charge of LiFe.
Charge the optional FT2F1700BV2/2100BV2
(LiFe) battery with the special charger in accor-
dance with the instruction manual supplied.
When the battery will not be used for a long time,
to prevent it from deteriorating we recommend
that it be kept in about the half capacity state in-
stead of fully charged. Also be careful that the bat-
tery does not enter the over-discharged state due
to self-discharge.
Periodically (about every 3 months) charge the
battery.
