PSA - Don't use a Battery Tender Jr. on your Z

I had to replace my 2009 battery already too. I never used the charger but never checked the fluid level either, and it was low. Tons of heat on track days coupled without maintenance = new battery for me.

I was checking the water level 2yrs ago in the summer & one cell was low & you could see some deterioration occuring but I bought myself some more time by not only using distilled water but by adding a little more acid with it. It has lasted this long but I would be surprised if I got another year out of the factory battery.

Is anyone using the extended storage switch in the fuse block? Nissan expects the car to be stored winters in colder climates and knows that it has a parasitic drain during extended storage and provided an extended storage switch to stop the drain. You just pull out the switch and it cuts power to a few electronic control modules to reduce the current drain. It is actually just a fuse with a big plastic case around it with locking tabs on the side. It's on pages 8-24 & 8-25 of my 2012 owners manual.

You can add the Battery Tender 800 to the list of ones not to use with the 370Z.

I can confirm that the Battery Tender Plus works perfect with the 370Z, been using it for a while with no issues. Just tried the Battery Tender 800 the past few days and it will not charge the battery. Green light comes on like it's topped off but the battery is low.
