Could you explain “start-up amps”?

CA and CCA have been used since 1914 as a definition for battery performance.  CA is defined as a measurement of the number of amps a 12V battery can deliver for 30 seconds at 32˚F and not drop below 7.2 volts. CCA is the same test at 0˚F.

These tests were meaningful especially before computerized ignition, fuel injection and gear reduction starters. The cars of yesteryear in need of a tune up could often be a real challenge to get started.  Back then CA and CCA numbers were very meaningful; however, a modern car starts within a few seconds of turning the key.

XS Power batteries when compared to the batteries of yesteryear deliver much more of their power at start-up.  This instant cranking energy we call “start-up amps”. It should be noted that the lower the temperature and the longer you need to crank, the more important CA and CCA test become.  For most performance applications, “start-up” power is more meaningful.

Are all 16 Volt batteries tested alike?

Unfortunately no.  Powermaster is a member of BCI (Battery Council International) and tests all our batteries to BCI specifications.  We test our 16 Volt battery to 16 Volt specifications.  Other suppliers of 16 Volt batteries test to 12 Volt specifications. If XS Power batteries were tested the same as our competitors, our CA numbers would be considerably higher.

Why do XS Power Batteries cost more than Flooded Batteries?

1) XS Power batteries are manufactured using only virgin lead, 99.99% pure compared to most batteries that use 
     recycled lead.  The pure-lead design means better performance.  In other words, MORE POWER!

2) Grids are thinner.  This allows for more grids which means more surface area in a smaller package.  More
     surface area means MORE POWER!

3) AGM (Absorbed Glass Mat) design means longer life, vibration resistant, deep cycle & can be mounted in any
   position (except upside down).

Why do XS Power 12 Volt batteries come with a metal case?

To protect the plastic case. XS Power batteries are under higher pressure than flooded batteries. The metal case will protect the battery from swelling.
