Once the battery in my SG5 is fully charged (battery registers 4.15w on multimeter) and I disconnect from the external power source, the charging indicator light stays red which progressively drains the battery over a period of time. How do I turn the red light off to keep the battery fully charged until I use it in the golf course again? Thank you.

Chances are that your battery doesn't / wouldn't hold a charge anymore. The laptop runs off battery power. When it is plugged in, the AC power "goes right through the battery", to support the laptop's operations. When the power cord is unplugged, and the battery doesn't hold a charge, the laptop will shut down, as your battery is (too) low to continue supporting the laptop's operations.

The easiest way around this problem is to get a new battery for the laptop.
If your battery is (quite) new (and a Lithium battery), you may wish to see if you can "revive" the battery's "life" ... first by depleting the battery (completely), then charging it (until it shows it is full, plus a couple more hours), and repeating this process a few times. If you're lucky, the battery will slowly/gradually start to hold some charge, but, don't expect it to be very long.
The (preferred) way to use re-chargeable batteries is to charge it fully, unplug it from the external power source, use it until it is depleted, then plug in the external power source to charge it up (fully) again .... and NOT to keep it on a power source all the time.

I would say a dead cell in the battery

How do you know that batteries are fully charged? If it won't power up then the indicator won't tell you their level. Pull both batteries. Push the power button (using what minimal power is left anywhere in the system.) Plug the camera into the external power source (mine has a base that will charge your battery, and supplies a cord for power to the camera.). If it still doesn't power up with the external power source, then I would say there's something wrong, but I'm betting it's the battery/batteries.

Bike has magneito (thats spelled wrong ) On line youtube veido shows how to fix that.

Hello there,
Since you have tried charging the device using the usb and the power cord. It is quite clear to know that the problem is from the device connection port. It is bad and need to be replaced.
But you need to Try to test the battery in other devices then try to charge it there to see if it will hold a charge. If the battery holds a charge there, then it means the battery is okay and if it does not charge. Then it means the problem is from the battery. It need to be replaced if so.
Then test the charger/ power cord on another device if it is not bad, then you test the usb cable also. After running these test. You will be clear to know if it is the connection port. Then replace the connection port once confirmed to be the problem. Hope this helped. Goodluck Elect_Comp

Replace your battery to solve this trouble.

If you follow these instructions which I think you know how to, it will recharge. If not the rechargeable battery needs to be replaced

To charge the battery, simply follow the steps below:

1. Gently pull back the rubber cover to gain access to the mini-USB port located at the bottom of the SkyCaddie. Insert the mini-USB connector of the supplied wall charger into the mini-USB slot.
2. Plug the wall charger into the AC wall outlet. While charging, the charging indicator in the upper left-hand side of the SkyCaddie will show red. The charging indicator will switch to green when fully charged. You may also notice the unit's screen turn on and off periodically.

The battery will charge, even with the SkyCaddie turned off. A full battery charge may take 4 hours. Once fully charged, expect 36 holes of continuous play.


Warning!Always connect the cable to the SkyCaddie first before connecting to AC power or PC USB.

If it shows NO external source, then this is most likely the best place to look to find out why not?

The Biggest problems with Inverters is Flat/Low/Bad batteries, Sometimes it pays to remove the batteries and charge then up remotely, and then replace them, fully charged, Now a fully charged 12 volt battery should have 13.8 V DC at the terminals with NO LOAD. If the battery only reads 12 V it is not properly charged.

Issue with your Power Supply... Or Battery Need to be replace .

battery may show fully charged while charging, but it can noot hold the charge. So you need a new battery. If under warranty ask Verizon for replacement.
