# RITAR FT batteries > Ritar FT front-terminal AGM batteries, 12V 50-200 Ah, for UPS and telecom power. Sealed VRLA, maintenance-free, rack-ready. 24h delivery, easy returns. **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [Ritar batteries](https://baterias.com/gb/batteries-ritar) - **Canonical URL**: https://baterias.com/gb/batteries-ritar-ft - **Language**: en-GB ## Description **Ritar FT batteries** are 12V **front-terminal AGM batteries** from 50 to 200 Ah, built for UPS systems and telecom power plants. With the terminals on the front face, each block can be wired and checked without sliding it out of the cabinet, making them ideal for 19" and 23" racks. They are the classic **stationary battery for telecommunications**: base stations, exchanges, 48V battery strings and backup power in critical installations. Sealed **maintenance-free VRLA** technology, designed for years of float service. ## Front-terminal AGM batteries for telecom and UPS The **Ritar FT** series uses a slim, deep case format with the **terminals on the front face**: wiring, torque checks and voltage readings are all done from the visible side, without pulling the battery out of the frame. It is the standard format in **telecom cabinets** and plant rooms where space and access are tight. Like any **sealed VRLA AGM battery**, it needs no water topping-up, releases minimal gas and has very low self-discharge, so it can be installed indoors next to electronic equipment. ### Models in the Ritar FT series - **FT12-50** — 12V 50 Ah, for compact UPS and telecom gear. - **FT12-100** — 12V 100 Ah, the most common block in 48V strings. - **FT12-150** — 12V 150 Ah, for longer autonomy at base stations. - **FT12-200** — 12V 200 Ah, long-runtime backup for critical sites. ### How to choose your front-terminal battery Check the capacity (Ah), the dimensions of the bay and the total string voltage (12, 24 or 48V). With our battery comparison tool you can line up capacity, size and price across the whole FT range. ## Frequently asked questions about Ritar FT batteries ### **What is the advantage of a front-terminal battery over a standard AGM?** The terminals sit on the front face instead of the top lid, so connection and maintenance are done without removing the battery from the rack. They also make better use of 19" and 23" cabinets. ### **Are Ritar FT batteries suitable for a UPS?** Yes. They are stationary batteries designed for float service, both in single-phase UPS units and in 48V telecom backup systems. ### **Do they need maintenance?** No. They are valve-regulated sealed VRLA batteries: there is no water to top up, you only need to keep the float voltage recommended by the manufacturer. ### **Can they be mounted horizontally?** Yes. AGM technology with absorbed electrolyte allows horizontal mounting, which is the usual orientation in telecom racks.
