Guidelines for Battery Pack and Charger Use
1. Your clipper, battery pack, and charger function has several interacting electrical systems. Good
electrical contact must be maintained in order for the motor to deliver full power, the battery to
charge properly, and the Refresh feature to operate. Limited or erratic performance caused by dirt
or age can be restored in the majority of the cases if you do the following:
A. Problem: Clipper motor starts and stops as if there was a loose electrical connection.
Solution: Remove the battery pack from the clipper. Examine the battery pack opening in the
clipper. Locate the two sets of motor contacts. Gently squeeze the metal leaves until they are
about 1/16" (1.6 mm) apart using a long pliers or similar. DO NOT squeeze the metal leaves
completely together or the battery pack will not re-insert.
B. Problem: Charger does not fully charge the battery.
Solution: Clean the battery pack bottom contacts (the portion inserted into the charging
pocket). Clean the charger contacts. Re-align the charger contacts. To clean the battery
pack contacts, rub gently with a pencil eraser until they are brightly polished. Use a cotton
swab and 91% isopropyl alcohol to remove any residue or dirt. Denatured alcohol can also
be used. Use care, as both products are flammable. Clean the charger contacts in the same
way - UNPLUG CHARGER FIRST. Make sure eraser dust and cleaners do not get inside the
charger base. To re-align the charger contacts, again make sure it is unplugged, and gently
pull the metal loops on the four contacts forward SLIGHTLY. Do not severely bend, deform,
or damage the contacts.
C. Problem: Charger does not exit the Refresh mode.
Solution: Clean the battery pack bottom contacts as noted above. Clean and re-align the
charger contacts as noted above.
D. Problem: Charger lights flash on and off as clipper or battery is moved side to side in the
charger pocket.
Solution: Re-align the charger contacts as noted above.
2. The charger base is designed to recharge battery packs that are at, or close to, room temperature
(25°C/77°F). If a battery pack is returned to the charger unusually hot or cold, the charger will
not enter fast charge mode. This is normal and the battery pack can remain in the charger.
Under certain conditions the charger may not fully charge a battery pack that has cooled from an
unusually hot temperature. Remove the battery pack for a few seconds, and return to the charger.
The charger will then enter a second fast charge mode.
3. Optimum charging results will be obtained if the charging unit is operated in a place where the
temperature is stable. Sudden increases in temperature may result in the battery pack receiving
less than a full charge. Avoid locating the charger near heat vents, radiators, or in direct sunlight.
4. Under normal room temperature conditions, there is no need to allow the charger base to cool
between charging battery packs. Completely discharged battery packs may be returned to the
charger base continuously for fast charge. If the room temperature is very warm, however,
allowing the charger to cool 5 minutes between battery packs is advisable. If the charger has
become too hot internally, fast charge will be discontinued. Remove the battery pack and replace
after a 5 minute cooling period; the charger will reset automatically.
5. It is normal for the charger to become warm to the touch during operation.
6. Disconnect the charger from the AC outlet if long periods of non-use are anticipated.
7. Never store batteries in a discharged condition. Recharge them immediately after they are
discharged.
8. Many factors influence the life of the battery pack. A battery pack that has received heavy use
and is over a year old may not give the same run-time performance as a new battery pack.

Use of the Refresh Feature
The Refresh feature works overnight by first discharging the
battery pack, and then quickly charging it. A trickle charge
maintains the battery at 100% for use the next day. This
allows a battery pack that has developed a "memory" to
perform like new.
A battery pack that receives monthly Refresh cycles will
last much longer than one that does not. Andis suggests that
the Refresh feature be used once per month at the end of a
business day. Using the Refresh feature overnight will ensure
that your work will not be interrupted while "Refresh" operates
(Diagram I).
1. The charger base needs to be plugged in for the Refresh
feature to work.
2. With the AGR+ clipper or AGR+ battery pack in the charger
base, press the Refresh button once. The green light will
blink while the battery is discharging.
3. The green light will stop blinking, and remain continuous
when the battery pack is charging once again (see
Sensacharge light sequences, page 4).
4. If the Refresh button has been accidentally pressed,
there are two ways to stop the battery pack from being
discharged. Removing the clipper from the charger, then
returning it, will cancel the Refresh operation and resume
fast charge. You may also unplug the charger base for
several seconds to reset the charger.
5. NOTE: The refresh cycle takes approximately eight hours to
produce a fully charged battery pack. The charge must make
accurate battery voltage measurements during this time.
If the charger does not exit the refresh cycle or does not
produce a fully charged battery, follow the steps on page 6,
number 2.
