For BFL13 et al... FLA vs AGM vs Li vs heated Li

Inappropriately high temperature degrades battery longevity with an alarming acceleration.
Here's a rude, crude, dangerous, but understandable example...
Stick a finger in a beaker of H2S04 sulfuric acid then extract
At 40F the acid will start to burn the skin as it heats up
At 120F you don't want to know. Yes it is that ugly.
It's the same with caustic soda.
This is why I wash lead acid battery corrosion with baking soda, boiling hot water, gloves and goggles. The amplification is to say the least, dramatic.
It is in the best interest of any battery's longevity to have it live in the lower 1/3rd of its Goldilocks' zone
The highest performance is gained in the highest 1/3 of its Goldilocks zone.
Temperature compensation is critical with any battery.
But realize as upper and lower temperature thresholds are approached the voltage and amperage limit issues are not yes/no black and white. They are graduated in effect.
Temperature values taken at electrical post connections give a good clue as to what is happening in the interior. Thermal conductivity is related to electrical conductivity because of electrical conductivity. Pathways are high amperage. Excessive temperature differential between cells is an emergency grade shutdown alarm.
