The 25R5 (green) is one of Samsung's newest cells and is a direct successor to the blue 25R2 (blue) that so many people know any love. The electrolyte balance was tweaked giving this cell an excellent upgrade. Samsung has promised the 25R5 does not have improved performance over the 25R2, but has a long cycle life instead (can last more than 250 charge cycles).
Battery specifications:
- Max. continuous discharge current: 20A
- Safe pulse discharge ratings for applications like power-tools: 95A < 0.5 sec, 65A < 1 sec, 40A < 5 sec, 30A < 6 sec
- Nominal capacity: 2500 mAh
- Nominal voltage: 3.6 V
- Discharge end voltage: 2.5 V
- Charging voltage: 4.20 +/- 0.05 V
- Standard charging current: 1.25 A
- Length: 65.85 mm
- Diameter: 18.33 mm
- Weight: 45.0 g
The 25R5 (green) is equal in performance to the 25R2 (blue), however the newer 25R5 has a longer cycle life and some other small improvements.

This was one of the best 18650 cells ever made. It handles high current loads well (a max. continuous discharge of 20A) and has a good capacity of 2500mAh. As such, this has become a go-to cell for many industries. This cell is now known as the 25R2 (blue) to distinguish it from a newer version of itself, the 25R5 (green) which came out in early 2015.
The 25R is now completely replaced by the green 25R5.

The Panasonic PF was first introduced in 2013 as an upgrade to the Panasonic 18650PD. There are three main differences, a slight (20-30mAh) capacity increase, a wider top-cap for easier welds, and a CID (protection against over-charge) which has been tweaked to be more sensitive. This battery is older, but is still readily in production as it has proven reliable.
The 10A max. discharge current and 2900mAh still makes it a commendable cell for many custom battery pack applications.
Battery specifications:
- Model: NCR18650PF
- Manufacturer: Panasonic
- Chemistry: NCR
- Max. continuous discharge current: 10A
- Nominal capacity: 2900 mAh

The Panasonic B is the most famous out of all 18650 batteries. When first released several years ago it was the highest-capacity 18650 cell mass produced and thus an essential ingredient in the rechargeable revolution and for the adoption of electric vehicles like the Model S (which has been powered by the Panasonic 18650B for some years). It is still a frequently requested cell for custom packs.
Battery specifications:
- Model: NCR18650B
- Manufacturer: Panasonic
- Max. continuous discharge current: 4A
- Nominal capacity: 3400 mAh
- Nominal voltage: 3.6 V
- Discharge end voltage: 2.5 V

Note: LG 18650 cells are not authorized or intended to be used as stand-alone, removable, rechargeable power sources for e-cigarette or vaping devices, or to be handled directly by consumers in any manner. Clients who inquire about LG loose cells must intend to manufacture battery packs with proper outer casing, PCM/BMS and protection functions and be able to provide documents to prove this.
The LG MJ1 is one of the newest 18650 Li-ion batteries to enter production by LG Chemical. They boast specifications superior to all their predecessors of a certain class. They are a substantial 3500 mAh - making them one of the highest capacity 18650 cells ever produced. At the same time, what is especially interesting is their discharge rating. While most high-capacity cells trade-off for lower discharge ratings, sometimes as low as 2 or 3 amps - the LG 18650 MJ1 packs a rare 10 amps. This makes the battery ideal for more applications than most. From electric vehicles to batteries for IoT devices, the new generation of 18650s seems to be capable of doing it all. The MJ1 is poised to become a very popular model after production begins this summer 2015.
*(Update 2018) The MJ1 model is still one of the best, if not the best cell for use in high-capacity battery packs. Availability is also excellent and cost per energy is low.
Battery specifications:
- Model: LG18650MJ1
- Manufacturer: LG Chemical
- Max. continuous discharge current: 10A
- Nominal capacity: 3500 mAh

The 2013 LG HE2 18650 battery is still a popular choice among modders because of a high discharge rating of 20 amps and economical price. This battery is only rated at 20A, and can probably only sustain 35A in 1 second pulses (like the 25R), but doing so will decrease the cell's cycle life.
