Dead Cell, Should I Trash The Battery?

[BRICH1260]

In the process of boat winterization, I removed both batteries and have taken them into my garage. After charging both batteries, I noticed my deep cycle battery has a dead cell. Checked by a hydrometer, all balls sank from that cell, while in other cells all balls floated. The battery looks fairly new and has a tag of 10/10 on it. I don`t have the receipt as I just purchased the boat used this year and it was with it.

Can anything be done to revive this cell. Should I just pony up and buy a new one or just continue to use this one till it fails completely? It is a #2 battery, used primarily to power the stereo while at anchor.

Wait untill spring and replace the battery. If the cell is dead it will just leave you stranded. I would then use the new battery as the #1 and the other one as #2..

I think Birch is saying his #2 is a deep cycle not a cranking battery. Best not to use his #1 cranking as a #2 deep cycle.
