Why Choose Tabbed Batteries?

Pre-soldered tabs eliminate the need for spot welding equipment, making these batteries ideal for DIY builders and repair technicians. The tabs provide a reliable, low-resistance connection point that can be easily soldered to wires, PCBs, or battery holders. This ensures a secure electrical connection without damaging the battery cell through excessive heat from direct soldering.

Size Selection Guide

14500 (AA size): Compact form factor, same size as standard AA batteries. Ideal for devices designed for AA batteries that have been upgraded to accept lithium-ion cells, or compact custom battery packs.

16650: Slightly larger than 18650, offering a good balance between capacity and size. Available in 2000mAh and 2500mAh options for different runtime requirements.

18500: Mid-size between 14500 and 18650. The 2040mAh capacity provides excellent energy density for medium-sized applications.

Important Notes

Tab Type Selection: Please carefully review the product images and select the correct tab type (A, B, or C) for your specific application before ordering. Different tab configurations are designed for different assembly methods and connector types.

Custom Requirements: If you need a specific tab arrangement, connector type, or cell configuration not shown in the product images, please contact us before ordering. We can accommodate custom requirements for bulk orders.

Compatibility: Ensure the battery size (14500, 16650, or 18500) fits your application before ordering. Check the dimensions carefully as these are not interchangeable.

Safety Information

Charging: Use only chargers specifically designed for 3.7V lithium-ion batteries with the correct voltage (4.2V max) and current specifications. Never overcharge.

Storage: Store at approximately 50% charge in a cool, dry place (15-25°C). Keep away from direct sunlight, heat sources, and flammable materials.

Operation: Do not short circuit, puncture, crush, or expose to fire. Do not expose to water or moisture.

Temperature: Charge between 0°C and 45°C. Discharge between -20°C and 60°C. Do not use outside these temperature ranges.

Disposal: Dispose of according to local regulations for lithium battery waste. Do not dispose of in regular household trash or incinerate.

Inspection: Do not use batteries that show signs of damage, swelling, leakage, or unusual odor. Discontinue use immediately if any abnormalities are detected.
