14.8 Changing to Float Charge from Protection Charge (If applicable)
The manual procedure to change from protection charge to oat charge is shown in Step 1-3.This operation
applies to batteries after they have experienced over temperature condition.
See the Note below for an explanation of oat charge and protection charge.
STEP 1
Make sure that the EQUAL CHARGE LED is
“ON”.
STEP 2
Make sure that the “BATT FAULT1” warning
goes away.
STEP 3
Press “FLOAT/EQUAL” button for at least 0.5
seconds.
Procedure completed.
NOTE
The battery is normally being charged at oat
charge mode. To prevent thermal runaway of
the battery, this mode will automatically be
changed to protection charge when a “BATT
FAULT1” (Battery over temperature) warning
occurs.
In protection charge mode, the battery is
automatically charged at a voltage about 5%
lower than oat charge.
If the “BATT FAULT1” warning message goes
away and a programmed duration is elapsed
(about 24 hours), this mode will automatically
be changed back to oat charge. Thus, it is not
usually required to change the recharge mode
manually back to the oat charge.
