You can leave them connected.

If you get him going, take him to a popular auto parts store and have the battery and charging system tested. This is normally a free service.

This might help you too, before you buy anything!

Yes!

All seems good as far as home testing!

Get it fully/ thoroughly checked at an auto parts store
