LR43 Battery, 1.5 V Alkaline Button Cell Battery and LR43 Equivalents

The LR43 battery is a non-rechargeable disposable primary battery. The LR43 Battery is a 1.5V alkaline button cell battery that is compact and cost-effective. This alkaline button cell battery gives your smartphone long battery life and good continuous power. The alkaline battery is a less expensive alternative to silver oxide batteries, yet it still has a high capacity and a long life.

LR43 Battery is ideal for watches, alarm transmitters, children's books, calculators, sugar level detectors, and many other toys and small electronics.

• Excellent cost performance

High-cost performance has been achieved owing to the use of manganese dioxide as a cathode material.

• Excellent stable discharge  and high-drain pulse discharge characteristics

Stable voltage output  is available during the high-drain pulse discharge, 

• Excellent leakage resistance 

Murata-unique sealing structure, coupled with special sealing-material treatment, has helped accomplish the excellent leakage resistance, 

• RoHS Directive / European Directives

This product does not contain Mercury (Hg), Cadmium (Cd), or Lead (Pb), and conforms to EC regulation values. (Directive 2006/66/EC, 2013/56/EU)

The battery pack is excluded from the RoHS directive. (DIRECTIVE 2011/65/EU OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment)

• Medical

• Insulin pumps

• Thermometers

• Drug delivery systems

• Electronic calculator 

• Toys

LR43 Discharge Characteristics

SR43, AG12, LR1142, 386, 301, and 186 are all LR43  battery counterparts. LR44 is the same size as silver oxide button cells as SR43W, SR43SW, 386, 301, 186, AG12, SG12, but has different chemistry. There is no mercury in this product.

The following is the LR43 Equivalents Batteries Comparison Chart.

LR43 VS LR44

LR43 has the same voltage, diameter, and mA-hr as LR44, but it is 1.2mm thinner. If you can put the batteries into the battery compartment (same number, polarity, etc.) and make excellent contact, your gadget should operate. With LR43, the gadget will last less time than with LR44.

LR43 Dimensions

Murata is a global leader in the design, manufacture, and supply of advanced electronic materials, leading-edge electronic components, and multi-functional, high-density modules. Murata innovations can be found in a wide range of applications from mobile phones to home appliances, and automotive applications to energy management systems and healthcare devices.
