USE GUIDELINES FOR LITHIUM-ION BATTERIES
1. The lithium-ion battery included with your shaver does not develop a “memory
effect” like a nickel-metal hydride (NiMH), or nickel cadmium (NiCd) battery. You
can return the shaver to the charger at any time for a full charge, or even use the
battery before a charge cycle is complete. Like most rechargeable batteries,
lithium-ion batteries perform best when used frequently.
2. For maximum battery life, store the shaver in a partially discharged condition if it
will not be used for several months. To discharge the battery, run the shaver until
it automatically shuts off.
3. Avoid locating the shaver near heat vents, radiators, or in direct sunlight.
Optimum charging will result where the temperature is stable. Sudden increases
in temperature can result in the battery receiving less than a full charge.
4. Many factors influence lithium-ion battery life. A battery that has received heavy
use or is more than a year old may not give the same run-time performance as a
new battery pack.
5. New lithium-ion batteries, unused for a period of time, may not accept a full
charge. This is normal and does not indicate a problem with the battery or charger.
The battery will accept a full charge after several cycles of shaver use and
recharging.
6. Disconnect the charger or the shaver from the AC outlet if extended periods of
non-use are anticipated.
BATTERY REMOVAL
At the end of shaver life, please remove the battery following steps 1-6 below and
dispose of it properly.
