Standing for high rate, the HR series is designed to provide power backup for smaller output applications like those found in personal or business power backup applications. The HR family is VRLA-AGM construction, which means the battery is maintenance free, no need to add water and able to be installed in multiple physical orientations without affecting service life.

HRL series, standing for high-rate long life, takes our HR and UPS series and expands upon its exceptional performance across various high-power backup power requirements.

Standing for uninterruptible power supply, the UPS series is the first in a lineup of premium quality offerings from CSB for the UPS power application market. UPS series are specifically designed for high power discharge applications, like those found in data centers of today. Our UPS series uses the latest wafer-thin plate technology combined with special proprietary formula, all to provide optimum high-rate performance.

XHRL series is our premium offering in high-rate power backup applications meant for EMEA markets, taking HR, UPS, and HRL designs even further to provide extended service life and even higher power density in both front and top terminal designs.

More than just a high-performance battery, Calor XHT-FT stands alone as the problem-solver to help data center operators meet sustainability goals with reduced cooling costs, extend battery replacement life, and perform at extreme power discharge requirements. XHT-FT can deliver maximum power within 30 seconds to ensure connectivity stays intact in extreme elevated temperature environments. Our innovative In-Case Formation (ICF) process combined with proprietary catalyst introduction and PC-ABS plastics, XHT enhances charging efficiency and provides consistent battery capacity over the available service life at elevated temperatures. XHT also has an optional front and top terminal connection design for ease of installation and maintenance. With an industry-leading warranty to provide peace of mind, XHT from CSB is the trusted battery provider for all mission critical power needs in all environments.

XPL series is our premium offering in high-rate power backup applications meant for N. America, S. America, and Asia-Pacific markets, taking HR, UPS, and HRL designs even further to provide extended service life and even higher power density in top terminal designs.

XPL-FT series is our premium offering in high-rate power backup with a front terminal design for even higher power density in shorter duration, up to 30 seconds. XPL-FT uses a unique separator design combined with pure lead construction. XPL-FT batteries are meant for data center applications in N. America, S. America, and Asia-Pacific markets, taking HR, UPS, and HRL designs even further to provide extended service life and even higher power density in front terminal designs.
