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 12 V ⚡ Capacity 105 Ah C20 📏 Dimensions 325×173×237 mm ⚙️ Technology AGM ⚖️ Weight 30 kg 🏷️ Model TROJAN SOLAR AGM - 1700 CYCLES 50% DOD ## Description ## Solar battery Trojan SAGM 12 105 Solar AGM - 1700 Ciclos 50% DOD 105Ah 12V 12*V* Voltage 105*Ah* Capacity 30*kg* Weight The **Trojan SAGM 12 105** with AGM technology stores **105 Ah** at **12 V** for off-grid photovoltaic installations and storage systems. It measures 325 × 173 × 237 mm, the format sought by anyone replacing a 105 Ah battery in off-grid PV systems. - Long life on float and moderate cycling. - Good tolerance to extreme temperatures. - Optimised for daily charge and discharge cycles. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### What the Trojan SAGM 12 105 is for With 105 Ah, the Trojan SAGM 12 105 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 30 kg. ### The Trojan SAGM 12 105: Solar AGM - 1700 Ciclos 50% DOD range and AGM technology Within the Trojan catalogue, the **Solar AGM - 1700 Ciclos 50% DOD** series groups the references designed for this use. The SAGM 12 105 is the 105 Ah model of that family, with the same performance as its siblings in other sizes. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Dimensions, polarity and mounting In terms of format, the Trojan SAGM 12 105 measures 325 × 173 × 237 mm (length × width × height) and weighs 30 kg. 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. ### Trojan: the maker behind the SAGM 12 105 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Care and maintenance Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. In the darker months, check the voltage periodically and avoid full discharges. ### Official warranty The Trojan SAGM 12 105 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. ### Delivery times and returns Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is the SAGM 12 105 model AGM? What does this technology offer? Yes: the SAGM 12 105 from Trojan uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It withstands more cycles than a conventional battery and copes better with heat. ### What are the dimensions of the Trojan SAGM 12 105 battery? Its dimensions are 325×173×237 mm, also written 325x173x237 mm; the height already includes the terminals. Check the room available in your device, because a single millimetre too much can stop the clamp from closing. ### Trojan SAGM 12 105 or Trojan 31-AGM SV: which one to choose? It has the same dimensions, voltage and technology as the SAGM 12 105, although it is not a manufacturer-approved equivalent. Compared with the SAGM 12 105 it has 5 Ah less. It costs 53,80 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
