Some repair shops and distributors, due to the lack of professional purchasing guidance, fail to monitor storage temperature and humidity after purchasing batteries and cells in bulk, and also fail to charge the batteries in time. These wrong storage methods may result in battery failure after being stored for more than 3 months, such as poor voltage, battery bulging, etc., which will cause unnecessary losses.

Today, REWA shares battery storage and precautions, along with ways to recharge them, to help you store batteries and cells correctly, thereby save operating costs.

Why Should Batteries Be Stored Properly?

Lithium batteries are commonly used in phones, tablets, and other electronic devices. There are strict requirements for the storage of lithium batteries in terms of temperature and humidity. In terms of battery charging and discharging, temperature has the greatest influence among all environmental factors.

Lithium batteries' electrochemical reactions are related to ambient temperature. Firstly, if the temperature is too low, the battery will lock and there will be no voltage output. Battery lock means that when battery power drops to an extremely low state, the battery will automatically lock to protect battery health and user safety. Secondly, excessive temperatures will accelerate the battery's self-discharge rate, which is not conducive to long-term storage.

Additionally, lithium batteries cannot be left in a low-power state for an extended period of time, which will result in a reduction in battery life, and it is irreversible. For this reason, it is necessary to maintain the battery's performance by checking its voltage every three months as well as performing charge and discharge cycles if necessary.

How to Store Batteries Correctly?

If distributors or repair shops purchase batteries and cells in bulk, we recommend that they build a dedicated warehouse for storing batteries and cells in the following manner:

How to Recharge Batteries and Cells?

To maintain battery performance, REWA recommends testing battery voltage every 3 months. If the voltage is too low, the battery needs recharge.

Recharge Steps:

1. Use Multimeter to check batteries' voltage.

2. Use Battery Charge Activation Board and DC Power Supply to recharge batteries.

Guidelines:

1. Please store batteries according to the supplier's product instructions to ensure a safe voltage level. Different batteries may have different standard voltage levels.

2. When the battery voltage drops below the safe threshold, it is imperative to recharge it promptly and safely.

3. Note that deeply discharged batteries subjected to high-current charging may overheat, swelling, or damage. Therefore, for safe recharging, it is recommended to combine trickle charging with regular charging.

Please be aware that recharge operations require expertise. If needed, please contact REWA for customized recharge solutions. REWA provides both individual and bulk recharge solutions for batteries and battery cells.

Summary

The batteries and cells used in electronic devices, including mobile phones, tablets, smart watches, etc., are consumables with a limited lifespan. They can usually be charged and discharged 300-500 times. Thus, mastering the optimal storage method is equivalent to extending the battery's life and ensuring that your investment will yield a greater return.
