Lightweight Batteries

[longislandwrx]

The group 35 battery that Subaru runs weighs about 38lbs. Personally I plan on running a lightweight battery, lb for dollar it seems like its a smart way to save weight especially since most of the donors I've seen will be requiring a new battery anyway.

In the past I have used a Braille b2015 at just about 15 lbs. for about $175, you are instantly saving 23 lbs. I've had no problem starting the car above 50 degrees and I imagine it would work well in colder areas with a battery warmer/tender. Since this is a summer car, I'm not too concerned.

it will also give you the option of mounting the battery back in the engine compartment and shorten up the heavier power cables.


The Odyssey PC 680 is very similar to the Braille, is a little cheaper @$120... I have not used it though

I've also heard of people running the PC545 on BRZs/FRS but no reason you couldn't run it on a WRX

That one weighs 11.7lbs

Braille also has a new lithium version at 6lbs but for $1500 that's ridiculous.

The Shorai LI batteries are up and coming too but again, I have no experience with them.

Anyone else want to post their lightweight battery of choice?
