CE RoHS MSDS UN38.3
make sure good quality
6 protection for safe use
Details determine success
Use copper foil material which purchased
from a public company, with good flexibility,
high conductive, excellent heat exchange
The precision mold which degree of precision is
0.001 mm, can touch the phone connector
perfectly, Gold Plating touch the spot , low
internal impedance, never oxidation.
Battery Protection Board
Protection board use 4 layers copper
（low internal resistance). Each
piece protection board pass more than 10
testing process to make sure stable quality

Why choose our battery
Full automatic production line
Small Manufacturers, handiwork
Automatic production line avoid the quality problems
by hand, high efficiency with good quality
Bad environment, manual operation, it is easy to appear
mistake if by full manual operation, low efficiency, bad quality
AYJ Battery Cell
after 650 times cycle life
after 100 times cycle life
The surface of the battery cell is still smooth, thickness
only increase 0.1mm, it can be used normally
There will be particle from the battery cell inside, thickness
increase 0.2mm, easily caught fire and explode the screen
AYJ welding machine
￥300,000 Laser welding machine
￥2000 Foot-type welding machine
We use big brand Automatic laser welding machine,
computer control to make sure welding precision,
fastness, high efficiency with good quality
Foot-type welding machine, melted nickel by pressure,
large current ,high frequency, high temperature
High frequency is easy to breakdown the separator between
positive pole and negative pole.
Broken the protection board IC to led fire or explosion
Pressure by foot is not stable, easy to crushing damage the
after 3 times bending
Common FPC after 3 times bending
FPC problem is the most often problem during use.
AYJ FPC use copper foil material which purchased
from public company, good flexibility, high conductive,
excellent heat exchange material.
XRM FPC can bear about 5KG tension（pulling force
Greatly reduces FPC break off problems.
Common FPC Easy to break off ,bad flexibility , low
conductive, high internal resistance（FPC high resistance will
cause temperature rise when FPC overcurrent, even fire）
