First trouble with air-cooled Porsche 911 (964 model)|Battery runs out and engine cannot start

The battery in an air-cooled Porsche 911...

We currently have six cars in our house, but we can only fit two in our parking lot.The car is parked in several separate locations, including in the neighborhood and near my husband's work.

Then, the other day, my husband was told that he was going toI'm coming home today in an air-cooled Porsche (964) parked near my office.I said, "I'm sorry," and went to work. It had only been about a week since I parked the car, so I thought there was nothing to worry about, but in the evening I received a text message from my husband.

Air-cooled, battery dead. I'm waiting for my insurance to call for road service.

And.

...Eeeeee!

It's not like the car has been parked for such a long period of time, but how can the battery run out so easily....

From there, about 40 minutes later, "The engine is safely running, so I'm going home!I was contacted by the "Mere Old Man," and shortly after, my husband returned home. I immediately asked him about this matter.

When I tried to get the air-cooled car out of the parking lot where I usually park, the engine wouldn't start, the lights wouldn't come on, nothing would work, and the car wouldn't even move.
It's been almost two years since I bought it, and I've been here without any major problems.Finally came the battery problem.Wa.
I immediately called my insurance road service to hook up the booster and it fired right up. I figured the battery would be fine this time since it had only been sitting there for a week or so.As long as you drive an air-cooled Porsche, you have to expect the battery to run out.Na.
Well, there's even a battery on/off switch.

And. Well, I guess it is something of a challenge to maintain an old car....

Check voltage after starting with booster

Purchase charger and mobile booster

Later, I received a package at home, and when I opened it, I found a battery charger and a jump booster for my mobile. "I ordered this!I say."

With this.If the battery should die, you don't have to call for road service.Yaan. I also bought a charger to keep my car charged when I am not driving. I heard that people who drive super cars need a charger because they don't drive often, and some of them will give you a charger when you buy the car.

and so on.

Jump booster and charger

The jump booster is supposed to provide power to the car and help start the engine as a first aid measure when the battery goes up.

My husband bought this one, which can be used as a regular mobile battery and can also charge a smartphone, in addition to being used as a jump booster.

And he bought a charger from the famous CTEK. (If you want to consider warranty, I recommend you to buy an official import. (If you are considering warranty and so on, I recommend you to buy an authorized import.)

My husband immediately attached a charger to the 964 and began charging it in what is called reconditioning mode. This mode is supposed to revive a discharged battery like this one.

I started charging the battery, and after about 4-5 hours, I checked on it and it was still in the second stage.

The next day, when he looked at it, there were no errors and the battery itself was fully charged, so the damage to the battery itself was okay. And my husband immediately went out for a test run (laughs).

    Hello.

    I'm sorry you had a hard time with the 964's battery.

    I used to keep my 964 in my parents' Yodogawa garage for a long time and only drove it occasionally, so I used to run up the battery often. I was told that it was easy to cause this problem because of the increased standby current due to the sudden increase of electrical equipment in the 964 compared to the 930.

    Also, it may just be my 964, but I had it checked and for some reason the standby current for the A/C switch unit is almost 10 times higher than the 993 unit. I changed the unit to a 993 unit and it was less likely to go up.

    In addition, the battery has not run down since the battery kill switch was installed.
    Also, the domestic (Panasonic) ones hold up better than the original Bosch ones.

    The charger is currently left on in the garage on the property.
    The other day I happened to forget to connect it and it died due to battery over-discharge. (It was 5 years old, so I gave up.)

    Good mobile jump starter!
    I'll buy it...

      I guess there is air-cooling.............................;
      And it's not just a matter of the battery running up, there are many causes and other factors...

      My husband has been saying lately, "There's something wrong.
      He said he would bring it back to the store again soon.

      >The other day I accidentally forgot to connect it and it died due to battery over-discharge.
      I see how that can happen!
      I feel that it takes a lot of knowledge and tools (and money, of course...) to maintain air-cooling these days.

    Hello. I am sure that the battery problem will come unless the car is driven frequently.
    C-TEK is great! I have tried Delco and many other manufacturers, but C-TEK is the best.
    I ended up using C-TEK because the other ones often stopped charging when the voltage dropped too low.

      Thank you!

      >C-TEK I like it!
      I see! So many different types of chargers have different usabilities!
      Study.

      I've yet to run up a battery in my water-cooled Porsche.
      We need to be ready for all kinds of emergencies...!
