Battery Pack Operation
The equipment is powered by a lithium-ion battery. The battery
pack is completely sealed and maintenance free.
Battery Charge Level Indicator
The battery pack is equipped with a push button for checking
the charge level. Simply press the push button to read off the
battery charge level from the LEDs of the battery indicator:
• All 3 level monitoring LEDs are lit: Battery charge level
is high.
• 2 level monitoring LEDs are lit: Battery charge level is
decreasing. Stop work as soon as possible.
• 1 level monitoring LED is lit: Battery is flat. Stop work
IMMEDIATELY and charge the battery. Otherwise the
battery’s service life will be greatly shortened.
NOTE: If the charge level button does not appear to be
working, place the battery pack on the charger and charge as
needed.
NOTE: Immediately after using the battery pack, the charge
level button may display a lower charge than it will if checked
a few minutes later. The battery cells “recover” some of their
charge after resting.

WARNING!
Charge only iONMAX 40 V System lithium-
ion battery packs in compatible iONMAX iCHRG40 lithium-ion
battery chargers. Other types of batteries may cause personal
injury and damage.
To reduce the risk of electric shock, do not allow water to flow
into the charger's AC/DC plug.
When to Charge the iONMAX 40 V
System Lithium-Ion Battery
NOTE: The iONMAX 40 V System lithium-ion battery packs
do not develop a "memory" when charged after only a partial
discharge. Therefore, it is not necessary to run down the
battery pack before placing it into the charger.
• Use the battery charge indicator lights to determine when to
charge your iONMAX 40 V System lithium-ion battery pack.
• You can "top-off" your battery pack's charge before starting
a big job or after a long day of use.
Charging the Battery
1. Open the battery compartment cover. Slide the push lock
button on the battery to remove the battery pack from the
base unit (Fig. 12).
2. Check that the mains voltage is the same as that marked
on the rating plate of the battery charger. Then, insert the
charger's plug into the electrical wall outlet. When you
plug in the charger, the top green light will illuminate and
stay green (Fig. 13).
