14.8 Changing to Float Charge from Protection Charge (If applicable)

The manual procedure to change from protection charge to float 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 float 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 float

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 float 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 float charge. Thus, it is

not usually required to change the recharge

mode manually back to the float charge.
