Coin-cell pack for small electronics

This pack contains ten AG4 alkaline button cells rated at 1.5 volts and 25 milliamp-hours each. They suit watches, calculators, laser pointers, remote controls and similar low-drain devices that require a 6.8 millimetre diameter cell. The batteries are supplied new and ready for immediate use. Buyers who need rechargeable cells or higher-capacity chemistries should look elsewhere.

Shelf stability and leak resistance

Alkaline chemistry with a manganese-dioxide cathode and zinc anode delivers a stable 1.55 volt output and very low self-discharge for long storage life. A U-shaped sealed steel shell with nickel-plated stainless steel outer layer prevents electrolyte leakage and resists short circuits. No active cooling or thermal management is involved in normal operation.

Cross-reference compatibility

The cell carries multiple industry designations including LR626, LR66, SR626, SR626SW, 377, 376, 177, 565, GP377, V377, L626, G4, GA4, D377, 377A and SR66. Matching any of these codes on the device or original battery confirms correct fit. Devices requiring a different voltage or physical size will not accept this cell.

Questions about this item

How do I insert the 6.8 mm AG4 cell the right way round?

Match the flat positive side to the + mark in the device; the 1.5 V alkaline chemistry will not work if reversed.

When will the 10-pack need replacing in a device drawing steady current?

Each cell holds 25 mAh; divide that by the load in milliamps to estimate hours before voltage drops.

What voltage sag appears first during continuous drain on these alkaline button cells?

The 1.55 V open-circuit level falls toward 1.5 V and then lower as internal resistance rises with depletion.
