery charger in the garage and your grand daughter is bothering him somehow so he decides to start chasing her around the garage and shocking her by touching the connector on the end of the cord ( designed to be plugged into the golf cart ) to her skin causing harm.
Charger Manufacturers Mandate – All charging devices with an external connection will only be activated when connection is confirmed and a load or voltage is present to avoid possible electrocution or injury. ALL GOLF CART BATTERY CHARGERS MUST SENSE VOLTAGE BEFORE THEY WILL APPLY AMPERAGE!
So basically if the batteries in your golf cart are dead then the charger does not know it is plugged into a golf cart because it does not sense any voltage.
How To Get Some Electricity Back Into Dead Golf Cart Batteries
There are a few options in this process. The basic objective is to just get some energy back into the batteries so the golf cart battery charger can sense the voltage present at the charger receptacle and turn itself on again to charge the golf cart and the batteries completely. I recommend getting the batteries charged back up to their advertised voltage prior to plugging in the golf cart battery charger again. Depending on the size of the battery bank and the batteries. 6 volt, 8 volt or 12 volt batteries will determine how best to get that required energy back into them. Please note this process is a bit of a pain in the you know what but a valuable lesson to take better care of your electric golf cart. As letting the batteries go completely dead is very bad for the batteries and will definitely cut the life expectancy short.
In the golf cart business we use a golf cart battery recovery unit like BatteryPete’s Super Charger to jump start the golf cart in seconds or minutes to get the customers golf cart battery charger to kick on… It is kinda like a AED you would find in the airport or hospital to shock someone back to life after having a heart attack. At the push of a button you can apply a massive amount of voltage to a golf carts battery bank. Hence tricking the charger to turning on. Otherwise you can use a regular 12 volt or 24 volt battery charger for a car, boat or Rv to get some energy back into those dead batteries. More realistic as well because you or neighbor probably have one handy. The Heavy Duty Recovery Unit like the Super Charger run several hundred dollars but for the Golf Cart Guy it is a bargain because time is money and on average a service call will cost you $65-75 bucks… This device will allow him to put that money in his pocket in minutes and move on to the next service call or issue.
Most older style golf cart battery chargers require approx 75% of the chargers operating voltage present to activate. Others require a little less. So for example a 36 volt battery charger would require approx. 25-30 volts to activate, whereas a 48 volt charger would require 30-35 or even 40 volts present to activate. I recommend getting a digital volt meter out to start testing and checking voltage across the battery bank and the system in general. If you do not have one they can be purchased at any parts store, Home Depot or Harbor Freight for a few bucks… A volt meter is a valuable tool for anyone who owns a electric vehicle to check and test basic systems or doing basic diagnostics like this.

Depending on the Year, Make and Model or the golf cart you own will determine the best or fastest way to revive your golf cart batteries when completely dead. See some basic examples below that will cover most major makes and models..
36 Volt Golf Carts –
Systems comprised of 6x 6 volt batteries… Usually found in older golf carts across the board Club Car, Ezgo and Yamaha Brands but also Columbia, Harley Davidson ( Yep – Harley used to make a golf cart as they also made boats under AMF) other carts include Fairplay, Par Car or Western. For this system you will need either a 6 volt battery charger to charge individually by placing the charger connections on the positive and negative terminals of each individual battery. Or you can use a 12 volt battery charger and place the charger connections on the positive terminal of the first battery and then the negative connection on that of the second battery.
