Jim GM4DHJ ... used his keyboard to write :
anybody got one of these ? No, but the spec. sounds good. I cannot see a clip on current probe, so no idea how they assess that. |

Cheers, T i m Internal battery resistance is key to starting ability & is a way to measure battery ageing. So you can use that to assess usefulness of out-of-car batteries. Once fitted, cranking voltage is adequate to give some idea of startability, though it's no precise guide. Some oldies give the battery a real hard time during starting, and some modern diesels require high cranking voltage to start at all. NT |

It relies on the built in sensors by the looks of things. The cars computer can probably tell you the state of the battery without it. |

Internal battery resistance is key to starting ability & is a way to measure battery ageing. Sure, but who would use that and when? 'Most people' just start their cars until they don't start, then give it to a garage (or call their breakdown service) and garages are likely to have better tools in any case? Not IME they don't. Three times I told the garage the battery was failing and they "tested" it and said it was OK. Then the car wouldn't start.. Oh its because you don't run it for far enough to charge it was the excuse. The next time it was your dash cam is flattening it. The third time I called the RAC and they came out and did a twenty minute test on the battery, the tester decided the battery was less than 50% of its capacity so they replaced the battery. Told the garage to get a better tester and someone that knew how to use it. |

dennis@home expressed precisely :
It relies on the built in sensors by the looks of things. The cars computer can probably tell you the state of the battery without it. The ECU doesn't store that sort of information, that I am aware of, it might store a failure to start, but that unit only seems to clip onto the battery, so it cannot interrogate the car's ECU's. |

What, using the ODB port? It does say it has an ODB connector. |

dennis@home presented the following explanation :
Well maybe it connects to the OBD port like it implies in the picture. No sign of an OBD plug in the photos. The only setting seems to be for the species of crank current reading you want to be displayed. |

laid this down on his screen : Measure oc battery voltage Easy. Measure battery resistance How do they do that - place a small load on the battery, then measure the voltage drop? Cannot be much of a load, in such a small device. It could be a failt large load, but only for a very short time. SteveW |

dennis@home formulated on Friday :
It does say it has an ODB connector. Not that I could find, I even tried 'Find' on the page and that found no mention. |

Lonely Psychopathic Senile Ozzie Troll Alert!

Speed, the auto-contradicting senile sociopath, blabbered, again: Measure oc battery voltage That device can't do that. Do you get some sort of senile "climax", any time you auto-contradict, senile asshole? -- Kerr-Mudd,John addressing senile Rot: "Auto-contradictor Rod is back! (in the KF)" MID: |
