What Batteries Don’t Leak? Best AA & AAA Batteries for Stored Gear
No AA or AAA battery is literally perfect, but some are much less likely to leak, corrode, and damage your devices than others. For important gear that may sit unused for months or years, my first choice is Energizer Ultimate Lithium. For rechargeables, Eneloop has also been excellent in my experience. Among alkalines, Energizer MAX has treated me better than other alkaline brands I’ve used.
My short answer: if you want the batteries least likely to leak in stored devices or emergency gear, go with lithium first, good low-self-discharge rechargeables second, and ordinary alkaline batteries when cost matters more than long-term storage performance.

Best AA and AAA batteries that don’t leak
For everyday alkaline batteries, I purchase the following 24-packs on Amazon:
→ Energizer Max AA (Amazon)
→ Energizer MAX AAA (Amazon)
A few friends of the blog wrote the following:
“Energizer batteries are definitely one of the best, had been using Duracell batteries and they are OK, but will still leak in certain situations.”
“Every ruined electronic device I’ve had, had one thing in common…. Duracell batteries leaking. I was, at first, angry at myself for not checking the batteries more often, until I had some Duracell’s start leaking less than 2 months after installation. I use Energizers exclusively now for non-rechargeable use.”
My own experience has been similar. Other brands may work fine for a while, but it only takes one leaking battery to damage a device. In my own use, Energizer MAX has been far less trouble-prone than other alkaline brands I’ve used.
Tip: Remove the batteries if the device is not going to be used for a long time.
Energizer MAX No Leak Guarantee
Energizer says its MAX alkaline batteries are designed to help protect devices against damaging leaks, including protection for a period after the batteries have been fully used. The company also backs its batteries with a device-damage guarantee under its stated terms.
That does not mean an alkaline battery can never leak. My point is that Energizer MAX has simply been less trouble-prone in my own experience.
“Even as battery technology has evolved, battery leaks are still a problem today. Many brands of batteries can still corrode and damage devices after being fully used.
Energizer batteries are different. Our batteries are designed to prevent damaging leaks or we will replace your device.”

Do Lithium AA and AAA Batteries Leak?
If you are looking for leak-proof AA or AAA batteries, lithium is where I would start.
Energizer describes its Ultimate Lithium AA and AAA batteries as leak-proof under normal consumer use. That is one major reason I use them in some of my mission-critical devices.
Lithium batteries also perform very well in cold weather. That matters for flashlights, outdoor sensors, emergency gear, and other devices that may have to work after sitting unused for a long time.
I purchase both sizes:
→ Energizer Ultimate Lithium AA Batteries (Amazon)
→ Energizer Ultimate Lithium AAA Batteries (Amazon)
For important gear, the extra battery cost is cheap insurance compared with replacing a device after a battery compartment has been badly corroded.

Why Do Alkaline Batteries Leak?
The familiar “white fluff” around battery compartment terminals usually comes from a leaking alkaline battery. The battery’s electrolyte can escape after a seal fails, then react with the air and leave the crusty material behind.
Age, deep discharge, heat, leaving dead batteries installed, or problems inside the device can all increase the chance of trouble.
If I know a device will sit unused for a long time, I remove the alkaline batteries. That simple habit can prevent a lot of damage.
Tip: Vinegar or lemon juice can help clean alkaline battery corrosion. I’ve used a cotton swab lightly soaked with the solution. Sometimes, however, the terminals are so badly corroded that the device cannot be saved.

Do Rechargeable Batteries Leak or Corrode?
I use Eneloop (Amazon) rechargeable batteries for some of my devices around here. I have some EBL batteries that have performed well after many years in service.
In my experience, my Eneloops have not leaked.
I would not say that a rechargeable NiMH battery is physically incapable of leaking. Any battery can be damaged by misuse, over-discharge, shorts, or other problems. But I have had very good results with quality low-self-discharge NiMH batteries.
Rechargeables are also a useful long-term preparedness item, especially when paired with a way to recharge them during a power outage.

Which Batteries Are Best for Stored Devices?
The answer depends on how important the device is and how often you use it.
For an emergency flashlight, outdoor sensor, expensive meter, camera, or other device that may sit unused for months, Energizer Ultimate Lithium would be my first choice.
For equipment that gets regular use, I like Eneloop rechargeables. They can be recharged many times and have been very reliable for me.
For ordinary household devices where battery cost matters more, Energizer MAX alkaline is still my preferred alkaline choice.
No matter which battery you use, I would remove it from a device that is going into long-term storage unless there is a good reason it must remain installed.
FAQ
The least likely AA and AAA batteries to leak are lithium batteries, especially Energizer Ultimate Lithium. Good NiMH rechargeables such as Eneloop are also a reliable choice in my experience.
Energizer markets its Ultimate Lithium AA and AAA batteries as leak-proof under normal consumer use. They are my first choice when preventing battery leakage is more important than getting the lowest battery price.
For the lowest leak risk, choose lithium first, low-self-discharge rechargeables second, and alkaline last. My top picks are Energizer Ultimate Lithium, Eneloop, and Energizer MAX when I want an alkaline battery.
Lithium AA batteries are much less likely to leak than alkaline batteries. They are a good choice for emergency gear, flashlights, and devices that may sit unused for long periods.
Rechargeable NiMH batteries can leak if they are damaged, abused, or badly over-discharged. In normal use, however, my Eneloop batteries have been very reliable and I have not experienced leakage from them.
Energizer alkaline batteries can still leak in some circumstances. In my experience, Energizer MAX has been less trouble-prone than some other alkaline brands. For the lowest leak risk in important AA or AAA devices, I prefer Energizer Ultimate Lithium.
I can only speak from my own experience and reports from readers. I have had fewer leakage problems with Energizer MAX than with some other alkaline brands, including Duracell. But both are alkaline batteries, and either can leak. For important equipment that may sit unused, I prefer Energizer Ultimate Lithium.
Alkaline batteries can leak as they age, discharge, or remain inside a device too long. When a seal fails, material can escape and create the familiar white, crusty corrosion around the battery terminals.
Lithium batteries are usually my first choice for devices that sit unused. They have a long shelf life, work well in cold weather, and are much less likely to cause the type of leakage damage commonly associated with alkaline batteries.
Remove batteries from devices you will not use for a long time. Do not leave dead batteries installed, avoid mixing old and new batteries, store batteries in a cool dry place, and inspect important equipment occasionally.
For AA and AAA batteries, lithium is usually my first choice for long-term storage and emergency equipment. I use rechargeables for equipment that gets regular use, and alkaline batteries where lower cost is more important.

Duracell batteries are the absolute worst! I’ve experienced over 20 device failures due to leaking Duracell batteries that were still well before they used by date.
I have used ever ready or energizer for the last 15 years with zero failures.
I have had RaoVac batteries leak even in my battery daddy box! 🤬
I stopped using Duracell long ago due to leakage and went to Ray O Vac which I find are guaranteed to leak so this article is a big help, now I know what to buy. Since we use AA & AAA batteries on camping trips it is more practical to use throwaways instead of rechargeables. Another con about rechargeables is that they do not charge to the same level as regular batteries and some battery operated devices I have don’t function well with the lesser charge. I use a multi-tester to measure voltage.
Now I know to use energizer. I knew Duracell was not good from your article years ago. But didn’t realize (or maybe remember) the energizer brand is the way to go.
I thought I should check an unopened box of Ray O Vac AA batteries and 5 out of 24 had already corroded. They had been on a basement shelf for a couple of years.
Hate to break it to you but Energizer alkaleak batteries leak too. They’re called alkaleaks for a reason. Do they leak less than Duracell? IDK, maybe less, but they definitely leak. I’ve had no leakage with Energizer Lithium and with Eneloop NiMH so I try to stay with those. I still don’t understand why the industry can’t make a basic consumer battery that doesn’t leak.
I have been using the Eneloop batteries for 15 years now and have never had a problem with them.
they are the best on the market IMO.I recharge them and they are good to go again.
I quit using Duracell years ago, they just destroyed some of my flashlights and radios.
Energizermax do in fact leak but it is rare.
In the last three years I have had 2 separate leaks.
Compared to duraleak/rayovac junk and others energizermax are great.
I go through my rayovac/ac-delco UnUsEd stock and throw out all the leakers, monthly I toss out on average 5 every single time I go through them and visibly see the leakers AND when testing it’s normal to find several that are completely dead.
I test before using any with a digital multimeter.
Sad as I still have a couple hundred acdelco and rayovac AA/AAA
Spending a little extra on energizer is totally worth it.
I have found it is best not to keep batteries in my devices that I want to use after storage.
I use to buy Costco batteries but they seemed leak more and more so I returned them. I do buy Duracell from Costco an i have not had an issue. Also buy battery adapters makes AA into ,C,D and D to 6v.
I’ve had nothing but trouble with Duracell, Energizer (and Max) and RayoVac. All have killed countless flashlights and many other items. Despite the article above, after finding yet another piece of equipment ruined earlier this year by Energizer, I had to throw out unused Energizer Max batteries (with 2030 dates) that were still sitting unused in the box in my supply cabinet and in a plastic bag in my truck console!
This is a small portion of the (cutoff due to length) email I just sent Energizer.
As if there were any doubts – here’s 2 photos of the EMPTY BATTERY COMPARTMENT WHICH YOU CLEARLY DID NOT ASK FOR IN THE 1ST EMAIL. Enjoy.
I had to dig through multiple bags of corrosive liquid again with yet another set of vinyl gloves – despite all the info you already had. It’s rather shocking that you and your injury team are aware that I got burns from the corrosive liquids on the back of my hand and just above the wrist last time while having to wrestle through the spreading contamination to get further unnecessary photos last time and yet you still required me off to take further pictures again.
By the way, if you’ll send me a prepaid, self addressed shipping box (about 12x12x8″), I’d love to send you the entire pile of crap so you can inspect for yourself. Be sure to make the box have a leak-proof liner and label it hazardous. Really – you seem to need so much info – this is the best fix. Please – do this.
Or, if you won’t send this box to me, I can send it to your upper management. I’m sure they’d love to make sure the claim is legit. I’ll be sure to attach all emails and photos. Would this be the correct address?
