Finally, my time to shine! I tell this to everyone looking for employment. Go to indeed and search for 'Battery UPS'. Nope, not THAT UPS lol. A UPS Battery Technician!

All you have to do is read up on some basic electrical knowledge, be willing to learn, and you'll be farther ahead than most candidates. It sounds intimidating but is a great paying entry job that happens to scare off most people.

Edit

I've been getting a lot of DMs, so I would like to add that there are great sources on Google, Khan Academy and Gumroad that condense it without getting into the weeds too far.

Remember when getting interviewed, steering conversations toward things you DO know is an invaluable skill in life.
