Q: Can this handle a truck with 2 batteries?

If it is a 12V system, then you can use it to charge your battery. If it is a 24V system, then you cannot use it to charge your battery.

Q: Can I replace the 3 amp fuse on the included o-ring cable adapter with a 5 amp fuse?

I don't know but using a larger fuse may damage the unit.

Q: Hello, How many hours does a 12 volt car battery need to be fully charged?

The number of hours for a 12 volt car battery needs to be fully charged depends on the size of the battery and the level of discharge. A general guideline that I go by is the battery size in Amp Hours (AH) and divide by the Amp rating of the charger, so I figure a 60 AH battery might need 12 hours (60AH / 5A). Ambient temperature, age of battery and chemistry type of the battery can also have an influence on the amount of time to reach a full charge.

Q: Can this be used as an onboard battery maintainer

Thank you for your interest in HULKMAN! The compatibility of our car battery trickle charger depends on the battery capacity, which should fall within the range of 15Ah to 120Ah.
