Which leisure battery?

Use a block hammer, that should get it in LOL.

They are plastic so should be able to trim them down

Cheers and to Wildebus again. I think it will fit as is but as said, ill measure something tomorrow exactly 3cm and see if it fits in that gap. If so we are on!

the Lead Carbon I linked to and the Xplorer you linked to are essentially the same nominal capacity (130Ah@C100). The Xplorer has a regular usable capacity of around 65Ah. the Lead Carbon will be more like 90Ah usable as you can dischaarge lower without a problem.

That is the reason I went lead carbon plus the massive recharge cycles.

Think there might be a joke in there !
Anyway sounds as though you've won a watch with the new battery

On these battery changeovers, are the posts on top usually the same circumference, just wondering if you have to alter cable clamp fittings?

Hi there are two sizes of the conical battery terminals....the normal size and a smaller japanese size that occurs on a few jap cars. Adapters to fit big connectors onto small jap battery posts are available.
I've only ever seen the small jap posts on small car starter batteries.

Good news, cheers ricc

More and more Leisure Batteries are coming in without post connectiors at all but bolt downs, which need a standard ring terminal (usually 8mm) to connect

Not come across this. I would think it is pretty unusual to encounter? typically you have the +ve and -ve posts which are just about the same size but one (-ve?) is 1mm smaller than the other. I think it is so it is harder to connect the wrong way round but is such a subtle difference, people still manage it

You can now buy adaptor post for the flat terminal batteries on ebay.

I have this agm 120ah that I bought about 12 months ago for a project that I never got around to using
That I probably never will so if any good to you I will let it go for £50 I have kept putting it on charge every 3 months or so, not that it ever needed it
If I remember rightly I think I paid £145 for it

Right. I took some proper measurements and I am as confident as I can be that it will fit so I say we are on!!!

I will send you a private message so that we can discuss details etc. I might even put a shout out on here see if anyone is coming up from your area this week but I suspect not so we will have a drive down and pick it up.

Many thanks.

Put a good lead acid battery in and save your money. Try an EFB. Maybe Yuasa L36 EFB 100AH. More reliable than an AGM, and tons cheaper.

Richard kindly dropped off his unused AGM 120ah battery last night. he got a job up in Scotland so came back via our village to personally drop it of for which I am very grateful. For fifty quid its got to be worth a punt. If its no good for my van ill pass it on to another member for the same price. Vans not here right now as its away getting MOT advisories done but as soon as its back (if it fits) ill get it plugged in and see how it goes.

being an AGM, it doesn't need to be totally flat, so I wonder if you could put it at a bit of an angle and rest it on the frame support on the right hand side? or even make a little platform so it would be level with that support and give you what is maybe 30mm extra width, which might make just the difference you need if tight?

Being a technical expert with an eye for detail I am sure my calculations and measurements will be spot on and it will fit.

When it doesn't, I will resort to a high tech solution to make it fit from my precision high quality motorhome toolkit.

If any of you were wondering why I had not updated the thread, the van is still away (worryingly) at the garage getting MOT advisories looked at. In anticipation of its return and assuming Richards AGM Battery fits does anyone want to take a stab at which setting I should select for it on the Solar MPPT Controller? It mentions an option 5 as user defined but I dont remember seeing that option. The only differences seem to be the floating voltage.

From the manual.

 

[wildebus]

The way to do it is look up the data sheet for the battery to check what the specs are and use option 05 to set the parameters to those two key numbers of Bulk and Float. If you don't have that info available, I would use the Sealed or Gel options.
And to be pedantic, the voltage in the first column is not actually the BULK voltage, it is the Absorption voltage. (Bulk is CC - Constant Current, where the voltage varies, but the current is constant; Absorption is CV - Constant Voltage, where the voltage is constant (and set at the number defined) and the current drops down as the battery gets charged).

Cheers. I'll have a look when the van returns

I guess everyone (that will be no one ) is wondering what happened with the battery change over. Well with the van being away for two weeks getting repaired and then a couple of weeks where we came within a hairs breadth of trading it in this morning we made the decision to keep it for another summer at least so I have gone in this morning to see if I can fit the AGM battery and wahay it fits!! Just.

Seems good. Solar MPPT controller whacked a bit of charge into it but not for long so it must be fully charged. I put some lights on and the satellite dish to see what was going in. At the moment its set to number 2 which is Sealed. I cycled through the options to number 5 which is self defined (custom) but having read the manual it just says "This option is self defined bulk / floating voltage via bundled software". Im pretty sure I saw 14.8v and even 15v going in when I selected this option but I think I also saw 14.8 on option number 2, sealed led acid battery.

Will have a rake around the internet but I am guessing for option 5 it needs plugging into a laptop and some kind of interface to set the parameters. Now I might be a numpty with a screwdriver but I might actually be able to handle this. I wonder if it can be done in situ. Or shall I just leave well alone and leave it on number 2?

 

[barryd]

Left the TV, Satellite and a couple of lights on for four hours last night as a test and straight after the battery was hovering between 12.5 and 12.6 so all is looking good. I think ill maybe just leave the controller as is on number 2.

Certainly is looking good
Unless you definately had the right software (and also the right cable - often it is not just a matter of connecting a simple cable), you'd be best off not fixing what isn't broke Option 2 and 3 look perfectly acceptable I would say (I would typically set the float at a value in-between those two but the difference is not worth loosing sleep over).
