While agreeing with that ^^^ you can get an idea of the batteries condition with a no load standing voltage check.

Also, see what the voltage drops to when turning the engine over.
Saying all that, a new battery is a good place to start. ____________________ Triumph Trophy Launch Edition |

The test we used for big diesel starting batteries was to meter the battery whilst cranking. Works for other stuff, as you'll know.
The issue with this test is being able/knowing how to cut fuel or sparks to prevent the beast starting before you can read the effin meter. 🤣
Also....
If you can get to the electrolyte in each cell, one meter probe on a post then dip the other probe into the electrolyte.
It should read 2volts on a charged battery. (12v battery made up of 6 x 2v cells in series.)
Dip each cell like this and if they're are any that are significantly lower than an average then the battery is phuqued. Probably shorted between cells.
Wash the probes in water to remove the acid.
The test works on flatted batteries but the lower voltages do not show any differences as clearly. Fully charged will shout out a bad cell/s.
The AGM type batteries are excluded from this test. ____________________ Disclaimer: The comments above may be predicted text and not necessarily the opinion of MCN. |
