Good info TB, and thanks.
I have yet to fully deplete my 100 ah LiFePo4 Battle Born. I have seen the voltage drop to 13.1 and just hang out there for hours with a modest load, then recover to 13.2 when the load is removed. It has been able to recover quickly with a generator/charger combo the next day, multiple times.
It is currently in standby as I slowly get other things done, but I know from experience that all of my drone flight batteries, and my e-bike battery, can contain a lot of energy and seem to hold up well over time.
I would generally assume that all of these batteries experience capacity fade over time and usage, but the fade is gradual, so its hard to notice in daily use, until you get to the end of life, and it just more or less quits. Electric vehicle lithium batteries tend to do this, as the maximum range of EVs slightly decreases over time and number of charge cycles.
The difference, in my experience, and as I see it, is that lead acid batteries, as they age, take LONGER to charge, and return less on discharge, where the lithium chemistries, as they age, take LESS time to charge and then return less as they discharge.
Is this what you have noticed?
