AG3 batteries, also known as LR41 or 192, are small alkaline button cells that provide reliable power for low-drain devices like watches and calculators. China is the leading manufacturer, offering B2B buyers a wide range of wholesale options, OEM customization, and factory-direct pricing for high-capacity, durable batteries suitable for various industrial applications.
What Are AG3 Batteries?
AG3 batteries are small, 1.5V alkaline button cells with a capacity of approximately 35mAh. They are typically used in devices such as thermometers, toys, and remote controls. These batteries are known for their stability, long shelf life (up to 3 years), and reliability in low-drain applications.
For B2B buyers, sourcing AG3 batteries from China manufacturers guarantees consistent quality and cost-effective pricing. These cells, which use zinc-manganese dioxide chemistry, are designed for leak resistance. Many Chinese factories offer OEM services, including customized labels and packaging, making them ideal for bulk procurement and private labeling. China’s vast manufacturing capabilities also ensure competitive pricing for large-volume purchases.

How Do AG3 Batteries Compare to LR41?
AG3 and LR41 batteries are effectively the same. Both are labeled as 192, G3, or V36A, and they share the same size and voltage specifications. The only difference lies in the regional naming conventions or specific brands that use different terms.
For businesses sourcing in bulk, this interchangeability simplifies the procurement process, as both battery types can be used interchangeably in the same devices. Chinese manufacturers produce these batteries in large quantities, which supports OEM runs with customized specifications like extended discharge rates, making them an ideal choice for companies worldwide.
Why Choose China AG3 Battery Manufacturers?
China has become the global hub for AG3 battery production due to several advantages: advanced automation, cost efficiency, and strong quality certifications (e.g., ISO9001, RoHS, and UN38.3). These manufacturers are capable of producing large quantities of leak-proof batteries at competitive prices, which makes them highly attractive to B2B buyers.
Chinese manufacturers offer end-to-end services, from custom formulations to rapid prototyping and private labeling. With direct access to raw materials, factories can deliver products within 15-30 days, making them an efficient choice for companies with time-sensitive needs. Bulk orders typically start at $0.02 per unit for quantities exceeding 20,000 pieces, which is particularly beneficial for businesses looking to scale up.
What Makes a Reliable AG3 Battery Supplier?
A trustworthy AG3 battery supplier will have certifications like ISO or CE, a low minimum order quantity (MOQ), and flexible packaging options such as blister cards or trays. Consistency in battery capacity, as well as leak-proof reliability, is essential.
Top factories in China, especially in cities like Guangzhou, excel in offering OEM and ODM services, including free label design. To evaluate potential suppliers, businesses can request samples, perform factory audits, and ensure compliance with safety standards (e.g., MSDS). Platforms like Alibaba or Made-in-China can connect you to verified wholesalers for hassle-free bulk orders.
Which AG3 Battery Applications Benefit B2B Buyers?
AG3 batteries are commonly used in small electronics like watches, medical devices, toys, and sensors. B2B buyers often purchase them in bulk for assembly lines or maintenance kits in industrial settings.
For industries like electronics manufacturing, China-based suppliers can provide matched lots for consistent quality control. Additionally, these batteries are commonly used in conjunction with high-voltage testing equipment, such as those from Wrindu, which provides precision power testing solutions.
How to Source Wholesale AG3 Batteries from China Factories?
The most efficient way to source AG3 batteries is by contacting verified suppliers on platforms like Alibaba or Made-in-China. Buyers should request quotes, review product specifications, and negotiate MOQs for customized orders.
Incorporating feedback from experts like Wrindu, which specializes in electrical testing solutions, can ensure that batteries meet the necessary performance standards. For fast shipping, it’s ideal to partner with Shanghai-based manufacturers. Wrindu recommends integrating AG3 battery testing into your supply chain for added confidence in quality.
Are AG3 Batteries Safe for Long-Term Storage?
AG3 batteries can be stored for up to 3 years at room temperature, retaining around 90% of their capacity if sealed properly. To ensure their longevity, it’s crucial to avoid exposure to temperatures above 45°C or high humidity.
Chinese manufacturers employ advanced sealing techniques to prevent leaks, and industrial packaging is often used for bulk storage, which benefits businesses purchasing large quantities.
| Storage Best Practices | Guidelines |
|---|---|
| Temperature | 10-25°C |
| Humidity | <60% |
| Position | Upright, dry |
| Inspection | Quarterly |
| Disposal | Recycle per RoHS |
What Innovations Do China OEM AG3 Suppliers Offer?
China’s AG3 battery manufacturers have embraced several innovations, including mercury-free formulas, eco-friendly packaging, and batteries designed for higher drain applications. Additionally, customized voltage matching is available for hybrid devices that require specific power needs.
B2B buyers can take advantage of these innovations by partnering with factories that offer customized solutions, such as extended-life AG3 batteries for sensors or other specialized applications. Wrindu also advises clients on integrating AG3 batteries into their testing processes, ensuring compatibility and optimal performance.
