Boxster Battery

[lotusrichard]

Hi,

I've got a 2001 Boxster S which I've been using regularly but mainly only for short journeys. I think this and constant use of heating and stereo etc has taken it's toll on the battery because it sounds down on power when I start it now, so I need to charge it.

The manual states that you should remove the power cables from the battery before charging it.......is this really neccessary or is it likely to damage something on this type of car.

All the other cars I've had I have left the power cables on with no problems. On one ocassion I removed the power cables, when the battery was reconnected the ECU seemed to take about 24 hours to reset itself properly, making the car run (idle) differently.

I'm worried that on this car other things would be affected by temperary power loss eg alarm.

Any advice would appreciated.

Thanks very much.....May go for a new battery but in the mean time I need to try and charge this one first.

Do you reccomend I remove the power cables off the battery during charging or is this not neccessary?

Will there be any problems if I do or dont?

Nice one guys!!

Porscheuro - will anything else on my 2001 Boxster S be affected by removing the battery. I'm a little bit worried that things will reset and cause me problems when I put the new battery on.

Also I measured the voltage on my battery before starting the engine, it read 12.1 volts and 14.25 volts when the engine was started.

My friends Nissan 200SX read 12.8 volts before starting the engine and 14.3 volts with the engine started

Is 12.1 volts low or is voltage not really relevent with a knackered battery?

Cheers
