Battery fencer life

DJ98

How long do they tend to last(the battery that is) its a b50 fencer also how would you know if it was coming near the end of its life

How long does the battery in a battery fencer last for?

Get a second hand car battery from a scrap dealer. The B20 will work on either 9 or 12v. I bought one last week for €20.

Depends on how many shorts in the wire but a rep told me ten weeks

Sure how could you be lugging that around? Ye must all have quad bikes :-)

Could also be a forcefield b20 and they only work with 9v

Both of the car batteries I got have a swing up plastic handle so no bother to carry around.

It's a forcefield B50

I have one of those and it really depends on how clean the fence is from vegetation. If nothing is touching it and its a short enough span you'll get three months. If its covered in weeds and a long span it could be gone in a week.

The best way is to check with a fence tester and it'll be dropping voltage as it gets close to end of life. So if its 5000v today, 4000v a few days later and less the next test its on the way out.

You could get a 5W solar panel with blocking diode on ebay for around £15, and it would keep it going year round.

The length of the fence shouldn't affect battery life, poor insulators and shorting on vegetation are the big killers.

Ours is donkey years old but has a high and low mode, we usually run it on high for a few days and then dial it back to save battery. Runs of a wee car battery, or used regularly any more but if it were I'd be looking at a solar panel to top up the battery.

I always thought if the manufacturer says the fence is suitable for 4 km fence and you put it on 6 km then it will wear out the battery quicker. Is this wrong?

I wouldn't think so.
If air was a perfect electrical insulator it wouldn't matter but alas it's not and electrical charge can travel through the air and seek out the opposite ions in the air or travel through the air to the ground.

So the longer the fence wire the more of a draw on the fencer.
