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 8 V ⚡ Capacity 165 Ah C20 📏 Dimensions 262×179×273 mm ⚙️ Technology AGM ⚖️ Weight 32 kg 🏷️ Model TROJAN SOLAR AGM - 1700 CYCLES 50% DOD ## Description ## Solar battery Trojan SAGM 08 165 Solar AGM - 1700 Ciclos 50% DOD 165Ah 8V 8*V* Voltage 165*Ah* Capacity 32*kg* Weight The **Trojan SAGM 08 165** with AGM technology stores **165 Ah** at **8 V** for off-grid photovoltaic installations and storage systems. Its 262 × 179 × 273 mm make it the exact replacement for the 165 Ah battery fitted as standard to many off-grid PV systems. - Low self-discharge during the darker months. - AGM: faster recharging and better cycle resistance than a conventional battery. - Compatible with common MPPT and PWM controllers. - Maintenance-free in off-grid installations. ### What the Trojan SAGM 08 165 is for Designed for off-grid photovoltaic installations and storage systems, the Trojan SAGM 08 165 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 32 kg. ### Will it fit your current battery tray? In terms of format, the Trojan SAGM 08 165 measures 262 × 179 × 273 mm (length × width × height) and weighs 32 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### The Trojan SAGM 08 165: 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 08 165 is the 165 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Care and maintenance 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. ### Warranty and coverage The Trojan SAGM 08 165 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. ### 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 Trojan SAGM 08 165 an AGM battery and what are the benefits of AGM? Yes. The Trojan SAGM 08 165 is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What size is this battery? Length × width × height: 262x179x273 mm. Height is measured to the top of the terminals. Measure your device's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. ### Trojan SAGM 08 165 or Trojan T875-AGM: which one to choose? Same case and same technology as the SAGM 08 165: an alternative by size, not an official equivalent. Compared with the SAGM 08 165 it has 5 Ah less. It costs 0,90 € 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. ## 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*
