Viewing Battery Status

The Battery Status Icon and Battery Voltage Indicator indicate the
battery charge level as follows.
• If the battery charge level is at full capacity, four solid bars will display.
• If the battery is partially charged, two or three solid bars will display.
• If the battery is nearly empty, one solid bar will display. The unit should
be charged at this time.
• If the battery is completely empty, four blank bars will display. The
unit MUST be charged at this time or the unit's built-in low voltage
protection will activate. The empty Battery Status Icon will flash for
a short period of time before automatic shut down. The unit will not
operate until the battery is recharged.

Charging/Recharging

Lead-acid batteries require routine maintenance to ensure a full charge
and long battery life. All batteries lose energy from self-discharge over
time and more rapidly at higher temperatures. Therefore, batteries need
periodic charging to replace energy lost through self-discharge. When
the unit is not in frequent use, manufacturer recommends the battery
should be recharged at least every 30 days and after each use.
