Here's the actual install It makes it so easy when you have this It doesn't explain it anywhere else but here.

Will this charge the hybrid battery on a nc1 using the factory connecter?

I believe the NC1 hybrid system voltage is around 400 v so that would preclude charging with the Ctek.

The only way I know of to recharge the traction battery in NC1 is to run car in sport+ or track....the Ctek is only for the 12 v bat..but if that goes weak all hell breaks loose with the comp modules..

Indeed! The hybrid batteries are not lead acid batteries and require different charging strategies (and voltages) than conventional lead acid batteries. If the car does not have an explicit charging port for the hybrid drive batteries like a plug in hybrid vehicle (or EV) does, then you pretty much need to leave charging of the hybrid battery to the on-board systems.

So, your comment has me curious. Modern lead acid batteries have this nasty habit of working just fine and then dropping dead from a massive MI as they approach their end of life. This has happened at least twice on my 2000 at 7 - 8 year intervals. Recovery is simple. Install a new battery and you are good to go. Is recovery on the NC1 more complicated? Does the NC1 have a battery condition monitor or do you just pre-emptively replace the battery at 5 years (or what-ever) when you are having an oil change and they can put the car on a battery back up system while they R&R the battery?

I have a Audi A4 mild hybrid. I have not experienced any other car where things can go so wanky when the 12 volt system voltages are less than perfect. Forget a block heater. Starting in October and ending in April the car gets plugged into a C Tek every night to make sure that 12 v battery stays happy.

Since some of the early cars are already at 7 y/o would be interested to hear if folks have had to replace the 12v.And if not , how many miles/year and do they have a tender..
