Battery Tender for Winter Storage Advice

Battery Tender for Winter Storage Advice
Hello All!
So the evil snow is starting to fall here and it is time to prep for winter storage
The new issue for me to consider this year is the fact that my car is now running a fancy *** alarm system that I am sure will cause me endless headaches if I lose battery power.....
So my question is; can I (or should I) hook up a float charger over winter to keep my battery alive? Will this damage the ECU, or gauges etc that I have installed?
I pretty much know nothing about electronics so wondered who has done this and what should I avoid doing? I was planning to use something like the Battery Tender Plus:
Thanks for all and any advice!

FYI this is for my FD if it matters.

Maybe endless headaches was the wrong phrase.
Winter is long here with ~8 months where the car is parked. I want to avoid the alarm system complaining every two weeks that the battery is low.
If it did not have the alarm system I would just pull the battery out and be done. But I have a lot of $$$ into this build and I need the alarm to help me sleep at night when I am on vacation!
Thanks for the advice though!

A real nice thing with them is that they offer wires-in connectors so that you dont need to use the clamps. You just mount them to your battery cables and use the plug when you need to charge.
This means you can have the connector somewhere easy to reach, not needing to open the hood to charge.

However, due to my alarm I need to leave the battery hooked up to this vehicle. So I am after a charger that is safe to use all winter while the battery is still connected.

CTEK chargers are great and yes, they are OEM providers for Porsche/Ferrari/etc.
I have this one that I use on my 987S. I don't know if a battery tender is 100% necessary for the older cars like FDs, but for the newer ones with all the electronics, you definitely will want something! If I don't drive the 987S often enough, the battery definitely loses voltage.

Thanks for your input!
I definitely need one - my alarm system drains the battery in 14 days to the point where the car just barely cranks over and starts

I'm also here in Alberta and use a CTEK MUS 4.3.... you cannot beat CTEK - absolute best in the industry. You'll be nothing but pleased with it.

So a quick update for anyone looking at this in the future:
As mentioned I purchased a CTEK MUS 4.3. I hooked it up directly to my battery terminal clamps using the supplied cables. Made for a nice clean install as per the picture below.
I have been using the unit for a couple of months now and am very happy with it. It seems to do a great job and all my fancy electronics including the alarm seem to be functioning as per normal.
Thanks to the snap in connector it is super easy to plug in/remove the unit and it does not seem to get hot at all. Therefore I have no concerns leaving it hooked into my car until the spring
if i have any issues in the future, I will let you all know!

What I am implying here is make sure that you don't have some other load/leakage from the battery with the ignition off before you put the car on a trickle charger with the battery connected to the vehicle.
I did not do this and I found corrosion build up after a winter on one of the connectors from the charging harness to the front harness (I forget if it was X11 or X12 connector). I obviously have a drain that I have to find and fix and I am lucky I just got some corrosion- this could lead to an electrical fire.

That doesn't sound right to me, but if you contact the manufacturer of the alarm and they agree that is normal drain then I would proceed as you have planned.

Hey, thanks for sharing - I definitely do not want a fire!
However, this actually is normal drain due to the type of alarm system I have. Plus the car was fully rewired as part of my engine build so I should be all good.
