CR2335 3V Lithium Coin Cell: The High-Capacity Energy Anchor for Industrial Automation & Smart Utilities

In industrial control rooms and smart utility grids, data loss isn’t just an error—it’s an expensive operational disaster. When main power grids fluctuate, your hardware relies on a silent backbone to safeguard system memory, maintain Real-Time Clocks (RTC), and preserve programming logic.

The CR2335 3V Lithium Manganese Dioxide (Li/MnO2) battery is engineered specifically for these high-stakes environments. Merging a massive 300mAh capacity into a robust Φ23.0×3.5mm form factor, this primary cell provides the heavy-duty power reservoir required to keep industrial machinery and remote utility meters completely autonomous for up to a decade.

Why Hardware Engineers Specify Our CR2335 for Demanding Grid Nodes?

• Ultra-High Density Energy Reserve (300mAh): Maximized within a 3.5mm profile, this cell offers one of the highest capacities in the 23mm diameter class. It translates directly to extended field life, minimizing expensive battery replacement cycles in remote or sealed environments.
•  Uncompromising Autonomy (<2% Annual Self-Discharge): Utilizing hyper-pure lithium chemistry and an advanced hermetic sealing matrix, it loses less than 2% of its charge per year at room temperature. Your backup power remains fully charged even after years of AC mains grid operation.
•  Industrial Thermal Armor (-20°C to 70°C): From freezing outdoor sub-stations to high-heat factory floors near heavy industrial machinery, the cell chemistry is stabilized to maintain a flat, dependable 3V discharge curve without voltage sagging.
•  Engineered Mechanical Fit (Φ23.0×3.0mm to 3.5mm): The precise 3.5mm height allows for high structural stability and resistance to industrial vibrations, ensuring constant contact alignment on complex PCB layouts.

Core B2B Application Ecosystems

The CR2335 3V battery functions as the ultimate long-term energy vault for non-volatile RAM (NVRAM) and microchip clock backup across specialized B2B sectors:

1. Smart Utility Meters & Instrumentation: Powers the internal processors of smart electricity meters, gas flow flowmeters, and digital water meters, ensuring continuous data logging and wireless telemetry transmission even during absolute grid failures.
2. Industrial Control Systems & PLCs: Acts as the critical memory bridge for Programmable Logic Controllers (PLCs), CNC machinery, and robotic automation hubs, preserving coordinate settings and operational firmware during maintenance shutdowns.
3. Automotive & Heavy Equipment Diagnostics: Safeguards localized fault-code memory and tracking configurations in rugged fleet management modules and embedded industrial data loggers.

Frequently Asked Questions (FAQ)

Can a CR2335 replace a standard CR2032 battery? No. While both output 3V, they are physically and capacity-wise vastly different. The CR2335 is wider (23mm vs 20mm) and thicker (3.5mm vs 3.2mm). Crucially, the CR2335 provides 300mAh of capacity compared to the typical 220mAh of a CR2032, offering nearly 36% more operational lifetime for heavy-duty industrial control systems.

How does the <2% self-discharge rate benefit smart meters? Smart meters are built to stay in the field for 10 to 15 years, mostly drawing power from the main utility grid line. The internal CR2335 battery remains completely passive during this time. A self-discharge rate of less than 2% per year ensures that the battery does not waste its energy while idle, leaving full capacity intact for emergency power outages.

Do you supply the CR2335 with pre-welded solder pins for automated assembly lines? Yes. We specialize in B2B supply chains. We offer custom terminal processing services including vertical through-hole pins, horizontal SMT solder tabs, and custom wire lead connectors engineered to feed directly into your automated pick-and-place surface mount assembly lines.
