Equivalent Batteries
Several companies use other names that may be interchanged with AG3 batteries.
General common names: SG3, LR41, LR736, and SR736 are common compatible batteries.
Brand names: Energizer and Duracell will use names of 192, 384, or 392.
How to Get Longer Life
For electronics where you want longer life, then substitute with a silver oxide battery instead of using the alkaline version. SG3, and SR736 are such batteries with silver oxide chemistry and have a typical capacity of 45 mAh. The higher capacity equals to about 29% longer life.
Saving Money
Since button cell batteries will have the same capacity, a cheaper generic battery will perform just as well as a more expensive brand name battery. Also, you can easily find AG3 batteries sold in packs of 10 cheaper than a 2 to 3 pack of the brand names. They normally have a shelf life of 2 to 4 years.
