Although the shaver can be
used for about 2 weeks after
a full charge (assuming
dry‑shave usages for 3
minutes per day), the usable
number of days might be
lower depending on how the

when used for wet shaving).
Apply oil.
Clean the shaver.
When the number of
operations per charge starts
to decrease, the battery is
nearing the end of its life.
