# Stationary VRLA batteries: AGM and GEL > Over 340 stationary VRLA batteries for UPS, telecoms, alarms and renewable energy from Long, Ritar, Fulbat and Q-Battery, with the final price incl. VAT. **Category:** [Beginning](https://bateriasonline.es/en/) → [Battery types: starter, deep cycle, traction and stationary](https://bateriasonline.es/en/batteries) - **Canonical URL**: https://bateriasonline.es/en/stationary-batteries - **Language**: en ## Description Sealed, maintenance-free batteries for back-up and continuous power equipment; choose by voltage, capacity and terminal type. A stationary battery stays in one place, sits on charge and supplies power the moment the mains drops or the system calls for it. This section groups **VRLA AGM and GEL** blocks in 2, 6 and 12 V built for fixed duty, either on float or in light cycling. Narrow the list by voltage, Ah rating, dimensions and terminal style to find the exact replacement for your equipment. ## What makes a battery stationary Most of its life is spent on **float charge**: the charger holds it full at a steady voltage (roughly 2.25–2.30 V per cell at 20 °C, depending on the maker) and it only discharges during an outage or a short peak. It is therefore designed to last years in standby, with low self-discharge and no electrolyte maintenance. VRLA blocks are sealed and recombine nearly all internal gas, so they can go into cabinets and equipment rooms. ## AGM or GEL for your application - **AGM**: low internal resistance and strong high-current delivery, which is why most uninterruptible power supplies use it. - **GEL**: copes better with repeated deep discharges and moderate heat, making it a good fit for daily cycling. The **design life** printed on datasheets (5, 10 or 12 years on float) is measured in the lab at 20 °C. Heat is what shortens it in the real world: every 10 °C above that reference can roughly halve it. ## Picking the right replacement Read four values off the battery you are removing: nominal voltage, Ah capacity (a 20-hour rating and a 10-hour rating are not directly comparable), outside dimensions and **terminal type** (F1/F2 faston, M5/M6 bolt, front terminal…). Where several blocks are wired in series, replace the whole string at once with units from the same batch; mixing old and new ones unbalances charging.

That is not what it is built for. It supplies current over minutes or hours, not a burst of hundreds of amps for a few seconds. A vehicle needs a starter battery. ### How long can it sit on a shelf uncharged? VRLA blocks self-discharge slowly, yet stored units should be recharged every few months, sooner in a warm storeroom. A battery left flat for long sulphates and loses capacity. ### Does mounting orientation matter? Many AGM models accept side mounting, though not all do. Check the datasheet of the specific model before laying it on its side. ## Choose by brand The same stationary VRLA batteries: AGM and GEL, filtered by manufacturer.
