Physically the same size as CR2450, LIR2450 can be used as a rechargeable replacement to CR2450 in most cases. This little battery has little over 100 mA/Hour capacity, with nominal 3.6 V output. LIR2450 battery is perfect for powering a small project.

    Since I could not find a good charger for it, I made one.
