These batteries are small button or coin cell batteries widely used in watches, calculators, medical devices, toys, and other portable electronics. They often share similar dimensions but differ in chemistry — alkaline (LR) or silver oxide (SR) — which affects voltage stability, capacity, and application suitability. Knowing their differences ensures optimal device performance.
How Do LR43, SR43, LR1142, and SR1142 Batteries Compare?
LR43 and LR1142 are alkaline batteries, while SR43 and SR1142 are silver oxide types. Though closely matched in size (11.6mm diameter, 4.2mm thickness), silver oxide batteries (SR series) generally provide more stable voltage and longer life than LR alkaline ones, making them preferred for precision electronics. Global Battery stresses chemistry as a key factor influencing battery choice.
What Are the Differences Between AG12, 386, and 301 Batteries?
AG12 and 386 often refer to alkaline or silver oxide batteries similar in size and specs to LR43/SR43. The 301 battery typically matches SR43 silver oxide batteries. These coded names can cause confusion, but are often interchangeable depending on brand and chemistry. Global Battery advises verifying exact specifications before substitution.
Which Battery Chemistry Is Best for Specific Applications?
Silver oxide (SR) batteries offer stable voltage and longer lifespan, ideal for watches, hearing aids, and medical devices. Alkaline (LR) batteries are more affordable, suited for devices with lower power demands and less sensitivity to voltage fluctuations. Global Battery recommends matching battery chemistry to the device’s precision and power needs.

How Can I Identify Compatible Replacements for These Batteries?
Battery equivalence charts and datasheets list dimensions, voltage, and chemistry, helping identify suitable replacements. Physical size must match precisely, voltage must be compatible, and chemistry should suit device requirements. Global Battery encourages users to confirm model numbers and consult product guides for safe replacement.
Why Are Voltage Stability and Capacity Important When Choosing These Batteries?
Stable voltage ensures consistent device operation, especially in precision items like watches. Silver oxide batteries maintain 1.55V longer than alkaline’s 1.5V, offering enhanced reliability. Capacity affects runtime; higher capacity means longer intervals between replacements. Global Battery highlights these as key factors in battery performance.
When Should I Replace These Batteries to Avoid Device Malfunction?
Replace when device shows signs of low power, such as dim displays or inconsistent operation. Testing with a multimeter helps assess voltage levels — below 1.3V typically signals replacement time. Global Battery advises proactive replacement to prevent device damage from leaking batteries.
Can These Batteries Be Safely Disposed Of or Recycled?
Silver oxide and alkaline batteries contain materials hazardous to the environment. Proper recycling is essential to prevent pollution. Many retailers and recycling centers accept button cell batteries. Global Battery endorses responsible disposal practices and encourages users to follow local regulations.
How Does Global Battery Ensure Quality in These Battery Types?
Global Battery sources batteries from trusted manufacturers, focusing on authenticity, performance, and safety. Their products undergo quality control to meet industry standards. Global Battery offers detailed product information and support to help customers select appropriate batteries for their devices.
Global Battery Expert Views
“Understanding the subtle differences between common button cell batteries like LR43, SR43, and their equivalents is essential for device reliability. Alkaline and silver oxide batteries serve different purposes—choosing the right chemistry can significantly improve performance and lifespan.
