Optima battery question

[noteven]

Can an Optima yellow top battery be recovered from 10.9 volts state of charge in storage?

I have charged it with the 3 stage charger converter for 24 hours, disconnect and allowed to rest for 24 hours. Reads 12.2 volts. Connect the TC wiring to it - the only load I am aware of is the display on the stereo and the CO monitor. Voltage drops to 9.8volts.

Is this battery kaput?

It's mate was at 12.2 volts after storage, charged by itself for 24 hours, rested for 24 hours, and has sat at 12.66 volts for 3 days while I fiddled around with the other one. Does not change when connected to the camper wiring by itself as described above.

Sounds like it's gone to me.

Hi,

Pretty much it is a goner--but seeing as there is nothing to lose see if you can do a "recondition" charge.
