Battery help 2013 LX 570 (3 Viewers)

Battery help needed.

Replaced the battery a few months ago and it’s run fine.

Now it is completely flat, no charge whatsoever. I used a portable battery to jump it but it does 1 crank and dies again. The old battery had the same issue.
Thoughts or suggestions?

I did do a couple creek crossings a couple weekends ago but drove back a couple hours no problem and have driven the car a few times since then so not sure if it’s the alternator which was replaced 3yrs/35k miles ago at 87k miles.

Thanks!

Would definitely have the alternator checked.

Yes. And pull the door sill trim to check for water.
