This high density paste optimizes the development of porosity in the active material using active material more effectively, resulting in sustained battery performance for a longer period of time. T2 T2 technology introduces a T2 metallic agent in the Alpha Plus paste, further strengthening its electrochemical processing capabilities. Together, Alpha Plus pasta with T2 technology increases both sustained capacity and total general amps -ora, resulting in more operational power for its application.It is a key reason why trojan batteries consistently exceed competition. ### Ideal for: - Renewable energy - Solar ### Battery advantages TROJAN J305P-AC 330Ah 6V - Better performance in batteries operating in EDCP - Greater shelf life - Free of mantenimient ### Battery characteristics TROJAN J305P-AC 330Ah 6V - None - None - None - None - None - None ### How to find the right battery for your vehicle or device?

Three ways: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team for the J305P-AC; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 9:00–18:00 CET). ### How is the Trojan J305P-AC 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 many years of warranty does the J305P-AC model cover? The official manufacturer warranty is 1 year and covers manufacturing defects. Coverage includes cell breakdowns, internal short-circuits and abnormal capacity decreases. Wear from misuse (prolonged overcharging, wrong charger or faulty alternator) is not covered. If the battery fails, we replace it at no cost after a technical inspection. ### How long does Trojan J305P-AC delivery take? In mainland Spain and Portugal it arrives in 24 h if you order before 17:00 and the battery is in stock — it leaves the same day and arrives the next business day. Afternoon or weekend orders ship the next business day. For Balearics, Canaries and other EU destinations, allow 2-5 days. Shipping cost is calculated in the cart based on destination and service (standard, express, cash on delivery). Tracking number is sent by email + SMS as soon as the parcel ships. ### How do I return the J305P-AC model if it doesn't fit? Yes. You have 14 days from delivery to return it. In mainland Spain and Portugal returns are FREE — we cover the return shipping cost via prepaid label. In other EU countries the return shipping cost is the customer's. It must arrive in its original packaging with no signs of installation. If it was defective, the warranty covers replacement even after the 14-day period. ### How much does the Trojan J305P-AC battery cost? The current price at baterias.com is 617,81 € (VAT included; 510,59 € excl. VAT), updated every 24 hours. The applicable VAT may vary with the destination country and is confirmed in the cart. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). ### Where can I buy this battery with full warranty? At baterias.com — authorised distributor with real stock, 24h delivery in mainland Spain and Portugal if you order before 17:00, and full manufacturer warranty. Shipping cost is calculated in the cart based on destination and chosen service (standard, express, cash on delivery). Secure payment by card, Bizum, PayPal or bank transfer. If you choose at-home installation, our technician will take the used battery and dispose of it through an authorised collection point. ### How many years does this battery last? Expected lifespan of the Trojan J305P-AC 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 J305P-AC model? Dimensions (length × width × height) are 296×176×366 mm — also written as 296x176x366 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. ### How many kilos does this battery weigh? It weighs 44 kg. Most of the weight is lead. If you plan to fit it yourself, use gloves and a carrying strap (AGM batteries are slightly heavier than conventional due to the absorbent glass-mat fibre). ### How many Ah and CCA does this battery have? Nominal capacity 330 Ah[?cca: and [cold-cranking amps A]] at 6 V. Ah measure the total energy available (autonomy); CCA (also written A in cold or EN under the European standard) measure the instantaneous power to crank the starter motor. A battery with more CCA starts better in winter; one with more Ah keeps accessories on for longer. ### Which batteries are equivalent to the Trojan J305P-AC? 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. ### Which is better: Trojan J305P-AC or an alternative from another brand? This battery and its equivalents from Bosch, Tudor or Exide are technically comparable: same dimensions, same voltage and same capacity. The differences are warranty (Varta and Bosch: 2 years; Tudor and Exide: 2 years on the equivalent line), manufacturing plant (Varta and Bosch share origin in the Clarios Group; Tudor and Exide belong to Exide Technologies) and price. For private use any of these brands will give 4-6 years of life. Compare them in the "Equivalents" section. ### What reviews does the J305P-AC model have?
