I’m completely satisfied with the device despite the small drawback mentioned above.
I have already used it on various types of batteries. A good and useful product.
Resistance values fluctuate; you need to wait a moment for them to stabilize a bit. This is due to imperfect contact on the cable clamps. I’ve seen that probe tips are better.
despite the metal construction, it feels quite flimsy; compared to another one we have from a different company, this one seems like it will last one season
