Battery Charger Troubleshooter
When there is a battery failure, there is a possibility it was caused by a bad battery charger. When the charger is only plugged into the wall, it should show a green light. If there is no light showing, confirm that the outlet is good. If the outlet is good, it is very possible that the issue is with the battery charger, not the battery.
If the charger is plugged into the battery only, it should show a green light. (If you have purchased a new charger within the last year, you will not get a green light if the charger is only plugged into the battery. You will get a green light however if the wall charger is just plugged into the wall and not plugged into the wiring harness) If it does not show a green light, it is likely that the charger is not making contact with the battery. The most likely reason for this is a faulty fuse on the wiring harness. This fuse is a 2-amp automotive fuse, and it should be replaced with a 2 or 3-amp fuse available anywhere that sells auto parts. The fuse can blow out if there is a short in the charging system, or if the plug-in end of the wiring harness comes in contact with a battery terminal.
When the charger is plugged into both an electrical outlet and the battery, there should be a red light showing on the charger. A red light showing indicates that the charger is in contact with the battery and is actively charging the battery. Once the battery has reached a voltage level that is considered "fully charged" the red light changes to green. If after 24 hours the light has not changed to green there is no cause for alarm! Remember that when the light is red, the battery is being charged, and you will be able to use your system. After 24 hours or so, your battery is as charged as it is going to get, and if the light is still showing red you should disconnect the charger and go fishing. Replacement chargers and parts can be purchased directly from MarCum's website.
If you are really concerned about your battery, consider getting a basic volt meter to check the voltage of your battery. They can be bought for less than 20 dollars and will show you exactly what the voltage level of your battery is. If after 24 hours of charging your battery should have at least 12 volts (ideally 13-14 volts) and as long as it is over 12 volts it will work. If it is not at or above 12 volts you should consider replacing the battery. If your unit starts to malfunction while you are fishing, it would not come as a surprise that the voltage has dropped down to 11 volts or lower.
If the charger is plugged into the wall and battery, and you get a blinking light on the charger, it is very likely that the battery is faulty and should be replaced.
Batteries are an expendable item, and must be replaced periodically. Any store that sells ice fishing electronics will stock suitable batteries. You can also buy them at a specialty battery store, or by ordering one from our website.The batteries that you should use are the "Sealed Lead Acid" variety, they are 12 volts, and range from 7 to 9 amps. The more amps the battery has the longer it will run on a full charge. Your MarCum unit can be powered off of any battery that is 12 volts, even a large automotive or deep cycle batteries will work.

Check the battery with your multimeter. If it reads below 36 volts (or whatever the cutoff point is) it may be damaged. But before you run off and buy a new one, use the multimeter to check the voltage from the charger.

Or borrow a good battery and see how your charger behaves.

that way, you can identify the cause of the problem

If your TVBP-BTN wireless stereo headset is not charging properly and the blue light is not showing, there are a few things you can check to fix the problem.

1. Check the charger: Make sure that the charger is functioning properly and that the connections are secure. Try using a different charger or USB port to see if that resolves the issue.
2. Check the charging port: Make sure that the charging port on the headset is not dirty or blocked. Clean it with a dry cloth if necessary.
3. Check the battery: Make sure that the battery is not damaged or dead. If the battery is damaged or dead, the headset will not charge.
4. Check for software updates: Make sure that your headset's firmware is up to date, if there is any updates available, install it.
5. Check the manual: Check the manual that came with the headset for any troubleshooting steps or contact the manufacturer for further assistance.
6. If you have tried all of the above and the problem persists, it may be a hardware issue, and the headset may need to be repaired or replaced.

It is possible that there is an issue with the battery or the charger itself. Here are some possible reasons why your charger may be jumping from the charging light to the green light in rapid succession: Battery Compatibility: The charger may not be compatible with the specific battery you are trying to charge. Double-check to make sure that the battery you are using is compatible with your charger model. Battery Health: The battery may be damaged or defective. Try charging a different battery with the same charger to see if the same issue occurs. Charger Issues: The charger itself may be malfunctioning or defective. Check for any visible damage or loose connections. You may also want to try cleaning the contacts on the charger and battery to ensure proper charging. Overheating: The charger may be overheating, causing it to switch rapidly between the charging and green lights. Make sure that the charger is in a well-ventilated area and not covered while in use. If the issue persists, it may be best to contact the manufacturer or seek assistance from a professional technician to diagnose and resolve the problem.

The charger is damaged. Return it to the place of purchase and demand a refund or replacement. If you paid by credit card call the credit card company and cancel that transaction.

If your Power Wheel Chair has been sitting idle for a while, the batts may need to be completely replaced. There is a gel inside the batts that need to have a current run through them via the charger on a regualr basis otherwise it will solidify. If the charger lights are onm you have connected the charger correctly for over 24 hours and the batteries are still not showing they have been charge, there may be damaged cells which means both batteries need to be totally replaced.

most likely your charger port is damaged, if you try another charger and get the same thing- then I am sorry but the phone is finished. warranty does not cover damaged ports, but if you have the insurance it is covered under damage, if its lless than a 30 day old problem. If you replace it with the same phone, discard any chargers you used on the old one.

the charger might have the problem, and the light that you are seeing apart from the light next to power/battery is the hard disk led, this is showing that HDD is active, your motherboard is not damaged. you might want to check if you need to defrag the Hard disk by right clicking my computer then selecting manage, there you may analyze whether it needs to defrag. now you may check the charger if its chrging by clicking in the taskbar.
