Does the NSX drain its battery ?

[mikec]

As with most everyday cars, battery life is not an issue. My old chevy can sit 3 months and start just fine. I've had my RX7 sit over a winter, and start just fine. Then when I got an 88 Porsche 928, I learned that for some reason that no one seemed to know (they blame it on all the power hungry computers the car has that are kept running), the battery would die in 5 to 7 days if the car was not driven. And, It wasn't just my car. It was a common complaint. The P dealer even had a tech bullitan about it. The fix? Install a battery maintainer and plug the car in when not in use. And I did.. for 8 years. It was like I was driving an electric car.

I'm beginning to read some posts that the NSX may be similar. The longest my 01 has gone without being driven is 10 days after which it started fine. But... do these cars suffer from heavy battery drain also? should I be getting a battery maintainer ready? I hope not. One reason I chose the NSX was because it was billed at the "pracitcal" exotic. I'm not complaining, mine you, its a small price to pay for the pleasure this car brings me, but I was hoping to save my extension cord for a real electric vehicle.

Ive let mine go 2-3 weeks without starting it and it was struggling to start due to low battery power.

If you drive the car every few days, that's usually enough to "recharge" the lost power of sitting idle for a few days.

The common rule that Ive followed is: Drive the car, for 30 minutes, always above 3000 rpms (for optimal alternator charging) at least once a week and everything is fine.

Any longer than that, and I plug it into my battery maintainer.

Anycar with an alarm system is going to slowly drain a battery. I believe the alarm system drains more than the computer. You can extend the period between starts by putting in a larger battery (higher amp-hour rating). But it is good practice for all cars to be started semi-frequently and driven a little. Batteries like it, engines like it, etc. Keeps the engine well lubed and makes batteries last longer.

Some good information on what takes how much power when sitting in the garage.

The first time I didn't drive the NSX for a week, it cranked a little too slow for my taste. I put a maintainer on it since.
