I usually use Duracell or Energizer batteries. I got some Rayovac
batteries because they were cheaper. I figured that they were about
the same, and you are paying for Duracell and Energizer advertising. I
had the Rayovac batteries in two Maglite flashlights. Both started
getting dim, so I opened them up to change the batteries. The Rayovac
batteries had leaked and ruined the flashlights. I contacted Rayovac
- they said that they were reimbursing me for the flashlights and
today I received new batteries from them.
I'm afraid to use the replacement Rayovac batteries - they might leak
and ruin something else. Do Rayovac batteries have problems with
I suppose any cell will leak if sufficiently abused.
Personally, I buy cheap alkalines at discount places for about $.25/cell.
Occasionally I find signs of slight "leakage" in stuff that I left the
batteries in but didn't use.
Most severe leakage usually comes when you leave something on and the cells
are completely drained. When this happens, one cell is likely to end up
being discharged to the point where it exhibits polarity reversal. Now
THAT'S when you get serious leakage.
IOW: your best protection against leakage is: 1) only use alkaline cells
in disposable applications; 2) don't leave the gadget turned on; and 3) when
you KNOW the battteries are "weak" just toss them.
Keep plenty of spare cells around so that you aren't tempted to leave "weak"
cells inside appliances where they can cause problems.
Personally, I use a mix of NiCads, MNiH, and alkalines. Heavy drawing
stuff uses rechargables. Otherwise, I use AA & AAA alkalines.
We had several MagLites over the years, all but one of them gifts.
Each and every one was destroyed by leaking batteries. All the batteries
used were either Energizer or Duracell alkaline.
I have come to the tentative conclusion that the primary issue is that
MagLites are sealed too well to allow any sort of air flow through them.
Our other less-well-sealed flashlights (some dating back to the '80s) do
not suffer from this problem, even with the same brand and type of
batteries. This is what leads me to the tentative conclusion mentioned
My solution: unload the MagLite when not in use; leave it open; only
install the batteries when you need the flashlight.
IMO a flashlight without batteries in it is useless.
Always want it fast, and ready.
I've got at least 3 Maglites and never had a battery leak in them.
I never use Ray-O-Vac, which I've had leak long ago.
Never had Duracells leak.
Usually there's cheap batteries in them that my wife picks up at Big
Lots or some other bargain place.
I looked at the Mags in the kitchen and the 5-cell has Fuji something
in it, the 3-cell was empty.
Since I picked up a few packs of those HF LED flashlights I hardly use
the MagLites anyway.
Grabbed the empty Maglite just the other day and when I saw it didn't
light I just grabbed one of the LED's, which filled the bill.
Got those little things all around the house.
Anybody using Eneloops?
I've been using them for all my wireless stuff and digital camera for
about a year now and really like them. They hold a charge longer than
the Targa and Ever-Ready rechargeables I was using before, and don't
degrade after repeated chargings like those did.
That's just my impression, no scientific testing.
I'm thinking about getting some more for the flashlights, and have
just one battery type in the house.
I'll tell my wife not to buy any more batteries, and just go see the
Master of Batteries - me - for any battery needs.
No inappropriate jokes here - please.
But Eneloops are a bit more expensive than most rechargeables, so I
haven't pulled the trigger on that.
Pretty much. Who wants to fumble in the dark looking for batteries or
loading them into unit when the lights go out? I've found that if any
device is left on, they can cause the alkaline cells to leak. I've had them
ALL leak - Rayovacs, Energizers and even Duracells. The only exceptions are
NiMH, which I've never had leak under any circumstances.
I've been testing them for the last year. Very useful in high drain stuff
like portable TV's, cameras, etc. Seem to hold a charge for at least six
months - I've got a digital charger that tells you how many mA's of charge a
battery takes so in about six months from now I'll know how well they hold a
charge over a year. I charged a batch up that I bought this summer and just
put them away. Package claims 80% charge retention - we'll see.
While they are pricey, it does seem that will be very useful in LED
flashlights because of the long charge retention. Using NiMH cells in
flashlights usually means recharging them every 3 months to make sure they
still work and that's a PITA. So is going for a flashlight and finding it
ruined from a battery leak.

I don't know about them but I've had good results using Tenergy
batteries - I get them through www.all-battery.com. I have no
financial or other connection with them except that I like the
I commute by bike through much of the winter, so I use their batteries
in lots of lights as well as my heated gloves. I also use them in all
the remotes in the house. They last for a few years, with heavy use in
the winter months and fairly light use otherwise. I also use their
batteries for my two Roombas.

The springs on some of the Maglites are very strong - strong enough to
make it hard to get it on in the dark.
In both of my cases, it was not the battery near the cap that was
leaking (or not leaking the most). I was able to get the first
battery out, but the second one was frozen in there.
As far as getting the flashlight on quickly (in another message), some
people in this family are stressed when the lights go out, so it is
important to get them on quickly.
I never thought of that before.
Perhaps the spring is strong enough that it can compromise the seals on the
batteries. You wouldn't necessarily see the leaks from the battery nearest
the spring, but from the one(s) which had the weakest sealing in the first
Oddly, I seem to have been presented with a lot of kids' toys lately to
fix that I was unable to do so because of leaking batteries. They were
all rayovacs. I just dug out some old wireless mice that'd been in a
drawer for months, unused - no leakage. Batteries in one were Energizer
and the other Duracell. I can't remember the last time I had a leakage
problem, but I never use Rayovac batteries - mostly use Energizer
lithium when I can find them because I hate having to buy batteries.
Also have several LED flashlights with the Duracell batteries that they
came with still in them, some of them more than a year old.
completely anecdotal, I know, but I can't remember the last time I saw a
battery that had leaked that *wasn't* a Rayovac.
replace "roosters" with "cox" to reply.
That has been my recent experience too, but as you say, that is only
Rayovac sent me two sets of replacements. I'm afraid to use them,
except I may use them for a while and get rid of them before they have
a chance to leak.
I've used Rayovac AA's for 20 or so years and don't recall having a
problem. I normally wait for the sales and about a month ago bought 30
of them for about 35 cents a piece. My main application long ago was in
electronics in pinball machines, used to hold the memory when turned off
(yes old technology). I'd use a couple hundred a year. They go through
a lot of heat, which most batteries don't like but they seemed to be
just as good as the name brands spending millions of $$ in TV commercials.
I can't say they never leaked, but when things get left go for 5 or more
years, the name brand ones leaked also.

Last week I tossed the second Mag Lite (3 D cell) flashlight that Rayovac
batteries ruined. This time was a repeat of the first time, the center cell
went bad and leaked and swelled - sort of welded to the flashlight body. Like
the first time, slamming the tube on the top of my workbench eventually freed
the battery but the switch shifts in the process and flashlight was ruined.
Having to pop for another MagLite pissed me off.
If it was just the 2 flashlights (about 10 years apart) I probably wouldn't be
taking the time to even write this note, but during that time frame there were
other Rayovac leaks - the LED light set, the camera, and the rec room remote
control, and the battery organizer. All had Rayovacs (but at least for those
the damage was not beyond repair and I was able to remove the batteries in those
and clean the equipment up). However, I'm fed up with having to spend my time
to fix problems caused by leaky Rayovac batteries and having to spend money to
replace Mag Lites. Plus I have a bunch of the batteries that I now afraid to
I don't have receipts but I'm disgusted enough that sent a note to Rayovac -
we'll see what they say/do.
