Hi guys,
This community has been great at providing valuable tips in the last few days since I've joined. Thank you. I greatly appreciate it. I am watching a video about LIFEPO4 batteries posted by one of the members to learn more about them.

Question #1:
I'm a total beginner to LIFEPO4 batteries and I'm having a hard time pinning down definitions for some of the common terms. The specs for my battery are next to the term.
Nominal Voltage - 12.8 = ?
Voltage Window - 9.2 – 14.6V = ?.. my guess is that this is the range of voltage the battery can have. and the voltage is an indicator of energy remaining.
Charge Voltage - 14.4V = ? ... my guess is that this is the voltage at which the battery should be charged... but maybe its the voltage when it's fully charged?
Standby Voltage - 13.8V = ? ... no idea
Max. Continue Discharge Current - 100AH
Max. Permanent Discharge Current - 200A 2 seconds
...
Question #2:
I'm trying to figure out how to determine if my battery is charged. I have it plugged into a Progressive Dynamics PD9145ALV 12V Lithium Ion Battery Converter/Charger - 45 Amp. It charges at 14.6V @ 45 amps. My battery has been sitting plugged in and I've been taking voltage readings for the past few hours (while it's charging).
For the last 2 hours, the battery has been sitting at 13.71V while it's plugged into the charger (and charger is on). There has been NO CHANGE in voltage in about 2 hours. When I unplug the charger, remove loads (no loads anyways) and take readings 1 hour after unplugging from charger, the battery indicates a charge of 13.35V.
From LIFEOPO4 voltage charts (ones on this forum) 13.35V is about 90-95% charged but my battery never achieves 13.6V (with no load and tested using multiple instruments).
The battery is an expertpower 12V 100AH battery, this is all they provide as far as specs: https://cdn.shopify.com/s/files/1/2364/9089/files/EP12100_v2_100A.pdf?v=1610472867
