hello there .. i have wondered if i could use a Phone battery for modding , it has 3.7v and 1100mAh ?
Cellphone batteries to the best of my knowledge are UNPROTECTED the cellphone has a circuit that keeps them from over charging or over discharging, use with great caution. Learn the difference between protected and unprotected batteries before use. Your Family and Neighbors will thank You!It Is not protected!
You must be very careful
I checked mine and it IS protected. Amazon.com: Cell Phone Battery for Samsung D820 Li-Ion, Lithium Ion Technology, 100% fits, properly matching Batteries: Cell Phones & Service
Surely it is likely that most are as they are consumer items that do get carried around outside the phone.
To be sure though, check whether yours is protected before use.
kin that is an aftermarket, my OEM batteries are unprotected it is cheaper for the manufacturer to puth the circuit in th edevice than spec protected batteries.
How can Corporate greed and short sightedness surprise anyone in this day and age?As spares might get shorted when carried aound, it makes sense to put the protection in the battery itself. Surprised that any consumer changed batteries would not be.
