What the pack contains

The Tenergy LR41 alkaline button cell pack supplies 20 cells at 1.5 V each. They suit owners of digital thermometers, wrist watches, laser pointers, small toys and similar low-drain portable electronics. The 7.9 mm diameter by 3.3 mm height format matches the common AG3 size.

Cross-reference list and leakage protection

The packaging lists dozens of equivalent codes including 392, 384, 736, SR41 and SR736 variants, so the cells replace silver-oxide types in existing devices. An anti-leak construction and low internal resistance aim to keep contacts clean during extended use.

Shelf life and limits

Stored correctly the batteries hold charge for up to 5 years thanks to a printed date code. They are not designed for high-current applications such as camera flashes or motor-driven toys where voltage would sag quickly. Buyers needing rechargeable chemistry or higher capacity cells should look elsewhere.

Questions about this item

How long will these LR41 cells hold their charge in storage?

The alkaline chemistry is rated for up to 5 years shelf life when stored properly, and each cell carries a date code for tracking.

What stops them powering a laser pointer or thermometer continuously?

Internal resistance rises as the 1.5 V alkaline chemistry depletes, so voltage sags under sustained drain and the device cuts out.

Do the 20 cells generate noticeable heat or noise during all-day use in a watch?

No — the tiny 7.9 × 7.9 × 3.3 mm alkaline buttons produce no audible noise and negligible heat in low-drain applications.
