Thinkpad T470 “Critical low battery error”

Last week, when I tried to use my thinkpad, it wouldn’t wake up from sleep mode. I let it discharge its battery completely, hoping it would work after. The next day, I plugged it in, trying to turn it on, but it said “Critical low battery” and then it just turned off. My question is, would it be safe to try to charge it or would that damage the battery even more?
