Rechargeable batteries are gaining popularity, and for valid reasons. They are more efficient, cost-effective over time, and less harmful to the environment. Nonetheless, there are appliances in the home that still require traditional disposable batteries. Utilizing rechargeable batteries in these instances is not only inefficient but can also compromise the device’s performance and longevity. There are primarily two reasons for this. First and foremost, rechargeable batteries exhibit a higher self-discharge rate. This implies that, even when not in use, the battery will consistently lose charge and deplete faster than single-use batteries.

The discharge rate is largely influenced by the chemical makeup inside the battery. For example, NiMH (Nickel-Metal-Hydride) rechargeable batteries have a higher self-discharge rate compared to their NiCD (Nickel-Cadmium) counterparts. Secondly, commonly found rechargeable batteries have a lower voltage rating of 1.2V as opposed to single-use alkaline batteries that can provide 1.5V. Consequently, many devices that depend on a 1.5V supply may either malfunction or not operate at all with rechargeable batteries. Now that you are aware of the typical drawbacks of rechargeable batteries, it’s time to discover the devices for which they tend to be unsuitable.

### Smoke and Security Alarm Systems

Smoke and security alarm systems in your home are essential devices. They are designed to function for extended periods without activation, but when the time comes, you expect them to operate immediately. Hence, rechargeable batteries are not ideal for these devices due to their elevated self-discharge rate. If you install rechargeable batteries in alarm systems, they might deplete after just a few months, much quicker than disposable batteries. Another reason is that these devices require low energy, making single-use alkaline batteries a more suitable choice.

Rechargeable batteries, conversely, are better suited for gadgets where increased power directly correlates with enhanced performance, such as game controllers. Remember that for devices like smoke alarms and security systems, it’s advisable to consult the product’s user manual before selecting a battery. Some models even come with integrated lithium batteries that can last up to ten years.

### Wall Clocks

Wall clocks do not require rechargeable batteries because they consume minimal power, something that an alkaline battery can easily support. Moreover, wall clocks are often placed at heights, making access a bit tricky. Therefore, you naturally prefer a battery that lasts longer, rather than one that runs out of charge in a few months. With rechargeable batteries, you’d need to recharge them more often, which means you’ll have to retrieve your ladder sooner than you would like.

There’s also the cost aspect to consider. Rechargeable batteries, while initially more costly, ultimately become a more economical choice due to their capacity to be recharged hundreds of times. However, this only proves beneficial if they are recharged consistently, say monthly, rather than every two years. In the latter scenario, it would take a significantly longer time to recoup the higher initial expense. Thus, it is more practical to utilize non-rechargeable, single-use alkaline batteries in wall clocks, from both a functional and financial perspective.

### TV and AC Remote Controls

Remotes for TVs, air conditioners, and similar devices consume very little energy. Most of the time, the remote is idle, resting in a corner of the room. If rechargeable batteries are used in this context, they will lose their charge over time, regardless of how frequently the remote is employed. Additionally, remote controls may report inaccurate charge levels with rechargeable batteries, since they assess battery health based on voltage curves. As rechargeable batteries operate at a lower voltage, some remotes, particularly those calibrated for alkaline batteries, may display false battery status.

Moreover, the cost consideration is also relevant here, making rechargeable batteries an unpractical choice for the majority. If a device can run for six months to a year without needing a battery change, it’s wiser to choose non-rechargeable batteries. The inconvenience of frequently recharging the battery significantly outweighs the minor cost savings you might observe in the long run.

### Backup Emergency Lights and Flashlights

Emergency or backup lights are another category of devices that do not gain from rechargeable batteries. These devices are typically used only once or twice a year, and you expect them to function without delay. Due to their high self-discharge rate and faster voltage drop, rechargeable batteries are unreliable for backup lights. In contrast, alkaline batteries experience a gradual voltage decrease. Thus, even when the charge is low, they can still activate emergency lights and flashlights.

For devices that remain inactive for weeks or months, single-use alkaline batteries are generally the superior option over rechargeable batteries. With alkaline batteries, the emergency light or flashlight will slowly dim as the battery drains, while rechargeable batteries can abruptly shut off when needed because of the sharper voltage drop. Note that some emergency lights come with built-in rechargeable batteries, in which case, continuing to use them is advisable, as per the manufacturer’s recommendation.

Costco Kirkland Signature versus Amazon Basics batteries. Even within the same battery brand, you may have to select between different types, such as Panasonic’s Super Heavy Duty or its alkaline Platinum Power version.

Perhaps most crucially, why spend extra on Duracell batteries when Amazon Basics can save you some money? Are there any evident differences between them? The response isn’t a straightforward yes or no. In theory, pricier batteries tend to outlast cheaper ones due to aspects like materials, manufacturing standards, leak protection, and even rechargeability. However, these specifics aren’t always apparent, especially when attempting to mentally rank all the well-known battery brands while shopping at the store.

Setting aside personal preferences regarding the best brand, the reply is: It varies. Certainly, specialized batteries for your Xbox controller can elevate the price due to their specific function, but regarding standard AA and AAA batteries, you generally receive what you spend. That being said, it’s beneficial to grasp what contributes to these variations in battery lifespan and whether you are willing to invest in it.

The Speculations Regarding The Upcoming Xbox Console Are Accurate, And It May Transform Gaming

It has been more than five years since we entered the “next generation” of gaming with the Xbox Series X and PlayStation 5. Depending on your perspective, the downturn of the Xbox has been quite noticeable as the continuous growth of Xbox Game Pass and the accessibility of the console’s “exclusives” on PC — and very soon PlayStation as well — has only increased thanks to the company’s extensive strategy of backing various platforms. Nevertheless, it appears Xbox is not quite ready to abandon hardware. Instead, the upcoming Xbox console will pave the way, as Microsoft asserts it can run both PC and Xbox games.

While speculation has been circulating for months, we have finally received our first concrete insight into what to anticipate from Microsoft’s forthcoming Xbox. The newly appointed Xbox CEO Asha Sharma revealed on X today that the new console, codenamed Project Helix, will “play your Xbox and PC games,” and that the gaming firm plans to disclose more about its features and expectations at GDC later this month.

And that’s the catch. We still possess limited information regarding the next generation of Xbox consoles. Sure, numerous speculations exist, but with the persistent chip shortage and soaring RAM costs — which have escalated to the point where future laptop configurations might entirely change — a more gaming console that potentially functions as a PC could aid consumers in rationalizing the purchase and provide Xbox a rationale for the pricing.

PC games are arriving on the next Xbox

Most of the rumors we’ve encountered in recent months originated in 2025, when Microsoft unveiled the initial details about its intention to launch an Xbox-branded variant of ASUS’s ROG Ally. The ROG Xbox Ally X presented an intriguing perspective on Xbox gaming, not only granting access to PC games but also allowing users to play Xbox games, provided they had a PC version. However, that’s where it stopped being an Xbox, as it lacked the ability to play Xbox-exclusive games natively.

Naturally, the ROG Xbox Ally and Ally X were merely components of the “This is an Xbox” initiative, where the company underscored all devices capable of playing Xbox games through the cloud. Moreover, with the Xbox ROG Ally achieving notable success by implementing the Xbox UI on a portable Windows device, it doesn’t seem far-fetched that the company will logically advance by making its next console more akin to a PC as well. In fact, we are already observing other companies creating living-room friendly PCs with the launch of the Steam Machine from Valve. Additionally, there’s Xbox’s ongoing collaboration with AMD. In a video commemorating the partnership, from June 2025, Sarah Bond, former President of Xbox, suggested that future Xbox consoles would not be restricted to a single storefront.

While the ROG Xbox Ally is unable to play native Xbox games, Bond reassured fans that this wouldn’t hold true for its upcoming consoles. If Microsoft fully embraces the notion of making everything an Xbox, then it will fundamentally alter our gaming experiences. Fortunately, we won’t have to wait long for further details, as GDC begins on March 9, 2026.
