i currently use a 110 amp battery mainly to power my motor mover, maybe twice a year i stay on a field without Ehu, it time to change the battery and i was wondering what benefits if any their would be it i went for a 120 Battery this time ? ....look forward to the help ...cheers
120 amp Leis battery
- Thread starter Fatboy
- Start date
85Ah leisure batteries used to be the "norm" but they don't handle high current as used by motor movers so 110Ah batteries have become the new "norm".
110 vs 120 ?
It'll make no difference to the mover - it'll make no difference when you're on EHU - it'll make no difference off EHU unless you stay longer.
120Ah batteries won't fit all battery boxes.

Measure your battery box & compare the battery sizes
I recently fitted this one & yes it's only 57ahr
hmy: but it moves my van that weighs 1600kg with out a problem, don't be lulled into buying the cheap battery's.... they do not last ...Don't be lulled into paying more to get a better battery - you don't necessarily get what you pay for.Sproket said:RogerL said:

With batteries, you need the right type for the job in hand - and caravanners don't have the same needs despite the superficial similarity.
Until last year, I ALWAYS used sites with EHU apart from a single night en-route to Scotland - for me an old 55Ah car battery was ideal, it smoothed the voltage from the on-board power supply, covered short periods without power and being designed for cars, it handled the high current need by the mover just fine.
For those that do a lot of off-EHU camping, a car battery won't last 5 minutes so a proper deep discharge battery is needed - the problem is that so many so-called "leisure" batteries are actually car batteries with handles!
Personally, I'd avoid a "leisure" battery - use a car battery or a marine battery, dependent on needs.

I have used 2 85Ah batteries over the last 12 years. I have a mover fitted and use it every time I move the van. I have never had a problem despite the fact my current van weighs 1615 Kgs.
I replaced my 110AH with one of these two years ago http://www.tayna.co.uk/Numax-CXV35MF-P8275.html.
The price was about the same so what the heck. Good write ups and the 3 year guarantee.

IMO the Numax CXV range is one of the better leisure/marine batteries available.
I purchased a 135 amp banner battery last year a 4 year warranty and paid around £110 for it.
Had good write ups also

Hi RogerL i have a five year old 85Ah Numax, drives my powrtouch mover and in fact powrtouch advertised a 85Ah will move my 1700kg van. Had no problems with it, never taken it off the van, never charged it during winter, only thing I do is plug the van it at home 2 days before going away.
Must admit that dont use the mover all the time as i can do the reverse thing occasionally
Having said that I purchased one of those c-tek charger thing's last summer from Lidl.... hope I never have to use it

The storage capacity of a battery, Ah, does not directly affect the current output it can provide, just the amount of energy stored. That supply of current is determined principally by the batteries construction details. Some like starter batteries provide high discharge rates whereas deep cycling batteries often can't. You could well have a battery of 85 Ah capacity designed for a high current take off, well able to supply higher current levels than one of very much bigger Ah capacity designed for deeper cycling at low currents.
You can get very small capacity batteries employed in those jump start units that can output current levels to start car engines.
If not requiring a battery well suited for prolonged use off an EHU, then a starter or a marine combined duty battery is suitable, and an 85 Ah will provide enough current for a mover.
But if you require a battery having excellent off EHU capabilities, then it would need to be large to power a mover without in doing so risking self damage.
It is a "horses for courses" game, or it is a compromise, as is the case with recreational boats. There so called "marine" batteries make a half decent job of two very different tasks, starting engines, and providing sustained low drain "hotel loads". They don't excel at either task but are a compromise not to lumber the vessel with two battery types; and to provide a safety back up of being able to start an engine from whatever electrical energy is retained on board.

I have the 110AHr version and its done great. Its done 7 seasons including 7 weeks each year "Off EHU" with a 50 w solar panel. I also use it with a motor mover as I don't believe in reversing the van with the car (worried about clutch problems). I probably will replace it this year as 8 years is probably pushing it too far.
I have always carefully monitored it and never let it get too discharged. I have thought about replacing it with the one you mention, but I think it is just to big to fit.
