Maintaining Your Battery
The following information regarding battery care is furnished to assist you in
the use and maintenance of rechargeable batteries. Battery life is dependent
on the user’s preventative maintenance procedures. Establish regular routines
for all of your batteries regardless of their usage.
Charging a battery is very important. Your Black Cat II Radar Recorder
depends on a fully charged battery to operate efficiently and to produce reli-
able and correct data. Batteries should not be allowed to sit in a discharged
state for any length of time. Once the battery discharges below 11.0 volts,
damage to the cells has already begun. Symptoms of a damaged battery are:
1. The battery will not charge to its full capacity of 13.4 volts or higher.
2. The battery will only hold a charge for a short time under load
conditions.
3. The battery will discharge faster than normal during storage under
no load.
With this in mind, recharge the battery to its highest potential (normally
from 13.4 volts and up) once it has fallen between 11.2 and 11.5 volts. The
battery can be charged using the NOCO Genius 2 Battery Charger that
came with the unit.
Battery Charging
Monitor your battery voltage
by checking the

screen of the STARnext
software. We recommend that
the battery be recharged to its
highest charge level (usually
13.2 volts and above) once it
discharges to between 11.2 &
11.5 volts. A good battery may charge as high as 13.6 volts or better. A
defective battery may not charge any higher than 13.0 volts after a reason-
able charge time. Charge time will vary with the level of the battery voltage.
Usually, a battery of 11.2 volts can be charged to its highest potential in
12 hours or less.
