LR43 Batteries and Battery Types
So now you know the equivalent names, although they may not be exactly the same size. Typically LR43 for alkaline batteries and SR43 for silver-oxide batteries are the most commonly used two-digit codes. Knowing and comparing battery types will help you choose the right battery.
Alkaline Equivalent: LR43, AG12, LR1142, 386, 301, 186 Batteries
Battery labels for alkaline 11.6×4.2 mm batteries are usually seen on LR43, AG12, LR1142, 386, 301, and 186 batteries; however, certain labels are interchangeable. For example, some manufacturers like Cotchear AG12 coin battery also use the AG12, 386, 301, and 186 numbers to label silver-oxide batteries.
A typical capacity of approximately 100 milliamp hours is achieved by using lithium-ion batteries, such as the LR43 or the LR1142. These batteries have a nominal voltage of 1.5 volts, a cutoff voltage of 1.0 volts, and a base capacity of 1.5 milliamp hours is achieved using lithium-ion batteries. PKCELL LR1142 button cell battery is one of them. It is important to note that the capacity of powered devices is frequently dependent on the cutoff voltage and drain current.
Among that alkaline batteries, Maxell LR43 1.5v alkaline button batteries are low-cost, high-reliability power sources for toys, flashlights, and other electronic devices that can withstand voltage drops over extended periods. If you want to see another similar kind of 1.5V alkaline button or coin cell battery, you can look in glimpse LR1130 Battery Equivalents.
Why We Recommend:
- As a battery’s life progresses, the voltage drops;
- Consume less energy and last longer;
- Anti-Leak Protection to prevent damage to devices;
- Extra Power Formula.
Silver Oxide Equivalent: SR43W, SR43, SR43SW, 386, 301, 186, AG12, SG12, SR1142, SR1142SW Batteries
Batteries with a silver-oxide 11.6×4.2 mm size are known as SR43W, SR43, SR43SW, 386, 301, 186, AG12, SG12, SR1142, and SR1142SW, but the SR43, SR1142, and SR43S models are by far the most prevalent (W). Examine the battery’s description and chemistry when buying if any of the following numbers appear on the label: 186, 301, or 386.
Energizer Silver Oxide Batteries have an output of 130 milliamp-hours (mAh) and have a nominal voltage of 1.55 V, with an operating cutoff voltage of 1.22 V. These batteries are available in various capacities, including “high-drain” and “low-drain” models, which are labelled differently by some manufacturers. For example, “Battery capacity is 130mAh when discharged over 6.81k (224.6A) at 20°C to 1.2v using Duracell - 303/357/76 Silver Oxide Button Battery which is an extreme-drain SR43.
Loopacell 386/301 TS Silver Oxide batteries are frequently utilized to power fragile and sensitive electronic devices. More crucially, silver-oxide cells have a larger steady voltage, more capacity and longer shelf life than alkaline batteries. However, they do cost slightly more.
Why We Recommend:
- Costly but durable;
- Can tolerate high current loads;
- Ensures that voltage is maintained while in operation;
- Very high energy-to-weight ratio;
- Higher life expectancy.
Zinc Air and Mercury-Oxide Equivalent: AC41E, PR43, or 7001Z
Zinc-air 11.6×4.2 mm batteries are rare in production. They were marketed under the names AC41E, PR43, and 7001Z and were used in hearing aids.
