The MAX-610 is equipped with a Lithium-ion battery.
When fully charged, the battery should provide between 3 and 10 hours of
power depending on different factors such as: type of tests performed,
display backlight level, and connected accessories.
Note: When the battery level is very low, tests cannot be performed. Plug into AC
Mains supply for continued operation and to recharge the battery.
To maximize battery power of the MAX-610:
1. Lower the display backlight level using the application found in
Display and Language in the System Settings, when the MAX-610 is
used under low to medium light conditions.
2. Disconnect any unused USB or SD accessories.
3. Quit any running tests when the MaxTester is not in use.
4. Whenever possible, put the MAX-610 in suspend mode by pressing
until the suspend notification sound plays, about 2 seconds.
5. When not in use, turn the unit off by pressing for at least 4 seconds.
If the battery capacity remains low or outside the previously stated values,
it should be replaced. This could occur after 3 years depending on the
usage. You can evaluate the battery capacity through the Calibration
procedure, comparing the results with the Battery Capacity default value
of 10000 mAh. If your current battery capacity is lower than 8000 mAh,
replace the battery.
