- Panasonic quality, extremely powerful, THE benchmark
Detailed overview
The Panasonic NCR18650B also exists in a protected "Button Top" version, but we prefer the unprotected "Flat Top" version offered here, as it is compatible with more flashlights and devices, being more compact (precise dimensions: 65x18 mm).
Regardless, this battery is the benchmark in the small world of 18650 batteries. Of impeccable quality, reliable and extremely powerful, the NCR18650B has a nominal voltage of 3.6 to 3.7V, a maximum voltage of 4.2V, and can drop, when fully discharged, to 2.8V. It can be recharged 500 times, via a battery charger compatible with 3.7V lithium batteries.
Beware, many Chinese counterfeits exist online, so caution is advised when buying them online. The NCR18650B batteries offered here are 100% genuine. Unmatched in terms of performance and durability, this cell is very often used as the base for other batteries, power banks, or power stations.
