Frequently Asked Questions
How long does the Defender 2916 fan battery backup last?
The 7Ah battery lasts between 3.5 and 15 hours depending on speed. Higher RPM settings deplete the charge faster than low-speed modes.
Can I use the fan while it is charging?
The AC/DC circuit supports simultaneous operation and battery replenishment. Internal controllers manage the current to prevent overheating the 6V cell.
What is the charging time for a full battery?
A complete charge requires 12 to 15 hours of connected power. The built-in protection circuit prevents damage if left plugged in longer.
