How do you dispose of your alkaline batteries? It's against the law to
just throw them into the trash here in California.
 
I have a lot of Eveready rechargable batteries and the proper Eveready
battery gizmo recharger here.I am too lazy to fool around with that
stuff all the time, unlless a long power outage occurs.I can use one of
my inverters and charge those batteries up from one of my van batteries
if I need to.

Which goes counter to what the trash is for, too...

Then again, it's California, where *everything* has been shown to
cause cancer and must have a warning.
Nah, we just don't like to pollute our ground water.

I am trying not to rely on Hybrio's supposed long-storage life, and to
carry a spare set of cells at all times.
Wouldn't you know it? Just two days after I wrote that I got caught
out.

On Saturday, I took my camera and flash to a family gathering.
Because I knew the Hybrios in the flash had been there for several
months, and had been used for many dozens of flashes, I took a spare
set too. Sure enough, after ten or twelve flashes, the flash
recycling time became significant. Out with the old, in with the new.
One flash, flash dead - no recharge action at all.

Unfortunately, I hadn't packed my mini digital meter, and there's only
so much swapping of cells one can manage in an effort to find 4
vaguely-usable cells from a set of eight that must include at least
two completely flat cells.

Testing once back home showed one cell of the eight was really poor,
presumably one from the reserve set. Four more were in the
well-discharged area (but not absolutely empty), and three were low.
A "best" set of 4 gave only another dozen manual flashes.

So now I need to add "check all cell voltages in the spare set before
taking it out for use". Plus I'm being more careful about identifying
cells which aren't taking or keeping as much charge as their
set-mates. None of which will bring back the missed opportunities of
Saturday.

I'll carry on using the Hybrios, if only because they do seem to hold
part-charge better than standard NiMH, but I won't buy any more.

Try one of the dozen or so alternative brands. I've has GREAT success
with the Kodak LSD cells and the Sanyo Eneloop LSD cells.

I've learned from experience to take a big pile o' freshly recharged
batteries when I go out to photograph. One advantage of this is that I can
leave the flash on all the time, not having to switch it on and off as I
take pictures.

Indeed - which makes the self discharge rate pretty irrelevant. Especially
as even Ni-Cads aren't that bad.

Have just bought the latest type of rechargeable *Hybrid* batteries from
Maplin, made by Uniross, called Hybrio. (also Argos are now selling them
made by Sanyo).

They are supposed to have the advantage over Nickel Metal Hydride in that
they don't have the 'memory effect'. Also the advantage of the Alkaline,
in
that they dont self discharge at quite a high rate when not being used.

The charger I have is an Energiser designed for Nickel Hydride batteries
and
which indicates when a battery is fully charged, by the charging light
going
off. But when putting in the Hybrid batteries the light does not go off.

Is there an harm done to these hybrid batteries if they are overcharged?


Would it be to much trouble to identify the specific charger?
Many thanks to all. (except possibly Mr *Moody* Sommerwerck) The charger
is Energizer, Model; 'Compact Charger' (no serial numbers on it).

A big killer of nickel cells is internal salts. They allow electrical
leakage so a cell won't hold a charge long and eventually can't be
charged at all. These deposits increase during trickle or C/10 charging
but apparently not with fast charging.

There are ways to burn off those salts. I suppose it might be done
with a well designed apparatus to gain a bit more life from a dead
cell, but not economically practical. For emergency purposes or as an
experiment, one can "tickle" the cell with a high voltage. I have even
used 120VAC from the wall socket. This is not for the feint of heart
and I would not advise even experimenting without proper eye and other
protection. A 12VDC battery applied to a 1.5VDC cell might be held
for about a second and no more.
In 1982, first time I saw self-discharge progress to a full short, I
zapped it with a capacitor charged to 170 V. It would take a charge
after that, but self-discharge was still high. I decided fixing shorted
NiCads wasn't worth much.
