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
So leaving the batteries hooked up to the charger will harm them? Do you
have some documentation saying this? This isn't the case for my Hitachi
drill or my Black and decker Weed Hog trimmer. Most NiMH/NiCAD chargers
are somewhat more smart than just a wall wart. If you haven't read about
charging these I suggest you do so. I'm in my mid 50's and the 70's were
REAL good to me also :) but evidently I didn't fry enough brain cells to
affect my short term memory.
I see. Are you trying to save a few watts of electricity, afraid the
chargers will catch fire, trying to extend the life of the charges, all
of the above or have some other logical reason that you want the charges
off immediately after use? You have a computer obviously. There are free
programs that can remind you of certain events that you could set up
to remind you to turn the chargers off. Can you have a neighbor remind
you? A relative? Friend? Hell gimme your phone number and I'll call you
and remind you.
Why in hell are you so curious as to WHY I want to do what I want to
do?... It was a simple question that obviously you have no answer to and
have contributed NOTHING!....so why not just shut the hell up?.. Are you
truly drunk when you drivel on like this? Jim
Because often times the WHY is very relevant. It's often based on some
old wives' tale, or irrational paranoid delusions.
If you have some practical technical reason then it might be worth our
time to spend some time helping you find your answer. However, if
you're just another net.kook who can't be convinced that he doesn't
really need to wear that tinfoil hat, then there's no sense in wasting
any more time on you.
Frankly, I'm starting to lean towards the latter choice.
Decent chargers won't overcharge batteries but if this is cheap crap,
you could just put them on a timer and charge them an hour a day.
Your bigger worry is storing the batteries outside in the shed.
Depending on where you live, that'll cook 'em just as sure as
Just get a mechanical twist timer. As you walk by once in a while, give it a
twist. The chargers will run for an hour or whatever you set it to, then turn
off. You can probably get one that will go up to 24 hours if you need.
You could use a sprinkler timer switching a relay to the power.
That's just replacing the burden of remembering one thing with
remembering something else. His problem is remembering, period. Net
Here is a solution:
Hook any old daily timer to a MECHANICAL 7-day timers in series.
Program the daily to run 6 hours a day. Program the 7-day timer to run
one hour a week.
End result will be one hour of power every 4 weeks.
There are wall switches with a weekly timer. You can have it turn on
an outlet for 10 minutes a week.
You can also use standard mechanical timers. Have it turn on for one
hour every 24 hours and when it is on have it power another such timer
that will turn on for one hour of every 24 hours of elapsed time, and
run the charger off of that.
So the first timer will run all the time, and the second timer will
take 24 days to cover 24 hours. So the charger will be on one hour
every 24 days.
Thanks. I thought about this some more and though I was right, it
will be on one hour every 24 days, the hour will probably be split
over two consecutive days. Like 25 minutes one day and 35 the next.
Probably won't matter when charging a battery but might in some ways
if one is taking time lapse photography or something.
A bunch of timers here: 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.
There are plenty of timers that you can schedule for a week, choosing the
days you want it to go on. Use one of those and have it come on for a half
hour a week instead of 2 hours a month.
