FAQ:
Q: When to use a battery maintainer?
A: The main function of a battery maintainer is to keep a battery in top shape while it is in storage, usually for months at a time. While the battery maintainer is connected it routinely checks the battery, if it has discharged a certain amount, the battery maintainer would then start charging.
Q: Can I charge a battery with another battery?
A: yes, you can charge one battery from another if certain conditions are met. Current flows due to a difference in voltage, so the charging battery would have to have a higher voltage than the battery to be charged. The difficulty arises in that 1) as batteries discharge, their voltage drops, while the voltage of a battery rises while it is charged.
Q: What does a battery charger put into a battery?
A: A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol (how much voltage or current for how long, and what to do when charging is complete, for instance) depends on the size and type of the battery being charged.
Q: What is a dual battery charger?
A: The Dual Battery Charger with Battery for HERO4 allows you to charge two GoPro HERO4 batteries simultaneously. It is able to power from just about any USB power source – use the GoPro Wall or Auto Charger, a smartphone charger, a computer – even a USB backup battery.
