Connecting car battery to battery fencer

DJ98

How can I connect a car battery up to my battery fencer, buying a new battery for the fencer about every 6 weeks at the moment

cute geoge

Is it a 9 volt battery fencer only ,some types are 9 or 12 volt .I think if is 9 volt only you can not connect a 12 volt battery directly.But you can get a small 9 to 12 voltage adapter .I got one on e bay for a tenner from china .It work with my 9 volt elephant battery fencer perfectly with a car battery there is a previous tread about this here on boards .That is where i got the idea ,so better information if you go searching for that tread

Not all battery fencers can run off a 12v battery... You need to make sure that your one can first. If so, it probably should have been supplied with the leads to connect to a 12v battery.

Am I alone in thinking that the batteries for these fences are getting worse. I have a few battery fences and a force field in particular is impossible to keep batteries in, another french brand seems significantly easier on power. The length of the fence being powered would usually be only one strand and under 200 metres, I'm practically OCD about insulators, proper posts and clearing away anything that may cause earthing as I like to see all fencing done right. The force field usually goes through a battery in less than 6 weeks constant use, I thought they used to last longer than this? At €20 a battery it doesn't be long running into more than beer money.

I thought they used rechargeable batteries, shows how much I know.

I have a Gallager B50 for over 10 years and I jigged it to take a car battery. Had to run made up leads into it. Once it is rated for 12v, you should be OK. You can get the manual for most of them on line now.

Get a 12v battery fencer and the more joules the longer the run. Get a 5Watt diode solar panel...20euros. Get a car/tractor battery....does not need to be in great condition as a car battery that's past it's best ie will only hold a charge for one or two days is no good as a car battery but will be fine on a solar fence and will actually "heal" it'self as it is constantly being trickle charged all day everyday.

I get my car batteries from a scrap dealer for €20. They come straight out of a car so are in good condition. Have 2 and change them over every week religiously.

Get yourself a solar panel and mount it on top of the fencer, have 2 here, the bigger one connected to a 12v car battery, i had to bring it in to recharge it once for the entire grazing season last year. Them small batteries would rob you.

Solar panel fencer is the way to go. Great peace of mind and no hassle for the entire grazing season.

A fencer with a weak battery is as useful as a chocolate teapot, inflatable dart board, ash tray on a motor bike..... you get the drift...

Once cattle start strolling over an elec fence forget about it.

Have 2 of them here. They are a great job. I also have a standard battery one and never use it in favour of the solar ones.

Cheetah, €250, local hardware/agri merchant.
They were €250-275 online so happy to be able to support the local man.

How long of a fence are the solar fencers able to power

Paxkaging says 1km. They are identical to a standard battery fencer but the solar panel trickle charges the battery afaik.

How does the 'shock' of the solar fence compare to the battery or indeed mains fencers ?

The shock is the same as a standard battery as it is still the battery that supplies the power, the solar panel only re-charges the battery.

I have used solar for three years now but after the first winter I bought a deep cycle battery because a standard one was not up to the job, with so little daylight at that time of year to re-charge.

Got my one in the local co-op, cheetah brand, think it was 380 and you supply the 12v battery after that. I'll look up the model number tonight.

Just bought a pel 406, no battery included and no feckin leads for a battery either. €340 I've it rigged up to a 12v aldi/lidl solar panel and an old tractor battery. Fencer can also be plugged into mains.

One acre is very roughly 300m perimeter.So very roughly according to the manfacturers with a clean run... .02joules/1 acre, .05/3 acres, whereas .5 does 20acres. I would take these with a slight pinch of salt, and put in a slight decrease.

Also the more joules the more drain so the bigger solar panel needed. Eg roughly 5w for up to .5 joules and 10 acres, 10w for .5 up to 1J and 30acres etc. But this is just guessing especially with different leaks and veg.

Does the kit above include everything that I need lalababa? I have a fencer and a battery.

Both those examples would do the job. Something to look out for depending where you are based is corrosion on the crocodile clips and attachments over time. If you have the time I would suggest making some kind of box for the battery against the rain etc.

This is what I have for years,battery slides into the box and electric fence screws to the outside.
Battery was wore out before I started 15 yrs ago and still the same battery

Saw that alright, is 6w enough? I got the impression it's just a trickle charger. €29.99 is good value if it works.

Anyone know where I could buy a set of these, would they allow me to connect fencer to car battery?

The above ones are too expensive, have to pay an import fee and delivery, costing over 70 euro, looking for a cheaper set

I just used 2 single wire connectors like these. Tighen the screw to grip onto
the pin sticking down.

They look very like the crocodile clips on aldi/lidl solar panel.

These any good?
