It’s getting tougher to seek out battery-powered keyboards. And I imply keyboards that run on AA or AAA batteries, not the rechargeable monstrosities that continually beg for a USB cable. Wi-fi keyboards that use disposable batteries last more than their rechargeable counterparts, and admittedly, they’re lots higher on your pockets and your sanity.
Be aware: We characteristic Logitech keyboards all through this text. Consider me; it’s not due to favoritism. There simply aren’t a ton of high-quality keyboards that use disposable batteries.
AAAs Give You a Longer Battery Life
The battery lifetime of a wi-fi keyboard is affected by a number of elements, together with utilization, design, and software program. However the dimension and kind of battery utilized by a keyboard is normally the determinate issue on this equation.
Disposable alkaline batteries are much less energy-dense than lithium-ion cells. So, in concept, a wi-fi keyboard ought to all the time last more on a chargeable battery. However that’s not often the case.
Your common rechargeable keyboard will final a few months on a cost—however provided that you purchase one thing costly just like the Logitech MX Keys and disable flashy options, comparable to backlighting. In actuality, most individuals get per week or two out of their rechargeable keyboard.
Examine that to a keyboard with disposable batteries, which can final over a 12 months on a pair of AAs. With a set of AAAs, you’ll be able to normally count on round six months of battery life.
This discrepancy is because of “self-discharge,” an issue that impacts all batteries. Even when a battery isn’t in use, it slowly loses a few of its energy. Alkaline batteries have a reasonably low self-discharge fee, dropping about 3% of their charge per 12 months. However lithium-ion batteries self-drain at a fee of three% every month in supreme circumstances, based on producers.
Sadly, battery capability can also be part of this dialog. Rechargeable keyboards are normally fairly slim, so that they typically use smaller batteries than they need to. The Logitech MX Keys, for instance, makes use of a 1,500mAh battery. Examine that to the cheaper Logitech K780, which makes use of two AAA batteries for an approximate capability someplace between 2,000 and a couple of,200mAh. (Two AA batteries would provide you with a capability between 4,000 and 6,000mAh.)
And simply to be clear, I believe that rechargeable batteries are an applicable possibility for power-hungry keyboards. The RGB lighting in your gaming keyboard will convey any battery to its knees, and a bi-weekly recharge simply makes extra sense than a weekly battery alternative.
Lithium-Ion Batteries Put on Out Rapidly
Rechargeable units finally lose their potential to carry a cost. That’s as a result of lithium-ion batteries put on out in a short time. Your telephone could have a noticeably shorter battery life after only a 12 months or two, and the identical factor occurs to rechargeable keyboards.
Technically talking, this shouldn’t be an enormous drawback. Lithium-ion batteries are cheap to provide, and so they’re comparatively secure, so they need to be user-replaceable.
However producers don’t care about system repairability. Eradicating the battery out of a chargeable system will normally void its guarantee. And anyway, such a restore is usually inconceivable with out instruments and YouTube tutorials.
So, how does the common individual deal with this drawback? They throw their keyboard right into a dumpster and purchase a brand new one. It’s an pointless waste of cash, and it takes an enormous toll on the environment.
Keyboards that use AA or AAA batteries don’t have this drawback. By design, their batteries should be accessible and simply replaceable. Yeah, merely utilizing disposable batteries eliminates the most important level of failure for wi-fi keyboards—go determine.

You Can At all times Use Rechargeable AAs or AAAs
The massive criticism about AA and AAA batteries is that they’re costly. They value about $0.50 every, however they aren’t reusable—rechargeable batteries supposedly have a bonus right here, as you’ll be able to plug them into the wall and reuse them for “free.”
In relation to wi-fi keyboards, I don’t actually perceive this criticism. A chargeable keyboard’s battery will put on out after just some years, forcing you to both purchase a brand new keyboard or buy the provides for a restore. I’d relatively spend a number of {dollars} on AAA batteries every year!
However we don’t have to argue about which batteries value much less, as a result of rechargeable AAs and AAAs exist. You may stick these batteries in any system that makes use of alkaline AAs or AAAs, successfully reaping the associated fee advantages of each rechargeable and disposable battery methods.
To be clear, rechargeable AAs and AAAs are a little bit of an funding. They usually self-discharge sooner than alkaline cells, so in case you’re apprehensive about keyboard battery life, they is probably not the most suitable choice.
Satan’s Advocate: The Downsides of Disposable
Most individuals deal with disposable batteries as a factor of the previous, which is a disgrace. Alkaline batteries are good for sure merchandise, comparable to keyboards, emergency flashlights, and clocks. The low self-discharge fee is extremely helpful.
Plus, disposable batteries remove a typical level of failure in fashionable merchandise—the worn out lithium-ion cell. Rechargeable batteries had been as soon as hailed as an environmentally-friendly different to their alkaline cousins, but company ignorance (particularly non-repairability) typically makes lithium-ion an extremely wasteful luxurious.
However I’m not going to fake that disposable batteries are good. Alkaline cells are a lot heavier and bulkier than lithium-ion batteries. And in merchandise that devour a ton of energy (IE: not keyboards), disposable batteries can change into very costly. These previous Casio electrical pianos chewed via C batteries like sweet!
Plus, disposable batteries are sometimes inconvenient and gross. Charging a keyboard is less complicated than changing a bunch of AAA batteries, particularly in case you’re bodily disabled, in a rush, or simply brief on money. And if alkaline batteries sit too lengthy, they leak potassium hydroxide, which is so caustic that it may well destroy electronics and burn your pores and skin.
And alkaline batteries carry some severe environmental considerations. They now not comprise mercury, which is superior, however their chemical contents can leak into soil and water. Plus, alkaline batteries are not often recycled, even though they comprise helpful metals and different supplies. (Alternatively, lithium-ion batteries are mainly the grim reaper of e-waste.)
I believe that the majority wi-fi keyboards ought to use disposable batteries. However I do know that some keyboards, particularly ultra-portable or RGB choices, are higher off with a chargeable cell. And hey, after residing via the alkaline period, I don’t actually blame anybody for hating AAs and AAAs. I simply need them to know what they’re giving up for the sake of comfort.
