Unfortunately, we do not offer global warranty on our products.

We do not sell the battery separately. If the battery has a charging problem, please try to purchase the same type of battery specification from your local electronic/phone/camera store.

Since it is still in the 30 day return period for Amazon, we suggest you return the defective unit to Amazon for exchange/refund. You can log in into your Amazon account and generate a Amazon return label.

The indicator light would light up and turns off after fully charged.
The battery power icon will appear on the bottom left of the LCD screen.
If you charge it for a few hours, but run out of power quickly, the battery is broken.

Unfortunately, we do not provide technical manuals to end users, you can contact customer support for assistance.
