Definition
Explanation
Reconditioning
Describes the defined discharge and subsequent charging of the
battery with constant current. This allows the capacity losses of the
battery system to be eliminated or reduced.
Float Charging
The charge of an accumulator to compensate for its self-discharge
with the aim of keeping the accumulator fully charged.
Boost Charging
Indicates the charging of an accumulator with increased voltage and
a defined current in order to fully charge the accumulator as quickly
as possible.
Electrolyte
FNC® grid batteries are NiCd batteries and contain potassium
hydroxide (KOH) as electrolyte with an addition of lithium hydroxide
(LiOH). When handled properly, FNC® grid batteries are safe.
Contact with the electrolyte is excluded.
