It would be better if we use the OEM FRU number as seen from parts lookup page using your serial number.
L09S6Y02 is more of a battery manufacturer specifications.
We cannot guarantee that the BIOS would smoothly identify it as it has to be an OEM battery so checking on return option is suggested if you decide on this.

Yes, 121001091 is the OEM part number that you can use to order the battery.
As per the original issue " 0% available (plugged in, not charging)", we were able to arrive at the conclusion that you need to replace your battery as the wear level now at 98% with full charge capacity only at 1020 mWh from its original 38880 value.
Using the OEM part number 121001091, it would assure compatibility of the battery you are to purchase.
