Description

The Energizer LR54/189 is a 1.5V alkaline button cell battery sold in packs of two. The LR54 designation (also sold as 189, AG10, LR1130 and 389 depending on the manufacturer) refers to an 11.6mm diameter, 3.1mm height button cell that fits calculators, digital thermometers, glucose meters, car key fobs, laser pointers, small LED torches and compact remote controls.

These batteries use alkaline chemistry rather than silver oxide or lithium, which makes them more affordable for devices that drain power slowly over months or years rather than in high-current bursts. The 1.5V nominal voltage remains stable across most of the discharge curve, meaning devices continue to function reliably until the battery is nearly depleted. Energizer rates the LR54 at approximately 40-50mAh capacity depending on the load profile.

The batteries are packaged in a sealed blister that keeps them fresh until opened. Energizer incorporates anti-leak construction in the cell casing to reduce the risk of electrolyte leakage during storage or after depletion. Each cell measures 11.6mm across and 3.1mm tall, matching the LR1130/AG10 footprint used in most button cell compartments marked for this size.

Frequently Asked

What devices use LR54 batteries?

LR54 button cells are commonly found in calculators, digital thermometers, glucose meters, car key fobs, laser pointers, small LED torches and compact remote controls. The LR54 is also sold under the designations 189, AG10, LR1130 and 389 depending on the manufacturer.

How long do LR54 alkaline batteries last?

Shelf life is approximately 3-5 years when stored in cool, dry conditions. In-use life depends on the device's current draw — a calculator or key fob may run for 1-2 years on a single cell, while a device with an LED backlight or continuous operation will deplete the battery faster.

Are these rechargeable?

No. LR54 alkaline button cells are single-use and should be disposed of responsibly once depleted. Attempting to recharge alkaline cells can cause leakage or rupture.

What's the difference between LR54 and SR1130 batteries?

LR54 (alkaline) and SR1130 (silver oxide) are the same physical size but use different chemistries. Silver oxide cells provide more stable voltage and higher capacity but cost more. Alkaline LR54 cells are sufficient for low-drain devices like calculators and key fobs.
