Comparing Different Button Cell Batteries LR44, AG13, LR1154 and
A button cell resembles a button, thus the name. It’s a single-cell battery often used to power small devices like hearing aids and wristwatches.
Its diameter ranges between five to 25 mm (0.197 to 0.984 inches), while its height dimensions are between 1 and 6 mm (0.039 to 0.236 inches).
The battery has two terminals:
- The positive terminal is composed of stainless steel and lies at the bottom.
- The negative terminal is insulated and forms the top cap.
Button cells are famous for their longevity. They possess a low self-discharge, which allows them to keep their charge for a long time (especially in cases of inactivity).
Today, we’ll explore button cell batteries, their composition, and the different types.
Battery Cell Chemistry
There are four major categories into which cell batteries are grouped:
Alkaline Batteries
Alkaline batteries match other battery types in terms of size. However, they provide less stable voltage and less capacity than their lithium and silver oxide counterparts.
Silver-Oxide Batteries
Silver-oxide batteries are known for their stable discharge. They’re often used in medical instruments and precision devices.
Mercury-Oxide Batteries
Mercury-oxide batteries have stable voltage but are no longer used because of their toxic nature. Incorrect disposal of the battery pollutes the environment.
For example, the United States, through its Mercury Act of 1996, prohibited the use of mercury in favour of mercury-free alkaline batteries.
Zinc-Air Batteries
Zinc-air batteries have the highest capacity compared to others. In addition to the ingredients packed in the cell, these batteries use oxygen from the air as a depolarizer.
They’re termed next-generation batteries, given their potential to hold more energy, their safety mechanisms, and potentially reduced cost per unit.
Battery Chemistry Comparison Chart
IEC 60086-3 is an international standard that defines battery cells using an alphanumeric code format.
The IEC 60086-3-5:2021 particularly provides the requirements, dimensions, designation and methods used to test batteries used for watches.
Our 2022 Transparency Report has landed
I have used many TacLights throughout my life, starting from the Navy, private security, and SRT work. I saw this add from Nitecore for a 4400 Lumen EDC light for about 130.00. I was very skeptical but I had to at least give it a try. 4 years later, I still use the same light while on duty and when I am traning with my SRTeam. I had a PowerTac, Fenix, the popular Streamlight and Helius. I know there are more out there but my i4000R is by far the best I have used. I am now looking at getting the new TM12K in a few weeks. I definitely recommend Nitecore to anyone. especially security and law enforcement.

Chinese Company. With No Support and Products that Break
This yet another company from China that produces products that start off great, AND THEN STOP WORKING. Glitzy Marketing, and Shiny Products that look cool, BUT BREAK EASILY.Once broken. THERE IS NO SUPPORT, let alone NO Support in the United States; THERES NO USEFUL INFOMATION on their website.
My MT1A Flashlight, started off great; Then I changed the battery. IT STOPPED WORKINGTried various AA batteries on the chance that some were slightly different. DID NOT WORKTried extending the spring. DID NOT WORKSo now I have an expensive flashlightThat does not WorkANDNo company Online Support No telephone support (Unless you CALL CHINA)Have to try Emailing China about the warranty
This is a lousy customer experience, and as you can READ on the other reviews, not an isolated occurrence.AVOID. There are better alternatives made in the USA

Orders slow at first, but!
At first shipping speed sucked. I finally received a fantastic product. I also ordered a same model light from their licensed dealer, Lumen Tactical (super fast shipping by the way). The L.T. light I ordered had a strange bright white flash just before colored options came on. L.T. is taking care of this promptly. I also decided to order two low temp batteries for the devices. those came in record time and work perfectly 😉 I gave a 1 star review at first. but these guy have turned around and have a fabulous product! Unfortunately, sometimes you get a lemon. This is life!

Premium prices, poor electronics. After the brief warranty you’re on your own
Since 2013 our household has purchased a number of Nitecore flashlights for use in both our house and vehicle. During this time we thought we were paying a premium price for sturdy, well-made products that would last. But after a recent experience with one of their products failing due to poor quality, we’ve changed our minds about this brand, especially after their disappointing response.
One of the lights we purchased in late 2019 (which was delivered in January of 2020) began failing late last year. It had seen only careful, intermittent use in a kitchen drawer. If the light had had a total runtime of an hour by that point we’d be surprised. And yet the light was suddenly flickering on the highest setting. We did a bit of research online and found some other accounts of this occurring, including YouTube videos about it. It was suggested that these Made in China products are perhaps sloppy in the way their internal electronics are manufactured and assembled.
At the beginning of this year, we contacted Nitecore about what could be done about this issue. And we were disappointed that the response was Sorry, but our warranty is only two years and you’re beyond that. The fact that we’ve patronized the brand for a decade, purchased a slew of their products, and that in our state (Washington) there is an implied warranty of merchantability that suggests that a product should not malfunction within four years of purchase, didn’t matter to Nitecore.
Nitecore’s solution was to offer us a coupon off the purchase of a new 160 flashlight. Or, we could pay more than a third of the original cost to send the flashlight off to China for 12 weeks to have it repaired. Neither of those options sounded very good to us. How could we now purchase another new product with the new knowledge that it might similarly fail, and that Nitecore would be stand by it?
So our solution will be to sell the (working) Nitecore lights we have on eBay and to permanently depart the brand, never to return. We regret buying from Nitecore in that they do not stand by their products or value their customers. We’ve filed complaints with the state’s Attorney General and the BBB (which Nitecore just ignored) and will be posting online reviews so that other customers may be warned that while Nitecore sells at a premium price, they do not seem to make premium products that last. Nor will they be that concerned when their products fail after a relatively short time.
We take meticulous care of the things we have. And we’re confident that there is nothing we did to this light to cause it to malfunction in this way. And yet Nitecore is not standing by the quality of their product.
Our money didn’t break after we gave it to Nitecore. Their products shouldn’t break after they give them to us.

The 10 best IKEA sofas of 2023
It’s a new year and although we haven’t been getting any IKEA Catalogues since they discontinued in 2022, we are still continuously inspired by IKEA’s digital brochures and never-ending trendy looks, just like how we’re here to guide you on our 10 best IKEA sofas this 2023!
To help us narrow down our top picks for this year, we focused on these criteria in our IKEA sofa reviews:
- Popularity: How long has it been on the market?
- Variety: How many sizes and styles are there to choose from? How does it fit in different rooms and spaces?
- Aesthetics: How pretty is it?
- Comfort: Which is the most comfortable Ikea sofa?
(Dishonourable mention: the Knopparp “sofa”. A little fabric on a frame does not make a sofa. Even an outdoor lounge chair has more integrity this metal monster.)
TABLE OF CONTENTS
If you prefer watching a video, take a look at our “10 Best IKEA Sofas Of The Year here:
Äpplaryd
The stylish Äpplaryd comes in several variants, colours and fabric material. This sofa does not only look chic in all of its colours, but is also comfortable enough to be sat on for long hours. It’s poofy and bouncy cushions make it nice for you to plop down anytime. And if you’re feeling tired, rest your head on the pillow-like armrest and wander into dreamland.
With a width of 167cm, the loveseat is pretty spacious for 2 people. There’s also the 3-seater and 4-seater with chaise lounge that are as wide as 198cm and 273cm respectively.
The IKEA Äpplaryd comes in suave grey/black and light grey colours, with a material made of cotton, polyester and viscose/rayon. It also comes in classy velvet dark blue and velvet red/brown, which gives any space a touch of personality and sophistication.
Status: Available!
Grönlid
The Gronlid is all about comfort. It sports thick, overstuffed cushions that make you feel like you’re sitting on square clouds. Thankfully, they are also very supportive to prevent you from being sucked into the couch.
Mixers and matchers would be pleased to hear that the Gronlid has all the footstools, corners, and lounges needed to really grow the sofa. Though it’s size and clunkiness takes up space rather fast.
Compared to its direct rival, the Ektorp, the Grönlid’s deeper seating is well welcomed for a more relaxed sitting session. It goes well with the cushy cushions and makes the Grönlid one of the ultimates in IKEA comfort.
Despite coming in ninth place in this list, we’re still big fans of the Grönlid for how comfy it is, though IKEA US was apparently not as much of a fan as we were. It’s been slightly “adjusted” into a newer model called the Harlanda to better accommodate the western market but the good news is that the Grönlid still remains available pretty much everywhere else.
Status: Replaced by Harlanda in the US. Available elsewhere!
Farlov
Elegant and fancy-looking, the Farlov’s design isn’t what you’d be expecting when walking into an IKEA showroom. Low banana-shaped armrests with generously sized cushions give it a classy yet traditional feel rivalling the looks of some of IKEA’s more upmarket competitors.
The series has a few variants – loveseat, 3-seater, sofa bed and armchair. Deep seating with plush cushions make it very appealing to lounge and sprawl out on. Furthermore, the lumbar cushions help support the back when more upright seating is wanted and can even be propped on the low-sloped armrests for great nap times.
Its yarn-dyed fabric (white) and velvet fabric (olive green and dark grey) are good additions to a simple interior design.
Status: Available!
Stockholm
Coming in at seventh place is this stunning sofa from IKEA’s Stockholm collection. Specifically, the Stockholm 2017 version. It looks absolutely beautiful with its contemporary style that visually conveys comfort.
Landskrona
As the couch that ended the Karlstad in 2015, the Landskrona had big shoes to fill. We say it did a pretty good job at it too!
While not as affordable as the Karlstad, one look at this couch will let you know it conveys some visual punch – especially in golden brown leather. A clean silhouette with sharp lines and beautiful tufted cushions seal the deal as one of IKEA’s classiest couches.
With comfort on par and an included chaise to sink into for nap time, it’s easy to see why the Landskrona has won the hearts of so many IKEA fans – us included.
Those looking for the Landskrona in the US will find it better known as the Morabo, which has ever so slightly different dimensions but is practically the same thing.
Status: Replaced by Morabo in the US. Available elsewhere!
Ektorp
Where do we begin with IKEA’s cult favourite? The classic round armed design makes the Ektorp a hit among those who want a traditional style, and it’s clearly popular with the relaxed, modern farmhouse homes.
The slipcovered style with the long skirt and corner pleats play a big part in how the sofa is perceived as a more classic sofa, but once upon a time IKEA did sell leather Ektorps, complete with exposed legs and a skirtless, upholstered look.
We’ve also hacked the Ektorp, and aside from its timeless style and versatility, the comfort factor puts the Ektorp amongst the top for most comfortable IKEA sofas out there.
Status: Replaced by Uppland in the US. Available elsewhere.
Friheten
After the massively popular Manstad sofa bed was discontinued, a few models with similar mechanisms rose up to fill the void in our hearts. The one that has lasted through the years and came out on top was the Friheten, an L-shaped sofa bed with storage under the chaise and a hidden bed compartment.
Even though it’s not the most comfortable IKEA sofa, it definitely earns its points for its versatility as a sectional sofa, the roomy storage compartment, and the pull-out bed that can transform your sofa into a double bed for guests.
The Friheten series consists of a 3-seat sofa bed (sans chaise and storage), corner-sofa bed with storage and armchair.
Status: Available!
Vimle
The Vimle deserves top spot on the 10 Best IKEA Sofas list for many good reasons.
Firstly it looks great. There’s a good reason why square arm sofas do well – the look is timeless and never gets old, so it works well for almost any living space.
A quick test of this sofa will make you realise it’s super comfy (not as comfy as the reviewed Gronlid sofa but very close). The frames are exactly the same, only the arms (and seemingly cushions) are different.
To top it off, it’s very practical because the ottoman and chaise come with storage AND each part can be easily combined together to form a giant sectional, just like the Norsborg. You can even get it as a sofa bed or expand it with a sofa bed module. Talk about functional.
What’s there not to love about the Vimle? It can do everything!
