Reliable Rechargeable Power for Critical Communication Devices
elxjar is committed to developing precision-engineered rechargeable battery solutions designed for devices that require dependable power availability and consistent electrical output. The brand emphasizes accurate voltage calibration, verified capacity ratings, and structural compatibility to ensure seamless integration with existing electronic systems. Rather than relying on exaggerated claims, elxjar focuses on real-world usability, stable discharge behavior, and repeatable performance across charging cycles. Each battery is engineered to support uninterrupted device operation in situations where dependable power continuity and predictable runtime are essential for maintaining communication functionality.
Stable High-Capacity Power for Handheld Radios
This rechargeable lithium-ion battery is designed to deliver steady 3.7V output for handheld radio systems that rely on internal rechargeable power sources. It is commonly used in weather alert and hand-crank radio devices where reliable energy storage supports continuous monitoring, signal reception, and auxiliary lighting or charging functions. The battery is built to align with the original form factor and connector layout used by compatible radio models, enabling straightforward installation.
This battery is intended only for radio systems designed around single-cell 3.7V lithium-ion battery architecture. It is not suitable for alkaline battery compartments, multi-cell battery packs, or devices designed for lower-voltage chemistries. For optimal performance, the battery should be fully charged before initial use, allowing the internal chemistry to stabilize and deliver accurate capacity during operation.

Key Product Features
Rechargeable Lithium-Ion Design with Consistent Output
This battery is rechargeable and engineered to support repeated charge and discharge cycles under normal operating conditions. The lithium-ion chemistry delivers stable voltage output throughout the discharge curve, supporting consistent radio performance over extended usage periods. Integrated protective circuitry helps regulate electrical behavior during charging and discharging to reduce the risk of abnormal conditions.
Before reviewing specifications, it is important to note that this battery should only be charged using charging systems designed for single-cell 3.7V lithium-ion batteries. The nominal voltage is 3.7V with a rated capacity of 2600mAh, resulting in a correctly calculated energy capacity of 9.62Wh. This configuration supports extended runtime while maintaining compatibility with compact radio designs.
The internal connector design allows direct installation when fitment and polarity match the radio interface.
Battery Specifications
Prior to first operational use, a full charging cycle is recommended to activate the internal chemistry and ensure accurate capacity output during use.
Electrical specifications include a nominal voltage of 3.7 volts and a rated capacity of 2600 milliampere-hours. The resulting energy output is 9.62 watt-hours, calculated by multiplying voltage and capacity to maintain consistency across all specifications. The battery is configured as a single-cell rechargeable unit with integrated protective circuitry.
Physical specifications include a compact rectangular form factor designed to fit securely within compatible radio battery compartments. The size and weight are balanced to provide sufficient energy storage without placing unnecessary stress on internal connectors or housing components.

Safety, Storage & FAQ
This battery incorporates internal circuitry designed to help manage charging and discharging behavior during normal operation. Users should avoid exposing the battery to excessive heat, moisture, or mechanical impact. Charging should only be performed using equipment designed for lithium-ion batteries, and connector orientation should be verified prior to installation.
For storage, the battery should be kept in a cool, dry environment away from direct sunlight. If stored for extended periods, maintaining a partial charge level can help preserve internal stability. Before first use, an extended initial charge, including an overnight charging period, is recommended to fully activate the battery chemistry.
Is this battery rechargeable
Yes, this is a rechargeable lithium-ion battery designed for repeated charging cycles.
How should the battery be charged for first use
A full initial charge is recommended before use to stabilize internal chemistry and capacity delivery.
