If you buy one, get a brand name from local store - or an AAA/CAA membership and a phone  |
You definitely have to keep them charged.
Lithium batteries in particular don't handle that kind of discharge, a single run-flat event can kill them entirely. Even if it doesn't, it will absolutely damage them, so they'll never have the same capacity again and will have reduced lifespan.
