Features & Benefits

Reliability in all environments

  • Simplify your network design and save money on cooling costs regardless of the region or conditions. Our engineers designed TEL-HT to operate in extreme temperatures ranging from -40°F to 160°F (-40°C to 71°C).

Longest service life

  • We designed TEL High Temperature for quality, battery service life, and value. Our patented Pure Lead (MSE) technology and optimized grid alloys minimize corrosion and provide long-lasting performance. This longevity can lead to approximately 20% in cost savings.* C&D backs up TEL-HT high temp AGM batteries with an industry-leading warranty.**

Supports sustainability

  • Low float currents allow TEL-HT batteries to operate at higher temperatures for longer, which lowers energy demand. They are 98% recyclable and manufactured with up to 80% recycled materials. C&D creates high quality products and process improvements to minimize our environmental footprint.

Maintenance efficiency

  • True Front Access terminals minimize failure points and save maintenance time, without sacrificing reliability. AGM technology eliminates periodic water maintenance. The TEL-HT's rugged polypropylene case protects all internal battery components.
