Tenergy LR44 1.5V Alkaline 10 Pack

This pack contains ten LR44 alkaline button cells rated at 1.5 volts each. They suit owners of watches, calculators, laser pointers, small thermometers and similar low-drain portable electronics. The cells are manufactured by Tenergy and carry part number 40013.

Direct replacement for LR44 AG13 SR44 357 303

Each cell matches the 11.6 mm diameter and 5.4 mm height common to the LR44, AG13, SR44, 357, 303 and numerous other designations listed in the specifications. The alkaline chemistry delivers 1.5 V nominal voltage, making the pack a drop-in substitute for any device specifying those sizes.

Low self-discharge with anti-leak construction

Tenergy states the cells feature low internal resistance and an improved anti-leak design for up to three years of shelf life. The non-toxic alkaline chemistry reduces corrosion risk during storage, so the batteries remain ready for intermittent use in medical devices, toys or small flashlights.

Questions about this item

What does the 1.5 V rating mean when the cell is inside a watch?

It supplies the steady voltage the watch movement expects, so the timekeeping circuit runs at its designed speed without voltage sag.

Which battery standard does the LR44 follow, and what does that limit?

The cell matches the LR44/AG13 alkaline button‑cell standard, fixing its diameter at 11.6 mm, height at 5.4 mm and chemistry at 1.5 V alkaline.

Will the 11.6 mm × 5.4 mm size fit my device’s battery compartment?

Yes, if the compartment is built for LR44, AG13, 357, SR44 or any of the listed equivalents, the 11.6 mm diameter and 5.4 mm thickness will seat correctly.
