  • FL-1215 is a 12V 15ah is a specifically designed racing battery for the customer looking for the power of a 12-volt battery that does not have the large amperage draws to warrant a larger battery. This battery is 2nd to none, simply the best 12V-volt for applications on the market, that need the extra punch out of a 12-volt battery for starting a hard to start high cranking compression small displacement race engine. This battery was designed to start the hardest engines with cranking amps like nothing else available in its size.

    The FL-1215 the battery is becoming the choice for many not needing Large capcity but want to have an easier time starting their engines, simply because of its small size and Feather-Lite weight. Do Not be fouled by this batteries small size or Feather-Lite weight, they pack more of a punch with better reliability, for the customer not requiring tons of capacity.

Its small stature brings it in at 3.5” long 2.5” wide 4.5” tall makes it have the smallest footprint of any battery in the same performance category. With 520 cranking amps (15 seconds) this battery has the fastest engine starting power every single time, you would need 2 of every other battery on the market minimum to match that power and surpass our capacity, some companies you may need 3 or 4 of them.
