Varta lithium photo battery CR1/3N 3V 170mAh (single blister)

The VARTA CR1/3N is a high-performance 3-volt lithium button cell, developed for professional and demanding applications with high energy requirements in the smallest of spaces. Based on lithium manganese dioxide technology (Li-MnO2), it offers exceptionally high cell voltage and capacity in a very compact design. Supplied in protective single blister packaging, it is the ideal energy source for a wide range of cameras, medical devices and security technology.

Highlights at a glance

• High energy density: Maximum energy and high 3-volt voltage in a compact button cell.
• Powerful performance: Reliably delivers high currents for demanding electronic devices.
• Wide temperature range: Reliable performance in extreme conditions from -30 °C to +70 °C.
• Long shelf life: Extremely low self-discharge ensures years of readiness for use.
• Secure packaging: The protective blister ensures freshness and performance right up to use.

Reliable energy for precision applications

The VARTA CR1/3N is the preferred energy source for a wide range of devices where performance and miniaturisation are crucial. Its main field of application is in analogue and digital photography to power cameras and exposure meters. It is also ideal for use in security sensors, electronic dog collars, sighting systems, medical devices (e.g. blood glucose meters) and as a backup battery in professional electronics.

Superior lithium manganese dioxide technology

The lithium manganese dioxide technology (Li-MnO2) enables the high nominal voltage of 3 volts, which often replaces the use of two 1.5-volt silver oxide cells and thus reduces space and complexity in device design. The technology guarantees stable voltage over most of the battery’s life, an extremely low self-discharge rate of less than 1% per year at room temperature, and excellent performance even at low temperatures.

Developed for maximum reliability

The CR1/3N was developed for the highest possible reliability and safety. Its robust construction and high VARTA quality protect high-value devices from damage caused by leakage. The protective single blister ensures that the battery retains its full performance until use and is protected against short-circuiting and environmental influences.
 

Characteristics

FAQs about the VARTA lithium battery CR1/3N

What is the main advantage of this lithium battery?

The key advantage is the high voltage of 3 volts in a single, very compact cell. In many devices it can replace two stacked 1.5-volt silver oxide batteries (such as SR44), resulting in more reliable power supply and easier battery change.

Is this battery rechargeable?

No. This is a primary lithium battery. It must not be attempted to recharge it under any circumstances. Attempts to charge are extremely dangerous and can result in fire or explosion.

What is a 3-volt button cell of this size needed for?

It is required for compact devices with a relatively high energy requirement. Examples include the illumination of camera viewfinders, active electronics in exposure meters, transmitter modules in dog collars or the power supply for laser sights.

Is this battery compatible with 2L76 or DL1/3N?

Yes, the terms CR1/3N, 2L76 and DL1/3N are used by different manufacturers for the same battery type and are interchangeable.

How should this battery be disposed of?

Batteries must not be disposed of with household waste. Please return the empty battery to the designated collection points in shops or municipal recycling centres to ensure environmentally friendly recycling.
