80 milli-amps non stop
Totally True - I got a free maintenance free battery of that voltage - it never came back to life
I highly recommend installing a battery disconnect switch near your battery so that you can simply disconnect it when not camping. There are many to choose from and (ebay, amazon...) and they work great. It keeps you from manually having to disconnect all the time and as noted, the gas detector will drain the battery.
And when you get another battery,,,,don't depend on a trickle charger to maintain it. A trickle charger will boil a battery. You want a maintainer, like a Battery Tender.
I wondered about this when I first checked it. Yes, I am sure I checked it correctly with my multimeter. Now, I’ll have to do some research on what to buy. Group 24, 27, 31 versus 6v in a series, or AGM blah, blah, blah.
I feel like I’m going to get overwhelmed quickly....
Yes, battery tender is what I have.
+2, The specs on most of these trickle chargers there is a low voltage limit. If the battery is at or below a certain voltage the charger will not even try to charge.
Propane detector. On many campers it's on all the time. I had a popup I would remove the fuse that the detector was on when storing the camper. Most detectors will chirp a few times when the voltage is removed. Try removing all the wires on either the negative or negative terminal and see what it does.
Although I suppose there may be an exception out there somewhere it would be more accurate to say of any trailer manufactured in at least the last 25 yrs that the propane detector (more commonly these days a combo CO/LP detector) would be hard wired into the trailer's 12 vdc system and would be on all the time. If one doesn't plug the trailer into shore power while it's being stored so the converter can maintain the battery charge or doesn't disconnect the battery when no shore power is available, either physically or with a disconnect switch, then the detector alone can over the course of a couple of weeks absolutely draw that battery down to the point where it's been destroyed.
On the battery side, I can recommend a good group 31 deep cycle. I got mine at Sam's club, Duracell (which is East Penn). $80 on sale. I can go 10 days with no hookups.
CO/LP detector and Radio is always drawing off mine unless I remove the in-line fuses.
**Go for the maintainer for the battery!!
I think a group 31 is a tad big for my needs. Majority of my camping, I’ll be hooked up. I’ll probably go for a 27 with a small Zamp solar panel.
I have a battery tender. Good to go now that I know I need to disconnect.
Did your dealer not go over this when you got your orientation for your new camper? Should have - now you know why.
Two trailers and no mention from either dealer about it.. I found out by asking others..
Same answer - should have, now you know why.
disconnect the neg side first the the pos. reconnect the pos side first then the neg.
A lead acid battery will self discharge ~5% per month just sitting on a shelf. I’d charge it up and do a test run see if it’ll run your lights and fans long enough for you. (Btw switch everything to LEDs it’s a cheeep solution to extend battery life) or after your tender says it’s charged and good to go take it to any auto parts store and they’ll test it for you. It’s probably damaged but may still be serviceable for a camping season or 2. But definitely put on a master shut off switch so u only loose that ~5% a month. I out mine right at the battery in the top of the battery box
They did not, probably to get me back in to buy a freaking new battery.
I still think that people "designing" campers do not camp in them. If so, they would all have a battery disconnect switch. They also, do not read reviews on their products.
Is that battery box something you bought, or something you created?
This is the battery box i used. I put a kill switch between the + terminal on the battery and the + post on the box.
I put a simple on off 2 position switch between the + side of my battery tender and the battery
