Excellent battery efficiency
For maximum lasting time, Samsung Li-ion 3.7V 2600mAh rechargeable battery demonstrably have maximum energy density with small size and low weight - guaranteeing maximum output power.
Solid button top design
Protruding positive terminal creates solid contact when connecting batteries in series or installing in equipment with flat circuit board that are incompatible with flat top batteries.
Fast charge and no memory effect
Samsung ICR18650-26F 2600mAh battery can be full charged in about 4 hours, faster than Ni-MH, Ni-Cd or Lead acid batteries. Durable energy storage without memory effect and with minimal self-discharge.
Long service life
The Protection Circuit Board (PCB) offers maximum protection against overcharging, overdischarging, overcurrent, overheating and short circuits as well as extending the service life of the battery pack.
