Testing Quality



1)Standard Test Conditions: If no otherwise requirement, room temperature (RT) is 25 °C ±2 °C, and all tests are conducted at 25 °C±2 °C, 15~90 %RH and atmospheric pressure of 86 kPa~ 106 kPa.

2)Standard Charging Method: In standard test conditions, charge the cell at a constant current of 0.5C until the voltage reaches 3.65 V, then charge it at a constant voltage of 3.65 V until the current decreases 0.05 C and placed for 1 h.

3)Standard Discharging Method: In standard test conditions, discharge the cell at a constant current of 0.5C until the voltage reaches 2.0V.



Storage and Transportation

Based on the character of cell, proper environment for transportation of pack need to be created to protect the battery.

1)During transportation, 5%~50% SOC must be kept to ensure that short circuit, appearance of liquid in the battery or immersion of battery in liquid never occur.

2)Cell should be kept at 0°C-40°C in warehouse where it’s dry, clean and well-ventilated.

3)During loading of battery, attention must be paid against dropping, turning over and serious stacking.

Comment & FAQ

1. How should I pay? What modes of payment do you accept?

A: T/T, PayPal, Western Union & Trading Assurance acceptable.

2. Is sample order acceptable?

A: Yes, for most of the batteries, sample orders for testing quality is reasonable and acceptable.

3. How can you prove that your cells are 100% original?

A: We can show you the original pack list and other related documents.

4. What is your lead time if I placed an order?

A: For all products in stock, our lead time is within 3 working days after payment received. For these that we don't stock for the moment such as customized battery packs, the lead time is around 7-10 days.

5. What is your warranty?

A: We guarantee the quality before the item is shipped. You can enjoy 30-day free refund, 4-month free replacement, and lifetime maintenance service from the date of delivery. Any damages caused by improper use are not covered by our warranty.

Precautions and Safety Instructions

In order to prevent the battery leakage, getting hot and explosion, please pay attention to preventing measures as following:


1)Never throw the battery into water. Store it under dry, shady circumstance when not use.

2)Never misidentify the positive and negative terminals.

3)Never connect the positive and negative terminals of battery with metal to prevent short-circuiting.

4)Never ship or store the battery together with metal.

5)Never knock, throw or trample the battery.

6)Never cut through the battery with nail or other edge tool.


1)Never use or store the battery under the over-high temperature. Otherwise it will lead to battery over-heating, which might lose some function and reduce life, even getting fire. The proposed temperature for long-term storage is 10~35°C.

2)Never throw the battery into fire or heating machine to avoid fire, explosion and environment pollution; scrap battery should be returned to the supplier and handled by the recycle station.

3)Never use the battery under strong static electronic and magnetic field, otherwise it will destroy the protecting device.

4)Never knead eyes if leakage electrolyte gets into eyes. Wash eyes by water and seek medical advice ASAP.

5)If battery emit peculiar smell, over-heating, distortion or appear any unconventionality during using, storage or charging process, please stop using and take it out of the device.

6)Never cut the battery in socket directly, please use the stated charger when charging.

7)Check the voltage of battery and relevant connectors before using. Do not use until everything turns out to be normal.

8)Prior to charging, fully check the insulativity, physical condition and ageing status. The pack voltage must not be less than the discharge cut-off voltage, if not, it needs to be labeled. The user should contact our Customer Service Department. It can’t be charged until repaired by our staff.

9)The battery should be stored in 5%~50% SOC. It needs to be charged once again if out of use for as long as half a year.

10)Clean the dirty electrode with a clean dry cloth if any contamination appears, otherwise poor contact or operation failure may occur.
