GTmedia V8 Finder Pro 2 battery

Hello, I have a problem with charging the battery; it won't charge. The device only works when connected to an adapter.

My Finder Pro (1) came with a 9 volt charger.

The issue I had was that charger has a Type C USB connector, but is ALWAYS 9V.
I used it on other things and killed them as it was NOT 5V.

If you use a normal 5V charger the battery will not charge, but the finder will run.
For a while I was charging my Finder pro battery in another model finder- meter V73 as it would not changer in the finder pro because I was not using the charger that came with the finder, that 9 Volt Type C plug charger.

When I found how I was killing other USB things I stored away the charger and now can not find it.

B dangerous charger that looks like a type C charger, but is 9V and kills things that only want 5V.
If you have the same charger, put red tape around the plug end so you do not use it on other things.

The charger that came with the device is 9 volts and the battery isn't charging. Could this be due to an update?

If you left it un used for some time, like 6-9 months, the battery is now likely dead.
I have found that the GT Media finders use a very small amount of power from their batteries even while powered off.
This will flatten and kill the battery.
I re charge mine every three months.

Watch if you fully discharge the finder.

The problem is that the battery in a device I just bought shows 8.48 volts when I measure it.

The finders do have a function in them that if they get flat batteries, they shut down and will not power on until they are recharged to a certain level.
Maybe your is not seeing that level, even when it is charged.

When you tested the battery voltage level, was it connected to the circuit board?
Is there battery voltage on the circuit board? Is the battery power plug faulty?

The voltage is the same when disconnecting and connecting the battery on the circuit board. It seems to me that there is a problem with some of the resistors, transistors, and capacitors. I am not a maintenance technician.

Upon inspection, there was a short circuit in Hadi. Is this the cause of the problem?
