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.
