Battery Power for fans
Battery Power for fans
(OP)
I need to run different fans at room temperature for approx. 12 hours at a time and need them to be run by battery power (the smaller/lighter the better). Can anyone advise me on what type of battery I need.
Type of fans:
i)12V, 0.38A, 4.56W
ii) 12V, 1.1A, 13.2W
Regards

RE: Battery Power for fans
The lightest battery per watt-hour will be a NiCad. I'm not sure about smallest size per watt-hour. They can be a nuisance, though,as anyone who hassome knows.
You will need to know the operating temperatures and duty cycle for these fans.
RE: Battery Power for fans
The reason for the over size is to avoid discharging the battery to below 25% capacity which would greatly shorten the life of even a deep cycle and isn't good for any battery.
