Check if all cables are plugged all way in battery is charged to 100% when there is green light on charger is display on or not check battery voltage when it is fully charged!

The only way to know is to measure the voltage on the battery terminals, which should have been done before contacting the seller. You did remember to switch the battery on, right?

Downtube UPP battery on a kit bike? Check your wires from controller to the battery cradle. If you soldered your own connector, look at your work.

Also look at where the battery connects to the cradle pins. A long time ago, I had the connector on the battery side get unscrewed and it fell into the battery. No power connection,
