INCLUDED: Fused battery clip set, standard battery clip set & weatherproof battery lead.
WARRANTY: 3-year limited replacement warranty.
How it works: As simple as 1-2-3!
Attach the fused clip set to the short input cable (side marked 12 – 16V) and then connect the OptiMate DC-DUO to a charged source battery e.g. your vehicle’s 12V battery. The OptiMate DC-DUO’s SAVE and CHARGE LEDs will blink together for 1 minute, indicating it is ready to charge a battery.
Within 1 minute* connect the output charge lead to the battery requiring charge, using the standard clip set or connect directly to the battery that may have the weatherproof battery lead already pre-wired. Charging proceeds when the SAVE or CHARGE LED turn full on. *After 1 minute the OptiMate DC-DUO turns off if not connected to the battery that needs charging. To re-start, disconnect from the source battery and then once again reconnect.
Wait until the green TEST LED blinks. ‘First Aid’ charging has been completed! Leave the charger connected for ‘365’ long term maintenance.
CHARGE YOUR 12V BATTERY FROM ANOTHER 12V BATTERY! NO AC POWER REQUIRED.
Recharge your trailered motorcycle, ATV or speed boat’s battery on the way to the venue.
OptiMate DC to DC draws power from your vehicle’s or an external 12V battery to save, charge and maintain another 12V battery. OptiMate DC to DC’s highly efficient long term maintenance mode protects the source battery, drawing only when the battery under charge needs it. The OptiMate maintenance mode keeps the battery at full charge, never overcharging, prolonging the life and improving performance of the battery. OptiMate DC to DC can save a deep discharged, sulfated battery from as low as 1 Volt.

Why won’t my OptiMate DC-DUO turn on?
As a safety measure the OptiMate DC-DUO has battery protection built in, meaning it will not charge if the source battery has a voltage lower than 11V.
Also, if already connected to the source battery, after one minute, the OptiMate DC-DUO turns off if not connected to the battery that needs charging. To re-start, disconnect from the source battery and then once again reconnect
What’s the supposed minimum capacity of the source battery?
Source battery capacity (in Ah) should ideally be 1.5 times higher than the battery to be charged. E.G. to recharge a flat 10Ah battery, you need a 15Ah source battery. The 12V SOURCE BATTERY should ideally be rated for deep cycle use.
What type of battery can I use as the source battery?
You can use any type of 12V-16V lead-acid/LFP battery as the source battery.
Ideal for 12V lead-acid & 12.8V / 13.2V lithium LFP (LiFePO4) batteries found in the vehicles / craft above.
BMS re-activates battery from sleep or deep discharge protection mode.
Fully automatic multi-step program brings the battery safely to full charge – Connect to the battery and OptiMate DC-DUO does the rest, no supervision required!
