What was done
We came out to your no-start and found the battery had dropped well below starting voltage after sitting through the cold snap. We replaced it with a fresh unit, cleaned and treated the corroded terminals, and confirmed the charging system is putting out correctly. Your vehicle started right up and is ready to go.

Recommended next steps
Your charging system checked out fine, so this was just the battery reaching end of life. Batteries typically last 3–5 years — this one is now dated, so you're set for a while. If you notice slow cranking again, call before it leaves you stranded.
Your reports will look just like this — in about 60 seconds.
