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 πŸ”Œ Voltage 12 V ⚑ Capacity 50 Ah C20 πŸ“ Dimensions 228Γ—139Γ—204 mm βš™οΈ Technology AGM βš–οΈ Weight 18 kg 🏷️ Model TROJAN AGM ## Description ## Solar battery Trojan 22-AGM 50Ah 12V 12*V* Voltage 50*Ah* Capacity 18*kg* Weight For off-grid photovoltaic installations and storage systems, the **Trojan 22-AGM** stores **50 Ah** with AGM technology through daily charge and discharge cycles. Its 228 Γ— 139 Γ— 204 mm make it the exact replacement for the 50 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. ### What the Trojan 22-AGM is for The Trojan 22-AGM 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 18 kg and 15 terminals. ### Size, terminals and hold-down of the Trojan 22-AGM It has external dimensions of 228 Γ— 139 Γ— 204 mm and weighs 18 kg. It uses 15 terminals, the system that anchors and connects it in the vehicle. 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. ### Technology inside the Trojan 22-AGM Within the Trojan catalogue, the 22-AGM is the 50 Ah model designed for this application. 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. ### Trojan: the maker behind the 22-AGM 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. ### Manufacturer's warranty The Trojan 22-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. ### 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. ### Delivery times 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 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 ### Is this battery AGM? What is it for? Yes. The 22-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 is the Trojan 22-AGM 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 (βˆ’) 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 β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). 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 22-AGM battery last? Expected lifespan of the Trojan 22-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 measurements of the 22-AGM model? Dimensions (length Γ— width Γ— height) are 228Γ—139Γ—204 mm β€” also written as 228x139x204 mm β€” 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 22-AGM? 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 β€” 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 (42 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-01*
