Description

JCB LR41 alkaline button cells deliver 1.5V output in a compact 7.9mm diameter coin format, supplied in a 10-pack for stocking spares. The LR41 designation (also sold as AG3, 392, SR41W equivalent in alkaline chemistry) fits watches, small calculators, laser pointers, key fobs, hearing aids, small LED torches, remote car keys and compact digital thermometers.

Each cell measures 7.9mm diameter by 3.6mm height, weighing approximately 2g, and uses alkaline manganese dioxide chemistry for stable voltage discharge across its service life. The cells are packaged in a blister strip with individual recesses, keeping them separated to prevent short-circuiting in storage. Typical shelf life is 3-5 years when stored at room temperature.

The JCB branding on the card indicates these cells are produced under JCB's licensing agreement with battery manufacturers. The alkaline chemistry provides higher capacity than cheaper zinc-air or silver oxide alternatives for the same LR41 form factor, though silver oxide cells (SR41) may offer longer life in high-drain devices. For most everyday electronics the alkaline version provides good value and reliable performance.

Frequently Asked

What devices use LR41 batteries?

LR41 cells are common in wristwatches, small calculators, laser pointers, key fobs, hearing aids, compact digital thermometers, remote car keys and small LED torches. The 7.9mm diameter and 3.6mm height make them one of the most widely used button cell formats.

Are LR41 and AG3 the same battery?

Yes. LR41 is the IEC designation, while AG3 is an alternative industry code for the same alkaline cell. Other equivalent codes include 392, LR736 and V3GA. They are all the same 7.9mm x 3.6mm alkaline button cell with 1.5V nominal voltage.

How long do LR41 alkaline batteries last?

Service life depends on the device and how often it operates. In a wristwatch with minimal backlight use, an LR41 may last 1-2 years. In a laser pointer or LED torch with frequent use, expect 3-6 months. Shelf life when stored unused is typically 3-5 years.

Can I use silver oxide SR41 instead of alkaline LR41?

SR41 silver oxide cells fit the same physical space and deliver 1.55V versus 1.5V, so they are compatible. Silver oxide cells hold voltage more consistently under load and may last longer in high-drain devices, but they cost more. For most everyday applications the alkaline LR41 works well.
