The "EQUAL CHARGE" LED lit.
The "FLOAT CHARGE" LED unlit.

In equalized charge mode, the battery is charged for a set period of time at a voltage about
5% (depending on the type of battery) higher than normal (floating) charge, in order to
prevent variations in battery performance. This must be done about once every six months, in
spring and autumn if possible.
The TOSNIC-7000S UPS is equipped with a function that performs the equalized charging
process automatically when restoring the battery charge after a power outage or the like.
