I have a 2005 trailblazer-6 years old with the original battery. Everything seems to be working fine electrically. The voltmeter it the dash reads 12v with the key turned on and alittle over 14v with the engine running. Will voltage gradually decrease or will I get in the truck one day and not be able to start it. It has 90000 miles on it, I never driven a vehicle this long before so I never had to worry about this. Thanks in advance for any input.

Hi scrapper. thanks alot for your reply. So I should still get a new battery even though the voltmeter says it is spitting out the voltage? Sounds like it could die fast just like that. thanks again
