You can smell a chemical smell when you open the device and expose the batteries. You can see a liquid or a dried white goo. This is the electrolyte that has leaked from the battery's protective layer due to increased pressure. What do you do with a leaking battery? Three simple tips! Here we go: you discover leaking batteries in a device.

This is what you do: First, take a few precautions: Put on gloves and an apron. The chemicals may irritate your skin and stain your clothing. This can be prevented by taking these precautions. Ensure that the room you are working in is well ventilated.

Work out of reach and sight of curious children or pets. For years now, I have noticed the same problem with all of my Duracell batteries. It does not matter if they are installed in a device, or if they are in a plastic storage box designed specifically for batteries, they LEAK. I never have the issue with rechargeable batteries.

The last several years, I noticed Duracell batteries leak much more readily than other brands, that is my experience after 3 flashlights, a weather station monitor and a laser pointer all had their Duracell batteries leak and corrode and destroy circuitry and chips.

I could not fix the units after cleanup and threw them away. I will not buy Duracell again, they are equipment-destroyers. Also, I have started taking any brand of batteries out of key equipment like certain multi-meters and cameras that I rarely use. I had wondered what has changed with alkaline battery life. In the recent years past, my stored unopened batteries are leaking before they ever see service or the light of day.

I have always stored them in a temperature controlled, dark, cool closet, for future use. Now within a year or less, I am seeing ALL brands leak, while sitting in unopened packaging with impressive expiration dates.

Store brands are the worst as well as name brands such as Duracell and RayOvac. I have gone to solar chargers and am having better luck using rechargeable batteries. I will begin to stock up on lithium batteries as well, now that I know they may last longer and leak less. Maybe this is due to China-made or corporate greed cutting corners.

Batteries rarely leaked like they do nowadays. Thanks for the article. I have been also experiening Rotting batteries, big time. This is a big nightmare for me! ALmost weekly..? But not sure the charger is appropriate for the multiples..

I do it anyways,but sometimes they loose charge, too. How about adding clear polich to the edges of the batteries? Not cover the silver parts? Well thanks for the info. Be careful here! Some instruments that use multiple cells will be ruined by lithium batteries. Might not matter with only a couple of cells, but you put 4 or more of those in series and the voltage will be destructive to some instruments. In fact check out the high end Fluke DMM.

They specifically say not to use lithium batteries because of this. If you must use them, drain them some first to lower the voltage. Lithium batteries ARE a lower voltage, 1. Not enough voltage to make the Fluke work properly.

That is a good question. To date I have not experienced a leaking problem with the eneloops and I have been using them for years.

I have been using the eneloop batteries for years now, and have never experienced any leakage. This is true for eneloops installed in devices as well as uninstalled in plastic storage boxes. NO they wont. I have had rechargeable batteries leak.

Not often, but it can happen. I have also recharged standard alkaline batteries in a recharger. They take a recharge just fine. They normally only leak after repeated recharge or overcharge. I have never had one explode, although if overcharged they do get extremely hot. Recharged alkaline batteries ARE more likely to leak or lose their charge if left unused for an extended period. Alkaline batteries do not seem to have this problem. If I remember correctly, about 5 years ago approximately?

So far so good with those. Love the rechargeables. I was told by them to not use Lithium batteries as the voltage is too high. Usually parked under a pole shed in a cool climate. Is it any different for permanently installed batteries such as in cordless drills, emergency wind up radios and flashlights? My flashlight has a removable carriage that holds 3 AAA batteries, is removing the carriage from the unit while leaving the batteries in the carriage disengage them from discharging?

Ken, the carriage likely does not have circuitry, but does it have metal at the ends, which is touching the battery ends? There is such a thing as electrolysis. They become dead by a parasitic drain over time, or simply over-usage. If the batteries are still in good shape not dead , I suspect that you will be okay with them simply installed in the battery carrier. Perhaps over a VERY long time, there could be some visible electrolysis depending on the materials used at the contacts….

If the batteries in the carriage are connected in parallel, I would think they would be more prone to discharging during storage with carriage removed because of the weaker battery ies sucking a charge from the other one s.

Taking a closer look at the carriage I noted that it has a depressible button on it that isolates contact between the batteries when removed from the flashlight. Somebody was thinking. This has been a very good topic.

Generally the only way to slow the self discharge is to store at lower temperatures. The lower the temp the slower the chemical reaction the slower the self discharge. Combine slower chemical reactions with thicker viscosity of oil and slow starts!

Hey fom yonder Island, Been going around emptying flashlights and such. Great timing, I thought there was something going on with one side -the negative.

On to another article. Be well and as always thanks for your work. Be careful! Not all electronics are protected from reverse polarization, e. I would never just reverse the batteries. Just take them out and store them in the reefer.

Low temp, slow reactions. They can easily be purchased on either eBay or Amazon in various sizes. I had a big Maglite 5 cell corrode so badly it would not open. Sent it back to Maglite and they replaced it with a new one, even though it was several years old great company, btw and they had no obligation to do so.

They sat out for about 15 minutes and felt cool to the touch. I placed them together in a ziplock bag and sealed it. The next morning there was condensation in the bag and two of the batteries had leaked and corroded with black marks near the postive terminal. Wondering what I did wrong and if there are special rules for the storage of rechargeables that I may not be aware of. Any input appreciated.

The batteries will last far longer and have more of a charge than if you use a faster rate. Faster rates cause higher internal temperatures, and higher gas pressure, that is more likely to pop a seal or cause a leak.

I bought a Panasonic portable irrigator recently, supplied with 2 AA Panasonic batteries. The instructions include the following guidance see under. So they advise replacing batteries which last only for 20 mins use with AA Panasonic alkaline batteries and NOT rechargeable ones.

Before reading this I had decided to use rechargeable batteries for reasons of economy. I now wonder … can anyone tell me if there is a logical reason for the warning — or is this merely the manufacturer trying to increase sales of their alkaline batteries?

Please use Panasonic alkaline batteries AA size. It can be used for approximately 30 times with full tank usage, or approximately 20 minutes of continuous usage. Do not use rechargeable batteries. Doing so may result in the leakage of the battery leading to malfunction.

Alkaline batteries have a voltage of around 1. Rechargeable NiMH batteries have a voltage of around 1. Additionally most electronic gear design and manufacturers take into account the voltage characteristics of rechargeable batteries.

With that said, I am not sure why your particular product mfgr suggests not to use rechargeable batteries. Perhaps it is an old design… or maybe they want to sell you their own batteries ;. Thanks for reply Ken, much appreciated: it does seem to support my impression that the manufacturer just wants to increase sales of their own batteries.

Duracell battaries leak even brand new before using. This happens only in revent years. Just a few days ago took out Duracell batteries from an old radio that was not in use for over 10 years. These old batteries did not leak although discharged. All of them leaking. I have seen brand new batteries leak. Even the ones they pack along with flashlights. My take is that they are trying to boost sales of new devices that use batteries due to a slow economy. I had decent luck with Kodak batteries.

I think you are right. Duracell batteries sometimes leak even brand new before using, and I also think that this has been happening only in recent years. Just some time ago I took out Duracell batteries from an old walkman that was not in use for over 20 years. Not kidding. These old batteries did not leak. Total rubbish now. Have not had Panasonics leak, yet. Several times here it states that Lithium batteries do not leak Slugjet June 16 I invented an electronic device, and stored it for 28 years after first removing all known voltage sources.

When I took it out for inspection, a brown liquid poured out. Battery and counter were totally defaced. One transistor is slightly covered with brown residue. I do not have all diagrams, and want to name and replace it. I want to give it a wash-up, but do not know with what.

Duracell batteries are over-filled with electrolyte during manfacturing. Your local recycling centre is usually the best port of call in the first instance, or the garage from where you purchased your replacement battery. Most other garages will dispose of old and leaking batteries, though there may be a small charge for this service.

How to tell if your battery is leaking. There is bubbling liquid seeping through the cell caps. In extreme cold, the battery acid can freeze up and cause the body of the battery to expand.

The ever-expanding body puts pressure on the cells and can cause the battery to leak acid. If you want to keep this from happening, you can try keeping your car in a warm garage, or you can remove your battery and store it indoors during sub-zero weather. Overcharging your battery is another possible way you might cause it to leak.

When you charge a battery well past the point required, gases can build up and the battery may burst. An exploding battery may be the worst possible scenario, but you may get leakage or even boil most of the acid out of the battery well.
