Dear Sir/Madam,
I have a 9V 800mAh rechargeable battery, this battery can constantly provide 9.18V all the time. It is a USB rechargeable battery. If I plug it to a USB mobile charger adapter, I measure the adapter providing 5.04-5.07V and 450mA to charge the battery, may I know how much of time the battery be fully charged? How to calculate the estimated time?
Best regards,
Kelvin.
