Zeno 5, Operation
Operation /
Discharging
Monitoring the
battery
charger or on a Leica Geosystems product deviates significantly from the actual
battery capacity available.
• The batteries can be operated from -20°C to +55°C/-4°F to +131°F.
• Low operating temperatures reduce the capacity that can be drawn; high oper-
ating temperatures reduce the service life of the battery.
When the battery is at 50% capacity, a low battery warning is displayed on the
Zeno 5 display. When the battery is at about 10% capacity, a very low battery warning
is displayed.
As Lithium-Ion batteries age, their capacity decreases gradually. Lithium-Ion batteries
are considered depleted with less than 60% of original capacity remaining after
approximately 2 years of use. Keep in mind that heavy usage or operating the
Zeno 5 at temperature extremes shortens the battery life.
Lithium-Ion batteries do not require conditioning cycles and the Zeno 5 battery
system (including chargers) requires no user interaction to maintain peak perform-
ance.
