Rechargeable Lithium Battery Voltcraft VC-14500 3.7V 1000mAh Flat-Top

Voltcraft VC-14500 is a rechargeable lithium-ion cell with a nominal voltage of 3.7V and a rated capacity of 1000mAh. The flat-top terminal and 14500 form factor make this battery compatible with a range of devices that accept cylindrical lithium cells of this size. It provides higher energy density and longer runtime compared with standard disposable cells, and is intended for repeated charge-discharge cycles in portable electronics.

Advantages

The Voltcraft VC-14500 delivers a compact, rechargeable energy source with a stable nominal voltage of 3.7V and a moderate 1000mAh capacity suitable for small devices. Its flat-top design ensures compatibility with equipment that requires a non-protruding positive terminal. As a lithium-ion cell, it offers better energy density and cycle life than many primary cells, enabling extended use between charges while reducing the need for frequent battery replacements.

Suitable for

• Flashlights and headlamps designed for 14500 cells
• Portable electronics such as small radios, sensors, and handheld devices
• Battery packs and DIY electronics projects using 14500-sized cells
• Small appliances and tools that specify 3.7V rechargeable cells

Key specifications

• Cell type: Rechargeable lithium-ion (cylindrical)
• Size: 14500 form factor (approx. 14 mm diameter, 50 mm length)
• Nominal voltage: 3.7 V
• Rated capacity: 1000 mAh
• Terminal type: Flat-top positive terminal
• Intended use: Rechargeable single-cell applications and battery packs

How to use

Charge the cell with a charger designed for lithium-ion batteries that supports 3.7V nominal cells and the appropriate charge current for a 1000mAh capacity. Insert the battery with correct polarity into devices that accept 14500-sized cells and flat-top terminals. Observe device manufacturer recommendations regarding cell orientation and battery compartment fit. Do not use the cell in devices that require protected or button-top cells unless the device specification allows flat-top cells.

Usage recommendations

Use a dedicated lithium-ion charger with proper voltage and current control. Avoid deep discharges below the manufacturer's recommended cutoff voltage and do not expose the cell to high temperatures or physical damage. Store partially charged cells in a cool, dry place and follow local regulations for disposal or recycling of lithium-ion batteries.
