Ok ive never been right into amps, volts and the like so be nice.
How long will an item that uses 1.1 amp last on a single 12 volt battery??
How many amp hour is the battery.
Have a read of this chart!
Cheers,
Leigh (Kero).
Cold cranking amps 800
Reserve capacity (in minutes) 137
Amp hours (20hours) 82
If you can tell me what all that means it would be great.
cheers
When that design of battery was made it was put under a load test for 20hrs.Originally Posted by wayno60
Eg: 82ah divided by 20 hrs = 4.1 amps [till dead flat]
Theoretically you should be able to run a 1.1 amp current from it for 74.54 hours [till dead flat]
But be aware batteries should not be completely run flat, as a general rule 50%, so around 35 hrs run time.
There are other factors like Peukerts Law

Cheers mate, thanks for the help.
and thats without any charging inbetween.?so around 35 hrs run time.
Correct, but some points to note
as the battery gets older these figures will diminish.
charge back up asap [with a good charger]
dont expect it start your motor if you run it to low
got it........
So to run it for say 6 to 9 hours with some motoring around, no need to worry?
