What makes Ultracell's UFT series different from other VRLA batteries?

The UFT series uses a front-terminal layout, with both terminals accessible from the front of the case rather than the top. This makes installation, monitoring, and maintenance significantly easier in rack cabinets and enclosures, since batteries can be connected, tested, and replaced without needing to pull them out or access from above; a common requirement in telecoms and infrastructure systems.

Where are UFT front-terminal batteries typically used?

UFT batteries are used in telecommunications networks, utilities, renewable systems, and cabinet-based backup installations; anywhere batteries are rack-mounted or installed in enclosed cabinets, where front access for connection, monitoring, and replacement is essential.

Why choose Ultracell's UFT series over other front-terminal batteries?

The UFT series is tested to IEC 60896, the international standard for stationary lead-acid batteries, and holds VdS certification, an approval widely required for alarm and security-system applications. It's also manufactured under ISO 9001-certified quality management, giving a verifiable basis for consistency rather than a general quality claim.
