Question 1

This didn't come with a owner's manual. could somone send a link of the manual to upload, or send some screenshots, to know all of the features???

Accepted Answer

I've attached a video of the manual, which I have as a scanned PDF.  Why Amazon doesn't let us post a PDF is beyond me!  Anyway I converted the PDF to a video using Debut software.  
BTW... I use the charger all the time to keep my tractor, Gator, and vehicle batteries charged during winter months of inactivity.  I really like its ease of use and functionality.  Gets 5 stars from me...I have two of them, one at Ranch and one at home.

Question 2

Can this charge marine batteries?

Accepted Answer

Yes, will charge deep cycle 12v batteries. Select MOTORCYCLE for low amp charge or indefinite maintainer.  Or for faster charging, charge the battery in regular mode (STD/AGM,GEL/WET) and it will go through the cycle and charge to FULL. Then switch to MOTORCYCLE mode to maintain the battery for long periods. Once it finishes the motorcycle charge mode, it will indicate FULL and go into standby mode. If the battery voltage drops below FULL, the charger will restart and charge to FULL again and repeat the process, thus not overcharging the battery. I have tested this mode several times by turning on the headlights to force the battery voltage to drop while leaving the charger connected. Each time it has restarted and topped of the battery to FULL and gone back into standby. The enclosed instructions are crap. I found this information on a different branded but exact same model instruction. This Amazon website now shows these instructions.

Question 3

I have a condo so I can’t run a power cord to my parking spot. Can I charge the unit then charge my battery. If not do u kno of a charger that does?

Accepted Answer

No, it will not "charge" your battery. It will give you enough power so that you can start you car. The battery should charge while you drive or let it run for a while. If the car will not start after you have driven it, it's time to buy a new battery.

Question 4

Do battery charger operate well off a generator ?

Accepted Answer

I have never tried it with a generator, my utility supply is 115V and it works well. I think that it will work if the generator voltage is stable and at appropriate output voltage.
