Toy & Laser Pointer Battery Equivalents
Toys usually specify alkaline chemistry and tolerate voltage sag. Match the size code on the compartment lid — AG13/LR44 is frequently confused with the much smaller AG3/LR41.
Selection notes
- Never mix old and new cells in series packs.
- AG13 ≠ AG3 — diameter differs by nearly 4 mm.
- For high-drain motor toys, fresh alkaline or NiMH AA/AAA outperform tired button cells.

LR44 is one of the most searched button cells worldwide — an 11.6 × 5.4 mm, 1.5V alkaline cell also sold as AG13, A76, 76A, or LR1154. Silver oxide SR44/357 fits the same holder and is the better upgrade for watches and meters.
AG13 is one of the most searched alkaline button labels online. It is the same 11.6 × 5.4 mm, 1.5V cell as LR44, A76, and 76A — not a different chemistry.
A76 is Energizer's equivalent name for the standard LR44/AG13 alkaline button cell. If your device tray says A76, any quality LR44 alkaline of 11.6 × 5.4 mm will fit.
LR41 (AG3/L736) is a compact 7.9 × 3.6 mm alkaline button cell — much smaller than LR44.
AG3 is the alkaline equivalent label for LR41 button cells.
AA (LR6) is the world's most common cylindrical battery size at 14.5 × 50.5 mm.
AAA (LR03) is the compact sibling of AA at 10.5 × 44.5 mm.
LR1130 (AG10/L1131) is an 11.6 × 3.0 mm alkaline cell — thinner than LR44 in the same diameter. Shoppers often search L1131 or AG10 for the same family.
Frequently Asked Questions
Can kids' toys use silver oxide watch batteries?
Physically often yes, but silver oxide costs more and is unnecessary for intermittent toy loads. Alkaline is the usual choice.
