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 135 Ah C20 📏 Dimensions 329×179×278 mm ⚙️ Technology AGM ⚖️ Weight 38 kg 🏷️ Model TROJAN SOLAR AGM - 1700 CYCLES 50% DOD ## Description ## Solar battery Trojan SAGM 12 135 Solar AGM - 1700 Ciclos 50% DOD 135Ah 12V 12*V* Voltage 135*Ah* Capacity 38*kg* Weight The **12 V**, **135 Ah** **Trojan SAGM 12 135** solar battery from the **Solar AGM - 1700 Ciclos 50% DOD** range with AGM technology is designed for off-grid photovoltaic installations and storage systems. It measures 329 × 179 × 278 mm, the format sought by anyone replacing a 135 Ah battery in off-grid PV systems. - Optimised for daily charge and discharge cycles. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Long life on float and moderate cycling. - Good tolerance to extreme temperatures. ### What the Trojan SAGM 12 135 is for Designed for off-grid photovoltaic installations and storage systems, the Trojan SAGM 12 135 tolerates extreme temperatures and long periods of low activity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 38 kg. ### The Trojan SAGM 12 135: Solar AGM - 1700 Ciclos 50% DOD range and AGM technology The SAGM 12 135 is part of the Trojan **Solar AGM - 1700 Ciclos 50% DOD** 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 means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Size, terminals and hold-down of the Trojan SAGM 12 135 The Trojan SAGM 12 135 is made in the 329 × 179 × 278 mm format and weighs 38 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a 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. ### 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. ### Warranty and coverage The Trojan SAGM 12 135 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 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 this battery AGM? What is it for? Yes. The SAGM 12 135 from Trojan uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### What are the dimensions of the Trojan SAGM 12 135 battery? Dimensions (length × width × height) are 329×179×278 mm — also written as 329x179x278 mm — following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ## Compatible vehicles This battery fits 3 vehicles.
