I had removed the batteries from electronics that do not get used often, but a flashlight escaped. :oops:
The battery had corroded, but the flashlight still works. :tu:
Check your stuff, and remove batteries from them and store them separately if you don't use them often.

Important tip if you use non-rechargable alkaline batteries. :tu:
(Why do they poo in your electronics so much? :rant: it happened to me, and annoyed me enough to throw them all away for a better replacement chemistry)
-
I'll still use alkaline disposables for the lights that I don't care about, but all my good ones get eneloop or lithium rechargeable batteries for this reason right here.

All my good lights have rechargables but I need to go and check all the rest to make sure they don't corrode :ahhh

Good heads up reminder :cheers:

Only Eneloops for me.

My new goto for long term storage batteries is Energizer Ultimate Lithium AAs and AAAs. Pricey, but extremely good run times and 15+ year shelf life.
I have a set of 2xAAA Ultimate Lithiums in my work light and it has so far outlasted a set of regular alkaline batteries by 5x.
My digital camera can take 20 photos with a new set of quality alkaline batteries, but the Ultimate Lithiums can take 250 photos in the same camera. Then the ULs are still good for using in flashlights stowed away for over 10 years.

I agree,
Energizer L91 Lithium (AA) and L92 (AAA) are excellent "disposable" batteries,
They do not lose acid, have high autonomy, weigh little and do not fear frost,
They can also allow powerful AA lights like Armytek or Zebralight to emit full power.
-
I don't trust anything, I lost a ThruNite T10s flashlight to an Eneloop that spilled its guts inside it. :cry:
If you wanna store it for a longer time, lithium or lithium ion from reputable brands. Otherwise, store separatly
-
I always try and remove the batteries from stuff that doesn’t get used much
But I have forgotten before as well and it makes a real mess of things :ahhh
-
I use a lot of AA batteries and they are still a staple of my EDC really and I use Leakers all the time but I use them fast and get rid of the bodies too!
Using them like this has kept them from getting a chance to blow on me so far and I have no intention of changing things up as long as I remain diligent about keeping the fresh ones in the light.
My SC52 and LD12 might go through a few sets a day on some days and they never get the chance to leak.
Otherwise for lights that I do not use every day and all day long I use L91 or Eneloop pr Lithium 14500s to avoid the pain of the leak.

:cheers: to lithium fans. It is a wonder element indeed.
Used for antipsychotic medications, awesome batteries, and many other things. :woohoo:

Kinda surprised Eneloops leaking :-[. I've had some Eneloops sitting in lights for a while with no issues. I also make sure to unscrew the heads slightly so no accidental activation while sitting. Thanks for the heads up tho, Ill keep an eye on those lights.
I have Surefire Lithium and Panasonic as well as Olight 14500s rechargeable. I run the 14500s in my Zebralight SC52L2.

Me too, except appliances that I use daily(like my mouse), pretty much everything else that use AA or AAA are all L91 for me.
I have the habit of keeping some of the lights with batteries, so that I can pick up and play/use. But way too many times I have lost lights/appliances due to leaky batteries, either alkaline or even eneloop might leak over time. So basically I am going all lithium for everything I used. The longer battery life/no leak kinda pay for itself.

Interesting. I've never had an eneloop leak.

Using a non-technical subjective comparison.
I did the subjective math on Energizer Lithium ultimate batteries in my digital camera. An 8 pack of Energizer Lithium Ultimates is $9.99(so $1.25ea basically) locally. Alkaline cheapies are an 8 pack for $1.99($0.25ea basically). My digital camera can take an average of 20 photos on a pair of cheap alkalines($0.50 basically). And the Lithium batteries in the camera can take 200 photos on average with a pair of Lithiums($2.50 basically). So the Lithium batteries work at 10x the operating capacity in the camera and cost just 5x the price. The Lithiums cost me 1/2 the cost of the alkalines in the long run. Now, that said, those figures don't reflect operation in other devices. They also don't account for damage costs from alkaline leakage or shelf life if the camera goes unused for a while. :ahhh

@Comis
I have some L91 and L92 for emergency but I don't use themm I have these batteries to be able to use AA/AAA lights if for some reason it is not possible to recharge the Eneloops.
I have a old large stock of Eneloop and Fujtsu but I don't even use them, they are only for SHTF (I prefer 18650 battery lights)
Four L91 / L92 batteries cost approximately 7 euros, it seems a lot but it is a good price because they have a lot of autonomy and the duration in the time exceeds the expiration date on the package.
The ability of L91/L92 to work well in extreme temperatures (cold) is also important.
Forgiving Eneloop leaves me very puzzled too!
A leaking NiMH battery is an exceptional case.
I've never heard this, won't they be fake batteries? (yes, there are also false batteries on the market..)

I used to be a flashaholic, and all my flashlight friends used to run big incan mods from many eneloops at a time, so we do have pretty healthy sample size to learn from. It is really not that common an eneloop will leak, but from my flashlight days I know anything and everything will leak given time. A poorly designed circuit flashlight will trickle drain a battery without knowing, and eventually will kill the light.
I know you mentioned fake batteries, and yes, they are quite common if you are not careful where you get them from. But since we used to purchase batteries in bulk as flashaholics, we did take extra care to know our sources. In fact, we had learned so much about battery that one of our friends went on to eventually became one of the largest rechargeable lithium brand owner in the world, but that's another story for another time. :D

@comis
It would be nice to know how many years ago this happened (the leak of batteries)
Were there several generations of Eneloop, perhaps the first series had any problems? (it's just a hypothesis)

Honestly, it was so long ago, I can't really remember when, but definitely not within the last few years. I actually don't think it is the fault of the eneloop, but probably a faulty circuit. The eneloop leak was very mild(IIRC, just felt something liquid-y between fingers) and no where as devastating as a leaky alkaline battery, where it could corrode everything and even kept the tailcap 'shut' in some extreme cases.

Sounds like I can stop worrying about leaky eneloops then. :salute:

You guys have me wanting to try Eneloops. :facepalm:
Is there any advantage(aside from being less expensive) to using then instead of Energizer Ultimate Lithium AAs and AAAs?

More environmentally friendly (because they're reusable). :dunno:
They're also the best value battery option, if that's something you care about. Alkaline batteries are like $0.5 per battery, while the 2450mAh eneloops are like $4 per battery, but can be practically reused a hundred times. 1900mAh eneloops are cheaper, and can undergo more charging cycles.
While those Energizer Lithium batteries are the best by far, that does come at a price. :D
In terms of electrical performance, eneloops are in between Alkaline and said Lithium.
(BTW, the slow but smart charger I use, BQ-CC17, works great, cost €20 and came with 4 1900mAh eneloops. There are faster smart chargers for a little more money.
And all "low self discharge" "pre-charged" batteries that are "made in Japan" are made at the same Fujitsu factory that Japanese eneloops are. So you aren't limited to buying eneloops. Example: Fujitsu sells them under their brand name.)

Thank you very much, Pabs! :salute:
Definitely worth getting back into rechargeable batteries again. My only experience with them is limited to the rechargeable NiCd and rechargeable alkaline batteries from the 90s(which weren't great and got set aside when they couldn't run my digital camera and other modern high-drain devices). Will be nice to try the NiMH, with Eneloops. :)

No problems. :tu:
If you're coming from 90's NiCd, be aware that NiMH doesn't have to be empty to charge, as there's no memory effect. They can be topped up even if they're only half-empty.
In fact, not discharging them all the way makes them last for more cycles. :think: But that's not a big deal for little batteries.
(I understand that memory effect was a known issue with NiCd.)
-
:cheers:
Battery memory...oh smurf...the worst enemy of NiCd. I ruined a lot of 9.6v NiCd battery packs for my R/C cars before I knew about that. :facepalm:
The rechargeable alkalines leaked a lot of the time, but worked fairly well for a dozen cycles or so. The NiCd batteries lasted more cycles, but making sure the batteries were dead before charge was a chore. Leaving incandescent lights on would drain them well enough though. And the drain curve was bad. :dwts:
Thank you again for the help! :salute:

White Eneloop = guaranteed for 2100 cycles (2000/19000 mA)
Black Eneloop = 500 cycles (but they are around 2450 mA of capacity)
The black version has more autonomy but also more expensive.
I prefer Eneloop or Fujtsu (white) they cost less and have longer life.

:iagree:
Black has higher capacity, and white lasts for more cycles.
All my eneloops are white also, as cycles are more important than capacity for me.
If I need more capacity, I bring an extra battery. :D
-
For me its cost over time. I have not purchased AA/AAA batteries in a while (2012). I bought them from Costco during xmas. I have the 2100 cycle and lessor cycle ones as well. I cannot tell you how happy I am using rechargeable over non. During xmas Costco has them on sale or you can try the Ikea LADD or Amazon Basics but read up on those just so you're clear on how they stack up against Eneloops. As for your cells for your camera, just carry a more recharables if you find them draining too fast for your comfort. My partner photographed MMA fights locally and did just that with her flash.

I think the eneloop is light years ahead of good old nicd or even most nimh cells, they don't have as much 'memory' problem, and no need to empty to charge everytime. If you are into rechargeable, they are really nice to get.
Personally, I am just a really forgetful person, and it's hard to keep track what needs to get charged or not. So most of my AAA/AA remotes/appliances I use Lithium AA/AAA, but for stuff I use very frequently and track everyday(like my wireless keyboard/mouse), I think eneloops are the way to go.
-
:iagree: thanks, comis! :cheers:
I was thinking Eneloops for my EDC lights, digital camera, and neck fan(I use at work to keep my face from sweating while finishing wood). They are all high-drain, so the costs would even out relative to the Lithium rather quickly. But, for emergency gear and such, Lithiums are still the best option as far as I can figure. 10-20 year average shelf life, high output, lower cost, and reliability are the strong suits.
-
Yeah, lithium is best for emergency gear that needs to stay on standby. :tu:

An Eneloop is simply a Brand Name plopped on a NiMH Battery made by Sanyo/Panasonic.
I agree that they are great and can be a lifesaver if you are a Flashlight that gets sporadic use and if I were able to monitor and make sure that I was always carrying charged cells on the job every day.
I am not though and experience has shown me 2 things about this.
1-I will simply not have working batteries when I need them if I am required to keep charged units with me during work.
2-I will be OK with regular Alkaline Batteries as long as I make sure to use them quickly and move on to fresh ones as soon as I need them and I need them a lot.
I am trying to balance the needs of work which I can not negotiate or plan for really vs. the idea of recharging batteries all the time so that I always have them ready and I just need them faster and more than I can recharge them.
If this is not your reality for whatever reason then I am happy for you but it is not mine.

One thing I love about eneloops is the discharge curve:
(https://forum.multitool.org/index.php?action=dlattach;topic=81928.0;attach=438799)
At a discharge rate of 1 Amp, which would deplete a 1900mAh white eneloop AA in about 2 hours, the eneloop gives you higher voltage, and thus power (because power = volts X amps) than a alkaline non-rechargeable Duracell Ultra AA.
BUT! At a small discharge rate of 0.3 Amps and less, while the eneloop gives you the same discharge curve, the alkaline Duracell suddenly has a much better discharge curve. Eneloops are still cheaper over even 30 cycles though.
(https://forum.multitool.org/index.php?action=dlattach;topic=81928.0;attach=438801)
Thus, eneloops outperform Alkaline batteries at high discharge rates by a huge amount, and Energizer Lithiums outperform eneloops by a similar margin.
At low discharge rates, alkalines outperform eneloops.
Energizer Lithium batteries have a much better discharge curve at low to medium-high discharge rates than eneloops.

I know it's been a while :facepalm: ...
But I just found it. I thought I threw it away, I knew I kept it for some time as a reminder and as I wanted to take pics of the leak, but couldn't find it ... till now.
The culprit, the leaky eneloop lite.
I know I've had it for years, and the rest of the pack it came with are still going strong in other devices and flashlights, but this one ... :shrug: ... leaked. And not like alkalines leak, this one just seems like it got wet, hardly if any corrosion, no build up on either the flashlight it ruined or itself.

That's the first time I've seen an original generation Lite! :o
50-70% of my age...

I was unaware that Lite in the AA version existed (so far only seen in the AAA version) ???
Searching the web I found them, they are AA with a capacity of 950 mA and have 3000 guaranteed cycles.

I do not understand if something has changed over time, I knew that this type of battery does not contain electrolyte.
I also found an old thread on CPF where, however, a bad battery charger is also blamed.
https://www.candlepowerforums.com/vb/showthread.php?180661-NiMH-leakage-Does-it-happen
in these FAQs we talk about possible leaks but also gas emission if the battery is stressed.
In this case, I wonder if the leaked gas may seem to be an electrolyte leakage to the touch

The Lite version is made for Panasonic now, in China!
In AA and AAA versions.
When Sanyo was in control of eneloop, they were made in Japan.
Speaking of the Chinese-made Panasonic eneloop Lite, IKEA sells them too under their "Ladda" name, at a ridiculously low price. That's where I got my Lites.

:oops:
All the signs on the battery wrapper made me believe that they were made pre-2009, possibly as far as 2006. I guess what applies to the standard capacity eneloops doesn't apply here...
Like 91mm vs 84mm SAK tool evolution. :rofl:
-
I must be a high capacity battery...I also often leak.
-
I must be a high capacity battery...I also often leak.
I think DP's chart make sense, and I do remember using nimh for high draw usage back in my incan days. But for those small lights I use less often(AA, AAA), I do tend to use the Li AA or AAA to prevent leaks. Maybe it was the construction or chemistry of it, but it just never leak on me.
-
My Sidewinder wouldn't work last night; and it had been a little fussy for about the past week. Had been using the light every night. Noticed the negative terminal of one of the AAs had corroded (not leaked!). Battery was a couple months old ,and had been in the light a month or less. Hard to believe a Duracell would do it. Maybe it explains why Maglite has changed from Duracell to Rayovac in terms of the batteries they pack with the lights. I put in Energizers this time.

All this is normal!
I do not use alkaline but over the years I have bought several alkaline batteries to keep for emergency, when in theory the gift should arrive towards the deadline.
Over the years I have seen Duracell lose more than any other brand (particularly Duracell Industrial)
The reliability record is given by the free AA batteries that the Fenix gives in the blisters of their AA lights (Pairdeer Industrial)
It is thought that being free they are cheap, I have lights bought in 2012 that have these batteries still without any loss.
In many cases I removed the batteries from the blister pack for fear of leaks and put them in an airtight bag but still no leaks, batteries that are now 6 or 7 years old!
Even AA Energizer (alkaline) is very reliable.
-
I use Eneloops for all my AA and AAA needs. They are rechargeable, hold the charge for a very long time and I never had one leak at me. Love ‘em :tu:

Frequent 'Duraleaks' were one factor why I switched to various brands of NiMH cells (all LSD).

Check your stuff, and remove batteries from them and store them separately if you don't use them often.
It's always a good practice to remove the batteries from things that don't get regular use. If you do discover that a battery has started to leak acid you might be able to clean up the corrosion if it isn't too bad. Wipe away as much acid as you can, then clean the corroded metal contacts with cotton swabs and white vinegar. I saved a couple radios that a friend had written off as total losses. One just needed cleaning, the other I had to make a new ground spring for, but it was a easy fix.
