USB Fast Charge Lithium Battery AA 14500 Rechargeable 1665mWh Polymer Cobalt Battery

This USB fast charge lithium battery is a practical rechargeable alternative to standard AA alkaline cells, designed for devices that require steady power over extended periods. The built-in USB charging port eliminates the need for a separate charger, making it convenient for home, office, or travel use. With its constant 1.5V output and 1665mWh capacity, this battery is suitable for high-drain electronics such as digital cameras, wireless mice, smart locks, and portable gaming devices. The polymer cobalt lithium chemistry provides a stable energy source that can be recharged up to 1000 times, reducing the frequency of battery replacements and cutting down on waste.

Features and Construction

This battery is built around a polymer cobalt lithium core, which balances energy density with safety. It is housed in a standard AA-size casing with a silver green finish, ensuring compatibility with most AA battery compartments. The integrated USB port allows direct charging from any standard USB power source.

Material and Build

The battery uses polymer cobalt lithium chemistry, a type of rechargeable lithium-ion technology that offers a high energy-to-weight ratio. The casing is made from durable materials with a silver green colour, and the battery features a built-in micro-USB or USB-C port (specific connector type not specified) for charging. Safety circuits are integrated to monitor voltage and temperature.

Size and Practical Fit

This battery conforms to the AA/R6/5/14500 dimensions, meaning it is 14mm in diameter and 50mm in length. It fits directly into any device designed for AA batteries, though users should note that the voltage output is a constant 1.5V, which differs from the 3.7V typical of standard 14500 lithium cells. This makes it compatible with devices that require 1.5V input.

Uses and Placement

The constant 1.5V output and rechargeable nature make this battery ideal for devices that drain power quickly or run for long periods. Its USB charging capability adds convenience for users who want to avoid carrying spare batteries or a separate charger.

Event and Professional Use

For photographers, audio engineers, or event staff who rely on battery-powered equipment, this battery reduces downtime. A full charge takes under 90 minutes, and the 1665mWh capacity can power items like wireless microphones, flash units, or remote controls through a full event without replacement.

Everyday Home Use

In the home, these batteries work well in devices such as TV remotes, children’s toys, clocks, and cordless phones. The ability to recharge via USB means you can top up the battery overnight or during the day without hunting for a charger.

Benefits and Buying Value

The primary value of this battery lies in its long service life and safety protections. Being able to recharge up to 1000 times, it replaces hundreds of disposable batteries over its lifetime. The six built-in protection circuits help prevent common battery failures.

Reuse and Low Maintenance

With a rated life of 1000 recharge cycles, this battery significantly reduces the need for frequent purchases of single-use cells. The USB charging is straightforward and does not require special equipment. Operating within a temperature range of -20°C to 60°C, the battery can be used in varied environments.

Why Choose This Product

This battery stands out for its combination of USB direct charging, constant voltage output, and comprehensive safety features. It is available in packs of 2 or 4, offering flexibility based on your device needs. The polymer cobalt lithium construction provides a balance of capacity and recharge speed, making it a reliable power source for daily use.
