18650 Vaping Batteries

The Samsung 25R batteries are a series of long lasting, flat top, rechargeable batteries that are ideal for use with vaping equipment. Widely regarded as one of the best batteries on the market for vapers, the Samsung 25R are designed to keep their charge for a whole day’s vaping and can last for multiple days depending on your usage. These batteries are also high quality and resistant to overheating which can be a problem with more demanding vaping setups.

The Samsung 25R batteries are rechargeable, but make sure that your battery charger is designed for Lithium-ion batteries. Like all lithium batteries, the Samsung 25R will eventually lose its maximum charge through repeated charging and will need replacing after around 750 charges. But, unlike many rechargeable batteries, the Samsung 25R has a very low drop off in maximum charge until toward the very end of their usable life.

The Samsung 25R batteries are ideal, working well for almost all vaping equipment because they have high capacity and voltage while running at a good temperature. This means the Samsung 25R will last a long time compared to most other batteries of this type while also remaining safe to use and providing the power needed.

Samsung 25R batteries have a slightly lower current rating in order to provide this higher capacity and better operating temperature. Which means the Samsung 25R might not be well suited to vaping equipment that demands higher current levels. But in general these batteries are one of the best vaping batteries available and will make perfect batteries for most equipment.

When choosing batteries for vaping equipment it’s important to look for high capacity, current rating and voltage with a low operating temperature. Vaping can be a very demanding activity on your batteries, especially if you’re a cloud chaser or sub ohm vaper, so it is important to use high quality batteries that can work hard without overheating.

A good rechargeable battery like the Samsung 25R will last for a year or two, so paying a little extra can be more than worth it in the long run. The long lifespan is just part of what makes the Samsung 25R so great for vapers.


The capacity of a battery is the energy storage capacity and is measured in milliamp/hours. The higher the capacity the more energy the battery can hold. The Samsung 25R has a capacity of 2500 mAh which means 2500 milliamps of energy can be drawn from it in an hour.
The amount of time batteries last between charging is affected by the batteries efficiency and the demands of your vaping equipment, which can vary. But in general the higher the capacity the longer the battery will last while doing the same amount of work.

Current Rating:

The current rating of a battery measures the amount of energy that the battery can deliver without overheating. The higher the current rating, the safer the battery will be to use. However, current rating has an impact on capacity. Batteries with high capacity will suffer from lower current ratings. Which means we need to make compromises when choosing batteries for vaping, deciding between batteries that last longest and batteries that don’t heat up too much.
Batteries with a high enough capacity to keep working all day and a current rating that won’t impact your vaping are ideal. The Samsung 25R makes a great vaping battery because it is long lasting but maintains a good temperature unless used on the most demanding of vaping equipment. For safety it is always best to adjust the current rating of your batteries to the demands of your equipment.


The voltage of a battery refers to the difference in electrical potential between the negative and positive terminals and affects the amount of work the battery can do as well as battery life. Higher voltage means that the battery uses less current to do the same amount of work. Batteries with higher voltage are better for vaping as they will have good capacity, current rating and operating temperatures.

Operating Temperature:

The operating temperature of a battery tells us how hot the battery will get when it is in use. If a battery gets too hot it can damage the battery or even our vaping equipment. Batteries that operate at low temperatures are safer, last longer and are more comfortable to use.


The lifespan of a rechargeable battery tells us how often it can be used and recharged before it needs replacing. Samsung 25R batteries have a very good lifespan and still retain a high level of charge even toward the end of their life. So, these batteries can still be used effectively until they need replacing unlike some which will have a very noticeable drop off in charge as they get reused.
