If battery label says 550 CCA but when tested the CCA is 250, is this bad? does this mean the battery is bad? do I need to change ASAP?

sounds like cranking amps. And yes, if it is only half either you are testing it wrong, or it is only cranking half its rated amps which is not good.

thanks for quick response! why is it not good? I thought it has to do with battery be able to start in cold weather. I live in orlando, Fl. Still not good? would you recommend to still change battery?

Cold Cranking Amps. It’s the capacity to produce current when cold. Assuming the battery was tested correctly it’s got less than half its capacity. Why did you have it tested, and how old is it?

I had it tested after I took it to Honda (6 weeks ago) and they told me my battery was bad. I was skeptical so I did not change it. Since then, every now and then (not often) my car will take a bit longer to start. Once it took me 3-4 clicks and then it started. it hasn’t happen since so I want …

I have a battery that (knock on wood) has now lasted over 10 years and shows no sign of going bad, but that is exceptional in my experience. A battery can fail for several reasons, such as diluted fluid from too much outgassing and refilling, from filling with bad water (not distilled) and accumul…

I definitely did not leave the lights on. Lights are bright, AC is fine, etc. Out of the 2 (alternator or being discharged) I’m leaning towards battery being discharged. How can I test for that? Can I fully charge it back to normal and if so, would the CCA number go back up? If it was the altern…

Most parts stores will test both the battery and the charging system for free. Both need to be tested.

The CCA rating and the level of charge have some relation, but they are not one and the same. You can have a fully charged battery but have it’s CCA test to be a very low value if the internal resistance of the battery is high. A half discharged battery can have a very good CCA reading. If the CC…

Just left honda (used the internet there looking up car stuff and this site!) and across the street is autozone. The guy checked it. His meter (or whatever they use) does not give CCA reading. The voltage is good but test says bad battery. I asked him if it was alternator and he said does not se…

If a 550 cca rated battery tests only 250 cca it is drastically undercharged. It may be discharged because the lights were left on. It may be discharged because the alternator isn’t working. It may be discharged because it can no longer hold a charge. Which is the likely problem?
