Immediately following connection to a battery there may be a 1-2
second delay before charging progresses, during which time:
Battery State Of Charge is measured to determine charge requirement
and duration of the State Of Health test in STEP 9. A low battery will be
tested for 12 hours.
safeTº: Ambient temperature is measured to determine safe charge
current parameters. See page 2 for temperature (°C/°F) and
k
corresponding Ampére (A) values.
The battery SAVE mode engages if the battery is less than 50% charged
OR voltage is between 0.5 to 13.1 Volt.
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 0.4A and will increase to
0.8A depending on charge progress. If the voltage did not rise above
8.8V 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 1.25A*. The battery's charge acceptance
is monitored for unusual behaviour.
*Charge current is increased to 2.5A 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

be suspended and TEST LED #8 (red) will flash rapidly, indicating the
battery may have suffered permanent damage or a professional
assessment is required.
The ampmatic™ CHARGE program automatically determines
the most efficient rate of charge current for the connected battery,
according to its state of charge, state of health, and electrical storage
(Ah) capacity. The delivered current may be anywhere from 1.25A to
5.6A (within normal safeTº temperatures, see page 5). For batteries
with an electrical storage (Ah) capacity less than 6Ah charge current is
automatically adjusted lower to an average equal to battery Ah capacity,
e.g. a 2.5Ah / 2500mAh battery receive an average of 2.5 Amps.
NOTE: For safety reasons there is an overall charge time limit of 24
hours up to STEP 7.
