Battery Charging
My battery's dead and is in need of re-charging.
I read in the owners manual "If the battery is disconnected, the data for the engine electronics stored in the control unit will be erased"
Being a real novice with this car I'm loathed to screw things up, so choose not to do this. What's the procedure for charging the battery whilst fitted in the car?
Thanks in advance.

If the battery is completely dead it won't matter much if you disconnect it.
You need to charge the battery (duh!). There are ~1 amp (trickle) chargers, 2/10 amp chargers and >10 amp chargers. For a DEAD battery I would use a 2/10 charger, not a trickle charger and I would also disconnect the battery before charging. I would even consider pulling the battery to make sure no "boil over" from the charging occures inside the car. At the very least leave your trunk lid up while charging to let the charge gases escape your trunk.
Also, check the water level BEFORE charging and fill w/ distilled water if it needs any.
As far as the info stored in the DME, as long as you weren't planning on taking the car to get emmisions tested in the next few days it's not an issue, it will "re-learn" after a few drive cycles.

Thanks for the information.
So, if I leave the battery fitted in the car, check the electrolye etc., connect the RED lead to the RED battery terminal, where does the BLACK lead connect to?
Thanks again.

If the battery is being left connected in the car you could connect the black/ground to any metal part of the car, but I would connect it to the neg. term on the battery.

Thanks Bill.
That's what was confusing me. The recharger manual say to connect the negative clamp to the chassis, but if it's OK to connect to the -ve terminal that's the answer.
What would be the problems is I remove the battery, apart from the radio code ?

If your battery is already dead then you have to input the radio code. It makes absolutely no difference if the battery is in the car or out of it. If it makes you feel comfortable, then remove the battery and re charge it out of the car.

Vent tube?
At first glance I can't see anything. The battery installed is the non maintainable type, no way to check any electrolyte levels or anything else for that matter.
Where would I find this vent tube?
Thanks again.

A photo of your battery would be helpful. If it is an acid battery you should be able to check the water level. This is not for a 993, but will provide you info what I mentioned with vent tube. http://www.industryfigure.com/berkel...he/battery.htm I am just concerned if you battery lacks water, and is not vented properly it could a potential battery explosion if you charge a high amps.

I have a dead Optima, my dealer is charging it (my charger indicated it was too low to charge). I was told a Battery Minder or something like it wouldn't keep it charged as Optimas required a charger to charge with 6v min. I don't know if I believe that, anyone have info on maintaining an Optima?

I think there are now some trickle chargers that will maintain a gel better (Battery Tender Plus, is one I think) but most basic maintainers won't.
