Description

The JCB LR44 is a 1.5V alkaline button cell battery supplied in a 2-pack, designed for small electronic devices requiring compact, reliable power. The LR44 cell size (also known as AG13, A76, or 357 in some regions) measures 11.6mm diameter by 5.4mm height and delivers consistent voltage across the discharge curve, making it suitable for watches, calculators, car key fobs, fitness trackers, small toys, medical devices, laser pointers, and digital thermometers.

The alkaline chemistry provides longer shelf life and higher capacity than zinc-carbon equivalents, with typical storage life of 3-5 years when kept at room temperature. The two-cell pack suits households and workshops needing spare batteries for devices that use LR44 cells singly or in pairs, with each cell delivering approximately 150-200mAh capacity depending on load conditions.

JCB's Super Alkaline range uses an improved electrolyte formulation designed to reduce internal resistance and maintain stable voltage output under moderate drain conditions. The cells operate across a temperature range of -10°C to 60°C, though performance drops at temperature extremes. The blister pack protects the cells from short-circuit during storage and transport, with each cell individually sealed until use.

Frequently Asked

What devices use LR44 batteries?

LR44 button cells power watches, calculators, car key fobs, fitness trackers, small LED torches, laser pointers, digital thermometers, glucometers, and many children's toys. Devices typically use one or two cells depending on required voltage.

Are LR44 batteries the same as AG13 or A76?

Yes. LR44, AG13, A76, 357, and SR44 (silver oxide version) are all 11.6mm × 5.4mm button cells with 1.5V nominal voltage. The LR44 designation refers specifically to the alkaline chemistry variant, which is the most common and cost-effective type for everyday devices.

How long do these batteries last?

Shelf life is typically 3-5 years when stored at room temperature. In-device lifespan depends on current draw — a watch may run 1-2 years on a single LR44, while a high-drain device like an LED torch may deplete the cell in days or weeks of active use.

Can I use rechargeable LR44 equivalents?

Rechargeable LR44-size cells exist but deliver 1.2V rather than 1.5V, which may cause issues in devices designed for alkaline voltage. Most users replace LR44 cells with new alkaline cells rather than recharging due to the small capacity and low cost of disposable versions.
