Hello, I notice that the cellphone batteries have 3 or 4 pinouts
[Positive - Temperature - ID - Negative]
I'm using this battery as a backup for arduino uno.
I would like to know how to read the temperature from the battery. Both, code and the connection if possible.
Battery info: 3.7V 1100mAh 4 pinouts
Thanks!
best way: disassemble the battery and find out what battery controller IC it uses, then find the datasheet for that, which will tell you how to read it.
easy way: stick a thermistor to the battery pack, then monitor the battery temp yourself.

It is a cellphone battery, I already open the battery and the "IC" does not have any number except for the +, TH, ID and - tags on the pinouts.
I previously was using a separate thermistor but since the "IC" already has a thermistor I would like to use that one.
I try to read the values with an arduino serial code and using an analog pin but the values are random... there is no pattern nor a fixed value that varies with the temperature changes.
any other suggestions?
Yes perhaps, some cell phone batteries used thermistors and Th. is a standard symbol notation for a thermistor... There are several sketches that are easily modified for that purpose, Google is your friend. If you can't fint it at first in the playground.

What is OEM of battery?
Is it brand name one or aftermarket one?
The picture of IC?
How many pin of IC?
How many wires from battery cell to protection board?
The picture of battery?
How many pin of battery, 4 or 3?
