Blue Smart IP65, calcium battery

I am interested in purchasing Victron Blue Smart IP65, which is explained in the manual:
https://www.victronenergy.pl/upload/documents/Folder-A5-Blue-Smart-IP65-Charger-230V_PL_web.pdf

The table recommends 5A for "classic" and 15A for "modern" (while limiting batteries to 50-150 Ah). I have a hybrid car, but a rather old type battery - calcium 45Ah (originally installed at the Toyota factory, 2021).

Does the above limitation preclude my battery? (45 <50, which is given here as a minimum)

I mention that I want to charge without disconnecting the battery from the system.

Usually the battery makers specify charge rates and parameters.

I know the charging parameters. I am asking about the range (50-150 in the manual when mine is 45) and about the stability of the charger voltage, so I do not ask about my battery, but about the charger.

If you know the parameters, why are you asking the question? Charging voltage, current, absorption, float for your battery are all a mystery to us. All we can say about the statement you quote is that it is a guideline. But choice should be based on specifics.

You are not reading the question completely? Why do you answer if you don't want to answer?

Because you don't give us the necessary information.

I found a charger, the manufacturer of which (CTEK) provides the necessary data, so the problem is over.

My post was deleted. This confirms the correctness of the impression that Victron in its offer and even in the manual do not expressly express itself as if it had something to hide.

I unnecessarily rolled out a sad words.
So a sincere apology.

PS. At Ctek, it is also difficult to find out something in detail, so I guess these are that times for us: head in Europe, hands in China - too long a distance for communication to go well.

It's ok @xyzt, these are frustrating times for all.

I'm not really familiar personally with these devices, but what you're reading is just a 'Guide'. I very much doubt your smaller battery precludes anything, but just be aware that a larger unit may exceed recommended charge rates for the battery. That wouldn't worry me, as V would usually limit charge, but it's your choice.

I'm sure Victron would love to have you as a happy customer.
