This gets fitted on Saturday, I can always revert to the standard wheel if I hate it:



Onto the main subject on my mind today - battery life.

I parked the car, alarm on, then went to Sicily for two weeks.

Came back, car is totally dead - clock set to zero and the radio needing the code entered.

I tried to jump it from the Volvo (also parked for the same length of time and started on the first spin), but the Porsche battery was simply too flat, so the 911 is now standing immobile whilst I wait for a CTEK charger to arrive.

Is this (2 weeks to total flatness) normal? Or is my battery FUBAR?
Which wheel is that?

Battery dead unless you find something is draining it.

If its an OPC supplied MOLL battery they are the worst batteries ever fitted to any car.

In the 8+ yrs I've had mine, 2 weeks is about normal.

I bought a C Tek a couple of years ago & it would sit in the garage on charge, currently using my garage for other things so the C Tek only gets used occasionally if the weather is dry frown

If my car stands for a couple of weeks it's slow to turn over, battery usually lasts around 4 weeks before it won't start.

Nice wheel BTW, there's one on my want list for my car

Bosch S5 is normally recommended I believe.

My 996 goes into some form of shutdown after a couple of weeks where button on key does not open doors.

That's some sort of hibernation though, not related to the battery going flat, in fact it saves the battery.

Mine has a smaller than standard battery, 095 I think rather than 110? Mainly as it's lighter & there is no massive downside, the larger batteries should last a little longer than mine.

After 5 days no use and to prevent power drain it will hibernate. You will need to use manual key unlock, then register key job in the ignition within 10secs of opening the door to prevent alarm going off.

If flat battery, then interlocks will prevent lid releases - refer to your owners handbook.

mine did this when left for a long period .... ended up getting a little solar charger that you stick in the screen (connects via the OBD port).

It still hibernates, but at least there will be juice.

Started looking for one of these but got quickly overwhelmed by the array of options. Which one do you have?

Battery - Euro Car Parts have a Bosch S5 100 that I could pick up tomorrow, is that a good choice or would another model be better?

Bosch S5 - Pretty certain it was where I got mine - remember to try discount code on checkout PAYDAY35. Otherwise, wait until weekend for other codes.

Carparts4less cheaper by £20 for that battery. Think they are part of the same company as Eurocarparts too. Some great prices at cp4less, just ordered rear discs and pads for my 996- at £108 for the lot , bargain !! biggrin

There are a significant number of Bosch S5 variants- the 100 is the one I have reserved for collection tomorrow, is there a different one that people would recommend?

You want the silver top Bosch battery not blue top.

Silver comes with 5 year warranty blue 3 years.
