Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged.
Charge the battery completely before using it for the first time. If the
battery has been stored for longer than six months, charge it before
use.
To protect the battery from deep discharge (5 volts or less), the
Trimble R7 system is designed to switch batteries or cease drawing
power when the battery pack discharges to 5.9 volts.
A battery that has reached the deep discharge level cannot be
recharged and must be replaced. The following recommendations
provide optimal performance and extend the life of your batteries:
• Fully charge all new batteries prior to use.
• Do not allow the batteries to discharge below 5 volts.
• Keep all batteries on continuous charge when not in use.
Batteries may be kept on charge indefinitely without damage to
the receiver or batteries.
• Do not store batteries in the receiver or external charger unless
power is applied.
• If you must store the batteries, fully charge them before storing
and then recharge them at least every three months.
Disposing of the rechargeable Lithium-ion battery
Discharge the Lithium-ion battery before disposing of it. When
disposing of the battery, be sure to do so in an environmentally
sensitive manner. Adhere to any local and national regulations
concerning battery disposal or recycling.
