What makes a Ritar HT different from a standard AGM?

Its internal alloy is formulated to tolerate continuous temperatures of 35-50 °C without a drastic loss of service life, whereas in a standard AGM sustained heat noticeably accelerates ageing.

Where does a high-temperature battery make sense?

In unconditioned telecom huts and shelters, outdoor cabinets in the sun, hot plant rooms and, in general, any installation in southern Europe or Africa where the ambient regularly exceeds 30-35 °C.

Are they suitable for a UPS?

Yes. They are stationary VRLA batteries designed for float service in UPS and backup systems, with the advantage of preserving their service life in hot environments.

Do they need maintenance?

No. They are valve-regulated sealed AGM batteries: no water topping-up or level checks, just the appropriate float voltage.

RITAR HT batteries

Ritar HT batteries are 12V high-temperature AGM batteries, from 7 to 200 Ah, built with a specific alloy that tolerates continuous temperatures of 35-50 °C without a drastic reduction in service life. Heat is the great enemy of any lead-acid battery, and this series is designed precisely to fight it.

They are the go-to telecom battery for hot climates: telecom huts and shelters in southern Europe and Africa, unconditioned plant rooms and UPS systems in hot environments. Sealed maintenance-free VRLA technology, ready for float service where other AGM batteries age prematurely.

High-temperature AGM batteries: reliable backup in hot climates

In a conventional lead-acid battery, continuous operation above 25 °C accelerates grid corrosion and shortens its life. The Ritar HT (High Temperature) series uses a specific alloy that tolerates continuous temperatures of 35 to 50 °C without that drastic degradation, keeping the backup available where a standard AGM would need replacing much sooner.

That makes it the natural choice for unconditioned telecom huts in southern Europe and Africa, outdoor cabinets, industrial buildings and any UPS in a hot environment. As a sealed VRLA AGM battery, it needs no maintenance or water topping-up.

Models in the Ritar HT series

HT12-7 — 12V 7 Ah, for compact UPS units, alarms and electronics in warm environments.
HT12-100 — 12V 100 Ah, the usual block in 48V telecom strings.
HT12-200 — 12V 200 Ah, for long runtimes at base stations and critical sites.

How to choose your high-temperature battery

Size by capacity (Ah), string voltage and the real ambient temperature of the installation. Our battery comparison tool lets you compare capacity, size and price across the whole HT range.
