Samsung 25R INR18650 2500mAh 20A Flat Top Li-ion Battery – Wholesale 20+
Product Overview
An individual Samsung cylindrical rechargeable lithium-ion cell for equipment and properly engineered battery assemblies designed around its electrical and physical requirements. Select the exact model rather than relying on the 18650 size alone.
Key Features
Product Specifications

Suitable Applications
- Battery assemblies built for Samsung INR18650-25R cells
- Qualified high-discharge battery-pack manufacturing
- Compatible equipment specifically designed for 18650 flat-top Li-ion cells
These are application examples only. Confirm the equipment manufacturer's specified cell model, electrical requirements and terminal design.
Check Before Ordering
Check original model/markings, positive terminal shape, physical length, chemistry, nominal voltage, charge profile, maximum continuous discharge rating and protective circuitry. Matching the 18650 size alone does not confirm electrical or mechanical compatibility.
Charge using equipment explicitly configured for single-cell lithium-ion CC/CV charging. The correct charge voltage is provided in the specifications where verified.
Safety: These are individual rechargeable lithium-ion cells, not finished consumer battery packs. Use only in equipment or professionally engineered packs with suitable charge control, battery protection, short-circuit prevention and temperature management. Do not carry cells loose with keys or metal items, short-circuit, puncture, crush, dismantle, expose to fire, or charge unattended. Do not mix cells of different type, age, capacity or state of charge. An 18650 Li-ion cell is NOT a substitute for a 1.5V AA battery.
Package Includes & Wholesale Ordering
1 × Samsung INR18650-25R battery for each quantity unit ordered. Order a minimum of 20 units (example: quantity 20 = 20 individual batteries). Chargers, holders, wires, welding tabs and equipment are not included unless separately shown as included.
Warranty
12 Month LANplus Return-to-Base Warranty for eligible manufacturing faults. Correct cell handling, installation and protection are essential. Australian Consumer Law rights continue to apply.
