## Questions & Answers

**Q: Can this handle a truck with 2 batteries?**
A: 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?**
A: 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?**
A: 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**
A: 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.
