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 6 V ⚡ Capacity 377 Ah C20 📏 Dimensions 296×176×446 mm ⚙️ Technology Lead-acid ⚖️ Weight 54 kg 🏷️ Model TROJAN SOLAR PREMIUM - SMART CARBON ## Description ## Solar battery Trojan SPRE 06 415 Solar Premium - Smart Carbon 377Ah 6V 6*V* Voltage 377*Ah* Capacity 54*kg* Weight The **6 V**, **377 Ah** **Trojan SPRE 06 415** solar battery from the **Solar Premium - Smart Carbon** range with conventional lead-acid technology is designed for off-grid photovoltaic installations and storage systems. Its 296 × 176 × 446 mm make it the exact replacement for the 377 Ah battery fitted as standard to many off-grid PV systems. - Low self-discharge during the darker months. - Good balance of capacity, cranking power and price. - Compatible with common MPPT and PWM controllers. - Maintenance-free in off-grid installations. ### What the Trojan SPRE 06 415 is for Designed for off-grid photovoltaic installations and storage systems, the Trojan SPRE 06 415 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 54 kg. ### The Trojan SPRE 06 415: Solar Premium - Smart Carbon range and conventional lead-acid technology The SPRE 06 415 is part of the Trojan **Solar Premium - Smart Carbon** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use. ### Size, terminals and hold-down of the Trojan SPRE 06 415 In terms of format, the Trojan SPRE 06 415 measures 296 × 176 × 446 mm (length × width × height) and weighs 54 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. ### How to make it last longer In the darker months, check the voltage periodically and avoid full discharges. Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. ### Warranty and coverage The Trojan SPRE 06 415 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 Orders placed **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 ### How do I fit the SPRE 06 415 model in my device? 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. ### How long does the Trojan SPRE 06 415 battery last? Expected lifespan of the Trojan SPRE 06 415 is 4 to 6 years in regular device use without 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 measurements of the SPRE 06 415 model? Dimensions (length × width × height) are 296×176×446 mm — also written as 296x176x446 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 batteries are equivalent to the Trojan SPRE 06 415? 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 · 2026-10-22*
