Does not start 2018 Camry LE

Today I learnt a lesson- I turn the ignition switch to start dash lights come on and at the start engine end everything dies.

I checked battery terminals and battery voltage 12.7 volts. When I jump start it starts and battery voltage is 13.4 volts.

I thought it could be the starter and replaced it $209. I tried starting with new starter installed same problem.

Though battery was showing 12.7 volts it didn’t have sufficient Amps to turn starter.

I then bought and replaced new battery $215 Car started and ran. This is just a heads-up if someone has a similar problem please watch out.
