CONNECTING THE CHARGER TO THE BATTERY
1. Disconnect solar panel before making or breaking DC / battery
connections.
2. If charging a battery in the vehicle with the battery clips, before making connections, first check
that the battery clips can be safely and securely positioned clear from surrounding wiring, metal
tubing or the chassis. Make connections in the following order:
First connect to the battery terminal not connected to the chassis
(normally positive), then connect the other battery clip (normally
negative) to the chassis well away from the battery and fuel line.
Always disconnect in reverse sequence.
3. When charging a battery out of the vehicle with the battery clips, place it in a well ventilated area.
Connect the charger to the battery: RED clamp to POSITIVE (POS, P or +) terminal and BLACK clamp to
NEGATIVE (NEG, N or –) terminal. Make sure the connections are firm and secure. Good contact is
important.
4. If the battery is deeply discharged (and possibly sulphated), remove from the vehicle and inspect
the battery before connecting the charger for a recovery attempt. Visually check the battery for
mechanical defects such as a bulging or cracked casing, or signs of electrolyte leakage. If the
battery has filler caps and the plates within the cells can be seen from the outside, examine the
battery carefully to try to determine if any cells seem different to the others (for example, with white
matter between the plates, plates touching). If mechanical defects are apparent do not attempt to
charge the battery, have the battery professionally assessed.
5. If the battery is new, before connecting the charger read the battery manufacturer's safety and
operational instructions carefully. If applicable, carefully and exactly follow acid filling instructions.
OptiMate Solar DUO can charge and maintain the following battery types:
STD : 12V 'wet' cell / refillable lead-acid battery. Liquid acid can leak out if battery is turned on its
side.
AGM : 12V sealed lead-acid battery, acid is fully contained within the battery. A 12V AGM battery holds
a higher charged voltage than STD lead-acid batteries.
GEL : 12V GEL sealed lead-acid battery, acid is fully contained within the battery. A GEL battery holds
similar charged voltages to AGM.
LFP : 12.8V / 13.2V sealed Lithium Ferrous Phospate battery. Lithium batteries contain no acid. A LFP
battery holds a higher charged voltage than AGM / GEL.
Important - OptiMate Solar DUO is suitable ONLY for 4 series cell Lithium Ferrous Phosphate or Lithium
Iron Phosphate batteries. DO NOT ATTEMPT TO CHARGE any other type of Lithium battery.
When connected to a solar panel and a battery the OptiMate Solar DUO charge controller will
automatically alternate between two program modes, MONITOR (Night / no sun) and CHARGE (Day /
sun), depending on solar panel's power delivery.
A. MONITOR MODE - When the solar panel stops delivering power (sun has gone down in the
evening or cloud covers sun) the OptiMate Solar DUO controller changes to BATTERY MONITOR
mode and will now indicate battery charge level every 3 seconds.
LED 2, 3, 4 or 5 indicate battery charge level.
