Re: Braille battery's
Braille batterys are AGM=absorbed glass mat. So there is no fluid in the battery, also its a carbon fiber shell an purely asthetic an eye appeal. They also need use on a daily basis, leting them sit for a week at a time is very bad for them.
Well, there is liquid, its just absorbed in a glass mat. But, point being, it isn't some special technology that allows a smaller lighter battery that produces the same amout of cranking amps and the same reserve capacity as a bigger heavier battery. So to get the smaller size and weight you have to give up something, most likely reserve capacity. The fact that they advertise it as "Carbon Fiber" and smaller/lighter without touting some advanced technology that makes it more powerful makes me leary. it isn't smaller or lighter because its made out of carbon fiber, its smaller and lighter because its, well, smaller and thus lighter. A Buell (Harley) motorcycle battery is smaller and lighter (and AGM too) as well, but its no car battery, even if it might work.
All that said to say, if your going for smaller and lighter your giving something up, most likely reserve capacity and some CCA. Thats a LOT of money for a less capable battery thats just lighter.
An alternative option is as mentioned, a Lithium Iron battery. Becoming very common in the motorcycle world and proving to be fairly reliable. You have to keep your eye on it a bit more than a simple lead acid, but not a whole lot. They are comperable in price to this battey too. Going that route might allow you to keep a good CCA rating, and reserve capacity, while still getting a smaller and MUCH lighter battery. If a 1.5lb battery can live and work for years under the seat of a single cylinder air cooled thumper motorcycle, it might be viable for these trucks too.
