C&D's Tel High Temperature (HT) is our longest lasting high-performance VRLA battery for Telecom applications that can endure extreme conditions that saves you on CAPEX/OPEX costs by deferring replacements and reducing operational expenses.

Tel-HT batteries are Reliable in All Environments with the widest operating temperatures in the market which can simplify your network design and save you money on cooling costs.
Anti-Corrosion Grid Alloy uniquely inhibits corrosion, substantially improving battery life by 40% and minimizing capacity loss over time.
Proprietary Paste is engineered to last 40% longer than traditional paste with low float currents and reduced water loss.
Supports Sustainability in your network as these batteries are 98% recyclable, made with up to 80% of recycled materials, and require low float current which can help lower utility costs.
C&D True Front Access Terminal design significantly reduces cabinet installation time, periodic maintenance, and failure points.

Simplified Installation & Maintenance

C&D's Tel HT batteries have several distinct advantages using patented “True Front Access” terminals.

True Front Access terminals have fewer connection points which can decrease installation and maintenance timeframes
True Front Access terminals minimize power loss inside inside the battery for better performance

C&D Ohmic Ring allows direct access to True Front Access terminals for accurate maintenance measurements
True Front Access terminals minimize connections and points of failure
