GUIDELINES FOR BATTERY PACK AND CHARGER USE
1. A nickel-cadmium battery pack, such as the one used with the Andis Cordless Clipper, may not
recharge to full capacity if several conditions exist:
A. The battery pack may develop a “memory.” This condition is caused by recharging the battery
pack after every brief use of the clipper. The memory effect can be eliminated or prevented by
using the Refresh feature once a month.
B. New battery packs, or packs that have been unused for a period of time, may not accept a full
charge. This is a normal condition, and does not indicate a problem. The battery will accept a
full charge after several cycles of clipper use and recharging.
2. Your clipper, battery pack, and charger function as 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 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.
3. 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.
4. 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.
5. 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
