Trickle Charging a C7 battery
Having owned C5 and C6 convertibles which have been stored for the
winter, I have become accustomed to using a trickle charger directly connected to the battery for many years. The rest of the car has been disconnected and only the trickle charger has been connected to the battery. The new C7 battery is no longer under the hood. It is in the trunk, and not as easily to disconnect and trickle charge. My question: Can I trickle charge via the cigarette lighter socket or another auxiliary power 12 V socket which the car also provides? Or do I have to get into the trunk, remove the trunk lining, and then connect directly across the battery as I have previously done for the last 15 years on my C5 and C6? Any advice would be appreciated. Thanks. |

Turn off the car, open door, remove ignition key. Plug something into the accessory socket. If it works, you can trickle charge via that outlet. If it's dead, so are you hopes of trickle charging in that manner. Most of the trickle chargers available these days (battery maintainers) have both battery clips as well as a plug and socket. Why not just connect a lightweight cable and plug to the battery? Summer months, leave the plug capped and cable stowed next to battery. Connect it to the maintainer cable in the winter. That's how I do it with my C5 and formerly did it with my C4. |

I was concerned that the 12 volt sockets had diodes or some other method to prevent a current source to drive them rather than use them as a source of current. I also worried that the modern technique of disabling a power port when the key is off may, as you have indicated, disable the port after the engine is shut down. I like the idea of a direct connection to the battery, and indeed did that very same thing on both my C5 and C6. In both cases, however, I did not make such an attachment when the car was in the warranty period. I merely opened the hood and used the alligator clips / connectors directly to the battery. With the C7 battery concealed under trunk carpeting, this does not appear to be an option, although I may actually find it to be easier than I think. I have not pulled up the trunk carpet to really research this carefully, and felt my "best" option for the warranty period would be to use one of the 12 volt sockets. The C7 actually has a 12V port in the trunk, and perhaps this one will stay alive after the engine is off. I intend to test this as soon as the trickle charger and accessory cigarette plug cord arrive. Thank you very much again. > > > |

Similar to the C6 and C5, in having a fob used as a remote control as well as a key. The only difference in the C7 is that the key is hidden inside the fob, and can be extracted by a simple motion. In the older C6 and C5, the key was a separate item and was not designed to be stowed inside the fob.. |

Though I have had the fob battery die on me once - now I keep a spare in the box. I haven't seen a C7 up close, but it sounds like they put the battery in the C7 in the same location as on my Z06 - right rear? Difference being that mine is in what was/is a storage compartment with a lid in an standards C6, and the hinged lid is still there and provides easy access to the battery. So how are you supposed to change the thing? But I should think that the ability to charge it would be similar to being able to do the same on my Z06 - check with a tech. -- - Rufus |

What a deal! With that sale price, I wonder how much better it would be than a Schauer or Black & Decker for about $80 to $90 less? Suppose it would be just the thing if you were going to show your car and wanted to put the battery maintainer on the roof so everyone knows you're "keeping it real." Would you buy windshield washer fluid in a jug with a C-7 logo on it for $12.00? |

The re-branded CTEK charger is an excellent charger, and similar to the one I am using. I can do without the C& logo and extra price premium. If there is one thing a C7 does not need, it is any additional attempts to grab attention with C7 logos. This C7 is a magnet for drawing anybody and everybody's attention, For whatever it is worth, BTW, the CTEK charging through the trunk auxiliary port is working out great. Very nice way to keep it charged. The only very minor problem is to be sure the trunk lid is down far enough to prevent the interior trunk lamps from illuminating / drawing power, while at the same time not applying a lot of crushing force on the CTEK cable which is coming out of the trunk to the charger. > > > |
