Uniross CR2032T HT Lithium Coin Cell Battery | 3V 220mAh High Temperature

Model No: CR2032T

The Uniross CR2032T HT is the flagship of the 20mm HT family — 220 mAh at a stable 3V with 5 mA continuous and 15 mA pulse ratings in the world’s most widely specified coin cell footprint. The “T” designation marks a fundamental upgrade over the standard CR2032: heat-resistant electrolyte, a reinforced stainless steel shell, and an advanced sealing ring extend the operating range to -30°C to +80°C, directly addressing the failure modes that disqualify standard CR2032 cells from automotive under-hood, outdoor smart metering, and high-ambient industrial applications. A direct drop-in replacement for standard CR2032 in any existing housing or PCB layout.

Product Features

  • -30°C to +80°C — the defining HT upgrade — heat-resistant electrolyte prevents swelling, leakage, and capacity loss at the elevated temperatures that cause standard CR2032 cells to fail in automotive engine bays, outdoor metering, and industrial enclosures
  • 220 mAh — maximum capacity in the 20mm HT family — the full electrode depth of the 3.2mm profile maximises runtime in the most common coin cell housing footprint
  • 5 mA continuous / 15 mA pulse — supports TPMS sensor bursts, RKE challenge-response, BLE advertising, and E-call module activation in high-temperature automotive and industrial environments
  • Direct drop-in for standard CR2032 — identical 20mm × 3.2mm dimensions and 3V output; no PCB or housing modification required when upgrading from standard to HT specification
  • 7-year shelf life — supports automotive OEM programmes and infrastructure deployments with extended service intervals and temperature-variable storage
