Samsung 25r Reviews

by Staff : Mark Donley

The Samsung 25R 18650 2500 mAh 20A INR is a High Drain Battery that is one of the most popular choices currently available for sub-ohm mods. With a maximum discharge current of 20A and a capacity of 2500 mah this battery is able to produce a very clean and constant power supply while at the same time delivering extra run time.

Not only does the INR technology make this one of the safest batteries on the market it also offers better performance for a longer time period.


The Samsung 25R 18650 is popular among users of personal vaporizers as well as other devices that use 18650 batteries. The list includes external laptop battery packs, flashlights, and portable powerbank chargers. 


Let’s briefly examine this battery’s main benefits:

High energy density

A battery like the 18650 offers high energy density. This means it is able to sustain a load for a relatively long period of time compared to one that has a lower energy density. The Samsung 25R 18650 also offers an excellent balance between capacity (2500mAh) and power (maximum uninterrupted discharge equals 20A). This makes it the perfect battery for powering applications that need a lot of power, e.g. mods or vaporizers.

Impressive life cycle

For readers who are not familiar with the term ‘life cycle’, this is basically the cycle between one full charge and discharge. The Samsung 25R’s life cycle is 250, which means that after 250 cycles (from fully charged to discharged) at the peak uninterrupted discharge rate of 20A, the battery’s maximum capacity will drop from 2500mAh to 1500mAh or less.

High voltage, more current

When fully charged, the Samsung 25R boasts a total voltage of 4.2v, although the nominal voltage is 3.6v. This means the battery has been designed to run for longer periods of time, which is good news for users of both regulated and mechanical devices.

When vaping, the higher the voltage the better. If the voltage is sufficiently high, vaping users will undoubtedly get hard hits because a stronger current will be delivered to the coil, which translates to more vapor.

The Samsung 25R’s maximum continuous discharge rate equals 20A, which is perfect to make sure users get excellent performance without any chance of the battery overheating.

Solid battery capacity

The capacity of a battery is important since it determines how long you will have power before it has to be recharged. The capacity is determined by the mAh (milliampere-hours) rating, and in the case of the Samsung 25R, this is 2500mAh.
That means one can draw energy of 2500mA for a 1-hour period, 1250mAh for a 2-hour period, or 500mAh for a 5-hour period - and so on. Simply divide 2500 by the current you will be using.


The Samsung 25R 18650 is undeniably a good battery, but it has one weak point: the wraps really don’t look good. OK, this might not sound like a big deal, but there are some individuals for whom this is really important. Although Samsung has switched from blue to green wraps, that has not improved these batteries’ visual appeal to any significant extent. Luckily you can replace the wraps if they really irk you.
