Frequently asked questions
How do I read a battery code like CR2032?
The letters give the chemistry and shape (C = lithium, R = round), and the digits give the size: 20 mm diameter, 3.2 mm height. So a CR2025 is the same width but thinner, and a CR2450 is wider and thicker. Alkaline buttons use LR, silver-oxide use SR.
Are AG13, LR44 and 357 the same battery?
AG13 and LR44 are the exact same 1.5 V alkaline cell under different naming systems. 357 (SR44W) is the same size in silver-oxide: it fits the same devices and lasts longer with a steadier voltage, which is why watchmakers prefer it.
Can I use a battery with a different height?
Sometimes a thinner cell will physically fit with the help of the spring contact, but it is not recommended: contact pressure and runtime suffer, and some devices will not close properly. Match both diameter and height whenever possible.
⚠️ Keep away from children. Swallowed button batteries, especially 20 mm lithium coins, cause severe injury within hours. If a child swallows one, call the 24/7 National Battery Ingestion Hotline (US) at 800-498-8666 or poison control at 800-222-1222 immediately. What every parent should know.
