Ez Go 28115-G01 battery charger does not work.

All automatic battery chargers in the automotive market today have some sort of voltage regulation to prevent overcharging the battery. The rate of the flashing is dependent on the battery type, its rated capacity, the degree of discharge, its age, the temperature, as well as the amperage rating of the battery charger.

If the charger's green LED begins blinking when you connect the charger clips to the battery, the amperage in-rush current to the battery is reaching the pre-set shut-off voltage and the charger is shutting down. The voltage will drop as soon as the charger shuts down, turning the charger back on. This may also mean the charger has detected a battery problem - for instance, its ability to take or hold a charge. Sometimes a battery may be sulfated (accumulation of lead sulfate on the battery plates), and the sulfation is creating a high resistance to the current flow (ability to accept a charge). Or, perhaps the battery is deeply discharged (below 8-volts).

* Like a 12VDC auto (car battery) charger? No. It does not have enough voltage to overcome the initial surge (about 20-22 volts)
* If this is a Lithium Ion pack the it should be putting out a minimum of 16 Volts DC to a maximum of 21 Volt DC.
* The battery (or charger) also needs to monitor the temperature of the batteries, Charge voltage, and Charge rate. This is to prevent over charging and over heating.
* Just slapping a charger on any multiple cell battery pack will destroy it if it's overcharged (over heated).
* If you do have a charger but the charger won't recognize the battery then it may be possible to give it a "boost" with another full charged battery (has to be the same type). This is where you connect the batteries in parallel (Positive to positive, negative to negative.) Let it charge for a short time 15-20 seconds should do it. Try the charger again.

* Using existing charger to fix battery (does not always work); https://www.youtube.com/watch?v=6GfPKg05ZIU
* If your using NiCad batteries then you will have to "Zap" the battery (This is a bit hazardous); https://www.youtube.com/watch?v=5B9rx7hoizk
* I think the earlier video guy had the right idea. Just turn in the bad ones and get new on (or at least Lithium Ion batteries)

But the cart still wouldn't fully charge. After charging the cart, I checked the voltage on the entire battery pack using my meter and then each ... 36 volt powerwise ez go charger not working

If the scooter in question is a Pride Victory with on board charger ? ( you plug a mains lead into it ?) now what happens with this particular scooter as the charger starts to fail, it's not charging the battery correctly, if you have access to a multimeter DC setting , check the voltage from one of terminal of the battery to the other terminal of the opposite battery, now it should read at least 18 volts , 0 volts then you need to change from one terminal to the other and same for the other battery ,, now if it below 24v that's the problem because as soon as you put it under load the voltage drops to under the minimum working voltage for the controller , hope that makes sense so other-words you need to replace the on board charger , contact me and I show you a way to do this cheaply...

you had to plug it in the charger for a while and then you hel the power button for more than a minute

if it not work hold power button and volume up for 20 sec.

These will help.

Thanks.

PLEASE NOTE: The Low Voltage Protection feature on this battery charger will not allow the charger to activate unless it is connected to a battery pack that has a minimum voltage of 16 volts. Battery packs with voltages below that level of charge cannot be recovered or recharged. This is a safety feature to prevent overheating in the event of a faulty battery. This battery charger will not output any voltage to the XLR connector until connected to a battery pack meeting this minimum voltage requirement.

Your batteries have died. The reason it will barely move in reverse is that current is being supplied to the motor is a direction that it spends very little time using. There is a slight change in the armature over time, and reverse tends to work better over time. Check the voltage when under load. (run jumper wires from the + and - of the battery bank. If it is a 36 volt cart and the voltage drops to below 36 volts, you do not have enoug current to run the cart. Plug in the charger and watch the ampmeter. If it goes up to about 20 amps, then it is charging. It should take a good charge after 10 hours. If the cart charges and only runs a short distance, the batteries need replacing.

most modern chargers have "smart chips" to control the charging process and prevent overcharging. if the voltage falls below a pre-set minimum the charger will refuse to charge the cell(s). assuming the cells are all good (which you should never do!) i'd give them a boost with a "dumb" charger like the ones you get at the dollar store that go in your cars cigarette lighter and is designed for a cell phone. do this at your own risk and be sure you don't reverse polarity! i give you this tip assuming you're cautious and knowledgable - don't blame me for any accidents. this *IS* a risky solution.

I just had this happen to mine too. I think this is a design problem with the camera/battery combination. My camera has a lithium polymer battery (most do now). Lithium polymer (lipo for short) batteries should never be allowed to discharge below about 2.75 volts. Letting the battery discharge below that level will actually permanently damage the cell.

In order to keep that from happening, the device that uses the lipo should have protection circuitry that prevents the battery from falling below that level. I think this is where the Casio camera may have an issue. I found that if I left the battery in the camera for about a month, I was not able to charge it! Lipo battery chargers are more sophisticated than typical charges because lipos need to be charged in a specific way. The first thing a lipo charger does is to check the voltage of the battery you insert into it. If it is below a critical minimum voltage, it will not even charge the battery (Casio charger blinks red continuously).

There are a couple tricks you can do to get the battery to charge, but that's not the important thing here. I think Casio needs to address this issue with our cameras. It would be nice if we could just update the firmware in the camera, but I'm not sure we can do that. I intend to contact Casio to see if they know anything. Based on how many posts like this I have read, I bet they do.

Good luck to use all.
