WARNING: Do not allow any liquid to get inside charger. Electric
shock may result.
• DO NOT attempt to charge the battery pack with any charg-
ers other than the ones in this manual. The charger and bat-
tery pack are specifically designed to work together.
• These chargers are not intended for any uses other than
charging D WALT rechargeable batteries. Any other uses
E
may result in risk of fire, electric shock or electrocution.
• Do not expose charger to rain or snow.
• Pull by plug rather than cord when disconnecting charger.
This will reduce risk of damage to electric plug and cord.
• Make sure that cord is located so that it will not be stepped
on, tripped over, or otherwise subjected to damage or
stress.
• Do not use an extension cord unless it is absolutely neces-
sary. Use of improper extension cord could result in risk of fire,
electric shock, or electrocution.
• An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that is
16 gauge has more capacity than 18 gauge. When using more
than one extension to make up the total length, be sure each
individual extension contains at least the minimum wire size.

• Do not place any object on top of charger or place the
charger on a soft surface that might block the ventilation
slots and result in excessive internal heat. Place the charg-
er in a position away from any heat source. The charger is ven-
tilated through slots in the top and the bottom of the housing.
• 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 reassem-
bly 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 household
electrical power (120 Volts). Do not attempt to use it on any
other voltage. This does not apply to the vehicular charger.

Battery Performance

Some chargers have a Tune-Up™ feature that optimizes battery
pack performance. Your charger may provide automatic Tune-Up™
mode or manual (i.e., push button) Tune-Up™ mode. For informa-
tion on this feature, please see the appropriate section below.
Because batteries slowly lose their charge when they are not on the
charger, the best place to keep your battery pack is on the charger
