Can this be charged (feddit.dk)

I replaced this battery last fall, but it has drained over the winter. The auto-mower dock wont charge it. Is there any feasible way to charge it safely? Or is it dead at that voltage? It’s a Bosch Indego 400. Thanks in advance.

I have a cheap power supply which can be limited in current and voltage and I've been able to revive many such batteries with it. I use it as a drip charger limiting current and voltage so neither gets too high until the regular charger picks up the battery again.
