This CTEK?

This model will work right? If not can you point me to the right one on Amazon?

I have the CTEK 4.3. Works great for my three Porsches. You might want the optional cig/12v plug so you can charge through your outlet.

Yes, the one you chose will work. Without going through the spec sheet it looks like the only difference between this one and the 4.3 might be the information display and the 3300 might be a lower power unit. ( 3.3 amps vs 4.3 amps?)

I have the CTEK MXS 5.0 with the cable attached directly to the battery (car closed and locked).

It needs to have snowflake mode and 14.7 V charging capability for the AGM battery. Looks like the 3300 model has 14.7V and 3.3 A on snowflake mode. The 4.3 model has 14.7V/4.3A, but also has a pulse charging setting for long storage. That's why I went with that one. The 5.0 is even better but figured I would get the cheapest one that worked for sure.

Yes with the adapter 56-263. Clips right in and door closes without issue. Should work in passenger footwel or smoking package plug.

It does not have to be a ctek, any battery maintainer will work - you don't have to spend $70 to maintain your battery.

Can you recommend a model that is sold by amazon?

I have been using this for years on my Porsches - no issues whatsoever.

Also, hear that Noco is good, but do not have experience with it as a maintainer, but I do have a Noco Genius battery pack, which is great.

I have this exact model , hook it directly to the battery and it works fine. I don't know what the snowflake symbol means, I just put it on the car symbol and it seems to work .
