aftermarket battery charger discovered in car

Recommended Posts

I bought my 2007 C4S as a CPO from a dealer a year and a half ago. My battery died this weekend (had used it for about 2 weeks and didn't think to use my battery tender plus) but when I tried to replace it found this aftermarket battery charger attached to my car's battery. Dealer didn't mention this to me when I bought it at ~16,000 miles (now has ~32,000). Just for fun I tried plugging it in to a wall outlet but the red charging light didn't turn on.

Having this piece of hardware there made unscrewing the secure housing/mount a bit tricky but I swapped the old for a new battery and the car is back to full function. Didn't re-install the charger.

Question: anyone have any experience with this Solar 1.5 amp battery charger? Would it be worth trying to install again or is it junk since the light didn't turn on anyway when I tested it? Notably, the red + cable was attached ot the battery but the black was secured to the vehicle (i.e. grounded), not the - charge.

Shouldn't the dealer have found this and mentioned it to me?

This is a cheaply made charger from Clore Automotive in Kansas. Sold on Amazon, not particularly good, but cheap. I'd trash it an get a Ctek.

I already have the battery tender plus from amazon

http://www.amazon.com/Battery-Tender-021-0128-Plus-Charger/dp/B00068XCQU/ref=sr_1_1?ie=UTF8&qid=1350844571&sr=8-1&keywords=battery+tender+plus

Any advantage of the CTEK over battery tender? One drawback (potentially) of the battery tender is that it requires charging using the alligator clips directly to battery. Does the CTEK get around this?

The Ctek has multiple advantages; first, and perhaps most important, all Ctek units have a desulfation step as part of their charge profiles. Sulfating is one of the principal reasons why a battery dies prematurely, running this step every time the Ctek cycles is critical to lengthening the battery's life. No Battery Tenders ever made have this desulfation step in their systems. And, yes, Ctek does have the correct lighter socket adaptor to utilize Porsche's ability to charge through the lighter. Ctek also has a variety of other adaptors, including ones that permanently attach to the battery if you want to go that way. Ctek also makes Porsche’s branded maintainer, but I would not buy one from them as they are way over priced and exactly the same as Ctek’s 3300 model, which you can buy online much cheaper from Amazon and others.

      2002 Carrera 4S. I did a search and didn't see these exact symptoms simultaneously.
      See attached picture. I was driving at 5k RPM in 3rd when the power of the car was suddenly reduced (by the computer I believe) and the console beeped displaying the following 4 checks: 1. Brake distribution 2. PSM failure 3. ABS failure 4. Battery -- also, as you can see in the pic, the battery voltage meter is maxing out. When I disengage the clutch from the engine the voltage drops some (and the brake/ PSM/ ABS messages go away and are temporarily ok) but is still running significantly higher than what I'm used to seeing. Could this high voltage be damaging to the electronics system? Presumably there's something going on with the voltage regulator. Does the ABS/ PSM turn off automatically for saftey when there are voltage spikes?
      My battery is an Interstate and is ~ 1yr old. This seems to me like the alternator (possibly the voltage regulator). I realize it would be better if I had a Durametric to hook it up to and get the exact error codes off of. That may need to be done to properly diagnose what's going on here.
      Thanks in advance for any help/input.
      Cheers,
      Alex

      (60,000km on the odometer) Now the car is completely dead with no Interior lights anywhere.  Car was sitting there with a charger on timer charging for maybe an hour per day for a month while I was on vacation.  The CD/radio was making a clicking sound prior to and I thought the battery needs a boost to start after a month.  Now nothing!

      Well almost nothing - behind the dash board there is some very weak clicking/sound.

      Thought I ask here first - before towing it to the Porsche dealership. ?

      I just recently put a new battery in my 2000 Porsche Boxster and now my radio is requesting a 4 digit code. It is a cdr 220 radio, Becker 1. Type 4462. And the serial number is y5043037. Please HELP if anyone knows how to remedy this. Thank you!

      The battery of my car has been disconnected for about 2 weeks.  Are there any issues to be expected when I reconnect the battery and start the car again?
       
      Also, on one of the electrodes  I cannot get the specified torque. The 2 lugs on the wire don't stay parallel.  Anything that I can do besides replacing the wire?
       
      Thanks

      I am considering keeping a jump starter portable external battery  in the car.  I am wondering if this battery could be used, when connected to the car electrical system through the cigarette lighter socket, to power the car electrical system to allow me to drive back home in case the alternator fails and the car battery is low.  Vendors claim that the car could even be started using the external battery connected through the cigarette lighter socket.
       
      Is there any risk of damaging any car electrical system components doing this?
       
      Thanks
