Just picked up my Boxster. 2 days later battery died

Hi All,

I write, hoping it would have been better news. Just bought myself my first Boxster. Its a clean '97 model, that had a full PPI check. Received the full bill of health. Now its been two days where the car has not been driven and the battery is completely dead

Interior lights dont work, when I try to start the car, nothing happens, not even the click click click noise of the starter motor. The dash warning lights are all dim, so I'm not able to start my car now! *sigh*

Now my only suspicion is with the side mirror demister. I only say that because even when the key switched off and taken out, the demister light was still on.

I even tried pulling out the fuse, but the light remained on.

Since I have no idea about Porsche's I thought this was normal, but suspicious. But could this be the root cause? The car was sitting off and idle for 2 days like this.

Sigh, any comment would be greatly appreciated, as I've been looking forward to owning one for ages, I just wish the car would start!

As a side note, does anybody know what Optima battery model would fit a Boxster? Or what battery size I should get. I want to start afresh, once the problem is found. I'm located in Australia if that helps

Thanks!

If the battery is over 4 years old replace it.

Have the battery tested and charged.

If the problem continues I would suspect the ignition switch is bad.

Hi Daryl

Good to see more melbourne ppl in here :)

Congrats on the car, as Loren mentioned its quite possibly the ignition draining it, but i know how you feel with the flat battery issue, I managed to get 6 years out of my stock battery, i was quite amazed considering I dont drive the car as much as i useto.

I remembered that once I got it started, I couldnt turn it off for fear of it not starting again (which it wouldn't)

I eventually called marshalls around and they replaced it for $199, doesnt really have any branding on the battery but its got much higher ratings than the stock porsche battery.

General rule of thumb, 4 complete discharges and your batterys as good as dead
