TEST cell damage
The battery is deep discharged OR the battery voltage does not match
the selected voltage. (Battery voltage is lower or higher than is
considered normal).
1. Confirm battery's nominal voltage matches the selected voltage.
If not, disconnect charger from battery. Select correct voltage.

2 Reconnect battery to charger.
If it matches the selected voltage (16V), go to point 2 below.

2. For a deep discharged 16V battery (16V selected): Push and
hold button for at least 3 seconds until LED #1a / #1b and LED #3

charged OR voltage is between 0.5 to 13.1 Volt (16V: 0.5V <> 16.3V)
IMPORTANT: Read the section VERY FLAT NEGLECTED BATTERIES on
the preceding page.
A very flat battery should progress to STEP 7 within 4 hours, unless
damage has been detected, then charging will be suspended and TEST
LED #8 (red) will flash rapidly, indicating the battery may have suffered
permanent damage or a professional assessment is required.

VERY LOW VOLTAGE SAVE : Current starts at 600mA and will
4
increase to 1.25A depending on charge progress. If the voltage did not
rise above 8.8V (16V: 11V) within 2 hours, charging will be suspended
and the TEST LED #8 (red) will flash, indicating the battery may have
suffered permanent damage or a professional assessment is required.
LOW VOLTAGE SAVE :
Charge current is increased to 2.5A*. The battery's charge acceptance
is monitored for unusual behaviour.
*Charge current is increased to 6A following a BMS reset.
A deep discharged battery that may not hold sufficient voltage to
power its own BMS system will automatically receive repeated BMS
reset pulses during SAVE mode so that charging may continue. If
charging did not continue, use the MANUAL CHARGE ACTIVATION mode
described under STEP 1.
TESTING (2 min) - The battery's ability to hold charge is monitored. A
healthy LiFePO
will be suspended and TEST LED #8 (red) will flash rapidly, indicating
the battery may have suffered permanent damage or a professional
assessment is required.
