Ok, so I did ask about 12v. NOT wanting to buy anymore of these ones due to the batteries.
However, I have a small area, which keeps getting holey either by rabbits or stripey foxes, say no more!
I have looked at doing a temporary but permanent fence on 1 strand of wire, but it will double back as a 2nd strand lower down, to keep sheep and cattle in.
At the top of this website there is a link to a fencing company but I read reviews and one of the models I looked at, someone said only lasted a few months.
Amazon sell similar but they too have not brilliant reviews.
So, NOT mains, does anyone have any experience of using a dual powered energiser, like a 9v battery that can also take a 12v in emergencies or similar (solar panel) that would suit my needs? Don't want to have to fork out £150 and it dies within a few months.
I have looked at 9v energisers before and disregarded them yet when I think of how much I spend on my marine batteries (numax) and how they usually die after about 3 years, yet are not used all year round, maybe in the long run, a 9v energiser would work out more cost effective.
A neighbour told me he has a heavy duty solar powered one but the "proper" type of way above my price range.
I have looked at the Hotline Rapters (I think it is) but they are 6v & 12v, so it still means buying another 12v battery.
