Does hot weather affect battery performance?
I have four 12 volt lead acid deep cycle batteries in a vented metal box on the tongue of my Toy Hauler. We recently have gone through several days of 100 degree temps. Made me start thinking about...

First depending on the battery type keeping them INSIDE can lead to various levels of Disaster. Up to and including death by a couple different vectors.
Wet cells (Both flooded and maintenance free) most dangerous
AGM a bit safer
And LiFePo4.. well likely the safest but the jury is still out.
With the exception of LiFePo4.. I strongly recommend against indoor batteries. }
With those.. I do not recommend it but.. as I said jury still out.
Now to the OP's question:
Yes heat affects the batteries.
THIS article may confuse some so I'll summerize
Higher temperature means the battery can store more amp hours
But it also means you will need to replace the battery sooner perhaps in 7 years instead of 9)
Lower temps (Very low) are not good either
