What is the capacity of the SR44 battery?
- Battery capacity of SR44 is 150 mAh.
Are LR44s the same as a CR2032 battery?
- No CR2032 battery has lithium chemistry and a larger size; we cannot replace the CR2032 with the LR44 battery.
What’s LR44 Advantage?
- The LR44 battery has high power and a longer working life. Its voltage is 1.5 volts and compact dimensions with alkaline chemistry. It works for high and low temperatures to get power through the reaction between manganese dioxide and zinc. The LR44 battery is lower cost than the silver oxide battery. But has huge capacity and a longer working life Its uses are calculators, electronic toys, and small cameras.
