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 160 Ah C20 📏 Dimensions 262×179×273 mm ⚙️ Technology AGM ⚖️ Weight 32 kg 🏷️ Model TROJAN AGM RELIANT ## Description ## Solar battery Trojan T875-AGM AGM Reliant 160Ah 8V 8*V* Voltage 160*Ah* Capacity 32*kg* Weight For off-grid photovoltaic installations and storage systems, the **Trojan T875-AGM** from the **AGM Reliant** range stores **160 Ah** with AGM technology through daily charge and discharge cycles. Its 262 × 179 × 273 mm make it the exact replacement for the 160 Ah battery fitted as standard to many off-grid PV systems. - Compatible with common MPPT and PWM controllers. - Maintenance-free in off-grid installations. - Low self-discharge during the darker months. - AGM: faster recharging and better cycle resistance than a conventional battery. ### Will it fit your current battery tray? In terms of format, the Trojan T875-AGM measures 262 × 179 × 273 mm (length × width × height) and weighs 32 kg. It uses 5 8 15 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. ### What the Trojan T875-AGM is for With 160 Ah, the Trojan T875-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 32 kg and 5 8 15 terminals. ### The Trojan T875-AGM: AGM Reliant range and AGM technology Within the Trojan catalogue, the **AGM Reliant** series groups the references designed for this use. The T875-AGM is the 160 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Why choose Trojan batteries Founded in 1925 in California, Trojan invented the golf cart battery and remains the standard in deep-discharge applications that demand thousands of cycles. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Manufacturer's warranty The Trojan T875-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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. ### Shipping, delivery and returns Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 Trojan T875-AGM an AGM battery and what are the benefits of AGM? Yes. The T875-AGM 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. ### How do I change this battery step by step? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the T875-AGM model? Expected lifespan of the Trojan T875-AGM is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the dimensions of the Trojan T875-AGM battery? Dimensions (length × width × height) are 262×179×273 mm — also written as 262x179x273 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. ### Which interchangeable batteries are there for this one? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## 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 · 2026-10-21*
