I did just find this additional information off the Lithionics website as this subject builds:
for the Lithionics 12V130A--G31-LRBM8
Maintenance: For optimal performance when in use, the battery should be fully charged to 14.4V at least once every 2 weeks. Fully charging the battery calibrates the state-of-charge percentage to be the most accurate and allows the cells to balance if necessary.
Storage: Storing your battery at the correct specifications is important as it keeps the battery in the healthiest state possible. Consult the table below for proper storage conditions.
Storage Temperature & Humidity Range:
< 1 Month -4~95°F (-20~35°C), 45~75%RH
< 3 Months 14~86°F (-10~30°C), 45~75%RH
Long Term Storage: If the battery needs to be stored for > 3 months, the voltage should be 13.2V (50% state-of-charge) and stored at the recommended storage specifications shown above. Additionally, the battery needs at least one charge & discharge cycle every six months.
Self-Discharge Rate ≤3% per month.
Typical storage example < 1 month: 1. Fully charge the battery. 2. Turn the battery OFF using the battery power button. 3. Keep the battery in an environment according to the specifications shown above.
Typical storage example > 1 month, up to 6 months maximum: 1. Reduce the battery state-of-charge to 13.2V, which is 50% ±10% state-of-charge. 2. Turn the battery OFF via the BMS power button. 3. Keep the battery in an environment according to the specifications shown above. 4. Every 6 months, charge the battery to 100% state-of-charge, then discharge the battery to LVC, then charge it back to 50% ±10% state-of-charge.
Powering the Battery Off Be sure to shut down any high amperage loads prior to turning the battery off. To turn the battery off, press and hold the power button for 3 seconds. The power button status light will turn off to confirm that battery power is off.
It also appears the Xantrex Freedom XC PRO 3000 inverter/charger does not lose its memory when DC power is removed per the Mfg
