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 102 Ah C20 📏 Dimensions 341×173×234 mm ⚙️ Technology AGM ⚖️ Weight 31 kg 🏷️ Model TROJAN AGM RELIANT ## Description ## Solar battery Trojan OverDrive AGM 31 AGM Reliant 102Ah 12V 12*V* Voltage 102*Ah* Capacity 31*kg* Weight The **12 V**, **102 Ah** **Trojan OverDrive AGM 31** solar battery from the **AGM Reliant** range with AGM technology is designed for off-grid photovoltaic installations and storage systems. It measures 341 × 173 × 234 mm, the format sought by anyone replacing a 102 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 OverDrive AGM 31 is for The Trojan OverDrive AGM 31 is designed for off-grid photovoltaic installations and storage systems. Size the capacity so as not to discharge more than 50% daily and you will greatly extend its life. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31 kg and 11 terminals. ### Size, terminals and hold-down of the Trojan OverDrive AGM 31 In terms of format, the Trojan OverDrive AGM 31 measures 341 × 173 × 234 mm (length × width × height) and weighs 31 kg. It uses 11 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Trojan OverDrive AGM 31: AGM Reliant range and AGM technology The **AGM Reliant** is the Trojan range the OverDrive AGM 31 belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. 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. ### Trojan: the maker behind the OverDrive AGM 31 Founded in 1925 in California, Trojan invented the golf cart battery and remains the standard in deep-discharge applications that demand thousands of cycles. All the Trojan batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Trojan OverDrive AGM 31 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. ### How to make it last longer Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. In the darker months, check the voltage periodically and avoid full discharges. ### Shipping, delivery and returns Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the OverDrive AGM 31 model AGM? What does this technology offer? Yes: the OverDrive AGM 31 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 size is this battery? It measures 341×173×234 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. ## Compatible vehicles This battery fits 1 vehicles.
