Engages if the battery state of charge is 50% or higher or once the 

battery has been sufficiently recovered during STEP 5. 

The 

ampmatic

™ charge current monitoring and control 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 capacity.

Engages when the voltage has reached 14.4V (14.7V) for the first time 

during STEP 6. 

The 

ampmatic

™ current control program now delivers pulses of current 

to equalise the individual cells within the battery and optimize charge level. 
Charge time during this step varies between 10 and 120 minutes, influenced 

by initial battery State Of Charge and health as measured in STEP 3, and 

current draw by connected circuitry.   

For safety reasons there is an overall charge time limit of 72 hours for 

STEPS 4 to 7.

TEST after charge : 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 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%).

For batteries with a 

good state of health LED 

#6 (green) will remain 

on.

Exception:

 STD wet cell 

batteries with filler caps 

have a lower fully 

charged voltage: LED 

#6 remains on together 

with LED #7. 

MAINTENANCE CHARGE: LED #6 / 7 / 8 steady on 

according to state of charge measured during STEP 8.  

Float voltage setting: 13.6V nominal at 20°C (68°F) 

The float 

voltage is inversely regulated according to ambient 

temperature; i.e., voltage is increased at lower temperature, 

decreased at higher temperature.

Adjustment: -0.04V / cell / °C above or below 20°C (68°F). 
OptiMate 24-7 maintenance mode consists of 30 minute float 

charge periods followed by and alternating with 30 minute ‘rest’ 

periods, during which there is no charge delivered. This “50% duty 

cycle” prevents loss of electrolyte in sealed batteries and minimizes 

gradual loss of water from the electrolyte in batteries with filler caps, 

optimizing the service life of irregularly or seasonally used batteries.
During “float charge” a continuous LOW CURRENT PULSE IS 

DELIVERED TO PREVENT SULFATION, further extending battery 

power and life. 

If the OptiMate senses the battery has suddenly lost charge the 

program will revert back to STEP 7. 

VERY FLAT NEGLECTED BATTERIES: If the battery is deeply discharged (and possibly sulfated), remove 

from the vehicle or equipment and inspect the battery before connecting the charger for a recovery 

attempt.  
The charger’s TURBO recovery mode cannot engage if it senses that the battery is still connected to a 

circuit 

which effectively offers a lower electrical resistance than the battery on its own. However, if the 

deep-discharged battery is not removed for recovery, neither battery nor vehicle or equipment electronics will 

be damaged. 

Pay particularly close attention to the following  

A battery left deep-discharged for an 

extended period may develop permanent damage in one or more cells. Such batteries may heat up excessively 

during high current charging. Monitor the battery temperature during the first hour, then hourly there-after.
