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 229 Ah C20 📏 Dimensions 262×181×298 mm ⚙️ Technology Lead-acid ⚖️ Weight 30 kg 🏷️ Model TROJAN SOLAR PREMIUM - SMART CARBON ## Description ## Solar battery Trojan SPRE 06 255 Solar Premium - Smart Carbon 229Ah 6V 6*V* Voltage 229*Ah* Capacity 30*kg* Weight The **6 V**, **229 Ah** **Trojan SPRE 06 255** solar battery from the **Solar Premium - Smart Carbon** range with conventional lead-acid technology is designed for off-grid photovoltaic installations and storage systems. It measures 262 × 181 × 298 mm, the format sought by anyone replacing a 229 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. - Conventional lead-acid: the most proven and economical technology. ### What the Trojan SPRE 06 255 is for Designed for off-grid photovoltaic installations and storage systems, the Trojan SPRE 06 255 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 30 kg. ### Will it fit your current battery tray? The Trojan SPRE 06 255 is made in the 262 × 181 × 298 mm format and weighs 30 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. ### The Trojan SPRE 06 255: Solar Premium - Smart Carbon range and conventional lead-acid technology Within the Trojan catalogue, the **Solar Premium - Smart Carbon** series groups the references designed for this use. The SPRE 06 255 is the 229 Ah model of that family, with the same performance as its siblings in other sizes. The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop. ### Usage and maintenance tips Size the installation so as not to discharge the battery more than 50% daily and set the controller to the battery technology. On batteries with filler caps, check the electrolyte level and top up only with distilled water. ### Warranty and coverage The Trojan SPRE 06 255 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. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How is the Trojan SPRE 06 255 battery installed in the vehicle? 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 this page. 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 06 255 battery last? Expected lifespan of the Trojan SPRE 06 255 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 size is this battery? Dimensions (length × width × height) are 262×181×298 mm — also written as 262x181x298 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 06 255? 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 2015. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-10-10*
