The voltage reading is kind of on the low side. Your battery reader rosak kah?

QUOTE(allenultra @ May 15 2019, 10:28 AM) When battery not connected to the vehicle or when engine is off (alternator not charging), its normal to be in that range. Because one plate is supply 2.2v, in series of 6 equals 13.2v. Factoring internal resistance, shouldn't it be around or higher than 12.8v?When engine on, it usually follow the alternator voltage. Dun say the battery tester rosak, later the French guy (DHC from France) not happy   This camel is Q85/D23L that you pasang in mazda? |

QUOTE(allenultra @ May 15 2019, 11:07 AM) I tested all the Varta/Gp/Camel/FIAMM, they are around the same. Tried with other battery testers, same. i see....ini macam ar....And when the engine start and alternator start charging, voltage indicator inside diagnostic tool and battery tester also match. So the battery tester should be good enough. I believe you can pump it up to 13.2v easily when connected to battery charger (if its fully charged), else usually I notice 12.7 +- Yes. Q85 in Mazda 3 Mazda battery current sensor quite a fickle, around 12.5v-12.6v will show warning indicator.... Sorry i didn't buy from you although i asked you for quote. Not too long after receiving your reply, my car cranking much slower than usual. I guess almost dying, to much risk to wait for delivery from your end. So i changed it on my end. Anyway, do you know where to source battery heat shield? This post has been edited by wkc5657: May 15 2019, 11:24 AM |

QUOTE(allenultra @ May 15 2019, 11:23 AM) 12.5-12.6 when engine on? Macam alternator sudah nak kong. [12.5-12.6 when engine off, its fine I mean voltage when engine off. I saw error message, off engine and measure voltage using multimeter, at the around 12.6v.... ]CX5 usually around 13.3v, Mazda2 usually around 13.6/13.7 Then, i damn kiasi, plug in charger overnight. Next day restart car, error message gone. Unless the sensor damn advanced, can also measure CCA on the fly.... This post has been edited by wkc5657: May 15 2019, 11:28 AM |
