Electrocuting snails.

I want to deter snails from my beans,
Last year I tried copper strips around box, limited success.
So I thought this year I could try putting a small charge through the strips, just enough to make the pesky blighters go away,
I have various Ni-MH batteries, from 2600 mAh through 1300 mAh to 600mAh,
I also have various solar panels, unknown spec, Perhaps I need new.
I guess there would be NO or VERY LITTLE discharge overnight, so it may be just a case of keeping the batteries topped up,
Would I need a dummy load say a LED, what if a short circuit accurred?
Could I just put a diode in circuit to avoid discharge in the day?

Why a second thread?

Sorry
started asking one question, and ended up wanting answere from another.
I'm sure you can help me

Baz,
Please try and keep related subjects together, otherwise it can get very confusing when split over several threads.

I will now close this thread.
