If you leave the battery charger plugged in and constantly charging when the MWS is not in use, the battery life is maximized for the application. The charger will not overcharge the batteries.
The MWS has signal lights to indicate the battery status as follows. The following voltages are nominal (not exact) and should be used for reference.

Flashing | Warning! The batteries need immediate charging. |
Red | Voltage is below 22.5V. The station beeps continuously |
| to alert you of this condition. (Early models have red |
| lights instead of orange lights.) |
Flashing Yellow | Caution! The batteries are getting low. The voltage is |
| between 22.5V and 23.5V. |
Flashing Green | Go! The voltage is above 23.5V. The batteries are |
| charged to approximately 75% or better capacity. |
The 24VDC charger has a Power LED and five Percentage LEDs. When the charger is turned off (power LED off), the percentage LED shows battery status. The percentage LED flashes while charging to display battery status. When the batteries are fully charged, the 100 percent LED stays on.

If the CHARGE light does not turn on, make sure the charger is properly connected to the batteries and the charger has AC power.
If the READY light does not turn on after 18 hours, the batteries are deeply discharged. Call Technical Support or replace the batteries. If replacing batteries, you must use the same type of battery from the same manufacturer (as the ones provided with the MWS). Make sure the batteries are
