Porsche battery maintainer


Recommended Posts

Does anyone know the charging specs for the Porsche battery maintainer? Specifically, what are the spec differences between motorcycle and auto modes?

I'm talking about the long, slender maintainer that looks just like a CTEK unit (see pic). I have 2 of these and I can't find the owner's manuals. I also can't seem to find the exact same CTEK model to reference specs. Is the manual online somewhere?

I just picked up a Braille AGM sealed battery for the GT3 and need to know if the Porsche maintainer will be appropriate for use with the Braille battery.

Take a look at the CTEK 3300 battery charger users guide All the CTEK manuals are at http://www.ctek.com/EN-US/Support.aspx

The Porsche battery maintainer is essentially the CTEK 3300 with the Porsche name on it and the cigarette lighter plug adapter as standard. A bit of price difference too. The AGM charging mode is the colder temperature charging setting, not the motorcycle setting. It's 14.7 volts and 3.3 amps. See page 8 of the manual for battery types and settings
