Hello all,

If I was to use a 12volt heater fan on a 150 amp hour (leisure) battery how long would I get.. The fan uses 25 amps on full blast, but obviously that's over what is required as its heating a 110. I would expect well under half that is what is required....

Many thanks

Steve
 
If it's on full it's on full and will be using 25amps. I'll gie you a clue to the solution to your problem the xxx Amp/hr is the number of amps required to drain the Battery in 1 hr??
 
Just making sure there were no other factors involved like the battery melting or being damaged by being used at medium setting ie ten amps ?
