Ultracell UCG 100-12 deep cycle battery for sale in Spain.

[Grum]

I decided that our system needed beefing up so bought 2 of the above batteries yesterday. On talking to people they suggested that our solar panel would struggle to charge 3 100ah batteries so I have one going spare. It was €170
Anybody down here in need of a new battery?

Should have said, we are in Cullera for a couple of days then moving southwards.

Ditto as above,keep it.

keep it

5 days are better than 4 at this time of year. Solar pannel will charge 12 months a year big or small.

Basically, what they said was true ........ in the sense that it will take a long, long time for a small panel to fully charge 3 big batteries. They have probably done you a favour in the long run. That is because if you had fitted 3 batteries (deep cycle ones remember?) and run them down to 50% or less, you would soon burn out your onboard battery charger. In fact, depending what type it is, 2 big deep cycle batteries could still burn it out. It will just take a bit longer that's all.

Utter bolocks. If you don't have a clue about a subject, why not keep quiet?

At least I am educated enough to be able to spell bollocks. :lol-049:

Watch it, or you will get banned ..... again. What was your forum name last time? Was it Northerner?

You are just showing yourself up for what you really are. A big mouthed, opinionated, empty headed ******.

deep cycle

Are they wet batteries. ..?
Are they run low batteries? Down to 10% and recharge or 50% as above post?

Hi there hairydog,

I have a Calira 38/20 unit fitted to my van. This unit will charge 200ah of batteries. Not being aware of this I fitted 2 x 110ah leisure batteries so my unit needed to charge 220ah of leisure battery plus the starter battery. I hope you're with me so far. Eventually the Calira couldn't cope and packed up on me. I had a replacement Calira unit fitted, replaced the 2 x 110ah leisure batteries with 1 x 100ah silver Bosch battery and since then have had no problems. Electric and charging systems in Motorhomes are not always as simple as we would like to think.
Now, what I'm telling you is a fact. What I'm telling you supports the comments maingate posted so they're not utter bolocks (or bollocks if you can spell). No need to thank me for the information but maybe you'll want to apologise to someone else eh?

The truth here is that some motorhomer chargers are just a transformer connected to the batteries. These units can deteriorate and ultimately fail if they are used to charge larger battery banks than they are designed for. You will find these units in older vans. Modern vans generally have intelligent multi stage chargers than can charge larger battery bank sizes, although more slowly. I have fitted a new charging system to a couple of vans when installing a Ctek D250S. The D250S has an input for solar / wind / or any other charging source. So connecting a 15v 25A switched mode PSU to this as well as the solar, turns the D250S into a 5 stage on board charger that can charge up to 300Ah of batteries (800Ah with smartpass unit).

Some good information below.

I am into sorting some big electrical problems and found a wealth of information here. It seems to point very strongly in Jim's summing up of the situation. That does not mean other views are not appreciated. There are more links in the post to battery technology.

Grum stated charging with solar but of what wattage,im running 200ah batterys and charging with 2 panels each running at 100ah,my batterys even in winter are getting a we charge and have not dropped below 12.6v and getting up to 12.9/13v mid day.
No every buddy be nice its almost xmas.

Thank you for your threats. I've never had a different username on this forum, nor shall I ever do. You are quite right. People don't like being told they are wrong, especially when they're very wrong indeed. Feel free to enjoy unchallenged ignorance.

If people are wrong then educate them, provide evidence of your opposing opinion. But do it in a civil and non-confrontational manner.

No, he's quite correct.

It is true that in theory battery chargers should not be damaged by a large battery bank because they can only supply a pre-defined maximum current and no more. However with a large battery bank that is in a discharged state the current requirements may be so large that the charger is having to output its maximum current for extended periods far longer than for a single battery which it was probably designed for. So the internal components that normally would be designed to supply the maximum current for a limited time until a single battery terminal voltage starts to rise as it charges and the current subsequently drops reducing the strain on the charger, conversely however the larger bank of batteries would extend the time that the chargers maximum current is drawn thus stressing the charger beyond its thermal design limits. This effect is worse as the battery's age some chargers can cope well with this and other might fail. Solar chargers in general don't dissipate much current and as such are not generally affected by battery bank size or condition although the same thermal arguments could be applied to them under certain conditions IE:full Spanish sun and heavily discharged batteries.
