I was going to buy a new battery for my Cali my wife recycled the one I removed. I went to the battery shop and they said I needed the ES-TX30L but the form factor did not look correct The Auto parts store said I needed a ES20LBS the internet battery finder said I needed an ES-30LBS. The ES20LBS looked like my previous battery but the picture of the ES30LBS looked similar. A fellow Guzzi rider said the ES20LBS was for an 02 and the ES30LBS was for an 04 Does anybody have any battery recommendations?
