I assume that if I change the battery every 4 years any AGM battery that fits will be ok. Any battery brands that I should avoid and any that I should favor?
Often batteries that are on sale are batteries that have sat on the shelf too long. Check the date on the side of the battery casing and check the label that says when it was last charged, that label can tell you if it has the original charge still or been recharged.
Make sure it comes with at least one plug, preferably two in the ends of the top part of the battery. They are in.vent holes, one goes to an overflow and the other is plugged to stop acid getting on your car.
