been using the CTEK on the NSX for 17 years, and the GT for 14 years, the best!!!I use this one

I had problems with batteries not exceeding 2-3 years with the Ctek. But perhaps not its fault. I switched to Noco. Will see if it is better.
I agree. The NSX has about a 500 mA drain just sitting there. Disconnecting the batt negative is probably the easiest way, but for those of us who drive their cars in the winter (Colorado is almost always sunny and dry, but cold), the maintainer is easier. Just unplug it and go. For those weeks like this one where we had a foot of snow and the car has to sit in the garage, the maintainer keeps it fresh.In the winter months I use a Ctek MUS Polar on my Audi A4. The NSX is a plonker when it comes to parasitic loads compared to the Audi which has things like electric after run coolant pumps. If you live in a cold climate, be sure to check out the temperature operating limits . The NOCO, Battery Tender and some of the others that I checked out did not guarantee operation below -20C . The MUS Polar was the only maintainer that I could find with guaranteed cold weather operation (down to -30C).
I have never used a maintainer on my NSX when it goes into storage for the winter. I just make sure the battery is charged and disconnect the battery. That has worked just fine for 12 years with both the conventional flooded cell battery which was on the car when I got it and the AGM battery that is now on the car. AGM batteries in particular are excellent at being able to be put into storage and retain their charge. If you are putting the car into storage and don't plan to use it until it comes out of storage next spring, don't bother with a maintainer, just disconnect the battery negative terminal. If this is a case of very infrequent use on nice days then a maintainer would be a good idea.
I think you slipped the decimal place . The NSX seems to run at about 50 - 70 mA. I think most of the variability comes from the measuring device. Some multimeters use fairly high resistance measuring shunts on the low current measurement settings and that resistance can be high enough to reduce the voltage which drops the amount of current being measured from the true value.I agree.

So many choices with these. I wanted the basic to keep my battery charge while not in used
Thanks for all the help this is the one that I bought.

Probably. I only know because I put a multimeter on the car when it was shut off during my re-wiring and alarm work on my 91. That was over 10 years ago lol. It may have been that the alarm itself was drawing the 500 mA...or I read the scale wrong!I think you slipped the decimal place . The NSX seems to run at about 50 - 70 mA.
