How do you know the battery is fully charged?
Can't remember the color of the led light but when it's charging it's a color and when it's fully charged it's a diff color.
One of the batteries is only charging at 7.5v and is blinking blue or red. What's the problem?
Please reach out to Amazon and request a replacement.
I need the battery to fit in the same space as an alkaline 9v.
45mm high, 25mm wide by 17mm deep. These are very close to the size of a standard alkaline 9v battery.
Is it possible to keep it on the charger while I use it?
It will never fully charge like that, but the battery will discharge once you plug it in.
How long does it take to charge, where is it?
It will take about an hour and a half to fully charge the battery with a 5V/1A plug.
