What model? I realize that seems dependent on the manufacturer, but is there an easy way to identify a proper battery?
First stop, Costco.

 

Will this do?
EverStart Maxx Lead Acid Automotive Battery, Group Size H5 - Walmart.com

 

Its strange it doesn't show any AH rating, it will need to be 65+?

 

No, I guess it doesn't. Is that important?

 

Yes the AH rating is its power so you will need 65 or greater for that engine. Some larger are fiscally bigger so need to measure the battery carrier if it will fit.

 

So I bought a new battery with the sole intention of running my car for a couple of minutes each week.
There is a potential "draw" with my electrical system so I don't want to leave the battery in the car. IT was suggested to bring it indoors and place it on wood (or anything not concrete).
But I get conflicting information. One guy said a new battery will last about a month, even unattached to the car. Another said about 6 months.
Any idea?
Also, how to check for a draw?

 

Its hard to say how long they last without being used. New batteries are dry charged so you just add electrolyte to activate them. A battery needs to be charged and discharged at the correct rate to keep the plates from becoming sulphated.

 

Thank you keithuk. If I gave you the brand/model, would it give you some idea?

 

Not really, that's the same for all lead/acid batteries.
