What you get

This pack contains ten AG4 alkaline coin cells. Each cell delivers 1.5 volts and a rated capacity of 20 milliamp_hours. They are suited for watches, calculators, thermometers, toys and similar low-drain devices.

Critical fit check

The batteries measure 6.8mm in diameter and 2.6mm thick. AG4 is a direct size match for LR626, SR626SW, 377 and 376 button cells. Verify your device requires these exact dimensions before ordering.

Thermals and power

Alkaline chemistry provides stable voltage at room temperature with negligible self-heating in normal use. The cells hold charge for up to two years in storage. They are non-rechargeable and must not be exposed to fire.

Questions about this item

What does the 1.5 volt rating mean once the cell is inside my watch?

It provides the standard operating voltage most small devices expect, so the watch or calculator runs at its designed speed and accuracy from the moment you install the cell.

Which battery codes does the AG4 alkaline replace in practice?

It directly replaces LR626, SR626SW, 377 and 376 cells because they share the same 6.8 millimetre diameter and 2.6 millimetre thickness, making it a drop-in alternative for most watches and small electronics.

What physical space does each cell need to fit?

Each button cell measures 6.8 millimetres across and 2.6 millimetres high, so the battery compartment must accept that exact diameter and thickness for a secure fit.
