    Well I never....(skip to the bottom for result if my waffle drives you crazy)

    As a newbie I have something to give back to all you loveley people who have been helping me so here goes the report on the

    Ctek 7000 charger.

    Cons first...
    The instructions are so bloomin small that with failing eyesight my brain couldnt absorb the content..so I scanned them on fit to page and hey presto. If I can work out how Im gonna post the instructions in pdf format so you can see if this device is applicable to your situation.

    Pros.
    The device has different settings...normal..(connect and forget).. dont worry if you dont know if your battery is normal or not...the charger will tell you...geezus its clever.

    snowflake for charging in the cold or if its a specific type of battery...ie non wet acid lead (sealed or unsealed)..unless its cold of course.

    recondition...a specific setting if you have a totally discharged battery as apparently the bulk of the acid drops to the bottom and therefore its weaker on top and seemingly this setting sorts that out....which saves the muscles from lifting the thing and shaking it I guess...

    supply...connect the charger to the terminals not the battery and it acts as a supply whilst you swop batteries so you dont loose precious settings in the computer side of your vehicle like car radio codes alarm codes etc.....(just in case you are thinking you could crank off it in this situation to get an engine with a dead battery started the answer is I dont know and it doesnt say but the wires are thin and I dont think they look sturdy enough to crank off....so Ive emailed ctek to find out...what a plus if you can

    Ok so the test...first I got a brand new 110 a/h leisure battery as I need stored power and crank power for the onan genny.....came supplied with half a charge..so on normal setting the Ctek took 8 hours to go through its processes on normal setting..
    Normal setting
    1. it analises the battery to see if it needs desulfating and if it does the first lamp in a 4 lamp stage starts to flash...when it stops flashing it is steady on gently charging until there is enough charged to proceed to lamp 2 where the bulk charging is done....it moves onto lamp 3 after what is going to be hours less or more depending on the size of the battery.
    When fully charged off to lamp 4 it goes BUT this is where its going to tell you after a specific time period if your battery is faulty because the clever chappie secretly switches off....the light is still lit so you just have to trust that this process is going on....and then secretly it switches itself back on and annalises the drop in charge...(all batterys loose their charge if left to their own devices)....if the drop is acceptable to the charger then it maintains it indefinately until you want to use it ...this last stage maintentace is using very little of your electricity bill.
    If the charger thinks anything it is wrong it tells you and you would change manually to the "recondition the battery mode"

    Interesting isnt it that a brand new battery takes so long to charge up...imagine if I had just bunged it into the rv..I would have been killing it from the first moment I used it.
    Ok the recondition mode which I used on my 4 year old battery is as follows..
    You manually select recondition mode,
    The charger starts in normal mode and desulfates if needed mixes the acid back up and then charges the battery and then analises if its holding its chargr and then maintains it. The reconditioning takes between 30 mins and 4 hours the charging takes many many hours.


    Result....success..a dead battery revived and according to the charger passed all tests.

    Did I accept that....nahhhhhhhh

    The acid test (sorry about the pun)

    Back onto the rv went my now resusitated 4 year old dead battery.
    In the past after a full charge on a halfords bog standard battery and then kept in the rv for w week with shore power charging it the leisure battery lasted...well about 6 attempts to start the genny then it was dead.

    Now....well I left all the lights in the rv overnight which would previously kill the battery but today when I got up it was not even half empty....so at 6.30 I switched everything I could thats 12 volts and its still not down to half empty...(I bought an accessory that are lazy boy eyelet fittings that attach to the battery and it has a display ..red (dead or nearly but certainly get it charged as sulfation is taking place) amber..(ok there is plenty of time for another beer, and watch the match but then you must get up off your fat but and charge me) green (all is ok master..no sweat..chill man) this display is watertight and I have it slightly hanging down so I just need to squat and I can visually see the charge state held in the battery and if charging is needed then I just plug the charger into the lazy boy fitting and off we go ...yes I know there is one on board my vehicle but I dont trust it and it a piece of poo....its showing green fully charged by the way.

    So it looks like my dead battery (but remember it had hardly ever been used) has been revived....which is a bummer because I bought a new one didnt I???????? doh.

    Next..the 4 year old vehicle battery 70a/h is getting the same treatment.

    So success...it did exactly what it said on the can. If anyone considers themselves to be near stansted airport and wants to see if their dead battery can be revived before they shell out £100 for this charger then Im glad to process it for you.
    Ctek make cheaper multi chargers and the price is related to the a/h of the battery you want to charge.
    The chargers will hower MAINTAIN a/h batteries alot higher than the a/h it can PROCESS...
    I was advised to get one that was 10% higher rating than I needed and so I needed the 7000 unit for my 110a/h battery.

    If you have two lower rated batterys however but togeter they come to a higher a/h then you could buy a cheaper ctek which individually would PROCESS the batteries and then bung them back on the vehicle together and your lower rated charger would still MAINTAIN the twin set...does that make sense.

    For everyone who skipped from the start to avoid my waffle...yes it works my 4 year old dead unused battery is living again.

    If I find any pitfalls with this charger I will report it asap...btw as long as the mains plug is in the dry ..the charger is ok outside but check its specs to see if it matches your situation.

    Its a long report but its an expensive problem...I hope this helps. if this is of help and admin want to post this elsewhere in a more appropriate place as well then please do...

    Hi Snowbird have you ever tried one from Aldi and Lidl at 12 quid ? Admittedly they only charge at 4 amps but try finding another 3 stage charger for £12 :thumb: They do the exact same job as the 50 quid Ctek which in turn does the same job as the £200 plus ctek albeit a lot slower - Been using a Aldi charger to keep vehicle battery topped up for the last 3 yrs without problem

    Same question Jim have you ever tried one ? It charges any type battery -FLA OR GEL - up to 120amp hr Mine has brought my van battery back ( 95 amp with 800 amp cc )a few times from a barely lit ignition light ( after leaving several weeks with alarm on ) after forgetting to connect it up
    I have a 22 amp charger fitted into the rear of the van but always carry one of the Aldi ones as a spare or in case I leave the cd player on which has happened more than once :Rofl1: I have also taken the L/B off to get the engine going when stuck but that is another story :Doh:

    Anyone looking for a cheap decent charger could do a lot worse than the Aldi one on offer this week or the Lidl one next Thursday :thumb:I usually keep one or two as spares but end up either lending them out never to return,:Doh: or giving them away :Rofl1:

    Well I have the Optimate 3 which is similar to the Aldi charger,have had it for years,and as a battery charger goes, its very good,so must agree with the posts re the Aldi charger.
    There is one drawback...and that is it is not man enough for deep discharged or desulphating big batteries like the ones we have in motorhomes,thats why I have a mountain of dead batteries in my yard.
    I have collected them up from farms and haulage yards as well as MH shows where they have been abandoned.I have huge battery banks on both campers and solar panels to keep them charged,but I know that they will want desulphating one day,so its better to do them sooner rather than later.We used to call it preventative maintenance when I had trucks.Funily enough I picked one up only this morning in Aldi,openend the box and there was somthing in there the size of a fag packet,and just as heavy with Made in China proudly printed on it.Neadless to say am not trusting my battery banks to that.:Smile:

    I have an auto x5 also Terry. had it a few years charges small mower battery to large leisure battery and you can leave it on for weeks without bothering about ruining your battery ideal if you have a second car you do not use very often :thumb:

    That's all well and good Terry but does the Aldi one have several different coloured lights?

    Aldi v ctek

    If thats the case then I blobbed big time spending 100 quid...and for part timing with access to a house it sounds great if it does as you say.

    My plan is to full time so I got this for quality and durability too plus its useable in the rain apart from the plug.

    For 12 quid you cant go wrong ...methinks I may have blobbed:cry:
