I have a Cyberpower 1500 UPS attached to my Harman Advance that will give me 15 minuets run time on the supplied battery( 7 amp hour?). I also have a generator so If I am home I can hook It up If we loose power for an extended period of time. I am trying to cover all the bases and want to extend the run time so If I am away from the house for an hour or two and have a power loss I will be able to get home and run the generator. I have seen 100 amp hour deep cycle batteries that will do the trick for like $300.00. But before I spend that amount of money I am trying to figure If I could hook up an extra lawn tractor battery to do the job. The battery I have is a 12 volt 230 cold crank. For the life of me I cannot figure out how to convert amp hours to cold cranking amps. .Any help with this question will be appreciated.If I ruin the battery by doing this just one time It Is ok as Its an extra. I need about an hour more run time.
Thanks
