Li-polymer rechargeable battery LP155050 3.7v 300mah thin lithium
battery 155050 for smart card
This is a tiny rechargeable Lithium-ion polymer battery that fits
perfectly behind the Processor board to power your projects.
The battery has a capacity of 300mAh at 3.7V, the voltage can range
from 4.2V when fully charged to 3.0V when completely discharged.
Lithium polymer battery usually consists of several identical
parallel secondary cells to increase the discharge current, or
several battery packs in series to increase the available voltage.
As we all know, today this new type of lithium polymer batteries
are mainly used in portable devices, radio controlled devices,
personal electronics, smart wearable devices, Bluetooth
headset/speakers, GPS tracker, E-book, laptops, mobile phones,
digital cameras, digital camcorders, and gaming types of equipment…

Standard Test Conditions:
Test should be conducted with new batteries within one week after
shipment from our factory
and the cells shall not be cycled more than five times before the
test.
Unless otherwise specified, test and measurement shall be done
under temperature of 20±5℃
and relative humidity of 45~85%.
If it is judged that the test results are not affected by such
conditions, the tests may be
conducted at temperature 15~30℃ and humidity 25~85%RH.
Appearance
There shall be no such defect as flaw, crack, rust, leakage, which
may adversely affect
commercial value of battery.
