I have 4 of these (see attached photo), and I’ve just fitted 4 x 100 watt panels on the roof. Now the electrical part. The Solar controller has 4 options. Sealed, GEL, flooded and Li (see attached photo).
I already have installed a Victron Smart Shunt and Victron B2B, 30 amp.
I know my batteries are not GEL or Li.
But can not find on the Yuasa battery website, or anywhere else, just what they are.
I’d venture sealed, but if someone could tell me categorically, it would be much appreciated, it’s due to be up and running in the morning.

Might you need to set the charging profile on the B2B once you know the battery type.
 
I was speaking to technical help at Ecobat (who make Numax batteries) the other day about identifying my leisure batteries which are confusingly described across various websites as "sealed", "flooded" or "sealed wet". Apparently all these names mean the same thing. It's a lead acid battery.

I would strongly suspect yours is a lead acid battery also.

The label says it’s is class C, which is a category of battery invented by the NCC. Class C is for low capacity light use.

p.s. The NCC are not an organisation I take much notice of, they are an industry body not a consumer one.

NCC Battery classification is total BS and best ignored.
 
So sealed or flooded? It has top up caps, as donkey has said. So that leaves flooded.
But Sandancers says that flooded, sealed and sealed wet all mean the same thing!!
And rb62 says acid, which isn’t even one of the 4 options that are on the controller.
Does this really only leave flooded as the feasible answer?

That is a very good point. Nothing comes up as a sealed or flooded option on the Victron b2b. A battery retailer, Tayna, where I purchased my batteries, told me to use the preset “Gel Victron deep discharge” with the attached parameters. Does this look right to you? You’ve worried me now!

Thank you for inviting me to comment...however I know that different charging profiles are available on the B2B having set my Lithium up. But believe me there are more qualified and experienced folk on here that can offer a more accurate answer...

Well I hope someone answers!
The words lead, sealed, acid or indeed sealed are not shown anywhere on the ready made profiles on the Victron b2b
 
They are flooded and that is the setting you should put it on with your current set-up…. However, I would change the batteries to a couple of gels to make the most of your investment, and of course if you can stretch to lithium then even better but then you may have to alter your vans charging system… but with the solar and B2B and get bang for your buck I would buy at least 2 gels….😎
 
Just noticed you have 4 batteries now, they must be heavy and eating into your payload, 2 exide gels will probably give you just as much power you’ll get from the 4 leads and will halve the weight…😎

I’m no expert by any means but the b2b on gel profile could cook your present lead batteries… 😎

Might also get gassing. They appear to have a recommended charge rate of only 4A.
 
Why not simply take a couple of the filling caps off to see if they are full of water? (My money is on yes) then you know for sure they are flooded lead acid. At the same time you can check and top up all the cells and set your charging system to suit👍😉
 
Bearing in mind all the most helpful of comments on this thread. Not one as yet been able to categorically say what type of battery it is. Although it is from a main supplier that has loads of technical info about the battery, on the battery, and more on the website. All which means very little to me.
If anyone can come up with an answer this morning before I attach the solar controller it would be much appreciated.
Looking at my first post, we have got it down to flooded or sealed. But it has “vent” holes, so probably flooded. BUT is it definitely flooded?
 
If I had four lead acid batteries and there was nothing wrong with them I would be intent on using them and getting my money's worth out of them - not going and buying a couple of gel batteries that would probably be quite expensive.

Yes, it says it's vented on the data sheet so it is a flooded battery, beware of using the gel setting because gel batteries need an extended absorption phase which may cook your flooded ones, also be aware that the ideal charge rate is 4 ah so they may take a fair while to recharge. To me these look like dual purpose batteries and are not really best suited for leisure use.
 
Think the charging profiles are the same for flooded or sealed so it doesn't matter

The Yuasa tech details say it must be vented which says to me wet lead acid. It would probably say if it was AGM or Gel. However it also says maintenance free which would suggest sealed/VRLA. I hesitate to give a definitive answer because Yuasa don’t and sealed and flooded are not mutually exclusive definitions when some are VRLA. You could ask Yuasa.
 
Our Numax batteries are "sealed", but if you take the top sticky label off they have plugs exactly the same as a "flooded" battery which you can remove to check liquid level. They need a vent pipe the same as a flooded cell, so to me there is no difference.

Thanks for all the comments everyone. It would seem that it’d be best to get gel batteries. But, I have 4 perfectly good batteries that are sold as Leisure. And if anyone knows what settings would be right for the Victron b2b 30amp, that would held loads (geddit)
 
Your set up with your batteries with the solar and controller set to flooded are fine, it’s the b2b that changes it. Perhaps don’t connect the b2b just yet and see how you get on. I have 400w solar and two gels, I have more then enough power for my needs even on a very dull day, I don’t have a b2b…😎

Raul may be the best person to advise you, but as a starting point I would set absorption voltage to 14.4v float voltage to 13.2v turn adaptive absorption time on and max absorption time to 2hrs.

Have you tried looking for a phone number for Victron technical help ? Bet they could advise you best of all.
 
They're just an entry level lead acid, so use that charging profile. You have 72 kg of batteries which take up a fair amount od space that have 140Ah of usable power (50% of actual Ah).

Now you have them you might as well get your moneys worth out of them, but when they die I'd be getting (depending on power requirement and budget) - Lithium, Gel (and there's a new variant lead carbon gel which has good specs). Even the Yuasa L36 EFB would be better as it's sealed.
