Frequently Asked Questions About Your New Golf Cart Battery Charger

Dear Pete, Hi, finally this week we got the charger. However; once plugged to both the outlet and to the golf cart no lights come up, is this normal? Batteries haven’t been charged in a while. Confused… Terrific… Glad to hear you finally received the charger. Though in order for these chargers or any new style charger to function they need to be able to pick up voltage from the cart. If the batteries are completely dead or near so the charger will not kick on. You will need to charge the batteries up individually with like an automotive style charger, two at a time if you have a 36 volt battery system, or even can do 3 at a time if you have a 48 volt system and a automotive style charger that allows you to toggle charge voltage like 6v, 8v, 12v, or 24v. Once the bank of batteries is at least 35-40v plug in the new charger and it should do its thing. Regardless of how you do it the battery bank needs to be charged up enough for the new golf cart battery charger to know it is actually hooked up to a battery bank comparable the operating voltage of the golf cart charger you purchased. Once this is achieved should be able to use the new charger as intended. To get the most out of your batteries… Always charge your batteries back up after use and before storing. This is also the time to check the water level in traditional lead acid batteries. (After they are completely charged.) Pete
Pete… Super fast shipping thanks, Question? I received the new DPI 36 volt golf cart battery charger this morning. I started charging the batteries and everything was working fine. I came back to check if it had finished charging and the charger was hot, the amp meter was still showing close to 20 amps. I checked the battery volts with a volt meter and it showed 45 volts. I unplugged the charger from the wall outlet and disconnected the plug from the cart. I again checked the voltage and it was still at 45 volts. Is there something wrong with the charger or is this normal? These are new batteries and I don t want them ruined.   Yes sir…. All seems to be fine… These types of chargers do generate heat. Really any device that is passing and converting current (electricity) thru it will do so. That’s why they are made with Aluminum casings and have holes punched throughout the case to help dissipate the heat. New batteries right off the line are very hungry for energy and will soak it up like a sponge for the first 15-20 charge cycles… the lead is not cured yet… I have seen new batteries right off the line take a charge for 8-12hrs… usually starting out with amperage up around 15-20 range (Wide Open) then as the charge cycle reaches higher voltages the amp gauge will start to go down. but still might stay in the 5-10 range for hours still. These chargers are designed to shut off automatically when charge is complete so let it run its course… I do suggest venting the area if charging in a garage or shed vs out side because off gasing does occur during the charge process of lead acid batteries and kinda stinks. Note – a fully charged 36v cart is usually around 42-43v… but during the charge process as the charger forces electricity into the batteries the voltage will be higher. Same applies to a 48v system where there you will see voltages well over 50 volts… Hope this is helpful in better understanding your golf cart battery charger and batteries. Power On… Pete Just got my new golf cart battery charger in the mail. Super fast shipping but it doesn’t work either. my other charger just stopped working so I assumed it was the charger. Could there be something going on with my golf cart? The kids used it all weekend and ran it down to the point we had to push it into the garage. We plugged in our old charger and nothing. Here it has been a week and still cannot use our golf cart. Any ideas? Thanks in advance , Steve. Well actually you probably did not need to purchase a charger at all. Sounds like the batteries in the golf cart are just so low when you plugged in the battery charger it did not know it was plugged into your golf cart and just did not turn itself on. You see all new style chargers have to sense voltage before they will apply amperage. It is a built in safety feature so you cannot electrocute yourself or someone else once the charger is plugged into the wall socket. On average a charger will need a surface voltage of 30 volts or better in the golf carts battery bank to turn itself on. So if you do not have enough electricity in the golf cart batteries you will need to charge them up manually with a 6 or 12 volt automotive style battery charger. You do not even need to disconnect the wires just attach the clamps red to positive and black to negative on each individual battery for 10-15 minutes each to get some energy back in them. once you have done this across the whole bank. try your old charger first to see if it works. If so you can return the new one and we will credit your account minus the shipping costs to send to you. Hopefully this is the problem. It is a very common thing where people forget to charge the batteries in the golf cart before they go away for a few weeks. Or go away for the summer months to return to a dead cart. Pete…

How To Determine 12 Volt Operating Amperage For Your Golf Cart Voltage Reducer

If you own a golf cart and want to run other DC powered accessories you will need a golf cart voltage reducer. Most if not all DC powered accessories operate on 12 volts DC. That means 12 volts not 11.2v or 10.5v or any other number. Just 12 volts ( some accessories or devices will allow for a surge or drop in voltage momentarily but not constantly or consistently) The operating voltage for a device or accessory is exactly that  – “The Operating Voltage”. Otherwise the performance of  your device or accessories will be intermittent as is your voltage. You ever experience listening to a song that is having problems streaming due to a bad signal? The voltage a 12 volt accessory will need to perform optimally is no different. You just cannot see it sometimes as with the example of listening to the song will allow you to notice quite quickly. Clean voltage is required to operate any 12 volt accessory optimally and this is where a voltage reducer comes into play. Depending on your  needs or installed accessories on your golf cart will determine the 12 volt accessory systems operating amperage and ultimately determine the correct golf cart voltage reducer for your application.  Examples are things like Head lights, Tail lights (lights in general),Stereo systems, Cooling fans, USB chargers for your cell phones,  etc… So lets get to it! Really it is quite simple. You can just add up all the things you have attached to your golf cart that operate on 12 volts and find out the amperage draw each device or product pulls. Most lighting systems ( headlights-tail lights/brake lights) for your golf cart these days are LED light kits and require far less amperage to operate 5-6 amps at best. Where as older style halogen bulbs pulled a lot more (15-18 amps) As far as stereo systems go it will be determined by several things not just the head unit or stereo radio( Stereo systems with large amplifiers will require a lot of amperage and usually best to just install a totally separate high power Deep cycle 12 volt battery to handle the stereo systems needs.)  All other accessories like 12 volt plugs for a phone/USB charger will be minimal at best and should be able to use either 10 Amp, 18 Amp, 20 Amp or 30 Amp voltage reducers. I always assume the worst case scenario and want to make sure the electrical system can handle the surge of amperage required should all accessories be operated simultaneously within the vehicle or vessels system. It is always a good idea to keep a little extra reserve in place when it comes to the operating amperage of a circuit and not  to push up against the systems or devices limits. The golf cart voltage reducer you choose should meet the needs required and leave a little room in amperage capacity should you decide to add an additional load or additional accessories you might add in the future. The actual voltage reduction will be determined by the golf carts battery bank and current operating voltage. As in Gem cars, Polaris or Tomberlins use a 72 volt system, Club Car, Evgo and Yamaha run either 48 volt or 36 volt systems. Learn how to determine the operating voltage in your golf cart. If you already know the operating voltage you can now purchase the correct golf cart voltage reducer for your golf cart.

Save Time and Money with a Battery Watering System From BWT

Battery Watering Systems by BWTAn On-Board Battery Watering System is specifically designed for use in any application that has multiple lead acid batteries. They are very popular in golf carts. Though the Battery Watering system is not limited to just golf carts. Any golf cart style battery ( Traditional Lead Acid Batteries) also found in boats and RVs, Solar systems, electric floor sweepers and floor scrubbers and even pallet jacks. Based on the same technology as our industrial line of battery watering systems and valves this system is compatible with most battery brands. Crown, Deka, Trojan, US Battery to name the big ones…  The Pro-Fill on-board battery watering system works by replacing the battery’s existing vent caps with valves that are interconnected with tubing, allowing the user to fill all cells of the battery from a single remote location. Snap on/snap off water connections turn the often ignored task of watering batteries into a quick, simple task taking 30 seconds or less! Each valve independently shuts off water flow to the cell when the proper electrolyte level is reached, allowing the batteries to be filled perfectly every time without having to look at the batteries. Learn more about the advantages of installing a watering system on your mulit-bank battery system today. After installing your system you will realize other cost benefits including extended battery life; increased performance. Being able to fill your batteries without removing the cell caps will allow you to avoid things like battery acid burns, ruined clothing, and breathing noxious fumes. You can finally relax and rest assured with properly watered batteries the battery lasts longer and performs better. The average person does not even know they need to check or fill there golf cart batteries with water til it is to late and they need to buy new batteries. Once they do know they still don’t really know how to do it or how much water should be added and when to do it. You can learn more about proper battery maintenance here. One of the biggest problems is overfilling a battery. This results in loss of acid or technically speaking changes the specific gravity of the electrolyte(acid) in the battery and once this occurs you can damage the battery plates when charging. either way it equals loss of capacity and life expectancy.

Which Battery Valve Do I Need For My Battery Watering System

We get phone calls all the time asking “Which Size Battery Valve Do I Need For My New Golf Cart Battery Watering System?” So you will find below a few charts from Battery Watering Technologies covering the basic battery manufactures that offer Golf Cart Batteries. As you will notice most 6 volt and 8 volt golf cart batteries are using the longer arm (1.73″) VB-TBB valve. Only in a select few 6 volt or 8 volt batteries will you find they require a shorter arm length (1.46″) . Usually the VB-TBY valve is found in the 12 volt golf cart batteries. This is because the shorter valve is required in most 12 volt batteries due to the fact the lead plates take up more space within the battery case and come up closer to the top of the battery and individual cells.  These valves sit in each cell and floats attached to the arms move it up and down depending on the water level internally to determine electrolyte levels. If the valve arm is bottomed out on the lead plates it will always give a false reading that the batteries have enough water in each cell even though they could be totally empty or only half full. VB-TBY VALVE ILLUSTRATION DIMENSIONS   You will find below a list of the possible batteries you are currently using in your golf cart. Note – If you intend to replace your golf cart batteries in the near future either wait til you replace to purchase and install this system, be sure to replace the batteries with the same make and model so your battery watering system will still fit properly on the new batteries or do some research and go with a quality battery that will give you years of trouble free use and are readily available so when you do replace years down the road you are going to be able to find the brand, model and size you need.
