ECHARGE
Only use a battery charger supplied by or approved by Wood's Powr-Grip; other chargers may
reduce battery life. Charge the battery as soon as possible after any extended use of the DC
Vacuum Back-Up System, or whenever the battery gauge indicates diminished energy (see

ATTERY
T
EST
preceding). Temperatures above 70° Fahrenheit [21° Celsius] require the battery
to be charged more frequently.
CAUTION: Charge the battery only while the Back-Up System is not activated (see
OPERATION: When the Back-Up System is Not in Use). Using the Back-Up System when the
battery charger is connected to an AC power source could result in permanent damage to the
charger.
Identify the input voltage marked on the battery charger, and plug it in to an appropriate power
source. 3 Usually a battery takes no more than 16 hours to charge completely, after which the
charger shuts off automatically. The blue light on the battery gauge also turns on, to indicate
that the battery is fully charged. Following long-term use, a battery gradually loses capacity.
Replace it whenever the operating time between recharging is no longer satisfactory.

Perform this test only when the battery is not fully charged (see B

EST
preceding). While
the DC Vacuum Back-Up System is not activated (see OPERATION: When the Back-Up System is
Not in Use) and the battery charger is disconnected from any AC power source, use the battery
test button to take an energy reading on the battery gauge. Then plug the charger in to an
appropriate AC power source and allow a few moments for the battery gauge to show an
accurate energy reading. If the charger is functioning correctly, the energy reading should be
higher when the charger is plugged in.
