I've seen quite a few threads about using the Braille line of batteries for weight reduction but not necessarily anything about longevity. For anybody who has one, how long have you had it in the Cayman and any negative experiences so far. I'm assuming daily drivers also and not just for track use. Seems like a cheap way of weight reduction.

It's not in a Cayman, but a friend of mine has a Braille and he likes it a lot. It has enough juice to turn over the engine after not driving for two weeks. He also powers up his stereo setup at different car shows and has had no deep-cycling problems. Besides the weight savings, the Braille at $200 looks nice with the carbon fiber case (his is exposed in the engine bay), but it is supposed to be a rebranded Deka that costs a third less.

I had one on a Lotus. It was fine until a dealer's service dept let it go flat. It was never the same after that and I wound up putting the OEM battery back in.
