Braille Light Weight Battery & Bracket - weight savings for your M car

For those interested in a light weight Braille battery and mounting plate set-up that will be a very easy bolt-in to your E36/38/39/46/9X chassis, it's here!

Mounting plate is black anodized light weight aluminum, which will fit with either of the 11.5, 15 or 21 lbs Braille light weight battery. Weight savings can be 40+ lbs (depends on the size of battery purchased) when compared to a stock size BMW battery.

The price for the hold down kit is $105.

As for the battery, there are a few choices:

SKU: B3121
Weight: 21 lbs

At 21 pounds the Braille B3121 offers over 1300 pulse cranking amps with 550 cold cranking amps, 31 amp/HR reserve capcity, but still weighs 50% less than its closest competitor. Perfect for Audio Systems, Extreme Motors, and Premium Luxury Vehicles! More details...
Price: $229.99

or

SKU: B2015
Weight: 15 lbs

The Spec B2015 is also perfect for daily street use, even in colder climates. Braille developed the B2015 to excel at racing and to easily power street vehicles equipped with A/C, stereos and power accessories. 1067 pulse cranking amps, 425 cold cranking amps and 20amp/HR reserve capacity. More details...
Price: $199.99


If you choose to use the Carbon Fiber batteries, prices are $70-$80 more per battery. Carbon Fiber battery option will require a lead time of 3-5 business days.

For more information on the Braille Battery, please visit their website:

http://www.braillebattery.com/


We recommend a minimum of B3121(21lb battery) for the E9X 3-series because of the greater number of electronic consumers(DME, MRS, CAS, DSC, ZKE just to name a few).

Order yours here:

Garage List
Do we have stats/info on the stock battery as far as cranking amps and reserve goes?

The Braille 21 has more than enough cranking power to turn over the M3 power plant many times over.

If you like to sit and listen to your radio for hours with the engine off, the Braille 21 may not be up to the task.

Heh, carbon being used for looks in places you can't even see it now.

I can't imagine pulling up to a meet and pulling out my battery to show everyone the carbon on it.

Carbon battery at 11.5, 15 or 21 lbs weighs the same as the regular finish batter at 11.5, 15 or 21 lbs.

It's maily for looks. Carbon just looks cool, but can't really be seen when it's sitting in your trunk.

Dealer may frown on the Braille battery just like other aftermarket mods. Remove it before the dealer visit is a good idea.

Only if the battery is not kept charged up or the vehicle is driven for very short distances and just parked most of the time.
