Stopped by the dealer to get visual confirmation and hard copy of my 2011 GT3 order specs as it was entered into the system.

Noticed the code ZLB "lightweight battery" showing as a no-cost option with $0 next to it. I just want a normal battery for fear a lightweight one would not be as robust and retain a charge as long when garaged. The dealer claims they've never seen this option before and apparently it's different from the GT3 RS's $1700 lightweight Lithium Ion battery which has option code 191. They tried to remove the option and the system would not let them.

Any idea what this ZLB lightweight battery which I assume is not Lithium Ion is doing in my order? I guess it's standard equipment.

 

Its not the Lit-Ion battery..but it is a (slightly) lighter than the norm 911 battery.

 

I didn't spec light weight lithium battery, but on my window sticker there is $0 option light weight attery option. I opened the battery cover and obviously it is not the Li-ion but a not too big battery.

 

I'd look to see what the difference is. A few pounds doesn't make any difference to the performance and definitely not worth the aggravation of a short-life or weak battery IMO.
