AI Overview
High-temperature lead-acid batteries are specialized VRLA (Valve Regulated Lead-Acid) or gel batteries designed to resist heat-induced degradation, often featuring advanced additives like carbon or specialized, heat-resistant plastic cases. These batteries are designed to survive up to 3x longer than standard VRLA units at
, making them ideal for high-temperature telecom, UPS, and solar applications. Key benefits include improved performance at
and above, reduced need for cooling, and increased life in extreme environments.
Key High-Temperature Lead-Acid Technologies
- Deka Fahrenheit HT7500ET (12vDC): Features THT heat-resistant plastic and a Helios additive to reduce float current and prevent thermal runaway.
- CSB XTV12800 / XPL4700 Series: Specialized AGM batteries for extreme temperatures, offering long-life in high-heat industrial settings.
- Vision Group HTB Series: Designed for outdoor cabinets, operating reliably from to.
- Canbat CHT Series: Designed for high-heat environments like the Arabian Gulf, with an 8-10 year service life at high temperatures.
Key Features of High-Temp Models
- Advanced Alloys: Special grid alloys (like TempX) reduce corrosion at high temperatures.
- Heat-Resistant Casing: Materials with high oxygen indices prevent case bulging.
- Catalyst Additives: Microcat catalysts lower float current, mitigating thermal buildup.
- Gel Electrolyte: Often used for better heat management than liquid acid (AGM).
