So you're suggesting I bring that up to them if that's the case and say that I can't ship it.

Correct.

A leaking battery Is classed as a hazardous material.

And if that would be the case bringing it to a store (for another company like Target / Best Buy) would put me at risk of COVID or something of that nature which would prevent that as well?

This may never happen, but taking advantage of the COVID-19 situation, Is certainly a good thought under the circumstances.

Alternative to your suggestion (which Is very good by the way), you can say that you're currently In quarantine/lockdown, hence not permitted to leave your premises.
