Yep those will work too. Sometimes the build up is so hard that you need to scrap it off. You can probably scrap quite a bit off before you have issues. Replacing the terminals are pretty cheap too. But honestly I haven't thought twice about scrapping them, there are probably less abassive options like you mentioned. If a toothbrush combined with a cleaner or baking soda works, that is a very good method. Thanks for sharing 👍

@@thebestfamilyoutdoorshow thanks, I have been having issues keeping my terminals tight because some clamps have reached tightening limits. Seems battery connectors are made of soft lead. Auto stores also sell caps that allow tighter fit. I'm looking for minimal maintenance to save time. Continued blessings

Yes Costco will either pro rate the battery or give you can exchange if it is within warranty. In my experience, Walmart (I bought Energizer and Everstart brand before) and Costo (Kirkland brand) are about the same price and quality for the 12v batteries. Both tend to last and die around the same time. I haven't scientically test it, but approximately.

@@thebestfamilyoutdoorshow ok thanks good to know since I usually get Walmart batteries since stores are everywhere.
