8 Cautions
1. Cautions of batteries’ operation
The batteries must be careful of proceed the operation for it’s soft package.
Aluminum packing materials
The aluminum packing material was easily damaged by the sharp edge part, such as nickel-tabs.
forbid to use the sharp part touching the battery;
should cleaning working condition, avoiding the sharp edge part existence;
forbid to pierce the battery with nail and other sharp items;
the battery was forbidden with metal, such as necklace, hairpin etc in transportation and storage.
Sealed edge
Sealing edge is very easily damaged and don’t bend it.
The Al interlayer of package has good electric performance. It’s forbidden to connect with exterior
component for preventing short-circuits.
Folding edge
The folding edge is formed in batteries’ processes and passed all hermetic tests, don’t open or
deform it. The Al interlayer of package has good electric performance. It’s forbidden to
connect with exterior component for preventing short-circuits.
Tabs
The batteries’ tabs are not so stubborn especially for aluminum tabs. Don’t bend tabs.
Mechanical shock
Don’t fall, hit, bent the batteries’ body.
Short-circuit
Short-circuit is strictly prohibited. It should damage batteries badly.

Standard Test Environment for polymer lithium-ion batteries
Environment temperature: 20±5
Humidity: 45-85%
3. Cautions of charge & discharge
charge
Charging current should be lower than values that recommend below. Higher current and voltage
charging may cause damage to cell electrical, mechanical, safety performance and could lead heat
generation or leakage.
Batteries charger should charging with constant current and constant voltage mode;
Charging current should be lower than (or equal to )1C5A;
Temperature 0 40 is preferred when charging;
Charging voltage must be lower than 4.25V.

discharge
Discharging current must be lower than (or equal to )2C5A;
Temperature 0 60 is preferred when discharging;
Discharging voltage must not be lower than 2.75V.
over-discharge
It should be noted that the cell would be at an over-discharge state by its self-discharge. In order to
prevent over-discharge, the cell shall be charged periodically to keeping voltage between 3.6-3.9V.
Over-discharge may cause loss of cell performance. It should be noted that the cell would not discharge
till voltage lower than 2.5V.
4.Storage of polymer lithium-ion batteries
The environment of long-time storage:
Temperature: 20±5 ;
Humidity: 45-85%;
Batteries were 40 60% charged.
5.Transportation of polymer lithium-ion batteries
The batteries should transportation with 10 50% charged states.
6.Others
Please note cautions below to prevent cells’ leakage, heat generation and explosion.
Prohibition of disassembly cells;
Prohibition of cells immersion into liquid such as water or seawater;
Prohibition of dumping cells into fire;
Prohibition of using damaged cells. The cells with a smell of electrolyte or leakage must be placed away
from fire to avoid firing.
In case of electrolyte leakage contact with skin, eye, physicians shall flush the electrolyte immediately
with fresh water and medical advise is to be sought.
9. Notice of Designing Battery Pack
9.1 Pack design
Battery pack should have sufficient strength and battery should be protected from mechanical shock. No
sharp edge components should be inside the pack contain the battery.
9.2 PCM design
The overcharge threshold voltage should not be exceed 4.25V.
The over-discharge threshold voltage should not be lower than 2.75V.
The PCM should have short protection function built inside.
9.3 Tab connection
Ultrasonic welding or spot welding is recommended to connect battery with PCM or other parts.
If apply manual solder method to connect tab with PCM, the notice below is very important to ensure battery
performance.
The electric iron should be temperature controlled and ESD safe;
Soldering temperature should not exceed 350 ;
Soldering time should not be longer than 3s, keep battery tab cold down before next soldering;
Soldering times should not exceed 5 times;
Directly heat cell body is strictly prohibited, battery may be damaged by heat above approx. 100 .

9.4 Cell fixing
The battery should be fixed to the battery pack by its large surface area. No cell movement in the battery
pack should be allowed.
9.5 Cells replacement
The cell replacement should be done by professional people.
Prohibit short-circuit between cells’ Al package and exterior component.
