1) Reserve Capacity: 80Ah
The Reserve Capacity is a time measurement that explains
how long a fully-charged battery can deliver a 25 amps current
in an 80°F- environment before the battery is discharged and
drops to 10.5 volts.
2) Voltage: 12V
When fully charged, automotive batteries should measure
at 12.6 volts. However, this measurement should be from 13.7

How to Identify What Type of Battery You Have?
Let's take the following picture as an example:

1) Before connecting the clamps to the terminals, please use
sandpaper to polish off the corrosion on the battery terminals.
With this, you can avoid inaccurate test values.
2) Attach the red clamp to the positive (+) terminal, and connect
the black clamp to the negative (-).
• ALWAYS KEEP THE RED & BLACK CLAMPS FROM
TOUCHING.
• ALWAYS DISCONNECT THE NEGATIVE CABLE FROM THE
BATTERY FIRST AND RECONNECT IT LAST.
3) Once the clamps are properly connected, the battery tester
will power on automatically and be ready to conduct tests.
Connect the Clamps to the Battery Terminals (See
Figure 3.3.1)

to 14.7 volts when the engine is running. If the battery tester
reads less than this standard, it means that the battery's
resting voltage is weak. In this case, typically, the battery needs
to be charged or replaced.
3) CCA: 650A (SAE)
The CCA rating refers to how many amps a 12-volt battery
can deliver at 0°F in 30 seconds while maintaining at least a
7.2V voltage. This means that the higher the CCA rating is, the
easier the engine can be cranked in cold temperatures.
