20.3.3 Battery Aged Alarm
If the battery runtime is significantly shorter than the specification, a low level technological alarm “ Battery Aged ” will
be presented. We recommend you to contact our company and replace it with a new one.
20.3.4 Battery Error Alarm
In the situation that the battery has a failure, a high level technological alarm “Battery Err” will be presented. In this case,
replace the battery or contact your service personnel.
20.4 Checking the Batteries
Battery capacity diminishes with use and age. To check the performance of the batteries, follow this procedure:
1. Connect the equipment to the external power supply and allow the batteries to charge uninterruptedly till it is fully
charged.
2. Remove the external power supply and allow the equipment to run from the batteries until it shuts off.
The operating time of the batteries reflects their performance directly. If the operating time of the batteries is noticeably
shorter than that stated in the specifications, discard the batteries or contact your service personnel.
NOTE
z
Life expectancy of a battery depends on how frequent and how long it is used. When properly cared for, the
lithium-ion battery has a useful life of approximately 2 years. For improper use models, life expectancy can
be less. We recommend replacing lithium-ion batteries every 2 years.
z
To optimize performance, a depleted, or nearly depleted battery should be charged as soon as possible.
z
Battery operating time depends on the device configuration and operation.
20.5 Charging batteries
The batteries can be charged only when they are installed in the equipment or using an device approved by the
equipment manufacturer. With the equipment turned off and at a temperature of 25°C (77°F), a completely discharged
battery charges to 80% of its capacity in approximately 2 hours, and to 100% of its capacity in approximately 3 hours.
Batteries charge at a lower rate with the equipment turned on.
Batteries should be charged at temperatures between 0°C (32°F) to 45°C (113°F). To optimize performance, a fully (or
nearly fully) discharged battery should be charged as soon as possible.
