Core Engineering Advantages & B2B Benefits

1. Superior Energy-to-Volume Ratio

The CR1/3N yields 170mAh of capacity at 3V in a package roughly the size of two stacked button cells. This unique design saves valuable real estate on dense multi-layered boards while providing stable operational runways for microprocessors.

2. 10-Year Operational Lifespan (≤2% Self-Discharge)

Constructed with a highly stable lithium metal anode and advanced hermetic glass-to-metal sealing, the cell limits internal chemical degradation to under 2% annually. For devices that spend years in storage or standby mode, this guarantees immediate power deployment without passivation issues.

3. Sub-Zero to High-Heat Thermal Window (-40°C to +70°C)

The battery’s specialized organic electrolyte is structurally modified to resist freezing and performance degradation at -40 °C, while remaining completely leak-proof and electrochemically stable at up to +70 °C.

Veelgestelde vragen

Q1: Can a single CR1/3N replace two LR44 batteries?

A: Yes, in many applications. A single CR1/3N matches the physical dimensions of two stacked LR44 (or SR44) batteries and delivers a matching 3V output. However, because the CR1/3N utilizes Lithium Manganese chemistry rather than Alkaline or Silver Oxide, it offers superior capacity retention at low temperatures, a flatter discharge curve, and a significantly longer shelf life.

Q2: Is the CR1/3N battery rechargeable?

A: No. The CR1/3N is a primary (single-use) lithium battery. It cannot be safely recharged. Attempting to charge this cell can rupture the internal hermetic seal, leading to electrolyte leakage, internal short circuits, or thermal runaway.

Q3: Why is the ≤2% self-discharge rate critical for memory backup and smart meters?

A: Industrial smart meters and memory backup circuits spend the vast majority of their lifecycles in ultra-low micro-amp sleep modes. If a battery has a high self-discharge rate, its energy wastes away internally. A rate of ≤2% ensures that almost the entire nominal capacity of 170mAh is saved for actual device operations over a span of up to a decade.
