The longer a car battery is in use, the more unreliable and prone to leakages they become. For this reason they should be checked at frequent intervals. When a car battery leaks acid, it is usually through the cell caps on the top of the battery, or due to damage to the body. Smart battery chargers detect and give signals to show when a battery is charged to full capacity to avoid this.
Extreme cold weather is also a factor that can lead to battery leakage. Under such conditions the battery acid inside may begin to freeze and cause the body of the battery to expand, putting pressure on the cells, similar to water pipes that burst in winter weather. Although this is unlikely to happen, it can still occur, which may result in acid leakage.
Car batteries contain a solution of water and acid. Under extreme cold conditions this liquid mixture can separate. Problems may occur if you top up a battery with distilled water and over-fill it.
Those are the only times where it would be likely that any liquid coming out of a battery would be water. For the most part batteries leak acid, a dangerous substance you should avoid contact with. Can modern sealed unit batteries leak? Sealed unit batteries have a slightly different chemistry make up and consume less water than the conventional, older type of battery and therefore do not need periodic topping up with water.
I never even considered their importance. Now I know. If I find myself in dire need of one, I sincerely hope, if I find one in time, it has a Duracell battery. NO the batteries were not old. Multimeter working normally, stored 8 months, destroyed at end of 8 months. Simple internet surfing shows that Panasonic, and Energizer, claim to not have battery leaks. I will not buy or install Duraleak again.
When I encounter their batteries I will simply throw them out. Panasonic is the only company claiming some science. The batteries should have some codes numbers or something on them, if you still have them. Never know, company might do something. Norm Hill, I feel your pain. I learned my lesson with Duracell years ago, which is partly what prompted me to write this article.
Hello to everyone! My experience with Duracell is the same. I lost one Maglite flashlight because Duracell leaked and I was not able to open it.
After that I use only other batteries. Varta, Philips and Panasonic are very good brands! We bought some in February and they were in the original wrapping, The boxes looked all lumpy and the stack of maybe 9 or more had to junk them. How long should the shelf life be?? These may have been 2 years old? I would like to know why a battery charger quits working after a battery leaks in it the first time and clean up is done as soon as I noticed the battery leaked?
Gilles Levesque; More than likely the Battery when it leaked it also shorted out and fried the electronics in the Charger. They leaked and destroyed my Motorola Walkie Talkies. When I went to go get more noted that the ones still new in the rest of the package were leaking. Walkie Talkie is messed up.
Not uncommon with Duracells these days. I have 2 Faraday cages in 2 locations with a solar charger that backpackers use, and Xtar USB battery chargers.
Ikea Laddas are as good as the Eneloops and cheaper. Have been using amazon brand rechargeable and eneloop rechargeable.
Initially, both brands performed very well. Two years down the road, the amazon rechargeable batteries are not holding a charge as well as they once did. Had to experiment a little. No leaking issues with either brand. There are soooo many brands to choose from.
Duracells are terrible now, thinking about taking them all back to costco, have about 20 packs, checked them again the other day and one more unopened pack already has leakers after only 3 months since the last check,,, Energizer litiums are the go to if not my rechargeables.
Years ago they were. I always used them. But then something changed a number of years ago. They leak. Maybe they cheapened their manufacturing processes. Who knows… But I definitely do not buy them anymore. Just a thought. Years ago, my flashlights had incandescent bulbs. As a cop, I used my flashlight a lot. They never lasted long enough to leak. They went downhill soon after Berkshire Hathaway bought them from Proctor and Gamble and started making them overseas china and packaging them in the US.
Ken, Have had a few friends ask me if ive had trouble with them as well, same thing, always leaks that ruin the device, we are all careful about where etc, so its the batteries, When they leak in the original package in a tub in my storeroom that never goes over 65 degrees and never sees daylight theres a problem. Threw out a great fluorescent lantern. Tried to clean but to no avail. Now I have the Eneloops and only buy Energizer batteries. Working through the Duracell and keeping a watch on the items that have them.
Really cool idea they came up with. I have a battery charger that will recharge all types of batteries including alkaline. Got it on Amazon. Duracell and Energizer are pretty good. Surprisingly, the cheapo batteries from Harbor Freight which you can for free with their coupon are among the ones that recharge best.
With this process, I rarely need to buy batteries. They recharge just fine. Always keep track of their temperature, and if you have a charger without a charge controller keep a close eye on the batteries because they will just keep charging until they start to leak. Note to others: Charge alkaline batteries at your own risk ; Although not intended for recharging, I know that some have some limited success to an extent. Think it was AA size. Yes, the batteries get hot if left in a charger that just keeps pushing power through which mine does.
Of them all, the worst rechargers are the rechargables. Go figure. Maybe yall let your duracell batteries get hot or had them in a hot storage for a while. In the past I have had all kinds of batteries leak. My oldest ones d cells came with giger counters, they are eveready dry cells in the area of 20 years old and are clean full 1.
Still perfect at about 1. I have used Rayovac batteries for many years, and never had any major problem with them.
They get old, I just throw them away. Shame on me. No leaks so far, but then I swap them out more often then most people do. I also have never had one leak on me. You can set it to a charge rate from MAh up to 2-amps.
It charges batteries, breaks in new batteries, cycles them and reconditions the batteries. I had a digital camera that ran on AA batts and bought a few packs of Energizer rechargeable batts. I charged them and tried to use them. The camera would turn off after 2 or 3 pictures because of low battery power. I thought I got a bad run of the Energizer batts but after buying 5 packages of them and having all of them do the same thing I refuse to give Energizer a single dime of my money.
Cutting quality saves money, but it lowers quality. And in the case of batteries it can destroy an expensive electronic item. I imagine the battery would need some kind of vent and I would think it could be made in a way to allow gas escape and yet no chemical leak. It appears there is a consensus out there that are having trouble with Duracell brand of batteries. Count Me among those that have had trouble with Duracell batteries leaking.
I try to use energizers within any expensive devices butt I mostly have an abundance of inexpensive devices around my house. I also go around the house checking the batteries about 1x per month to check for battery malfunctions. I thought I was having trouble because I moved out of a relatively warm desert-type of climate years ago. I still store batteries within a plastic box within my house these days rather than in the garage.
I am not sure if temperature extremes hurt the batteries. They just seem to last longer if stored indoors. I have not found a vendor of alkaline batteries that do not leak. In fact I switched to Duracell a few years ago because I had so many Energizers destroy devices. Meanwhile my Dad just had a flashlight destroyed by leaking Ray-O-Vacs a month after opening the package.
In about I earned a shiny 2 D-Cell flashlight for enrolling a certain number of new paper-route customers. So I boxed it up and sent it off. As I was walking home from the post office, it occurred to me that it might have been clever to put my address somewhere in or on the box….
I have a head torch where the middle battery has suddenly started getting very hot and discharging. Now the negative terminal has turned slightly darker, almost a burned look. I tried a fresh set of batteries, same problem, middle one discharges itself after a few mins of being super hot and the Duracell label starts to shrivel up right before my eyes. Probable broken head torch headlamp. Time for another? Some devices are shipped out with batteries pre-installed but a piece of plastic between the battery and the contacts, would that work as well as removing the batteries entirely?
If so, does it matter if that plastic sits on the positive or negative side? Matt I would not risk it, Have had brand new batteries in unopened package leaking in a dark cool storage closet,. I still use a combination of both. It does not actually say made in the USA, just assembled, under manufacture label rules that can be as minimal as packaging them up for sale. Duracell batteries are apparently made in China.
My solution is to open the battery compartment once a month to check the battery status. For the slightly more expensive items like mag lights or minimag lights, I am using only Energizer brand batteries.
This transition is slow for me because, like many on this site, when I buy batteries, I buy a lot or in large quantities. That is why I am still using the Duracells until my supply peters out. I began noticing trouble with Duracells some years ago about the time Ken mentioned having trouble with them too on this website. Loss of good equipment is just as big a problem as battery corrosion in healthcare. Lastly, I keep my batteries stored in a plastic bin inside the house where I can protect the batteries from temperature extremes and extremes in humidity.
I have noticed an increase in battery leakage since relocating to a wetter climate. I recently went round and round with Energizer and Duracell over a bunch of batteries that had corroded inside a sealed package…both brands.
The Duracell batteries were the worst. I have had more corrosion from that brand than Energizer. Many remote controls used the Duracell, and were corroded. I have had little problem with the C and D or 9V; all of which I have a substantial stash.
Most were purchases at Sam;s club. I never liked Duracell anyway. Years ago they were alright. Then something changed. Now they leak. Just purchased 10 light up ornaments that are really ornaments that go on tables. They are pretty big and I love the scenes in them. I am hoping it is the batteries, but they are new. I am afraid to use that light up beautiful ornament. Now I have all those ornaments and am afraid to give them to my friends fearing it might be the ornament itself causing the battery to do that.
I am just sick about this. I love they way they look and was so excited to give them to all my friends. Can anyone ease my fears here?
I have found rayovac to be bad leakers. I have Rayovac batteries in my drawer that are at least 3 yrs. Are you keeping them in a dry spot? How does alkiline vs lithium power life compare? If twice as much or more life in lithium sounds like that is way to go?
I use rechargeables around the house and in EDC. You should be aware that decent alkalines can be recharged as many as half-a-dozen times even if they are not rechargeables. Lithium are strictly use once and when it is dead, toss it. There is no recharging them. The minimag using LED bulb lit up bright and strong.
On digging through my battery box, I did find some corroded Duracells and they got tossed out along with the defunct headlamp. I have used it at work off and on for several years before it finally gave up the ghost. The reminder article came at a time when the days are getting shorter and I use flashlights and headlamps more frequently at my place of work.
Losers… fix the problem! I seem to be among the minority here. For the past 2 or 3 years I noticed Energizer batteries not Max corroding in everything I used them in. A few of the devices were not used often, other devices were used at least once a week. Today a TV remote was not working the way it should. I cleaned it all up; the batteries still had a very good charge. After quite a few years, so far so good.
Thank you very much for this. I was mainly curious why batteries leaked, and why I was using baking soda for my car battery, but vinegar for house batteries. I have a recording device that has stopped working from the batteries, though still works when plugged in. THere is no visible sign of leakage on the terminals, and the batteries themselves look fine, but i did notice that the masking tape i was using to protect the batteries and keep them in place i lost the battery compartment cover has gone a pale green colour over the bit where the batteries were.
It a remote where the buttons light up. I dont no if that has anything to do with it but eventually and even sometimes right away batteries leak. Alkaline and Zinc Carbide? Triple AAA batteries are notorious leaking too. Battery leakage commonly known as battery acid is nasty, corrosive stuff — it can burn your skin, contaminate soil, and of course ruin whatever device it has leaked into.
For lead batteries, sulfuric acid is the dangerous residue, which requires a different type of clean-up. Leakage from an alkaline battery is caustic and handling should be avoided to prevent chemical burns. If attempting to clean battery leakage from a device, proper safety equipment would be advised i.
