The IMREN 1.2V AA 2000mAh Rechargeable Ni-MH Battery is a high-performance power solution designed for long-lasting and efficient energy delivery. With its high-capacity 2000mAh cell, this battery provides reliable power for a variety of everyday and high-drain devices. Whether used in LED flashlights, remote controls, smart door locks, electric toys, or gamepads, it offers a consistent and stable voltage output to ensure smooth operation. Unlike standard disposable alkaline batteries, this rechargeable Ni-MH battery is engineered for extended usability, offering up to 1200 charge cycles, significantly reducing waste and saving money over time.

One of the standout features of this battery is its constant 1.2V output throughout its discharge cycle. This means that from full charge to complete depletion, the voltage remains steady, ensuring consistent performance without the common power dips seen in traditional batteries. This stable power output makes it particularly ideal for devices that require sustained voltage to operate efficiently, such as digital cameras, wireless keyboards, medical equipment, and portable gaming devices.

Equipped with advanced safety features, the IMREN AA battery includes overvoltage, overcurrent, overcharge, and overheat protection, enhancing its reliability and safety. These protections prevent potential damage to both the battery and the device it powers, ensuring longevity and optimal performance. Additionally, it boasts a low self-discharge rate, meaning it retains its charge for extended periods when not in use. Even after months of storage, the battery maintains a significant percentage of its initial charge, making it a convenient and dependable choice for both occasional and frequent users.

Manufactured by IMREN, a brand known for high-quality rechargeable batteries, the AA-2000 model features a standard AA size with dimensions of 15mm in diameter and 50mm in height. The battery has a pointed positive terminal, which ensures compatibility with a wide range of electronic devices that require standard AA batteries. The nominal capacity of 2000mAh guarantees long runtime, while the nominal voltage of 1.2V ensures it can efficiently replace standard alkaline batteries in various applications.
The charging process for the IMREN 2000mAh battery is optimized for efficiency and longevity. It utilizes a constant current, constant voltage (CCCV) charging method at 1.50A with a voltage of 4.20V ±0.05V and a cutoff at 150mA to protect against overcharging. With a charging time of approximately 2.5 to 3 hours, the battery quickly replenishes its energy reserves, making it a practical solution for users who require frequent battery replacements. The discharge rate is designed to be versatile, accommodating currents between 80mA (0.1ItA) and 400mA (0.5ItA), ensuring optimal compatibility with a variety of devices.

For durability and efficiency, the battery has an initial impedance of a maximum of 13mΩ, ensuring minimal resistance and high energy efficiency. It is also designed to perform reliably in a wide range of environmental conditions. The operating temperature range extends from 0°C to 45°C during charging and -20°C to 60°C during discharging, making it suitable for both indoor and outdoor use. The storage temperature range of -20°C to 45°C ensures safe and stable performance even when kept in non-climate-controlled environments, and the recommended storage humidity level of ≤75% RH helps maintain battery integrity over time.
