Our Braille B3121 lightweight AGM battery is our lightest do everything battery yet, weighing in at just under 22 lbs. Using our Advanced AGM racing technology, we have put a lot of power into a very small package.

With 1380 pulse cranking amps this has enough power to start more than any other battery in its weight class. This is the perfect model for those who want to shave half the weight of a standard Group 34 battery and still have enough power to crank over a street car with V8 engine & standard compression.

Used in everything from large Harley Davidsons to Hot Rods, road race cars, Corvettes & Vipers. (Note: while high in cranking amps, make sure battery has enough capacity for the vehicle intended to be used in.  Not designed for big block, high compression motors, those with no alternator, etc. (Where a full-size battery with high capacity is required).

I would not recommend this.
Size: 0.75 Ounce (Pack of 2)
For me it only helped for about 15 minutes at the most. I do NOT want to have to keep spraying all day!

Helps with dry mouth
Scent Name: Berry, Size: 40 Count (Pack of 1)
I purchased this because I’ve noticed as I get older that my mouth produces less saliva. I have been experiencing dry mouth more and more often, especially at night. I started mouth taping and using xylitol melts and I’ve seen a huge improvement in my overall oral health. They are easy to use, taste good and were comfortable overnight. Highly recommend.
