Temperature-qualified 3V lithium coin cells engineered for industrial and automotive environments where standard CR cells cannot be specified.
Uniross CR Lithium Manganese Dioxide HT Type coin cells are built for deployment where elevated ambient temperatures, wide thermal cycling, or outdoor exposure disqualify standard lithium primary cells. The “T” designation marks a fundamental change in cell construction: heat-resistant electrolyte chemistry, a reinforced stainless steel shell, and an advanced sealing ring extend the operating temperature range to -30°C to +80°C — well beyond the -20°C to +60°C ceiling of standard CR cells — preventing the electrolyte breakdown, leakage, and premature capacity loss that occur in high-temperature environments.
Key Benefits of Uniross CR HT Type Batteries
-30°C to +80°C operating range — the defining capability of the HT range; heat-resistant electrolyte and advanced sealing prevent swelling, leakage, and capacity loss at the elevated temperatures that cause standard CR cells to fail in automotive, outdoor, and high-ambient industrial environments.
Heat-resistant electrolyte — engineered to maintain stable electrochemical performance at +80°C; eliminates the capacity degradation and internal pressure build-up that compromise standard lithium coin cells in high-temperature deployments.
Reinforced stainless steel shell — provides structural integrity and vibration resistance for automotive under-hood, industrial plant, and heavy-machinery environments subject to mechanical stress and thermal expansion.
Advanced sealing ring — leak-proof construction qualified for humid, dusty, and chemically aggressive industrial atmospheres where standard coin cell seals are insufficient.
7-year shelf life — low self-discharge in an HT-qualified cell; supports long-lifecycle device programmes and MRO stock holding in temperature-variable storage environments.
Broadest HT range available — 20 models from CR1216T to CR3832T; a single qualified HT supply base covers every standard coin cell footprint used in temperature-demanding OEM designs.
