Lr66 Battery
Overview
Product sourcing insights & recommendations
The LR66 battery (commonly known as AG4) is a high-volume alkaline button cell primarily used in low-cost consumer electronics. While physically identical to the silver oxide SR626SW, it offers a significantly lower unit price at the cost of voltage stability and shelf life.
Key Insights
- Price Gap: Wholesale LR66 batteries are priced as low as $0.01–$0.04/piece, whereas silver oxide counterparts cost $0.15–$0.55/piece.
- Market Shift: There is a growing trend of consumers avoiding LR66 for watches due to "voltage drop" issues that cause inaccurate timekeeping, favoring the more stable silver oxide chemistry.
- Top Applications: LR66 remains dominant in toys, LED novelties, and simple calculators, while SR626SW is the industry standard for precision quartz watches and medical devices.
