Ansmann 1307-0002 Lithium-Ion 18650 Rechargeable Battery

The ANSMANN 1307-0002 is a rechargeable 18650 Lithium‑Ion battery with a nominal voltage of 3.6 V and an integrated safety circuit. It includes an integrated USB‑C charging socket and a charge status LED on the positive pole. The battery offers high energy density, low self‑discharge and is designed for use in portable high‑power devices and a wide temperature range.

Advantages

The built‑in protection board guards the cell against overload, short circuit and deep discharge, which increases operational safety and service life. Compared with conventional NiMH cells, the Li‑Ion chemistry provides about twice the energy density in the same 18650 size, while offering lower weight and higher cycle stability. The battery supports easy charging via a standard USB‑C cable from a PC, power bank or 5 V USB power supply, and also accepts charging on a lithium charger (max. 2.6 A). A charging LED shows red during charging and green when fully charged.

Suitable for

• LED torches and flashlights
• Headlamps
• E‑cigarettes and vaping devices (manufacturer compatibility required)
• Laser pointers and small handheld tools
• Portable electronics requiring 18650 Li‑Ion cells

Key specifications

• Brand: ANSMANN
• Model / MPN: 1307-0002
• Type: Rechargeable battery, Lithium‑Ion (Li‑Ion)
• Size: 18650 (note: protected version is ~3–4 mm longer than unprotected 18650)
• Nominal voltage: 3.6 V
• Integrated features: safety protection board, USB‑C charging socket, charge status LED
• Charging current limit (internal): max. 1 A via USB‑C; compatible with lithium chargers up to 2.6 A
• Operating temperature range: −20 °C to +60 °C

How to use

Charge the battery using a standard USB‑C cable connected to a PC, power bank or 5 V USB adapter, or charge with a compatible lithium charger (up to 2.6 A). During charging the LED on the positive pole lights red and switches to green when charging is complete. Install the battery into the device observing correct polarity and any device‑specific instructions. Because the cell contains an integrated safety board, its length is approximately 3–4 mm greater than an unprotected 18650; verify fit before use.

Recommendations

Use the ANSMANN 1307-0002 in devices that accept protected 18650 cells and respect the specified charging limits. Avoid exposure to extreme heat or mechanical damage. For storage, keep the battery partially charged and store in a cool, dry place to minimize self‑discharge and prolong service life.
