Should I get a group 31 battery?

My boss bought an AC Delco Voyager group 29(31) battery for his boat. It doesn't fit the boat and he has offered it to me for what he has in it, ($25, new old stock, "blem").

I currently have a group 24 Interstate that's a couple years old. I'm not having any problems and normally camp with hookups. We will be taking a long trip this summer and will spend a couple nights without power while traveling.

Can't beat the price on the new battery but I don't think I really "need" it. Is it worth the hassle to change battery box and switch over to the bigger battery? I may have to redo the mount if it's not wide enough.

  • Delco made both types and both are sealed tighter than a you-know-what in a horsefly hatch.

    Delco's regular calcium/calcium flooded battery is garbage. Slosh the battery. If you hear liquid IMHO ten dollars would be wasting money. Delco's AGM is a better battery but be advised it has .045" positive plates. That is a $25.00 battery. If flooded it is worth core value in exchange.
  • A new AGM type 31 for $25? Buy it. You can easily triple your money on it if you decide you don't need/want it.
  • For $25 & if it is a "sealed" deep cycle battery, AGM or Lead Acid, buy it.

    A sealed battery can be stored anywhere in your TT & be used when needed. It would make for a good back-up battery & if your current one goes south, then use the Voyager as a replacement.
  • I googled the battery and it came up agm. Perhaps that's just what they want me to see first.

    An excellent price on a battery, but I don't get where this series is AGM. Following from the ACDelco webpage:

    When durable performance in an economical package is what you're after, rely on the Voyager II Marine Battery. These ACDelco Advantage / 60-Series deep cycle batteries feature large reservoirs above the plates to provide ample electrolyte reserve for maintenance-free performance in a variety of environments.

    Notice, this is Voyager II, 02, TWO. If it's "Voyager" without the II, then it's not a Deep Cycle battery. Be sure what he has is what you need.
  • I didn't know it was AGM, just thought it was deep cycle marine. I haven't even looked at it.

    Only catch, no warranty. For $25, who cares.

    He got it cheap from our battery supplier.
  • $25 for an AGM battery! Wow... that's really cheap. What's the catch?
