11 best aaa batteries

AAA batteries are a common type of household battery widely used to power various small electronic devices. These batteries are part of the cylindrical battery family and are smaller in size compared to AA batteries.

Key features and information about AAA batteries include:

  1. Size: AAA batteries are cylindrical in shape and have a standardized size. They are smaller in diameter and shorter in length compared to AA batteries. The abbreviation "AAA" stands for "Triple-A," indicating the size category.

  2. Voltage: AAA batteries typically have a voltage of 1.5 volts, which is the standard voltage for many disposable alkaline batteries. This voltage is suitable for powering a wide range of low to moderate power consumption devices.

  3. Chemistry: The most common chemistry used in AAA batteries is alkaline.Alkaline batteries are widely available and are suitable for everyday household devices such as remote controls, clocks, flashlights, and small electronic toys.

  4. Rechargeability: While disposable alkaline AAA batteries are the most common type, there are also rechargeable AAA batteries available. Rechargeable AAA batteries are typically nickel-metal hydride (NiMH) and can be recharged and reused multiple times, making them a more eco-friendly and cost-effective choice for certain applications.

  5. Applications: AAA batteries are used in a wide range of household devices and small electronics. Common applications include TV remote controls, computer mice, wireless keyboards, portable radios, small flashlights, digital cameras, and various children's toys.

  6. Longevity: The longevity of AAA batteries depends on the specific device and its power requirements. Lower-drain devices, such as remote controls, can typically operate for a long time on a single AAA battery, while higher-drain devices like digital cameras may require more frequent battery replacement.

  7. Storage: To prolong the shelf life of AAA batteries, it's recommended to store them in a cool, dry place away from direct sunlight and extreme temperatures. This helps preserve their performance when they are needed.

AAA batteries are a convenient and essential part of household supplies, providing power to a variety of everyday devices. Whether you choose disposable alkaline AAA batteries or rechargeable NiMH AAA batteries, they are a reliable source of energy for your small electronic gadgets and appliances.

User questions & answers

Question: What is the battery capacity (in mAh
Answer: I'm sorry not sure
Question: Why does the picture on the battery indicate it is not disposable
Answer: You can dispose of household batteries with your regular trash. There used to be mercury in batteries so they used to say not to throw them away with regular trash, but that's not true today. I believe the picture may mean to not recycle the batteries, but I'm not sure.

User questions & answers

Question: What is the mAh rating on these
Answer: Every battery has a mah... the difference is that they aren't chargeable and lose Mah once you use them. So in other words the Mah number is only good for first time use. After that it diminishes. Its like telling time after you get done saying it its already gone. I would say it starts at around 16000 mah.
Question: When do these expire
Answer: There's no expiration date on them. They don't last.
Question: Are these the brightest for flashlight
Answer: As best as I know, these are the brightest made for any flashlight. I suggest you check the internet for information about lumens, etc. I would also advise you to be very careful about what you buy. I bought a 12 pack of D batteries from this vendor and not one of them worked. The box was the same as pictured here and said "New".
Question: Why does it say .04 cents a count when it's .53 cents a count? Very misleading, not happy
Answer: Let's see, .04 cents × 48 batteries = $1.92 + tax. In my opinion it's pretty obvious that it's a misprint. Get over it!

User questions & answers

Question: To all who left reviews: How long had you been using these specific batteries from Amazon when you left review? Does your review still stand today
Answer: After my original purchase was exhausted, I switched back to my original choice which is Ray-O-Vac. I had purchased the AC Delco because they had seemed to be comparable to my original choice but we're just a bit cheaper. The AC Delco batteries do tend to last for quite a long time when used in devices that do not require a lot of constant power. Such devices include remote controls, flashlights that are used periodically or in your bathroom scale. I personally do not recommended for high power usage such as battery operated lights that you would use to read a book, hang over your bed, CD players or MP3 players.
Question: When do they expire
Answer: I bought this 48 pack of ACDelco AAA batteries in April 2016 and the expiration says: "Use By 2025"
Question: What's the expiration date on them
Answer: It says if left in normal conditions , which means room temperature and darkness , they will last 10 years. Cold definitely wears them down real quick !! Expiration dates are over rated on most products other than food.
Question: To all who left reviews: How long had you been using these specific batteries from Amazon when you left review? Does your review still stand today
Answer: Im sure this doesn't apply to you at this point, but for anyone else wondering, this batteries are great. Left my review after using about 20 of them, and have now gone through all but about 5 of them. Saw this while checking to make sure they were still available and if so add them to my cart. These are great batteries for the price. If you are looking for something sensitive that absolutely has to have high end batteries for whatever situation your device is in, I might not grab these, but that's with anything cheap vs. the best. These are great though for throwing into things that eat batteries. I use them in my bose headphones because I always forget to turn them off, and I dont feel bad about it because even if I never turn them off, ever, this pack still lasts a year or more. would last waaay to long if i actually remembered to turn them off.,

User questions & answers

Question: what is the mah
Answer: A: It means milli-Amp-hour - milli being 1/1000 of an amp. It is a measure of "capacity" of the battery, the higher the number, the higher the capacity. These batteries have a rating of 4000 mAh or 4Ah (4000 divided 1000) meaning they will provide 4 amps of power at 1.2 volts for one hour. In other words, the higher the rating, the longer the battery will provide power
Question: Do they stay 1.5v till the end
Answer: No battery will stay 1.5 volts till it dies. Any Alkaline will hold it max voltage till just before it dies. The question is. Does it stay at 1.5 volts longer than other batteries. That answer is yes. EBL batteries are the best I have ever used. Forget all the other batteries. If EBL makes it use it. They do not make a wide range of batteries. Google the EBL battery you might be looking for. Then hunt for the best price. Do not forget to check the expiration date before buying.
Question: Where are they made in? Thank you
Answer: I asked the seller a question about the model, but he did not bother to respond ..., So I searched for information on several websites ..., And I came up with the following result 1- It was manufactured in China ,,, (and [Technical Support Contact Number] in Los Angeles ,,, but when you search for it in Google, you will see that there are other companies that use the same number !!! 2- These specifications are taken from the newegg website: Size: AAA Model: LR03 Chemistry: Alkaline Voltage: 1.5V Shelf Life: 10 years Mercury, Cadmium: No
Question: Are these AAA batteries can be recharged
Answer: No, they are not rechargeable batteries.

User questions & answers

Question: These batteries for the rechargeable ones for an every day hallway light motion detector
Answer: Energizer Ultimate Lithium batteries are not rechargeable. Although they would probably work well in an AAA-powered motion detector, these batteries must be disposed of (preferebly, recycled) when depleted, and keeping your motion detector powered with these would be expensive. Primary (non-rechargeable) lithium batteries like these are best for infrequently-used devices, especially ones exposed to high or low temperatures, like an emergency flashlight that you keep in your car. You would probably be happier with rechargeable NiMH batteries for a constantly-used device like a motion detector.
Question: what is the voltage? Are these lithium rechargeable
Answer: Actually they are rechargeable, but they are not meant to be. You shouldn't use a regular charger, and certainly do NOT use a lithium charger. You should know what you're doing and do some experiments first, then know they aren't going to last either. Normal rechargeable batts don't last anywhere near as long as advertised either, but these will last even less. I haven't experimented with these nearly as much I have with other batt types, but I figure it's worth it to me to get one good charge outta them, then I toss 'em. After a charge I use them like I would alkaline batts, meaning I only put them in things that don't matter, like cheap flashlights etc. I wouldn't rely on it to work after sitting for ten years. It may still work, just saying I'll stick to oem for important stuff and looong shelf life. I can say that so far none of these have leaked out to ruin anything, like alkaline do, recharged or not... If you ask "How do I charge them if not with a regular charger", then I hate to say it but if you have to ask you probably shouldn't try. And most, once they hear how, would be unwilling. If you/anyone is still interested; use low current and be wary of it. Like charge it somewhere it can't hurt anything if things goes south. The worst thing I've ever had happen in decades of messing around with batts is they vent alkaline, or acid depending on the type, and make a mess. So far I've had better luck with Energizer Lithium than any other non-rechargeable batts, but I usually only charge the AA since I use those most. Second most is button cells, specifically 2032 cells of whatever quality brand. Button cell charging started because all the ones I tried had too low of voltage for my car remote. The car would say "batt low" in one to a few days. So I charged them a little, I guess whatever was missing since they were made, and now they last months. The smaller the cell less the charge rate, so you need a multi-tester, resistors, pots/rheostats etc to get it right. For AA I'd est 100mA or less is a good starting point. AAA I guess 50mA. 2032 I rekon 5mA. be certain of polarity and never let the batt get warm. This all applies to alkaline too, if you want to bother with them but may be nice in an emergency, like shtf ;)
Question: How many mah are in each aaa battery
Answer: Thank you for reaching out to Energizer. Each battery carries 1250 mAh. For any further information you can reach out to us at [email protected] or can call us at 800-383-7323.
Question: These batteries get hot when I charge them. Anyone know why
Answer: You CAN recharge lithium batteries (even if they don't say that they are rechargeable) if you use a charger that SPECIFIES that it can charge LITHIUM batteries. I purposely bought the Opus BC-T3400 (here on Amazon) and it does recharge my lithium batteries without overheating them when set on a lower lever charge rate.
