Batteries

The plural " batteries " refers to EV batteries

You'd look a bit daft failing that and it wasn't even connected up ,assuming is not enough .

Agreed, there is no reference to any paricular type of battery having different criteria or a limit on how many are testable.

The wording suggests ALL batteries connected are testable

Based on the image, information and IM what would you do if testing that vehicle?

Likewise, or a manual advisory.

What should we do when the manual advisory function is removed!

In your opinion why would an advisory be appropriate in this case vs a minor defect?

Both. I’m interested in why it’s worth a manual advisory but not using the minor defect which is already there. End result is the same, a pass is issued.

N.b. I’m aware of the difference between advisories and minor defects generally.

Fair point on the standard, but it does not specify in the manual to only test batteries that are fitted as standard. As we know, the manual does specify such detail on other areas, so it’s not like there’s no precedent.

Connected, fair point. If it’s not electrically connected it’s simply load. A tester would have to satisfy themselves that it is connected. I accept that there is a quirk that if that battery had the terminals disconnected, it can no longer be a testable item.

I disagree they form any part of the propulsion system. That’s simply not true. A car will propel its self perfectly well without a battery.

Is the mess in the photo any less an issue, if it shorts, than that of a standard fitted battery?

You beat me to that statement

We already have what DVSA consider to be relevant advisories in the None componant advisory section.

Why create an advisory to a minor failure as dwain said
