Car keeps not starting

Any insight to my problem? Every few weeks i go to start my vehicle and it does not turn over. I get it boosted and I’m good for a few weeks. I’ve got to the point where I disabled all the light settings on the instrument cluster. My trusted mechanic has inspected the battery and it turned out to be providing the necessary voltage. I’m at a loss. I have no idea what I should get fixed? Is there something that’s draining by battery?

Ps, Happy thanksgiving

It could be a short, but when your mechanic checks the battery you have just driven the car to him, charging the battery. It could be a loose and or corroded terminal. How old is it? What kind of battery ? Everything should be tested when it won’t start, not after you jump it and drive it, charging it. Do you have a volt meter, various tests can be done with one and if someone can crank it while you operate the meter, to check voltage and voltage drop . I bought my own test equipment so I would know if it’s my battery , you can get good equipment for 50-75$. If it’s a short, you or a mechanic will have to trace it down. But most likely the battery is dying . Most every auto store will test it for free.

How old is the battery? Anything over 5 years is due for replacement. Have you tried charging it properly? Once it's just a tad too low it won't crank at all.

Yes, have the battery charged and tested. If it passes, have the car tested for parasitic draw. Cars these days have many circuits that retain power, but are designed to "go to sleep" when the car is off. If one of them stays up late you'll end up with a dead battery.

Make sure your battery is a Group H7/94R size and has at least 800 cold cranking amps. If it's undersized, you may have difficulty starting it in cooler weather.

Yeah, I have no idea how old the battery is. I purchased the vehicle in 2018. I feel like I'll just end up replacing the battery to prevent further annoyance. Its going in this week for brakes. I'll do it then. Thanks everyone for their input!

Batteries have date codes on them. Also, pretty much any place that sells them can test yours.

Your Location is listed as KW. That can be an abbreviation for Kuwait. If that's where you currently are it's not a "fine" location for a car battery. Extreme heat is not a friend of batteries, general electrical devices or electronics.
