Equivalent Batteries
Several companies use other names that may be interchanged with AG1 batteries.
General common names: SG1, LR60, LR821, and SR621, SR621SW are common compatible batteries.
Brand names:  Energizer and Duracell will use names of 164, 364.

Difference Between Alkaline and Silver Oxide Versions
Most brand name batteries such as Energizer and Maxell will sell only silver oxide chemistry batteries in this size.  Silver oxide batteries will last longer as their capacity is about 20 mAh, 53% more. Most electronics can use both generic alkaline AG1 batteries or SR621SW silver oxide batteries.

Saving Money
If you do not mind switching batteries more often, generic alkaline batteries are cheaper to buy. You can find 10 packs of AG1 batteries at a great deal for around $2 shipped.  If a couple dollars is not that much money to you, then try silver oxide batteries for longer life.
