Soshine 1.5V Li-Ion Rechargeable AA Battery User Manual

Introduction

Thank you for choosing Soshine 1.5V Li-Ion Rechargeable AA Batteries. These batteries are designed for long-lasting performance and convenience, featuring direct USB-C charging and a constant 1.5V output. This manual provides essential information for safe and efficient use, including setup, operation, maintenance, and troubleshooting.

The Soshine 1.5V Li-Ion rechargeable battery offers a non-constant voltage discharge curve, which is smoother and provides a longer discharge time compared to many other 1.5V lithium batteries. It also includes a unique low-battery alarm design to prevent sudden power loss.

Important Safety Instructions

WARNING: Failure to follow these instructions may result in fire, electric shock, or injury.

Do not overcharge or over-discharge the battery.
Do not use under extreme conditions, such as extreme temperatures, deep cycling, extreme overcharge, and over-discharge.
Do not reverse discharge the battery, as this will cause leakage, fire, and explosion.
Do not mix new batteries with half-used batteries when using, as this may result in over-discharge.
It is not allowed to put batteries in water.
Charge the battery out of reach of children.
Do not short-circuit the battery, as this will permanently damage the battery.
Do not disassemble or ignite the battery, as this may cause an explosion.
Do not use non-USB standard devices for charging, as this may cause overheating, leakage, or damage.
Please stop charging and remove the USB charging cable when the battery is fully charged. Charging the battery for a long time may cause danger.

Setup and Initial Charge

Before first use, ensure the battery's appearance is not damaged (no dents, bulges, or leakage). If any damage is present, do not use the battery.

A new battery will achieve optimal performance after 3-5 cycles of charge and discharge.

Charging Instructions:

Connect the provided 4-in-1 USB-C charging cable to the USB-C port on each battery.
Connect the other end of the USB-C charging cable to a 5V USB power source (e.g., computer, mobile power bank, car charger).
The LED indicator on the battery will flash green during charging.
Once fully charged, the LED indicator will turn solid green.
Disconnect the charging cable from the battery and power source.

Important Charging Notes:

The battery is forbidden to be charged with any charger other than a USB-C charging cable with an adaptor. Using a non-USB-C charger can cause the battery to explode.
When charging multiple batteries (e.g., 4 batteries), ensure your power source provides a current of 5V/2A or more. If the current is less than 2A, some batteries may stop charging.
Charge time will vary depending on the battery's capacity and current condition.

User Tips

Optimal Performance: For best results, allow new batteries to complete 3-5 full charge and discharge cycles.
Timely Recharging: Recharge batteries promptly after they are fully discharged to prolong their lifespan.
Check Compatibility: While these batteries provide a constant 1.5V, some sensitive devices designed specifically for alkaline or Ni-MH batteries might behave differently. Always check your device's manual for battery compatibility.
Use the Right Cable: Always use the provided USB-C charging cable or a compatible high-quality USB-C cable for charging.
Environmental Consideration: These Li-Ion batteries are designed for many cycles, reducing waste from disposable batteries. Please recycle them responsibly at the end of their life.

Warranty and Support

Period of Warranty:

The warranty period for Soshine batteries is half a year from the date of shipment. Soshine guarantees replacement for cells with defects proven to be due to manufacturing processes, not customer abuse or misuse.

The Chemical Reaction:

Batteries utilize a chemical reaction, and their performance will naturally deteriorate over time, even when stored unused. Usage conditions such as charge/discharge cycles, ambient temperature, and storage practices can affect battery life. If batteries can no longer maintain a charge for reasonable periods, it may be time to replace them.
