Tolerates extreme temperatures well, with low self-discharge during winter shutdowns or between stays at vacation homes. ## Why this solar battery? - **Designed for solar systems** optimised for daily charge/discharge cycles - **Handles extreme temperatures** in technical rooms or outdoor installs - **Minimal self-discharge** when left idle over winter or holidays 🔌 Voltage 6 V ⚡ Capacity 217 Ah C20 📏 Dimensions 262×179×273 mm ⚙️ Technology AGM ⚖️ Weight 31 kg 🏷️ Model TROJAN AGM RELIANT ## Description ## Solar battery Trojan T105-AGM AGM Reliant 217Ah 6V 6*V* Voltage 217*Ah* Capacity 31*kg* Weight The **Trojan T105-AGM** with AGM technology stores **217 Ah** at **6 V** for off-grid photovoltaic installations and storage systems. Measuring 262 × 179 × 273 mm, it is the direct replacement for off-grid PV systems fitted from the factory with a 217 Ah battery of this format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Low self-discharge during the darker months. - Maintenance-free in off-grid installations. - Compatible with common MPPT and PWM controllers. ### Will it fit your current battery tray? In terms of format, the Trojan T105-AGM measures 262 × 179 × 273 mm (length × width × height) and weighs 31 kg. It uses 5 8 15 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### What the Trojan T105-AGM is for With 217 Ah, the Trojan T105-AGM stores the energy from your panels for the night and cloudy days. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31 kg and 5 8 15 terminals. ### The Trojan T105-AGM: AGM Reliant range and AGM technology The T105-AGM is part of the Trojan **AGM Reliant** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery. ### What Trojan does differently Trojan Battery is the world reference in deep-cycle batteries: golf carts, cleaning machines, aerial platforms and solar systems rely on its T2 technology and longevity. We guarantee that every Trojan arrives new, charged and with the manufacturer's full warranty. ### Manufacturer's warranty The Trojan T105-AGM comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you. ### Usage and maintenance tips Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### When you get it and how to return it Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the T105-AGM model AGM? What does this technology offer? Yes, it is AGM. In an AGM battery such as the T105-AGM, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What size is this battery? It measures 262×179×273 mm in length × width × height, with the terminals included in the height. Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. ### Trojan T105-AGM or Trojan SAGM 06 220: which one to choose? Same case and same technology as the T105-AGM: an alternative by size, not an official equivalent. Compared with the T105-AGM it has 3 Ah more. It costs 51,90 € more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ### Trojan T105-AGM or Trojan 6V-AGM: which one to choose? Same case and same technology as the T105-AGM: an alternative by size, not an official equivalent. Compared with the T105-AGM it has 17 Ah less. It costs 60,20 € more. If the polarity matches and your equipment had a similar capacity, it works as a replacement; if in doubt, ask us with your model. ## Compatible vehicles This battery fits 37 vehicles.
