Z storage and maintenance during Winter

b15

Everyone has their own opinion on this. For me, I change the oil before storage and take it on a nice long run to get the engine/oil temps up. Then I do a full detail, hook it up to a battery maintainer and put her in the garage under the cover. I will not start it up until we get decent spring weather. Last time my Z ran was the first week of Nov.

Personally I don't think idling the car in the middle of winter a couple times a month is beneficial. Given your battery isn't dead, modern day cars should start right up with no issues after sitting for a few months.

Mine only last 2 weeks. The battery dies so quick.

Thats odd. I still have my oem battery and during the summer there's times where I dont drive it for 2-3weeks and it still starts right up.

Do you have any aftermarket electronics? Maybe your battery is going bad?

Yea I have aftermarket sound system wired up with the capacitor. But because my battery dies very often during the winter time, might as well my battery is going bad.

I finally read the manual ( funny huh?) and it says to disconnect the negative terminal on the battery for storage over 30 days to prevent battery discharge.

Its been so shity here this winter . Anyways, I change the oil right after putting her back on the road , if it helps or not, next year i will use a battery trickle. Recently it didnt start well when very cold so I ran it 35 min in nuetral( any difference on that) and moved her out back and forth to roll the tires. Next yr, maybe differnt.

Disconnecting the battery for storage is an unnecessary inconvenience, window reprogramming, radio etc, if you just hook it up to a $40 Battery Tender (maintainer, float charger...whatever, but not a trickle charger).

They recommend disconnecting in order to prevent parasitic drain. If it's on a float charger, that doesn't matter.
