LR 44 Battery Button Mini

Product description:

LR44 Button cell battery – 1.5 V, Ø11.6 × 5.4 mm, 110-150 mAh

At least as popular as AA or AAA batteries in small electronic devices. Available in many flavors and brands and easy to find in stores. Used in everything from watches and remote controls to small tools and toys. Silver oxide (357/SR44) alternatives are recommended if you want longer, more stable operation – especially in precision and medical devices.

Basic specifications

Type: Alkaline button cell (disposable) with zinc-manganese dioxide chemistry

Voltage: Nominal 1.5 V

Capacity: Typically between 110-150 mAh depending on brand and load

Dimensions: Ø 11.6 mm × 5.4 mm (diameter × thickness) – according to IEC standard (±0.2 mm)

Weight: Around 1.9-2.1 g

Compatibility and alternatives

The LR44 battery is sold under many names – often with the same physical size and voltage:

Alkaline equivalents: AG13, A76, LR1154, G13, L1154, V13GA, etc.

Silver oxide versions: SR44, 357, 303 – 1.55 V, better voltage stability and longer durability

LR44 alternatives are used in watches, toys, remote controls, cameras, medical devices, thermometers and calculators

Performance and durability

Lifetime depends on the load:

Low consumption, e.g. watches: up to 6-12 months

Medium consumption, e.g. small electronic devices: typically 3-6 months

If the battery is used in LED lights or darkened toys: only 1-3 months

Shelf life: 2-5 years for alkaline, longer (7-10 years) for silver oxide

Temperature range: Can typically be used at -10 °C to +60 °C

Technical fields and usage tips

Stability: Silver oxide versions (1.55V) provide more constant voltage and longer performance; alkaline versions have greater voltage drop over time.

Avoid leakage and swelling: Storage in dry conditions is recommended. Several users report that alkaline batteries can expand/bulge or leak
