Either 18650 or 26650 batteries are hot topics in the vaping and tactical flashlights world. If you’re a vaper or a flashaholic, you probably have encountered these two types of batteries that you must not miss having in your arsenal.
They directly affect the runtime and amount of power available for use. While they have plenty of advantages, they can also be a source of danger – and explosion when put under stress or overcharged or perhaps improper use. That’s why before going online and finding your vape or torch battery pack, be aware of certain terms and compare the batteries based on your intended purpose.

For example, will you be using the 18650 for sub-ohming, or vaping through an atomizer, which has coils for vape having a resistance value of fewer than 1.0 ohms? Or will you use the 26650 or 18650 for torches? Before looking into the best models on the market, you must learn about certain often confusing terms you’d read on the label. Let us guide you below.

Breaking Down Battery Terms
What is mAh?
In batteries, it refers to milliamp hour, measuring the unit’s electrical power over a certain period of time. This term is also used to refer to a battery’s total energy amount that it can store at a certain time. Referring to mAh when buying, you could tell the battery’s capacity or strength because the higher its rating – means the battery will perform longer.
What is C rating?
“Capacity” or C rating refers to the max and safe continuous discharge rate of your battery.
So if you find 10C, your battery can be discharged at 10X that specific pack’s capacity.
C rating also helps you determine how much the battery can safely be charged. You will find the C rating together with the mAh rating. And then the result is the power capacity of the unit can supply you in an hour.
What is Ah?
As mentioned, it’s the ampere-hour, or Ah – sometimes also called the amp hour. It simply describes the energy amount in your battery. That energy will let one current ampere to flow for 60 minutes.
What’s an ampere? It is the unit measuring the electron flow’s rate or the current present in a specific electrical conductor.
For example, a battery with 1000 mAh means that it can provide 100 milliamps for 10 hours. Conversely, one with 2000 mAh can provide a current volume for up to 20 hours. Without even saying, the higher the mAh the longer the battery would run.
In most cases, the 18650 and 26650 are lithium-ion batteries. They usually possess the same mAh rating with that of nickel metal hydride and nickel cadmium batteries.
What is 3.7V in these cells?
Most battery manufacturers use 3.7V, which is its nominal cell voltage. Such has a 2.8–3.0V typical end of discharge and a max discharge voltage of 4.2V. On the market, almost all lithium polymer units are running with 3.7V or 4.2V.
What is voltage?
Voltage describes the differences regarding the electrical potential between “the positive” and “the negative” terminals in a cell.
A greater or higher voltage is the greater difference in the potential result.
What is protected and unprotected?
These are two other words to find on the labels of batteries.
For protected Li-Ion batteries, it means that they have a small electronic circuit, which is integrated into the packaging of the cell.
This small circuit is able to protect the units from dangers, such as overcharging, temperature and under- or over- current. Protected units are safer for your devices.
Unprotected ones, on the other hand, do not contain this small circuit in their cell packaging. Thus, the batteries can have more current capability and capacity than the type discussed earlier.
They are prone to suffering from the dangers, such as short-circuiting, overheating and overcharging.
Battery size – 18650 vs. 26650
18650’s size is 18 mm by 65 mm (diameter x length)
26650’s size is 26 mm by 65 mm (diameter x length)
Both the batteries can be used to power almost all types of devices that need a battery of their size. But because of different specifications in your devices and the batteries themselves, you must find which one to use for your specific needs and purposes.
For example, 18650s can be used alone or with other batteries to build power banks and battery packs. These are used in recharging a device. In many cases, 18650s can also be used directly, and they can also be replaced and removed as well as recharged.
Torches/flashlights and vaping devices also use these two battery types.
Either the size is an 18 x 65 or a 26 x 65 depends on the size required by a specific device, say a flashlight.
What’s Amp Rating?
It is simply how many amps can be pushed into the batteries safely.
Let’s now talk about watt-hour. What is it?
WH can help you approximate the runtime for regulated devices that have constant amps.
For instance, drawing 20 watts from your battery that is able to put out 10 WH can provide you with almost 30 minutes of uninterrupted vape time.
