Rechargeable 280mAh CR2 Li-Ion Batteries with 3.0V average working voltage (4.5V at peak without load).

Replaces most of CR2  primary Lithium battery for digital cameras and flashlights. Tenergy RCR2 can be recharged up more than 300 times. 1 RCR2  Li-ion > 300 CR2  Primary Cell.

Internal voltage regulators modified voltage to achieve average working voltage of 3.0V.

Internal over-charge and over-discharge protection to prevent battery over use. The current will be shut off when the battery voltage drops below 2.0V.

Dimension: 15±0.5mm (D) x 27mm±0.5mm (H).
