    I leave mine ,on and have done every time i park up since this time last year, i suppose it depends on the charger, if it goes to float charge i cant see the harm, i was hoping it would preserve my batteries but i could be totally wrong, however my batteries are fine so it cant be too bad, running a battery right down is bad, they only have a certain amount of charge cycles before they are knackered

    Bill, that's very kind of you, but after being shot down a few times on here about batteries I no longer advise about batteries as others know better than me. I do however help at meets as and when I'm asked for a beer or two.(y)
    To the original poster I have a CTEK charger which I use whilst MH is parked up in garage ( sometimes for months on end ) and have done for past fours. Works for me.

    o
    The google brigade know nothing there is to much of the shooting down done by smart Arce know it all's.
    you spent your entire working life dependant on battery's if any one should know you should.
    john no battery's no comes no defence of the realm.
    and also if CTEK is good enough for you its good enough for any one

    I had a problem only last week because unknown to me the permanently on charge power plug from my garage had fallen out of the socket for some reason. I got a text warning from my tracker that voltage was dropping when I was away at our son's over Christmas. Managed to get back in time to save everything. So I am with @Don Quixote and @billthedrill

    Especially in the cold weather it will do more harm if it runs down than it will a full battery.
    Lead acid battery's do not have a memory but suffer if they run down with deposits on the plates.
    And the plates distorting from what I have ben told any intelligent battery charger will do the job

    Agreed Bill.

    An inteligent charger constantly monitors the battery voltage and only allows enough charge to top it up then it reduces to a very low charge rate to maintain the battery.
    A standard charger will continue to charge at a comparitively high current regardless of battery state of charge and could overcharge (boil dry)

    Assuming the Charger is of the "Intelligent" variety, then there is little or no reason to not use it, According to the information that came with mine it "monitors" the battery state and maintains (or introduces?) a light float charge where necessary. I have a C-Tek (type) charger which I leave on the Car whenever it is not in use, the battery (cheap) is now 5 years old and still appears to be OK.

    SOME of the older, "Caravan" (eg the early "plugin systems" type) charger units where ONLY for keeping the battery charged whilst Being used on a Hook up. They supplied a constant charge which could if left on continuously without any battery load drain damage the battery over time.

    I used a c tech charger permanently on my last mhome (RV) , now with Hymer leaving plugged in using system charger although with summer here may unplug and let solar do the job.

    Ctech or any passive charger is the way to go.

    With Gel you should get 10/15+ years if they are treated right and in your case I think you are. Enjoy

    Just recently returned to M/Homing after a 2 yr caravan break.....Not a Good move !!- But now the happy owners of a new Auto-trail 'Tribute' with a 'seargant' on board Charger/distribution -all-in-one unit. Having just also bought one of those 'Watt' meters from Fleebay.....set to answer my own Q's.
    After depleating the Hab battery down to circa 1/3rd capacity ....Left the 'Tribute' on Charge. Max Watts used to start with was just over 60w. after all day + 1 night ...this settled down to 10/11watts. [Apparently our onboard charger is a 4 stage max 12 amps. ]
    So MY conclusion is that I shall leave the M/H hooked up and let the clock timer keep things topped-up for a good few hours each day.
    The expense was one 'Watt' meter....£10.00
    & Plug in timer.....£2.
    And now busy checking all the Gadgets in the in the home ....Another useful toy to play with eh ?!?! (y)

    Hmm so would a 100w uv panel keep the batteries charged up in winter or is the uv too week in our latitude. ?

    I have my charger permanently wire into the mains, whenever I am on a hookup it is charged. I do the same for the cab battery using a CTEK charger.

    I am a fulltimer and keeping the batteries in tip top shape is important for me. My experience based on 7 years fulltiming is the more fully charged you can keep your batteries the longer they will last. Whether you use solar or a mains charger is not important. Letting batteries discharge especially over the winter will kill them quicker.

    The only exception to this is if you have old batteries and a cheap charger. I had a cheap charger and it burnt out when one of the batteries went down. I believe one of the cells went practically short circuit causing the charger to operated 24/7 and eventually the magic smoke escaped from it.

    We have a Bessacarr caravan that I use as a craft room. Its been round the back of the house for around four years now & the charger is never switched off. The caravan has a 110 amp leisure battery which is now around 8 years old & is still in perfect condition. We have a few systems for checking batteries including a heavy discharge tester & the battery passes with flying colours every time that it gets tested.

    Hi, as most battery chargers are also conditioners, no problem leaving it on. But check it when ever possible as things do go wrong. Also if possible give the battery something to do now and again.
