3.3.1 Maximizing Battery Service Life
The VR100 is powered by a rechargeable lead-acid gel battery. It is normal for the performance of all
rechargeable batteries to diminish gradually over time and with use, but with proper care the VR100
battery should provide a useful service life of several years.
The conditions that cause the most severe degradation of a battery are over-discharging it, and extreme
temperatures (whether operating or not). To protect against these, the VR100 will automatically shut itself
off if the battery is run down, and it manages its internal temperature by shutting down first the battery
charger then the entire receiver if necessary to keep the temperature below an acceptable limit.
To maximize the service life of your VR100 battery, follow these recommendations as much as possible:
Keep the battery fully charged and avoid completely discharging it. When you see the Low Battery
warning indicated on the LEDs, connect the charger. After each time you use the VR100, recharge
the battery even if it is not fully depleted. A series of partial discharges is gentler on the battery
than a deep discharge.
If the VR100 shuts itself down due to a fully discharged battery, do not turn it back on until you
have connected the charger.
Store, charge, and operate the VR100 between 15 C and 25 C if possible. Storing the VR100 long
term at 35 C will actually reduce the battery’s service life by a factor of about ½.
Store the VR100 under clean, dry, non-condensing conditions.
3.3.2 Long-Term Storage
The VR100’s battery slowly discharges during storage and will become discharged during long-term
storage. Storage over one year is considered long-term storage. If the VR100 is to be stored long-term,
then protect the battery by following one of the suggestions listed below.
1.
Store the VR100 with the charger plugged in to an external power supply; OR
2.
Charge the VR100 overnight at least once a year.
Observe the recommendations under section 3.3.1 Maximizing Battery Service Life
