SAMSUNG INR18650-25R Li-ion Rechargeable Battery 3.7V 2500mAh 10C 25A (New)
The Samsung INR18650-25R is a rechargeable lithium-ion cell manufactured by Samsung SDI for equipment that demands power delivery. Its cylindrical 18650 format combines energy storage with the ability to supply substantial current from a compact cell. Designed as a component for properly engineered battery systems, it offers a practical foundation for devices that need repeated charging and discharging during operation.
The cell uses a controlled charging process in which current is regulated first, followed by a constant-voltage stage. This approach helps the battery reach its specified charge level under the conditions established by Samsung. Its performance is characterized through manufacturer tests covering discharge behavior, charging response, temperature sensitivity, and repeated cycling. As with any lithium-ion cell, actual operating results depend on load, temperature, charging practices, and overall system design.
