BATTERY

Do not expose your battery or cordless tools to water or
rain, or allow them to get wet. This could damage the tool
and battery. Do not use oil or solvents to clean or lubricate
your battery. The plastic casing will become brittle and
crack, causing a risk of injury.
Store batteries at room temperature away from moisture.
Do not store in damp locations where corrosion of
terminals may occur. As with other battery types,
permanent capacity loss can result if the pack is stored for
long periods of time at high temperatures (over 50

Always dispose of your battery according to federal, state
and local regulations. Contact a recycling agency in your
area for recycling locations.
Even discharged batteries contain some energy. Before
disposing, use electrical tape to cover the terminals to
prevent the battery from shorting, which could cause a fire
or explosion.

The RBRC™ Battery Recycling Seals (see "Symbology")
on your batteries indicate that MILWAUKEE
arranged for the recycling of that battery with the
Rechargeable Battery Recycling Corporation (RBRC). At
the end of your battery's useful life, return the battery to a
