Over my many years I have seen car batteries last as little as 1 month to as long as almost 10 years before shorting out. OEM batteries are usually good for at best 2-3 years before they need to be replaced. Of course this is in Houston so what we get for battery life here will be different than in other parts of the country.
@MustangMike2021 A vehicle alternator should be capable of bringing a battery back up to full charge within 8-10 miles after being started. If the battery under charged when the engine started then this can increase the distance/time it takes to reach full charge. Disconnected the battery should read between 12.4-12.8v anything below that could indicate a faulty alternator, shorted cell in the battery, or electronic components in the truck that are putting an increased drain when the truck is shut off. If the battery and alternator check out then they will need to connect a scan tool to it and monitor battery voltage and amperage draw with the system off to check for anything unusual.
