  1. Sterlings options on my inverter charger for AGM are:

     

    AGM 1 14.1A Absorbtion 13.4A Float

    AGM 2 14.6A Absorbtion 13.7A Float

     

    Open Lead Acid 14.8A Absorbtion 13.3A Float

    Calcium 15.1A Absorbtion 13.6A Float

     

    He also says that these are merely options and you should ask the battery supplier and choose the option that fits the closest.

     

    I'm pretty sure you wont come to any harm by charging at a lower max voltage, you merely won't get charged as fast as you would at the higher voltage.

  2. I proves that they dissolve in water. Not surprising really, many metals oxidise in water when unprotected

     

    Richard

     

    Agreed. But how long would a typical anode last if it is merely dissolving in the water - rather than wasting due to electrolytic, (??), action.

     

    If they are merely dissolving in water, surely they last a very long time, and you only get conned once every long time?

     

    Mine weren't new when I bought the boat, and I didn't replace than as they looked OK. I'll see how they look when we lift in a year or so.

  3. In my opinion, what the hell's going on is that the English canal community has been conned into dissolving lumps of metal into the cut for no good reason

     

    Richard

     

    Isn't the fact that they dissolve some kind of proof that they are protecting something. If they aren't protecting the boat, but something in the canal, surely they would last "forever"?

     

    I don't know the answer and, as you say, they can't do any harm.

  4. Turn left at Waters Meet for Worsley and Leigh, and you won't have to go anywhere near the farce, as you call it.

     

    If you want to go to divert to Castlefield on your way to Liverpool, nothing is stopping you, as long as you agree to the possibility of being searched on "closed" days. You wouldn't want to moor in the restricted area at any time.

     

    All in all, pretty much a none restriction, AFAICT, although you are the second person to have a winge about it.

     

    Be sure to wave as you pas The Watch House!

  5. I would be committed for 6 months for a total of around £1200

     

     

    How long did it take you to find a suitable marina? Are you living aboard too? How did you research them, lots of phone calls, visits, or did you just cruise around on the boat till you found somewhere ?

     

    Thanks

     

    We didn't need a residential mooring, but looked at a few boats where their residential mooring was available with the boat, (subject to the owners permission etc. ). We also looked at a variety of marinas all about 30 miles from home. We would have made do with one of these if our ideal mooring hadn't come up immediately.

     

    Our ideal was at our cruising club at Stretford, a mile from home, and it just so happened that a couple of moorings came available at the same time as we bought the boat.

     

    AFAIK most BW marinas have some dedicated residential moorings.

     

    .

  6. And while the experts are about:

     

    I have 110Ah wets which i top up and maintain that have lasted well because they are treated well.... For much the same price i could have 125Ah but sealed.

     

    I am torn, lured by the extra capacity and little maintenance but in my heart feeling a good set of wets and the fact i can maintain them winning out so far.

     

    Thoughts?

     

    +1

  7. Fundamentally my question revolves around "how rare are residential moorings".

     

    I am investigating a live-aboard, trying to collate as much information as I can. Ideally I would want to moor inside a marina as I will need a base in order to travel to work. However, I have found an online mooring in the area where I want to base myself. If this is very rare, then presumably I should snap it up. If its not so rare and finding a mooring will not be a problem, then I can proceed as I am gradually pulling it all together.

     

    I plan to visit as many local marinas as I can to see if I can find somewhere. I have read that its best to turn up in person rather than call.

     

    Thanks for any advice.

     

    I've only been doing this for 8 months, but it seems to me that moorings exactly where you want them, at a reasonable price, are rare, particularly residential.

     

    How long would you be committed for, in the unlikely event that you didn't buy a boat, or found a better mooring? And what would be the cost?

  8.  

    You have an 'intelligent' charger and it is doing 'adaptive' charging and according to Gibbo adaptive charging does not work.

     

    I don't think float necessarily means full.

     

    In your case, as with many others, you are correct.

     

    So..... In some cases float does mean full, (or as good as full). What kind of charger is it when float means as good as full?

     

    My understanding is that whatever the charging regime, we probably need to float for a couple of days to be sure our batteries are full...... Hence the current popularity of "small" solar panels in the absence of a permanent mains supply.

     

    Alternatively, we can turn everything off, let the batteries rest for several hours, (6+ ?), then, if the voltage is above say 12.7V, they are full.

     

    Or we can measure specific gravity.

  9. Yes it means full.

     

    EDIT: see post #5.

     

    Is that:

     

    "Yes it means full" EDIT "No it doesn't mean full" ? :)

     

    After an hour of absorption, when it reverts to float, I can turn my charger off and on, and it will always do another minimum hour of absorption, (i.e. fixed max voltage). I can do this a few times before the Amps drawn by the batteries get down to 7A, whic is about 2% of my 330Ah bank.

     

    I don't think float necessarily means full.

     

    Happy to stand corrected, but the above is how it seems to me?

  10. New one on me.

     

    I suppose you could connect them to a three stage charger and get them to 'float', that way you would know they are fully charged when fitted and any monitoring equipment could be set.

     

    Does float mean full? Or does it mean that particular chargers absorption phase programme has completed?

     

    On my Sterling, absorption is 10 times the bulk period, with a 1 hour minimum, and a 4 hour maximum.

  11. Seems to be working OK. Did a few runs with the batteries pretty well charged. Started at around 40A and then dwindled down until it switched to float voltage. Then I let the batteries discharge to around 12.2V after a few hours rest. Started it up this morning, and it ran at about 70A for about 30 second in the bulk phase, before switching to absorption for an hour, then onto float.

     

    So far so good for £160 and no real hassle.

     

    The question now is.... Do I throw the old module away, or find and fit a couple of caps, or leave it lying around until I decide it's not worth keeping.

  12. Nonsense.

     

    I could get a leisure battery for the price of that book and it should last me at least 3 years.

     

    A great book for boaters. Almost the boaters bible. Worth it's weight in gold, as they say. I think I paid about £40 for mine in 2006.

  13. You need the panel/s, the wire that often comes with the panels, a controller, and a bit more wire to connect the controller to the batteries, and some fuses. Then you need to mount the system.

     

    I bought this for about £186 in an auction:

     

    http://www.ebay.co.uk/itm/100W-LONG-SHAPE-Solar-Charging-Kit-100w-Panel-10A-Charge-Controller-cables/251095968363?ssPageName=WDVW&rd=1&ih=015&category=41981&cmd=ViewItem#ht_7186wt_1002

     

    Haven't fitted it yet - still considering mounting options.

     

    The wires from my controller will be attached the the terminals of my charger inverter, so will be quite short.

     

    If you want a bigger bank, it seems that an expensive MPPT controller may be more appropriate.

     

    We don't live aboard. I wanted something that would finish off the last 10% to 20% of charging while we aren't on board. 2 or 3 amps for a few hours a day for 3 or 4 days can mount up to push in 30-40Ah while we're not there.

  14. I don't live aboard my boat, but I spend a few nights on board each week. In general, when I get on board, the batteries are fully charged showing around 12.7v+. By the time I get up next day, they usually show about 12.3v +/-. This suggests I use about 40% of a 330Ah bank in an evening and a night aboard. Fridge, TV, Speakers, Laptop, iPhone, iPad, 3MiFi. About 130Ah.

     

    About 3 or 4 hours with a generator powering a 70A 3 stage charger seems to get them to the point where they are charging at about 6A, i.e. as good as full.

     

    I'll soon have a 100W solar panel to maintain them while I'm not on board.

     

    If I lived aboard, I'd probably like a bigger bank, so I could go longer between charges, even if I had to charge for longer when the time came.

  15. Written to Sterling quoting Sale of Goods Act 1979..... Fitness for purpose, and last for a reasonable time. We'll see what happens.

     

    RESULT!! I think

     

    Got a call at 9am Tues after emailing the letter at about 11pm Mon. Sterling offered to sell me the "module" for £159.60 inc. VAT and postage. I agreed, even though I could have pushed things further, and it arrived today. Pretty sure I've got a 2 year guarantee on the module.

     

    Fitted it to the unit this evening, and will fit the unit to the boat tomorrow.... Fingers crossed.

     

    A few differences between the original unit and the new one - I wonder if these are improvements?

     

    A difference i can describe is: The capacitors on the original were Jamicon 15000uf 50v. The capacitors on the replacement are RIFA 22000uF 25v. They look soldered on both units.

     

    Another difference is a yellow box type thing replaced by a Song Chuan 30A relay.

  16. It was a refurbished unit with only a 7 day warranty. Sale of Goods Act requires me to prove it was faulty when purchased if it fails after 6 months. I don't fancy my day in court on that one, and im definitely not frightened of a day in court. In this instant i'm leaning towards just letting it leave a sour taste. Having said that, if I can make the time, I might fire off a letter and see how he responds.

     

    I was hoping they would make the honourable offer, but so far they haven't.

     

    Written to Sterling quoting Sale of Goods Act 1979..... Fitness for purpose, and last for a reasonable time. We'll see what happens.

  17. The Victron Centaur has a 3 stage charging profile which seems to have a fixed 4 hour absorption charging time, whereas the Sterling Pro Charge Ultra seems to have a variable absorption charging time.

     

    The variable seems to be preferable as Victron have it in their more expensive Phoenix models.

     

    I've been a Sterling fan for a while, but Victron seems to be a higher quality brand, and I've just had a bad experience with a refurbished Sterling product. New products have a 2 year warranty, so I am leaning towards the Sterling.

     

    Given that I can buy a Centaur 60A or a Pro Charge Ultra 60A for about the same price, £425, is Victron quality preferable to the better charging profile?

     

    I can't justify £600+ for Mastervolt, or for the Victron Phoenix.

     

    NB variable absorbtion charging seems to be where the absorption phase is set at a multiple of the bulk phase, rather than a fixed period.

     

    The answer could be "How long is a piece of string?", or "its the luck of the draw". Searches suggest that some favour one and some the other, and there don't seem to be repeated issues with either brand, but I'd appreciate some up to date thoughts.

     

    Many Thanks
