For sure, but here in the Ontario provincial parks genset use just doesn't seem to be all that common - thankfully.


So ..... in Ontario how does one drycamp for a week in January in the woods without a generator?

We even used one or the other of our two generators 3 weeks ago in January drycamped in the Arizona sun to keep our batteries charged ... the nights were just cold enough so as to need the furnace cycling on and off all night several nights in a row. Solar wouldn't have kept up.

I don't get how one can be ready to camp anywhere anytime unless they have a generator along that at least occasionally gets used. [emoticon]

The vast majority of parks here in Ontario are closed during the winter for camping. The few parks that are open for camping restrict it to electric sites, along with electric sites offered for more formally arranged winter camping programs, so in both cases there's no need for a genset. I can't say that "no one" dry camps during the winter but I can't think of anyone I know that does in January when it's often - 20C here in Ontario.

I can likewise only think of 3 friends I know who own a genset for camping. I tried myself but found genset use was so infrequent I got tired of dragging it around and sold it. At my age the 50 lb weight of a 2K genset didn't impress me either, which is why I once considered a much lighter 1K, but it's too small to also run my house furnace in cases where we lose power during the winter so I've since concluded that owning a genset is for me pointless.

"Dual purpose"/"marine" batteries are a compromise. Any battery that advertises Cold Cranking Amps (CCA) or Marine Cranking Amps (MCA) is NOT a true deep discharge battery. These will have a short life when used in an RV.

While DEKA might not be considered in the same league as Rolls/Surrette or Fullriver, East Penn is as I recall the largest manufacturer of batteries in N America and presumably does have some expertise in the field, certainly more than forum pundits. [emoticon] Interesting that East Penn considers their DEKA Intimidator Series to be deep cycle batteries entirely suitable for RV use even though they do list MCA and CCA for these batteries. [emoticon]

Who do I believe? [emoticon] Hmmmmm, now that's a tough one ... not. [emoticon]

I vote for believing the published specifications, since expensive lawyers have to sometimes back them up.

I see nothing wrong with CCA and MCA values being published for a true deep cycle battery. These parameter values might merely read a little lower than those for a starting type battery. Not a big deal if one can live with the lower CCA and MCA values while at the same time getting true deep cycle performance when that is needed.

Bare in mind that two 6v batteries connected in series is essentially one BIG 12v battery...

Yep, it just depends on which set of ‘facts’ one wishes to use...

I'm not askin', I'm sayin' [emoticon] ... hands down, I'll believe the manufacturer that designs & builds these batteries over the Alternative Facts Brigade. [emoticon]
