Took the cover off, clicked the remote-nothing. Oh #%it, battery too low. Figured out how to open the door with the emergency key but needed an external battery to power up the frunk so I took a long-time member's suggestion and bought this and this The car was being started every 2 weeks while in a garage that doesn't have electricity to it yet (soon), thought I could get away with it and failed.

Do you store your fob near the car? That could be a drain.

Just starting the car once every two weeks actually drains the battery. You have to drive it to recharge. How long do you leave it in storage? When I parked mine for 2.5 months, I disconnected the battery. Just make sure you leave the frunk open.

Starting the car and not driving it is one of the worst things you can do to a car.

Why is this?

Mike818

off the top of my head:

Engine tolerances are set for a warm engine. When cold there is increased engine wear because of this. A cold engine requires more fuel to start and idle, some of this extra fuel is unburned and contaminates the engine oil. Contaminated oil leads to the break down of engine seals. This fuel contamination is burned off as the car is driven and reaches operating temperature.

I wish I would've seen this tip beforehand, oh well.

At least your glass wasn't cracked again!!

@Wilder That's exactly what I do with my M2 CS which has been off the road since October and unlikely to get out of bed until April / May!
You need to drive the car as you say to keep the battery charged. Took the T for a 50+ mile buzz yesterday and have a long trip planned for the weekend following the oil change. Have the Porsche branded Ctek for time the car is left unused like over a week. Love your 997 GT3 RS what a looker. Congratulations.
Best,

FWIW - 991.1. As tempted as I am on many occasions, I never start the car unless I am going to go long enough to get it to operating temp; oil, not engine temp. Have to take the scenic tour home sometimes, but that’s a nice problem. 75K miles with no issues, squeaks, rattles or leaks.
Living in the south, car is driven every weekend, so at least so far, no need for a charger. Still on the original battery.

Sorry to intrude on the 992 forum.

Excessive wear on most components and small amounts of water being left in the engine.

I agree with never starting the car unless I'm taking at least a 20 minute drive for all the reasons stated above. (I'm not sure I saw bore scoring mentioned above. That's another side effect of idling a cold engine. Extra fuel enters cylinders and washes oil off the walls which allows piston rings to score the walls. The catalytic converters and possibly the turbos won't like idling either. They will never properly, evenly, reach operating temperature at idle.)

If you have no electricity in your garage, you can try a solar powered trickle charger. Otherwise, remove the battery and bring it inside to charge during an extended parking situation.

Idling is the killer of collectible cars.

Scott P

When I start the car I let the cold start rpm's to drop; let it idle a minute, then I would bring the revs up as if I was driving it and down again over about 15 minutes. I did what I could to mimic driving the car never letting it just idle. Oh well, lots of opinions to consider.

Disconnecting the positive alone will save battery charge for months. No need to remove and put on a charger.
