SPL Series Batteries are available at your Authorized U.S. Amps Dealer, or they can be ordered
factory-direct using the form at the back of this manual, or from our internet web site,
www.usamps.com. Additional battery information is also posted, with an email address for
technical questions.
As mentioned before, most batteries are built for the relatively light chore of starting the engine.
Unless you have the room and ambition to install an upgraded high-powered alternator, your system
current requirements may exceed the charging capability of your car’s electrical system. When this
happens, you have to rely on the vehicle battery(s) to make up the difference.
Another factor to consider is voltage. Although the electrical system is considered to be “12 volt”, the
battery, when healthy, actually “rests”at 12.6 volts. The average alternator “puts out”
when
the engine is on, because it is necessary to “feed” a battery higher voltage in order for it to charge.
All amplifiers operate more efficiently at 14.4 volts, and many, including U.S. Amps, put out more
power at the higher voltage.
U.S. Amps builds two
products, one to recharge the batteries, and one to
increase the system voltage. Both units install and look like amplifiers.
The 12V30 is a 7” long
that plugs into 110V AC wall current and delivers up to 25
amps of DC current at 14.4 volts. The 12V30 is
, meaning that it will charge a
battery until it is full, then maintain a “float” of 14.4 volts.
Floating your batteries at 14.4 volts when they are not in use is the best way to extend battery life.
The concept of the 12V30 is to “plug in” your vehicle when it’s not being driven. The 12V30 will
“slow charge” the batteries and keep them in optimum condition.
It often takes a depleted lead-acid battery over
to recharge, sometimes longer. When is
the last time you drove your car for 8 hours without the radio on? The 12V30 will do the job while
you sleep or work.

THE OPTIMIZER is a DC to DC
, it stabilizes and regulates the vehicle voltage to 14.4 Volts at
100 amps or 16 Volts at 90 amps. THE OPTIMIZER accepts a wide range of input, from 8 to 16 volts
DC. An external voltage monitoring terminal is included to allow THE OPTIMIZER to compensate it's
output voltage for wire loss. Multiple OPTIMIZER units can be used
for any current demand.
If the maximum current output of THE OPTIMIZER is exceeded, it will gradually reduce output to slightly
less than the input battery voltage, preventing a total interruption of power. If left inactive, (turned off)
or if the input voltage exceeds 16 volts, THE OPTIMIZER will "bypass" allowing current to "flow through"
without appreciable loss. In addition, like all
, THE OPTIMIZER is protected against thermal
damage by a solid-state 10.000 cycle thermostat. Additional information about the 12V30 and THE
OPTIMIZER can be found on the U.S. Amps Internet web page:
