Charge time : Program 1 & 2: 15min to 2hrs. Program 3 & 4: up to 6 hours.
IMPORTANT: Read section VERY FLAT NEGLECTED BATTERIES prior.
A battery diagnosed as deep discharged undergoes a multi-step reconditioning
process appropriate for the selected battery chemistry and connection method
(direct / CAN-bus), is tested to confirm it's state of health before proceeding to
STEP 6.
RECOMMENDED: Always charge a deep discharged / low voltage battery after it
has been disconnected from the vehicle's circuitry, to avoid adverse influence by
the vehicle's circuitry on charge & test progress.
Program 1 (Pb) : If vehicle circuiry has been detected charge voltage is limited to
14.5V. Otherwise voltage may briefly rise as high as 22V to overcome sulphation
within the battery. A sufficiently recovered battery proceeds to STEP 6.
Program 2 (Pb + CAN-bus) : Maximum charge voltage is limited to 14.5V. A
healthy Pb (lead-acid) battery will progress to STEP 6.
Program 3 (LFP) : OptiMate's propiertary Lithium reconditioning mode is
activated. Current starts at 0.2A and will increase towards 0.8A depending on
charge progress. The battery's ability to accept and hold charge is monitored. A
healthy LiFePO battery will progress to STEP 5 within 6 hours.

Program 4 (LFP + CAN-bus) : The battery's ability to accept and hold charge is
confirmed. A healthy LiFePO
Program 3 and 4: TEST LED #8 (red) flashing rapidly - Abnormal charging or
battery damage has been detected and charging has been suspended. Consult
the TROUBLESHOOTING GUIDE on page 11.
Engages if the battery state of charge was 50% or higher (as tested in
STEP 3) or once the battery has sufficiently recovered during STEP 4 & 5.
A current of up to 1.25A is delivered to the battery up to a voltage of 14.3 - 14.5V.
NOTES: For a healthy battery charging always starts at STEP 6. A battery with a
higher level of charge will progress faster through STEPs 6 and 7.
Engages when the voltage has reached 14.3V for the first time during STEP
6 - CHARGE mode.
The charge program now equalises the individual cells within the battery and
optimizes charge level. Voltage may vary frequently between 13.6V and 14.5V.
NOTE: Charge time is usually extended if there is higher than expected current
draw by connected circuitry or battery health is less than optimal.
For safety reasons there is an overall charge time limit of 48 hours for STEP
4, 5, 6 and 7.
Delivery of current to the battery is interrupted for 30 minutes** to allow the
program to determine the battery's ability to retain charge.
** IF charging started in SAVE mode (LED #3) the voltage retention test is
extended to 12 hours to confirm battery health.
LED #6 (green) will remain on for batteries able to hold 90% or higher state
of charge (SOC%), otherwise the TEST result is adjusted lower (LED #7, LED #8)
in real time according to the measured battery voltage. Consult the table on page
2 to match TEST LED indication to an estimated state of charge percentage
(SOC%). Also read section "NOTES ON TEST RESULTS" below.
