Reliable Power for Outdoor and Everyday Use
The Soshine 9V USB Rechargeable Li-ion Battery is a protected lithium-ion battery with a 500mAh capacity and a nominal voltage of 7.4V, designed for low-drain devices like smoke alarms, wireless microphones, electric guitars, and medical devices. It features two charging methods: a micro-USB port with a 1A charging current (cable not included) and direct charging via the positive and negative poles using a compatible charger. The battery includes a 4-LED power display to indicate charge status, with a red light during charging and green when complete. It offers overcharge, over-discharge, and short-circuit protection, ensuring safety, and a shelf life of up to 4 years due to low self-discharge. The battery can be recharged up to 500 times, but tests suggest its capacity may be closer to 400mAh under certain conditions.
Durable and Compact Design
The Soshine 9V USB Rechargeable Li-ion Battery is built with a durable lithium-ion cell, offering a lightweight and compact design for easy integration into devices used in outdoor settings. It measures 48.5mm in length, 26.4mm in width, and 15.4mm in height, weighing 27g, making it slightly smaller than a standard alkaline 9V battery. The battery includes a micro-USB charging port with an LED indicator, but the lack of a charging cable in the package means users must supply their own. Its protective circuit board (PCB) ensures safety, but the battery should be stored carefully to avoid short-circuiting.
