Compared to lithium-ion or lithium-polymer batteries, LiFePO4 batteries offer an alternative when large discharge currents, short charging times, and high cycle stability with somewhat lower energy density are required.

Dimensions: approximately 49.95 x 18.15 mm.

The IFR 18500J lithium iron phosphate LiFePO4 rechargeable battery features an elevated positive terminal and is unprotected.

High safety: Due to the solid electrolyte and cell chemistry, LiFePO4 cells are considered intrinsically safe.

Areas of application include solar lamps, industry, model making, and diving lamps.

Suitable chargers: XTAR VP2, Nitecore D4, D2.

Capacity: 600 mAh. Minimum capacity: 500 mAh. Nominal voltage: 3.2 V. Discharge voltage: 3.6 V ± 0.05 V. End discharge voltage: 2.0 V.

Discharge current (constant): 3C 3300 mA. Discharge current (pulse): 5C 5.5 A.

Plus pole (surface): elevated (button top).

Composition (chemistry): LiFePO4.

Diameter: 18.15 mm ± 0.1 mm. Height: 49.95 mm ± 0.2 mm. Weight: 30 g ± 1 g.

Charging method: CC-CV.

Safety instructions: Lithium cells may only be operated with protective electronics. Please note that lithium cells may only be used by qualified personnel. Incorrect handling or short-circuiting can lead to fire or explosion.

Other features: Lithium iron phosphate batteries are thermally stable and are not subject to memory effect. They work on the basis of lithium and are characterized by a high energy density.
