DC9180
Product Service Plan
Page 1
The purpose of this document is to:
1. Determine if a DC9180, battery is OK or Failed
2. Provide suggestions for potential digital communication failures
• The Nano battery uses digital communication to “talk” with the
charger. Ensuring proper terminal engagement is essential to
the function of the system.
• This procedure suggests what key areas of the digital
communication system may be failed.

Step #1
• Place pack in good
charger for 5 minutes (note
only 90 seconds is needed to remove the pack
from sleep mode, but 5 minutes ensures the
pack has enough charge to perform the
following tests)
• Observe charger light
blink pattern
PASS
Let Pack cool for up to 1 hr
at room temp
•
Normal Blink Pattern after 5
minutes.
– see charger label for blink patterns
•
Hot/cold pack delay blink pattern

Step #2
• Place pack in good
charger for 5 minutes (note
only 90 seconds is needed to remove the pack
from sleep mode, but 5 minutes ensures the
pack has enough charge to perform the
following tests)
• Observe charger light
blink pattern
PASS
Move to digital
communication Check
•
Normal Blink Pattern after 5
minutes.
– see charger label for blink patterns
•
Problem Blink Pattern at any time

Step #3
• Place pack in known good
high drain tool such as a
drill, recip or circ saw.
• Observe full speed operation
PASS
1. Tool operates in full speed in a
consistent manner.
FAIL
1. Failure to run in full speed.
Inconsistent operation.

Step #4
• Place pack in known good
high drain drill such as the
DC925, DC927.
• Cycle the trigger 20 times as
fast as possible.
PASS
FAIL
1. Tool runs each time the trigger is
actuated.
1. The tool shuts off randomly and
may or may not come back on.

Digital Communication Check
If the battery shows a problem blink during
Step #1…
Perform the following tests to confirm
that the battery is communicating with the charger and
accepting charge
Page 6
Digital communication check #1
• Inspect the terminals of the battery to ensure good METAL
contact is exposed. Damaged, painted, or worn terminals
may interfere with the communication to the charger and
result is a problem mode blink.
PASS
FAIL
1. Terminals are in good condition
1. Worn, broken, painted or damaged
terminals

Digital communication check #2
PART A
•
Ensure the charger terminals are not broken or damaged. This can be done by
looking into the well of the charger and ensuring the openings of the terminals
match the openings in the plastic.

Digital communication check #2
PART B
1. After ensuring the charger terminals are not damaged, place the battery in the
charger. Ensure the battery is fully pressed into the well of the charger.
Charge for 90 seconds.
Battery not
fully seated
PASS
1. Terminals are in good condition
2. Pack is fully seated in the
charger and charges for 90
Seconds
FAIL
1. Bent or broken terminals
2. Pack is fully seated in the charger
and shows a problem mode blink
anytime within 90 seconds.

Note: The voltage at the terminals can not be used to accurately measure the
state of charge of the battery nor if the battery is defective. The electronics within
the pack alone as well as the interaction between the electronics in the pack and
the meter being used to measure the voltage may cause erroneous readings.
