RV batteries

[ScottBrownstein]

Well 100 milliamps is not much of a drain. Anything with a 5 volt microprocessor could sip that much. However, nothing is wired directly to the batteries without it's own tap and FUSE. I have 4 such home run loads. 1 of them is my Trimetric (32 ma display on, 16 ma display off), another the steps, probably the propane detector and who knows what the last one is. Actually, if I recall, my trimetric will indicate almost that much on my unit with the disconnect off. One of these days I am going to pull the fuses one at a time to find out what I am keeping powered with the disconnect off.

If you aren't plugged in for storage and worry about it, just pull the battery bank negative and it will all disappear!

100 ma will dissipate 2.4 amp-hours per day, or about 75 amp-hours per month. Can be significant in storage.

Turbs, is there any reason they have to be directly wired to the battery. I would like to have them wired on the other side of the disconnect, so when turned off there would be no draw. I disconnected all neg cables last week and the batteries are staying at 12.5 volts. Not bad I guess for below freezing every night and only in the 30's during day.

They wire them directly I'm assuming for amp draw, but also so you don't have to turn battery disconnect on and off whenever your raising or lowering jacks..... Probably so you won't forget [emoji848][emoji12]

Your slides are also or should be wired direct as well.

Why would we need amp draw on our batteries. Is it a safety issue?

He's referring to the jacks in use, large load, too much for your 12 Volt system to be switch w/ your existing disconnect circuit.

When the jacks aren't in use I am still getting a 0.1 amp/hr draw on the batteries that is coming from the Bigfoot system. This is what kills the batteries after a week. I don't think this is normal. I haven't heard anyone else complaining about their batteries being drained in a weeks time with the switch in the off position.

I thought I had all the unswitched items identified then I found that even though I had never hooked up a TV the antenna amplifier switch was on. Mine is located in the same plate as the coax plug and lighter socket on the ceiling over the entertainment center.

Does your amplifier run with the switch in the off position? We had our MH in for warranty repairs last week and they were the ones that told me the draw was coming from the Bigfoot system.

I have an entry level trailer and don't have a master switch or battery disconnect. I am ordering a disconnect switch because I have identified a few sources of battery draw. The LP/CO sensor, LED's in the fuse panel, LED's in the lighting switches and the stereo clock display.

"Brain" for the Schwintech slide out? Believe I've seen posts before that it needs to retain memory and has a small current demand when disconnect is "off".
