Hello... I am storing a few rechargable whipper snipper batteries in my
garden shed along with other assorted batteries. I want to time my charger
to give them a charge say 1 day every two months or maybe one day a month. I
know if I go out to the shed and just plug the battery charger in I'll
freaking forget about them and they'll charge for a freaking week before I
remember. (I'm 51 and my mind is toast...70"s were real good to me lol)
Anyways...I googled "monthly timer" etc and found nothing that would
help... is there a 110 volt timer that will do something like this? If you
run across this would you mind posting a link? Thanks folks.. Jim

A bunch of timers he http://tinyurl.com/28zfyee
I didn't try to sort through them. The link is to Allied Electronics.
I don't think they sell retail but at least you'll get an idea if what
you want is available.
