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).

YIX30L, YB30L-B, ETX30L, HD 66010-97

Good, inexpensive work watch
Color: all black watch
Bought as a working watch so I don’t wreck my good watches. It’s been working just fine and holding up well while not taking very good care of it. Keeps accurate time. Glass has stayed clear. Black finish looks good and is holding up well. Seems to hold up with steady pounding. Stop watch buttons are a bit crude and will mess up your time when your hand gets pushed back against it during hard labor. However, I have not babied this watch at all.
