FAQ

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.

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.

You can use any type of 12V-16V lead-acid/LFP battery as the source battery.

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.
