20 Pack Alkaline Button Cells

This card contains twenty AG8 alkaline button cells rated at 1.5 volts. They replace LR1120, LR55, 391 and all listed equivalents. The pack suits owners of watches, calculators, cameras, toys and car security remotes. Buyers who need lithium chemistry or rechargeable cells should look elsewhere.

Thermals Noise Power

Alkaline button cells generate no measurable heat and run silently in normal use. Each cell delivers 1.5 volts until depletion, with no active cooling or power draw concerns. The chemistry is stable across typical indoor temperatures for the devices listed.

Build Fit

The cells fit any device specifying AG8, LR1120, LR55, 391 or the equivalent numbers 280-30, 609, 1120, 1121, SR1120W and others shown. They serve as CMOS memory backup batteries in computer equipment. No holder, charger or special tooling is required.

Questions about this item

How do I install the AG8 button cell so the device powers on?

Match the positive side marked on the 1.5 volt alkaline cell to the + symbol in the battery compartment, then press the 1120 size cell firmly until it clicks into place.

When will the LR55 alkaline cell need replacing in a CMOS memory backup role?

The 1.5 volt alkaline chemistry typically lasts one to two years in a low-drain CMOS backup before voltage drops below the level the motherboard can hold settings.

What is the first sign the AG8 cell is failing during continuous use in a laser pointer?

The beam dims noticeably as the alkaline voltage sags under sustained current draw, signalling the 1.5 volt cell is depleted.
