Do I need a new battery ?

Just put on new tires. They checked battery and it was in the 400 range. They said that I needed a new battery. I know that the cold cranking amps is around 750, but it's not cold here, and it starts just fine. Do I need a new battery right now or can I wait a couple of weeks?

What’s the voltage running and not running? Should be around 14.5 and 12.6 respectively.

If it’s starting fine and you’re not in a cold climate, as long as your voltage is ok, I wouldn’t worry about the cca number

A battey that is showing 400 is a toasted battery and just a good way to burn up the alternator and the PCM field circuit. I bet the battery has less than 350 ca at operating temp after heat soak.

In this case it's not so much the cranking amps required by the engine, even if the battery is able to start the engine in warm temperatures, what they tested is the original advertised capacity of the battery versus what it is now actually capable of providing. Assuming the battery is rated for 750 amps as well the testing shows the battery is lunched.

I went ahead and replaced it. When I took it out, I saw that it was the original battery from the factory, so it had a good life.

Thanks for the help guys.

Less-see, if your truck is a 2009, that would mean the battery made it 10 years.
And if your truck is a 2014, well it. Made it 5 years.
So, how long did it last?

The factory installed battery on my 2004 F150 lasted 7 years. I was very surprised, and that made up my mind to always run Motorcraft batteries after that.

my 13 was still holding fine but I changed it in February just cause I knew it would need it.

i had a 2001 f150 new and kept 6 years. It still had original battery too. It sat a whole lot while I was stationed on Mellon.
