20 A is higher than 5 or 10 and pretty close to the minimum of 25 (or suggested one).
The problem is that the clicking is present in some models and that is worrysome. I will not leave that charger in there and have that grinding and clicking noise non stop as I don’t believe is ok; ai contraire.

(In regards with your CTEK CS FREE, is intended for Lead acid /Lithium-ion so not sure how that works on the trunk AGM battery).

Either way, 20 A still seems aggressive for the battery charging requirements. The 5 max 10 are suggested for the battery as they are more lenient.
Probably if you use the regular 5 or 10 Noco, you will experience the same problem?

As mentioned before only my M340 does that.

So the problem is still pending…
