I finally got around to installing my Braille 21lb battery that I've had sitting on the shelf for the past year. I chose the Braille 21lb battery because it is robust enough for everyday use and keeps it's charge for a couple of weeks with the car not in use. The Braille 21 is sealed, uses glass mat technology, and thus there is no change of spills. It provides 1380 pulse cranking amps which is far better than the Oddysey batteries, the other popular choice. The challenge with the lightweight batteries lies with the fact that it's not always easy attaching them. I ended up with a simple solution of removing the OEM battery tray, drilling two holes in the base, and pushing two T nuts through the tray from the bottom. I secured the T nuts with some JB weld. The Braille battery is then secured via a cross bar and some 8" bolts I bought at ACE hardware. The cross bar can be made from various material like plastic or aluminum. I used one made from Delrin. The 8" bolt will need to be shortened about 1/4" which is easy to do with a hack saw. This is also a perfect time to clean up the OEM battery tray and spray it black for a new look.

Once the battery tray is modified, it can be bolted back in the car and the battery then bolted to the tray. The factory cables have just enough length to connect to the Braille without any modifications. The battery swap removed 25lbs from the car for under $200. Great bang for the buck....
