Customer Questions & Answers

  • Question: Is this charger suitable for all types of 12 volt batteries?

    Answer: Yes, it is designed to charge deep-cycle, gel, and AGM batteries.
  • Question: How does the winter mode work?

    Answer: Winter mode optimizes the charging process in low temperatures for better performance.
  • Question: What safety features does this charger have?

    Answer: It features automatic shut-off and switches to maintenance mode when charging is complete.
  • Question: Is this the same Viking 4 amp fully automatic microprocessor controlled battery charger/maintainer Harbor Freight sells for $29.99?

    Answer: It's the exact same one. See the '63350' part number on the lower right corner of the box? Type that in Harbor Freight's site.
  • Question: Would this unit work to maintain a 24 volt system on my diesel truck?

    Answer: Your diesel pickup is more than likely not a 24v system. It has 2 batteries wired in parallel and remains 12v. I use one of these on my Ram, and you can connect to the driver's side battery and it also charges the passenger side. It is also much cheaper at HF.
  • Question: Should the charge voltage (on a 12V car battery) and 'gauge bars' repeatedly go up and down while charging?

    Answer: Mine does all the time. I believe that it has something to do with the 'Maintain' function and/or the temperature function.
  • Question: When charger shows bad battery, is the battery no good?

    Answer: Not necessarily, check to make sure you’re on the right 'mode' and try to charge again.
  • Question: Can this charger be used to charge Lithium battery's?

    Answer: I have one but don't want to risk a $800 12v 100ah lifepo4 battery to try it out. I just bought a $65 12/24v 15 amp charger specifically for lifepo4.
  • Question: Specifically, what does the winter mode do?

    Answer: I would like to know the same thing. Can't find anything about it anywhere.

Fully Amutomatic Microprecessor Battery Chargers 708088999789 Editorial Review

The Viking 4 amp fully automatic microprocessor controlled battery charger/maintainer is a great device for long-term storage of batteries, especially during the winter months. It can be used for motorbikes or RVs, and it is simple to use and set up. However, some customers feel that it is too expensive for its limited capabilities. Some reviewers have also experienced issues with the charger not working when the battery is too low or too high, but overall it is a good product that performs as advertised.
