The instructions also state:

5. The desulphator should be used in conjunction with a simple trickle
battery charger. We would caution against using the desulphator in
conjunction with more modern intelligent chargers...

And.. recommendations to use a choke in series with (other) inverter type
chargers.

So it seems, the only types of chargers which are considered immune to
damage when used while desulfator pulsers are conected to a battery, are
transformer-rectifier types.

I'd done a considerable amount of reading about desulfator pulsers a few
years ago and found no mention that only the use of basic/dumb chargers as
being the recommended equipment.. although it seemed risky to have high
energy pulses applied to sophisticated chargers' output leads.

The desulphator comes from Courtiestown:

Nice kit. Unless I'm reading the manual incorrectly, it suggests that
it is possible to run a battery charger and this desulfater in
parallel, at the same time.
DO NOT CONNECT THE DESULPHATOR TO THE BATTERY CHARGER
- CONNECT IT TO THE BATTERY & THEN CONNECT THE CHARGER.
MAKE SURE THE BATTERY CHARGER IS UNPLUGGED FROM THE
MAINS SUPPLY BEFORE CONNECTING/ DISCONNECTING.

In my never humble opinion, this is a bad idea, and asking for a
failure. I don't want to think about what high voltage pulses can do
to the attached electronics should the battery discharge and go to
high internal resistance.

The problem that is that the CTEK only stays in desulphation
mode for about 5 seconds.

If repeated at regular intervals, that's allegedly the desireable mode
of operation. Short bursts to break off the lead sulfate
encrustations, and long periods in between bursts for normal
operation.
