Stinger SPP1200 Manual

Battery Testing
Testing your SPP1200 to determine its functional condition can
be done in two ways. The first is to test the open circuit voltage
of the battery to determine the state of charge with a voltmeter.
Testing Open Circuit Voltage means testing the battery’s voltage
with nothing connected to the battery (disconnect one terminal).
Consult the chart below to compare your readings:
Having the proper battery or amount of batteries for the system
to be powered is extremely important to the life of the battery.
When planning your power delivery system make sure you have
the right amount of battery power so as to not discharge the bat-
tery too deeply during normal operation. Even though the
Stinger batteries have the best deep cycling ability in the market,
the deeper the battery is cycled the shorter the life expectancy
will be. This is evident in the chart below:

Proper Battery Selection
The second way to test the battery is by using a load tester (usu-
ally available at your Stinger® dealer or most auto service cen-
ters). A load test is performed on batteries that are suspect of
having reduced output capacity. For example a battery’s open
circuit voltage tests good but the battery is unable to support a
load.
Approximate Charging Times

Proper charging is crucial for proper performance of the
SPP1200. We recommend keeping the SPP1200’s voltage
maintained at 12.8 volts (open circuit) by means of a properly
designed regulated charging system. If your battery has been
discharged well below the recommended 12.8 volts we recom-
mend following chart to the right for proper recharging of the
SPP1200. The charging times stated are using an automotive
Current Tapering Charger or otherwise know as a Constant
Voltage Charger. These chargers are microprocessor controlled
and will regulate the charge voltage and current far better than
the run of the mill automotive power charger. Contact Stinger®
for more information on how to obtain one of these superior char-
gers.
Never use an inexpensive constant current or “trickle” charger!
These chargers do not have regulated charging abilities. They
can overcharge the SPP1200 causing severe damage to the bat-
tery. Even a small amount or .5 amp from a trickle charger if left
on after the battery is fully charged will overcharge the battery.
Overcharging will overheat and dry out the electrolyte causing
the battery to fail prematurely. Overcharged batteries are not
covered under warranty.
An undercharged battery not only has a temporary reduction in
capacity, if left in an undercharged state or continually under-
charged, the capacity and life of the battery will be permanently
reduced. The battery warranty does not cover batteries that fail
due to undercharging. For this reason we recommend that you
keep the battery fully charged at all times with a properly
designed charging system that charges at 13.8 volts for float/
standby usage and 14.5-15 volts in cyclic applications.

Removing or destroying the battery’s shipping date code.
Long Time Vehicle Storage
If you are going to store your vehicle for longer than 30 days you will
need to take the following steps to prevent long term damage to the
SPP1200.
1. Disconnect the battery from any and all power draining devices.
2. Do not leave a trickle charger on the battery. This will overcharge
the battery.
3. If you have components that need to stay powered during storage
ie; car alarm system, you may use a battery tender device. They
have a regulated output that will monitor battery voltage closely and
keep the battery at peak voltage. Choose a tender that has the abil-
ity to reduce charge to .05 amps (five hundredths of an amp, not half
an amp).
