The 370Z Weight Reduction Thread

I have relocated batteries and also have used the PC680. Eventually I got back to just replacing OEM bat w/PC680 for weight savings in place. Why? Relocating means heavy gauge wire ('0' - '2') to carry the heavy starter current without voltage drop. Aside from the inconvenience of installing the wire, the potential voltage drop of extra connections, and PITA of stuffing the battery somewhere where it was not designed to be, but the bigger issue is weight.

The heavy cable actually weighs a considerable amount per ft, the new mounting bracket weighs more. Add that up and the battery and you'll find actual total weight saving diminished significantly. Leaving the battery in its original gets you the most static weight lost. The only downside is there is not fore to aft weight change.

The PC680 works good, but tends to discharge quicker over time than stock, and I've found they need replacing about every 2 yrs as they lose charging capacity.
