Anybody else have a problem with batteries leaking inside flashlights, particularly metal ones like Maglite? Whether it be a AAA, AA or D cell they get ruined by the acid and the batteries won't come out. My old faithful plastic flashlights off the tool truck years ago don't seem to have the issue. Do the metal flashlights have a reaction over time with batteries causing this or do I have bad luck with batteries? :dunno:

I have a Maglight that had a battery start to corrode in it. I took the lens / bulb out and filled the barrel of the flashlight with WD-40, then just let it sit for a week. I was able to save it.

Death, taxes and battery corrosion.... they are all pretty much inevitable.

It can happen in metal and plastic, the batteries don't care what they are surrounded with. :) If you can loosen a tail cap so he light won't come on meaning the circuit is open, it would help keep this from happening. If you really want to keep it from happening on AAA and AA at least, use lithium batteries since they won't leak like alkalines. Or switch to rechargeables since they won't leak either.

Maglites are notorious for being hardly bigger than the battery, so any swelling of the battery and they get stuck.

I had a 2 D Maglite that the batteries went bad in and couldn't even unscrew the bottom to get them out. Destroyed it trying to get it apart, mounted in a vice with a pipe wrench on the end - it was like I welded the end cap on.

didn't most battery companies used to guarantee their batteries against leaking? I remember sending some thing back to them and they paid replacement price for what was ruined.

I was just having the battery leaking problem conversation with my wife this AM. I went years with no problems at all. However in the past 2 or so years there have been a lot more leaking batteries. Good brands too. Duracell, Rayovac, Energizer. Have there been any manufacturing changes or COO changes? Seems weird.

I Just had this happen to a two battery, LED, AA Maglite. I soaked it in Kroil and had to use a nut driver that was just big enough to not touch the LED chip, and I had to pound it out with a hammer because on the LED model the LED assembly goes in from the bottom. I had nothing to loose or I would not have used a hammer. I was amazed after I was done cleaning it up that it still worked. I am going to try some Lithium batteries as mentioned above as I don't want to have this problem again.

I had the exact same problem.

I've pretty much given up on regular alkalines for flashlights and use Eneloops. The only one that doesn't have an Eneloop in it is my little Streamlight Microstream, because I always lose the damned AAA Eneloops.

Had a maglight do that to me once. I got the cap off, tapped the back against a piece of wood for ages until the battery came out.

EverReady brand batteries had a policy of replacing any flashlights that their brand batteries leaked into and destroyed. I'm not sure if that deal still applies.

Just about all name brand battery companies will repair or replace any item damaged by their leaking batteries, however you have to send it to them as is...like don't try taking the batteries out or cleaning it yourself. It's alkaline so an acidic solution like vinegar sometimes helps.

I have had very good luck with my Panasonic Eneloops. These are the real deal rechargeables. Once you go Eneloop you can't go back. I run the white ones but they also make Eneloop Pro in black packaging which are also real good.

I had bad luck with any other brands beside duracell and energizer. Ruined a maglight and a gerber light using rayovacs.

Its become more common with the rise of Chinese LEDs since most come with some China junk batteries in them that rupture within a year like clockwork. Really cant say I've had a problem with Duracell or Energizer although both do make some stuff in China as well (mainly small cell).

I have only had things ruined by corrosion from batteries bring unused and sitting for long periods of time this includes remotes and flashlights and anything battery powered aswell

Agreed. Last few I had were hardly used flashlights.

Ive taken to not leaving batteries in them and keeping them beside them.

Yes I have had about 3 different MAG-Lites where the Duracell batteries leaked in them and could not get them out. I contacted Duracell and they asked me to ship them the flashlight and I received a brand new replacement in the mail.. They even paid for shipping.

Maglites plus alkaline batteries equal disaster - especially in hot temps. It's why I left Maglite for Eveready constuction-grade plastic flashlights until the LED conversion kits became affordable. Then, I could use old carbon/zinc batteries (and get decent light outpu) and avoid the caustic electrolyte leakage.

I experienced my first battery leakdown in a flashlight this past february. Guess luck has been on my side all this time. It killed a Rayovac Indestructable AA flashlight. Batteries where Duracells (my preferred battery, still is).

I called up the Duracell customer service number and they provided me with a coupon for a free pack of batteries (max 24 count), and they sent me a cheque to cover the cost of the flashlight.

Two thumbs up to duracell for a no hassle experience. And the lady I was talking to was in Wisconsin. Bonus was, I could understand every word she said and didn't need to say 'what?' every third word to hear it, or figure out what she was actually saying. They asked the typical what happened, how I store and use my flashlight and asked for the date code on the battery and the location it was printed (I was able to extract one battery). the rest was filled in with friendly banter about where the call center was located, batteries in general, weather, and other small talk. They did not request return of the flashlight. Maybe due to being in Canada, or the date code on my battery was enough to confirm it was part of a known bad batch. Overall, I got to hand it to Duracell for how they handle this sort of situation.

The Amazon Basics brand rechargeable batteries are supposedly the same OEM and quite a bit cheaper. There's a prominent reviewer on Amazon with a very convincing argument. He's careful to acknowledge they may not be the same, but his testing shows very good performance from the Amazon batteries nonetheless.

In anything critical I use energizer lithium batteries. Around the house I use eneloops in just about everything except for my D cell Maglight, that uses Duracell pro alkali es. No issues so far...

I've had radios, flashlights, clocks damaged by duracell and energizer from AAA all the way to D cells. I no longer keep alkaline's installed in long term storage items. I try to only buy things that use AA or AAA and use energizer lithium now. Especially for the flashlight in the car. Every once in a while Sam's club has a sale on them I think it's about $15 for a pack of 16.

I've had several AA and AAA Maglites corrode from Kirkland batteries but not with Duracells. I just dump the flashlight and buy another.

Another vote here for Eneloops. They require a little initial investment, but pay for themselves after recharging a few times.

No matter the major brand, I've had them all leak to varying degrees, damaging or outright destroying things from flashlights, remotes, test equipment, you name it. For AA, AAA and 9 volt applications, I will use lithium primary cells (Energizer Advanced or Ultimate brand) for items that get intermittent use yet still need to be ready for immediate use. For things like radios, electronics and other stuff that gets regular use, I use Eneloop or similar low self-discharge NiMH cells which are far less prone to sudden leakage, but aren't immune. Then there are some items that don't like the slightly lower voltage of the NiMH cells, so those tend to get regular alkalines. There simply isn't any sure way to predict if a battery will leak, in most of my cases, the battery is still putting out decent voltage when it began to leak, these aren't batteries that have long died and were forgotten. I tossed out over a dozen fairly new Duracell Quantum AA cells that I had put into the smoke detectors not long ago, one began chirping the low battery warning in about 5 months, when I checked, one of the three cells had begun leaking badly. I checked all the detectors, and found another cell leaking. Rather than risking damage, I replaced all the cells with a different brand.

I have an ancient Canon pocket calculator i used in middle and high school, it now resides in my basement workshop toolbox. It still has the same two steel-clad Duracells I put in the calculator sometime around 1980-82. They are still going strong. So is that old calculator. It gets used on average once a month or so. Those batteries might outlast me.

I had the same thing happen to one of my MagLites in high school. I forgot all about it.

I know I still have it. Since it's destroyed anyway...maybe my hydraulic press can get them out...:bounce:

Mag lights , many flashlights and tools that used batteries.
Mag lights corrode inside and no way to take it out even with a drift punch and hammer. The the tools are just the alkaline leaked and corrode the springs on the battery holder so bad that it is no longer use-able... now I just try to take out all the batteries when ever I have tools I am not using all the time.

^^ this. I was surprised recently to find a missing flashlight that I had not seen in 2 years and batteries, although dead, were intact.

The issue here isn't the type of light, or how long the bstteries are in it, or even whether it's used or not! It's simply down to the quality of the batteries!

There was a time, when Duracell batteries were only made in the U.S.A. and Europe, that they were guaranteed not to leak! Now that they are made anywhere and everywhere that guarantee seems to have been withdrawn!

Things are not helped by many of the light makers, or perhaps I should say importers! Having had the light made and packed in China, they include ****** Chinese duracells, or whatever, in the pack! I recently bought 2 Olight O-pen's, and foolishly installed the supplied batteries. They leaked in the first light in about 4 months, trashing an otherwise decent light, and even leaked in the packing with the second, as I hadn't installed them!

The solution is to use decent batteries. Decent rechargeables are one option, but they don't suit everyone, especially if something is used infrequently, but you need it to work when you do (such as most flashlights)!

The best batteries I've found are Panasonic Pro Plus. I have been using them for well over 10 years and have NEVER had a leaky one! I have experienced leaks with both Duracell and Energizer, so avoid them, even if made somewhere decent as even these don't seem to be as good as they were!

Using anything Chinese is inviting trouble!

i've adopted the idea of removing batteries from whatever is not used daily.
the last time batteries leaked on me ruined a $400 meter. ray-o-vac stood up behind their warranty and re imbursed me.
recently I was given several 'vintage' sentimental meters. the original owner left the batteries in. so old, no dates on batteries. meters ruined.

As far as I can tell, the batteries discharge before they leak and ruin the device.

I have had multiple battery brands send me refund checks for wasted mag-lites. They are picky about the battery date codes, though.

The answer is to GET RID OF WEAK BATTERIES, and don't let any of them go past the expiration date.

In my experience Duracells are about the worst at leaking. I've taken to removing the batteries from any device that doesn't get used regularly (flashlights, laser measuring tools, etc) and storing the gadget together with loose batteries in a zip-loc bag.

It is hard to believe that with today's technology they can't make an alkaline type battery that will never leak. If everyone who had a ruined device due to leakage sent it in to make a warranty claim the manufacturers would probably improve their products (or eliminate the warranty) but most people just trash and replace.
