AG series button batteries are mainstream disposable alkaline miniature batteries with a standard round flat button shape, widely adopted in global consumer electronics. Marked with unified AG model codes including AG1, AG3, AG10, AG13 and more, these batteries feature a standard rated voltage of 1.5V, matching the universal voltage requirement of most low-power micro electronic equipment.
Classified as primary non-rechargeable batteries, AG button cells adopt mature alkaline chemical systems and fully sealed metal shell packaging. Different from rechargeable lithium batteries and Ni-MH batteries, they focus on stable long-term low-current discharge rather than cyclic charging performance. With ultra-small size, lightweight design and stable voltage output, AG button batteries have become the most cost-effective miniature power source for daily small electronics for decades.
Designed in mini button shape, AG batteries occupy extremely limited internal space of tiny electronic products. The overall diameter ranges from 5mm to 11mm, and the total weight of a single cell is less than 2 grams. Such a miniature dimension perfectly fits ultra-thin and mini electronic structures that ordinary cylindrical batteries cannot adapt to, meeting the miniaturization design trend of modern portable gadgets.
Equipped with high-purity alkaline electrolyte, AG button batteries maintain steady 1.5V constant voltage throughout the whole discharge cycle, without obvious voltage drop during long-term working. This stable power supply is critical for precision electronic devices such as quartz watches and electronic calculators, avoiding device shutdown or data error caused by fluctuating current.
All qualified AG button batteries adopt multi-layer sealed steel shell structure and anti-corrosion internal isolation design. They effectively prevent electrolyte leakage even under daily extrusion, slight vibration or normal temperature changes. Besides, modern mercury-free AG batteries comply with global RoHS environmental standards, with no explosion, combustion or other safety risks during normal use and storage, achieving high intrinsic safety for civilian scenarios.
AG series button cells own outstanding storage performance. With a yearly self-discharge rate lower than 5%, the batteries can retain over 90% of full capacity after 3 years of sealed storage. They support long-time standby placement without frequent replacement, which is ideal for devices that work intermittently or stay on standby for most of the time.
Benefiting from mature mass production technology, AG button batteries have low production cost and affordable retail price. Meanwhile, each AG model corresponds to unified international universal codes (such as AG13 matching LR44, AG3 matching LR41), realizing perfect compatibility with mainstream global electronic brands. No extra adapter or modification is needed for replacement, bringing great convenience for end users.

AG button batteries are non-rechargeable. Never charge them to avoid bulging, leakage or safety hazards.
Do not mix new and old batteries or different model batteries in one device, which will cause inconsistent current and shorten service life.
Keep batteries away from high temperature, humid environment and direct sunlight to slow down self-discharge.
Keep button batteries away from infants and pets to prevent accidental swallowing risks.
Dispose of waste batteries following local environmental regulations instead of random dumping.
With the booming development of miniaturized and portable electronic devices worldwide, the demand for low-power miniature batteries keeps growing steadily. Though emerging lithium button batteries occupy part of the high-end market, AG alkaline button batteries still maintain irreplaceable competitiveness thanks to their low price, universal compatibility and high safety performance.
In summary, AG series button batteries are reliable, eco-friendly and cost-effective miniature primary batteries. Delivering stable long-lasting micro power for countless tiny electronic devices, they remain an essential basic power component in daily life, industrial supporting and consumer electronics industries.
