Some frequently ask questions about LR621 battery equivalent 

Are LR621 Battery Equivalent and 364 interchangeable?

Alkaline AG1 and LR621 Battery Equivalent are the same size (6.8 mm in diameter and 2.1 mm in height) and voltage (1.5V) as the 364 and SR621SW batteries. Little-drain electronics with little power requirements, such as remote controls, tiny toys, and simple electrical equipment, frequently use these batteries.

Is it possible to substitute SR621 for LR621?

Another comparable is the AG1 battery, which is usually sold under the alkaline chemistry label. AG1 (also known as LR621) cells are the same size as SR621SW cells, but they have a shorter lifespan and a slightly lower voltage of 1.5V.

Are LR621 and LR626 interchangeable?

Chemical Makeup: Both batteries are silver oxide and alkaline. LR621 is the basic AG1, while LR626 is the AG4 equivalent. SR621SW and SR626SW are their respective silver oxide versions. Voltage: Using various chemistries, both battery types offer a nominal voltage of 1.5 volts.

Is it possible to substitute SR621 for LR621?

Another comparable is the AG1 battery, which is usually sold under the alkaline chemistry label. AG1 (also known as LR621) cells are the same size as SR621SW, but they have a shorter lifespan and a slightly lower voltage of 1.5V.
