Why choose alkaline AG4 button cells?
Alkaline AG4 cells are a cost-effective choice for devices with moderate or occasional energy needs. They are convenient to store as spares and are easy to fit into compact battery compartments. The Uniross AG4 LR626 option in this category is intended for customers who want a straightforward replacement battery without confusion over multiple reference numbers.
- Compact size: ideal for thin and lightweight electronic devices.
- Multiple equivalent codes: useful when your old battery is marked LR626, 377, 177 or AG4.
- Reliable alkaline chemistry: suitable for many everyday low-drain applications.
- Easy replacement: no special charger is required because these are primary, non-rechargeable cells.
If your device manual specifies silver oxide chemistry for high-precision watches or medical instruments, follow the manufacturer recommendation. For many common gadgets, however, an alkaline AG4 battery offers a practical balance between availability and value.
Tips for selecting and using AG4 LR626 batteries
- Remove the old battery carefully and read the exact code printed on the case.
- Match the replacement with AG4, LR626, 377 or 177 if your device lists these as compatible references.
- Insert the new cell with the plus and minus sides aligned exactly as shown in the battery compartment.
- Keep spare button batteries in their packaging until needed, away from moisture, heat and metal objects.
- Always store small batteries out of reach of children and pets.
For best results, replace all cells in a device at the same time when it uses more than one button battery. Mixing old and new batteries can reduce performance and may cause leakage.
