Rechargeable 3V lithium coin cells that eliminate battery replacement in OEM designs with integral charging circuits.
Uniross ML Lithium-Aluminium rechargeable coin cells provide a direct rechargeable alternative to standard CR primary cells in the same footprint. Rated for up to 600 cycles at 10% DOD, ML cells are engineered for embedded systems, industrial instrumentation, and IoT devices where a primary coin cell would require periodic replacement — eliminating the maintenance overhead and field service cost that comes with primary cell depletion in deployed products.
Key Benefits of Uniross ML Rechargeable Coin Cells
Up to 600 charge-discharge cycles — 600 cycles at 10% DOD; cells deployed at one cycle per day deliver over 1.6 years of daily cycling before reaching rated end-of-life — significantly longer for less frequent cycling regimes typical of backup and low-drain IoT applications.
Eliminates battery replacement — rechargeable coin cells in OEM products with integral charging circuits remove the field service cost and maintenance scheduling associated with primary cell depletion across deployed device fleets.
Direct CR footprint replacement — ML cells are dimensionally identical to their CR equivalents (ML2032 = 20.0×3.2mm); enables rechargeable upgrade without PCB or housing redesign for any system already designed for a 20mm or 24mm coin cell socket.
Stable 3V output across every cycle — consistent nominal voltage across the full 600-cycle service life; suitable for RTC circuits, voltage supervisors, and microcontrollers that require stable supply throughout the rechargeable battery’s lifespan.
-20°C to +60°C operating range — cycle count and capacity retention verified across the full industrial temperature range; suitable for outdoor infrastructure, transportation, and industrial control environments.
Available Models & Typical Applications
ML1220 / ML1225 — 12.5mm rechargeable family for slim wearables, compact access tokens, and miniature IoT nodes with integral energy harvesting or USB charging.
ML2016 / ML2020 / ML2032 — 20mm rechargeable family; direct rechargeable replacements for CR2016, CR2020, and CR2032 in CMOS/RTC backup, electronic shelf labels, and embedded IoT systems. ML2032 delivers 65 mAh with the highest cycle rating in the 20mm range.
ML2430 — 24.5mm rechargeable cell for medical telemetry, industrial data loggers, and smart metering applications requiring higher capacity in a rechargeable coin cell format.
