Best 38.5Wh Battery Laptops: All 6 Compared on Specs

By Paul Syverson · Last updated Oct 20, 2026

Our top pick among 38.5Wh laptops is the NAIKLULU model with 16GB of memory and a 512GB drive: it has the most storage of the six and ties for the most memory, at a stated 1.6 kg. A 38.5Wh pack is small, so every laptop here suits desk and classroom use near an outlet more than long days unplugged. We compared all six on their stated specifications and on Intel's and Microsoft's published data, not on lab tests.

6 picks from 4 laptops that match this guide with a price we can quote today. Every price below is live and carries the moment it was read.

At 1.59 kg it is the lightest of the five laptops here that state a weight, and it pairs 8GB of memory with 256GB of storage and Windows 11 Pro. The listing describes the chip only as a 2-core Pentium with a 2.10GHz base speed, without a model number.

Pros

• 1.59 kg, the lightest stated weight here
• 8GB of memory and 256GB of storage
• Windows 11 Pro stated

Cons

• Processor model not stated by the seller, so its Windows 11 support cannot be checked
• 8GB of memory, half of the 16GB picks

Verdict: The minimum configuration here, for light office use only.

Side by side

How we picked

How we picked: our catalogue holds six laptops whose listing states a 38.5Wh battery, and because that is fewer than twelve, this page shows all six. All six have a 15.6-inch screen. Three are NAIKLULU listings that differ only in memory, storage or processor; we kept all three and say where they overlap. Several listings name the processor only in the title, so we flag that, and we checked each named chip against Intel's specification pages and Microsoft's list of processors supported for Windows 11. Prices on this page are live: each one is read from the store listing and shown with the time it was read. Nobody at wikilaptop.org has tested these units; every comparison below comes from the stated specifications.

How to choose

What 38.5Wh means for runtime

Watt-hours measure how much energy the battery stores. How long it lasts then depends on how much power the processor, screen and workload draw, so a capacity alone cannot give you a number of hours, and no maker in this list publishes one we could verify.

A 38.5Wh pack is at the small end for a 15.6-inch laptop. Light browsing and documents on a low-power chip stretch it furthest; video calls, a bright screen and heavy apps empty it quickly. Treat these laptops as desk and classroom machines that live near an outlet.

Processor: low power helps, age matters

Every chip named in this list is a low-power part. Intel lists the Core m3-6Y30 at 4.5W and the Pentium Gold 4425Y at 6W, both with 2 cores and 4 threads, which suits a small battery.

Age is the catch. Intel lists the m3-6Y30 as launched in Q3 2015, and Microsoft's Windows 11 processor list starts at 8th-generation Core chips, so the three m3-6Y30 laptops use a chip below that floor. The Pentium Gold 4000Y series, which includes the 4425Y, is on the list. If a listing gives no model number, as with the Tuonoyee, ask the seller before buying.

Memory: 4GB, 8GB or 16GB

Microsoft lists 4GB of memory as the minimum for Windows 11, so the 4GB EYY has little room beyond the operating system. Two laptops here have 8GB and three have 16GB. For a browser with many tabs, a video call and an office app at the same time, 16GB gives the most headroom.

Storage and screen

Storage here runs from 128GB to 512GB. Windows updates and apps take a share of any drive, so 256GB or more is the practical choice if you keep files locally. All six laptops have a 15.6-inch screen, which is roomy for documents but draws more power than a smaller panel; lowering the brightness is the simplest way to stretch a small battery.

Weight and makers

Five of the six state a weight, between 1.59 kg and 1.64 kg, so carrying them is similar. All six come from smaller brands. Before buying, check who provides the warranty, how support is reached and whether the listing names the processor model; the seller should be able to answer all three.

Questions

How long does a 38.5Wh battery last?

There is no fixed runtime for a capacity, because power draw depends on the processor, the screen brightness and the workload. No maker in this list publishes a runtime we could verify. As a small pack, it suits light use such as browsing and documents between charges. Plan to plug in for long video calls, bright-screen streaming or heavy apps.

Do these laptops meet the Windows 11 requirements?

On memory, yes: Microsoft lists 4GB as the minimum and every laptop here has at least that. On the processor, it varies. The Pentium Gold 4425Y belongs to a series on Microsoft's supported list, while the Core m3-6Y30 is a 6th-generation chip, below the list's 8th-generation Core floor. The Tuonoyee listing does not name its processor model.

Is a 38.5Wh battery enough for school or office use?

For classes and meetings near an outlet, yes. For long days away from power, a larger battery gives more margin. A lower screen brightness and closing background apps help a small battery last longer. If you often work unplugged, compare laptops with larger batteries before choosing one of these.

Did you test these laptops?

No. Nobody at wikilaptop.org has used these units. We compared them on the specifications stated in each listing, checked the named processors against Intel's pages and Microsoft's Windows 11 list, and we do not describe battery hours, heat, noise or keyboard feel, because those claims need testing we have not done.

Does battery capacity drop over time?

Yes. Lithium-ion batteries lose capacity as they age and go through charge cycles. With a small pack, that loss is felt sooner. Ask the seller whether the battery can be replaced and what the warranty covers, since all six laptops here come from smaller brands.
