Got a new battery last year and went to start my car the other day. It hesitated quite a bit (you can tell the charge is low because the console lights dim and the starter turns slowly).
I actually ran out of juice twice in 2 days and had to get the car bump started. Ever since 4-5 days ago (other than the 2 bump starts) I have had slow, sluggish start ups.
Wondering how to tell if its the battery or the alternator. The only thing I have done recently is installed sidemarkers but that was over 2-3 weeks ago and I doubt I have a bad ground.
Another thing. If I turn my car off (after driving for 20-30 mins) and then turn it on 10 seconds after, it starts up fine. Which is leading me to believe that the alternator is doing its job, and I either have a bad battery or a leeching ground. How can I test for which one it is, if am I correct about the alternator.
You can take the battery to an autozone or whatever to have them try to charge it. They can determine for you if the battery is at the end of its life. Think they should be able to tell within a half hour.
had a similar issue battery and alt tested good with multimeter, it was the starter, had weaker and weaker starts until it wouldn't turn over the motor over i thought it was the battery going out, 5 years old and summer time, push starts car runs normal. if you are getting 12v at the battery in the morning, 13 or so when running, 12 at the starter, then I would have the starter tested
WTB : Complete gsr/type r short block Florida, will take long block if price is right
12.6 after I turn it off. 12.5 with key in ignition and BARELY starts. Very sluggish.
Drove for about an hour today, went to the gas station, left my headlights on, got back in the car, battery was dead. Instrument gauge was dim. Had to push start.
Had car at idle, tested with multimeter, 14.4 Volts, very healthy alternator I believe. I am ruling out leeching since leaving my headlights on after a 1hour drive (charge @ 14.4 volts) for 2 - 4 mins drained my entire battery.... yeah thats a shitty battery.
I forgot to mention, bought the battery 19 months ago, warranty is for 18 months (SOL I guess), and for 4 months this summer the car was driven for maybe 3-7 days, I had something else insured. Heard that lead acid batteries need to be constantly charged or they just corrode and die.
Finally, I put my multimeter on my battery and turned my alarm on/off, it fluctuated from 12.2-12.6 but never going above 12.6. I unplugged MANY fuses and the voltage never went up above 12.6, suggesting that there is no power draw from anything else.
Likely your battery will need to be replaced. It may have suffered sulfonation when sitting for a long period uncharged. Even if you can revive it I doubt that it will be reliable for winter. You can get a load test as noted and be prepared to replace it at the same stop and save a trip/
