***BACK IN STOCK*** Samsung INR 25R 2500 mAh 20A 18650

R 121.00

The Green Grinch's are here :)

The Samsung INR 18650-25R Battery is a 2500mAh battery uses a “Safer” INR Chemistry. You might have noticed the tube color of our 25R’s changed from a light blue to green. The blue battery is a 25R2 and the green battery is the 25R5. The 25R5 is the newest version of the 25R and according to Samsung the difference between the two is an increased cycle lifespan. A small storage capacity gain, or efficiency gain may also be a side-effect of their improved chemistry. Even more than before the low internal resistance and a maximum continuous discharge rating of 20 amps make the Samsung INR 18650-25R Battery a great choice for any vaper.

The Samsung INR 18650-25R Battery is the most recent battery released from Samsung. This 2500mAh battery uses a “Safer” INR lithium nickel chemistry also allowing for shorter recharge times. Low internal resistance and a maximum continuous discharge rating of 20 amps make the Samsung INR 18650-25R Battery a great choice for any vaper using builds above 0.2 ohms.

Battery Safety Basics

Do not overcharge or over-discharge.

To combat this, do not leave your batteries in any charger without supervision. Make sure that you are able to see or check on the charger every 15-30 minutes. This way when the charger indicates that the batteries have been fully charged, you can remove them from the charger. Leaving batteries in a charger all night long or longer can cause them to be overcharged, which can result in battery failure. Charging your battery over 4.25 volts can shorten its life-cycle and going over 4.5 volts can cause it to burst. Cease using your charger if this ever happens.

Recharge batteries with a resting voltage below 3.6V as soon as possible.

Leaving LiIon batteries in a discharged state will incur irreversible damage – creating a loss in capacity and a loss in cycles.

Determining the exact voltage can be tricky, unless you have a multimeter. If you are delving into the world of mechanical mods and RBAs (ReBuildable Atomizers), or making your own coils, a multimeter is a must have device because you can use it to test your coils and your batteries. Sure, you can always use a battery tester, but the majority of battery testers are not equipped for the types of batteries that are used in mods, or even test batteries under load condition.

Do not short circuit your batteries.

Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your mod, or even your face!

Short circuits happen when the voltage from a battery is discharged through a low resistance wire at a discharge rate that exceeds the battery’s upper amp limit. Short circuiting a battery is very close to what a mechanical mod with a sub-ohm coil is doing, except you are trying to keep the resistance under the upper amp limit – there’s a fine line that you have to be careful of when sub-ohming. 

Do not let your batteries touch each other or other metallic items. 

Keeping your batteries loose, such as in your pockets, is a good way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe. Get some – now.

Do not dispose any battery in a fire.

This is just common sense people. There are dangerous chemicals in batteries. If you try to burn your batteries they’ll release dangerous fumes and will probably explode. Do yourself, and the rest of the world, a favor by taking your old batteries to a battery recycling center.
