hey guys looks like mine starting to have issues with battery or no start. yesterday I notice I started the vehicle and left to go to a family house. stoped at a place on the way. had the vehicle off for not more than 2 to 3 mins. decided I go fill up so I cranked it and it seemed it would not start.
died. the second try it started up but barely. I let it sit idling cause I did not want to be stuck. I hope its something to do with battery or alternator not the dam key safety stuff cause soon to be out of warranty.

what can I do to verify a battery?


edit. also if I replace my battery can I go a bit higher like 50 or 100 cold cranks? does it matter? damage anything?

 

Make sure the battery connections are clean and tight. Using a voltmeter ($15 at Walmart/kmart) check the voltage at the battery posts engine off. Should see a minimum of 12.1 volts dc. The best battery test? A load test free at many auto parts stores. A basic alternator check? Start the engine and measure the voltage at the battery again. Should see 13.5 volts dc minimum.

The more CCA the better. Won't hurt anything.

 

I had 12.6vdc off and car running was like 14.6vdc. I think looks good to me. not sure why It acted strange like that. was not like car was parked for more than a day without being driven. although was cold out that night.
I have a fluke 87v

 

Good numbers. Was the red security light flashing?

 

not that I could recall. happened quick. I kinda was paying attention to the start so I backed off the key. should just cranked it and left it but heard the low voltage start that usual when low battery. happened many times in my work vehicle . so I just backed it off. I think I might of turned off the radio, heat and anything before the next start which fired up right away.


strange.
