Charging Process; Important Safety Instructions For All Battery Packs - DeWalt dC540 Manual

• Do not operate charger with damaged cord
or plug — have them replaced immediately.
• Do not operate charger if it has received
a sharp blow, been dropped, or otherwise
damaged in any way. Take it to an authorized
service center.
• Do not disassemble charger; take it to an
authorized service center when service or
repair is required. Incorrect reassembly may
result in a risk of electric shock, electrocution or
fire.
• Disconnect the charger from the outlet
before attempting any cleaning. This will
reduce the risk of electric shock. Removing
the battery pack will not reduce this risk.
• NEVER attempt to connect 2 chargers together.
• The charger is designed to operate on
standard 230V household electrical power.
Do not attempt to use it on any other
voltage. This does not apply to the vehicular
charger.

Chargers
The DE9116 charger accepts D
NiMH battery packs ranging from 7.2 to 18 V.
The DE9135 charger accepts 7.2 – 18 V NiCd,
NiMH or Li-Ion batteries.
These chargers require no adjustment and are
designed to be as easy as possible to operate.

Do not probe with conductive objects.
Danger of electric shock or lectrocution.
1. Plug the charger (o) into an appropriate outlet
before inserting battery pack.
2. Insert the battery pack (d) into the charger. The
red (charging) light (p) will blink continuously
indicating that the charging process has started.
3. The completion of charge will be indicated by
the red light remaining ON continuously. The
pack is fully charged and may be used at this
time or left in the charger.

Charging process

Refer the table below for the state of charge of the
battery pack.
automatic refresh
The automatic refresh mode will equalise or balance
the individual cells in the battery pack at its peak
capacity. Battery packs should be refreshed weekly
or whenever the pack no longer delivers the same
amount of work.
To refresh your battery pack, place the battery in the
charger as usual. Leave the battery pack for at least
8 hours in the charger.
hot/Cold pack delay
When the charger detects a battery that is too hot
or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery has
reached an appropriate temperature. The charger
then automatically switches to the pack charging
mode. This feature ensures maximum battery life.
