Even a brand new battery can be defective. Not a super common thing, occasionally it does happen.

So easy option #1 is take it back to where you got it, or to might near any auto parts store where it can be 100% tested, Normally this is a free service. This will rule this in/out as the problem.

But as suspected, something to do with the vehicle might be the problem.

This would be Option #2 ( a bit more involved for you, but more expense, if dump it off on a shop). Attempted DIY, is not hard, It may take time, may need an assistant, and of course we are here to help if necessary. We have access to Mitchell/ Prodemand and can pull up wiring diagrams. Once you find a suspected circuit, we may be able to tell you how to narrow it down further.

I am sending you a link that may sort of shows you just one (of many) possible things that can drain your battery. This may sorta get you motivated! See my answers in the link.

Now you need three things:

An assistant,

A cheap meter (Harbor Freight has a decent digital voltmeter for about $5.00 auto stores a bit more), And finally, Go to "You Tube" look up "Parasitic Drain"(there will be many). View several videos. Some explain better than others, some show using different meters to figure it out. Some are more professional.

Find one that is comfortable for you to go buy.

Return here with News/ diagnosis so far/ the Need for information from us.
