Awl --

I have discovered that some things, like wireless mouses, can take a battery
that appears dead in another device, and run *for months*.

I just took two AA batts out of my mouse, and I have never seen a battery
test so "dead". Replaced them with "normally dead" batteries! Mouse works
fine.

So if you have a battery tester, you can separate batteries by "degrees of
deadness", and still get some use out of them.

fwiw.... carbon footprints, donchaknow....

Oh yeah, I keep all batts in the freezer.

I use rechargeables in my most everything but one wall clock . I would there
too if I had a charger for "C" cells .

I found that AA batteries with a new terminal voltage of ~1.5V crap out in
the kids video game controllers at around 1.2V. I reuse them in my battery
powered radio which I have on all night and get a couple of WEEKS out of a
pair of them before they go into the recycling.

There are adapters that will make an AA battery fit into a C slot:

For clocks (and other very low current applications), though, the use
of rechargeables is probably not cost effective. Rechargeables die of
old age, and by the time you have charged them enough times to cover
the cost, they'll be dead from old age.

Possibly true, but if you have spares for power outages, clocks and
flashlights are good places to store them. I try to recharge them at
the start of each month. In practice it may be 3 months, which is
enough.

I paid a LOT less than that for 2500mA-H Energizer NiMH batteries and
a CHFM1 charger that fits my camera bag.

I have a Logitech rechargeable mouse on my desktop. Uses a cell phone
type battery. After a couple years, it wouldn't hold a charge for even
an hour, and Logitech says not replaceable. Google and the internet said
otherwise, and it's nearly back to new performance.

But... have a wireless mouse for my laptop, runs on 2 AA batteries.
It'll run on the same batteries for over 2 years!

I trust you put them in a well sealed plastic bag so condensation won't
form and create an electrical leakage path which will run them down.

Maha makes great chargers. I use this one.

I've had one AAA battery fail since last winter when I bought this unit. That battery
was subjected to the abuse of cheaper chargers so it was life limited.

Being able to select charge rate keeps you from cooking the battery. I just wish I could
get a 100 ma charge rate for AAA instead of 200 ma which is the lowest available.

Most cheap chargers cook the damn battery and kill it. Great for battery makers though.

My Mickeysoft mouse has had the same AA battery in it for 2 years. I do put the usb key
back in the storage pocket that turns it off when I'm not using my craptop. Still,
counting the times I've left it on, I'm getting great life out of it.

3 weeks is rather fast for self discharge with NIMH.

The new NiMH batteries will drop 20% in a year.

Ive put all the old style in none important applications and have gone
over to "enerloop" type NiMH batteries in everything else

I've still got some Nicd "D" cells that work, that I got probably in 1971.

Years ago, I looked on the Duracell and Energizer web sites. They say
fridge is OK, freezer is not.

There is a wall mounted charger called Re-Nu that is supposed to
recharge AA or AAA alkaline cells. I bought one. It does. If the cells
are badly discharged, they will charge back up and then leak a couple
weeks later.

Some times, it's worth the money to put in new batteries. Like before
a camping trip, or working up a ladder where it's not convenient to
come down for more batteries. I remember the one time I was on third
floor of a building with no elevator. Walkie talkie batteries went
dead. I got to hoof down three very tall flight of stairs for new
cells. I learned to carry a change of new alkalines in my coat pocket.
