AG13 and LR44 are interchangeable names for 3V lithium button cells used in small electronics like calculators, watches, and medical devices. These batteries offer stable voltage, long shelf life (5-10 years), and compact size (11.6mm diameter x 5.4mm height). A 100-pack provides bulk savings for frequent users. Always verify device compatibility and store in cool, dry conditions.

What Environmental Impact Do Button Cells Have?
While mercury-free since 1996, AG13/LR44 still contain 1-2% zinc and manganese. Recycling through EPA-certified programs recovers 88% materials. Modern recycling facilities use hydrometallurgical processes to separate components, achieving 95% zinc recovery efficiency. Consumers should note that improper disposal of 100 batteries equals contaminating 60,000 liters of water. Many municipalities now offer free drop-off locations specifically for button cell recycling.
“Bulk AG13/LR44 purchases require careful inventory management,” says Dr. Elena Torres, battery technologist. “These cells gradually discharge even in storage. For critical medical devices, rotate stock quarterly and test random samples with a voltmeter.”
FAQs
- Can AG13 replace LR44 permanently?
- Yes – they’re identical in specs. Some devices specify one model due to regional branding.
- Why do bulk batteries expire faster?
- Improper storage accelerates discharge. Keep sealed in OEM packaging until needed.
