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 443 Ah C20 📏 Dimensions 296×176×446 mm ⚙️ Technology Lead-acid ⚖️ Weight 57 kg 🏷️ Model TROJAN SOLAR SIGNATURE 100 CYCLES 50% DOD ## Description ## Solar battery Trojan SSIG 06 490 Solar Signatura 100 Ciclos 50% DOD 443Ah 6V 6*V* Voltage 443*Ah* Capacity 57*kg* Weight The **Trojan SSIG 06 490** with conventional lead-acid technology stores **443 Ah** at **6 V** for off-grid photovoltaic installations and storage systems. It replaces the original battery without adaptation in off-grid PV systems with a 296 × 176 × 446 mm format: same 443 Ah capacity. - Good tolerance to extreme temperatures. - Long life on float and moderate cycling. - Conventional lead-acid: the most proven and economical technology. - Optimised for daily charge and discharge cycles. ### What the Trojan SSIG 06 490 is for The Trojan SSIG 06 490 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 57 kg. ### The Trojan SSIG 06 490: Solar Signatura 100 Ciclos 50% DOD range and conventional lead-acid technology The SSIG 06 490 is part of the Trojan **Solar Signatura 100 Ciclos 50% DOD** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Will it fit your current battery tray? In terms of format, the Trojan SSIG 06 490 measures 296 × 176 × 446 mm (length × width × height) and weighs 57 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### 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. ### Official warranty The Trojan SSIG 06 490 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 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 and Canary 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 is the Trojan SSIG 06 490 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 SSIG 06 490 battery last? Expected lifespan of the Trojan SSIG 06 490 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 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. ### What are the equivalents of the SSIG 06 490 model? 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. ## Reviews - **Average rating**: 4.72 / 5 (9 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-28*
