Ideal when the battery discharges and recharges daily rather than just cranking the engine (mobility scooters, backup systems, golf, pallet trucks). ## Why this deep-cycle battery? - **Daily cycling without wear** handles deep discharges without losing capacity - **Sealed AGM/GEL** no maintenance, no risk of spills - **Thousands of useful cycles** over its full lifetime πŸ”Œ Voltage 12 V ⚑ Capacity 134 Ah C20 πŸ“ Dimensions 329Γ—179Γ—278 mm βš™οΈ Technology AGM βš–οΈ Weight 39 kg 🏷️ Model Trojan Solar Aes ## Description ## Deep-cycle battery Trojan SAES 12 135 Solar AES 134Ah 12V 12*V* Voltage 134*Ah* Capacity 39*kg* Weight For equipment that is discharged and recharged every day, the **Trojan SAES 12 135** from the **Solar AES** range offers **134 Ah** with AGM technology and thousands of useful cycles. It replaces the original battery without adaptation in deep-discharge equipment with a 329 Γ— 179 Γ— 278 mm format: same 134 Ah capacity. - Sealed and maintenance-free. - Reinforced construction for continuous use. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Repeated deep discharges without capacity loss. ### What the Trojan SAES 12 135 is for With 134 Ah, the Trojan SAES 12 135 offers thousands of useful cycles in equipment that is discharged and recharged every day. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 39 kg. ### Size, terminals and hold-down of the Trojan SAES 12 135 In terms of format, the Trojan SAES 12 135 measures 329 Γ— 179 Γ— 278 mm (length Γ— width Γ— height) and weighs 39 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Trojan SAES 12 135: Solar AES range and AGM technology Within the Trojan catalogue, the **Solar AES** series groups the references designed for this use. The SAES 12 135 is the 134 Ah model of that family, with the same performance as its siblings in other sizes. AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly. ### Trojan: the maker behind the SAES 12 135 Founded in 1925 in California, Trojan invented the golf cart battery and remains the standard in deep-discharge applications that demand thousands of cycles. All the Trojan batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Trojan SAES 12 135 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Avoid repeated full discharges and recharge fully after each use. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 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 **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the Trojan SAES 12 135 an AGM battery and what are the benefits of AGM? Yes. The SAES 12 135 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 do I change this battery step by step? 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 (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. ### What is the service life of the SAES 12 135 model? Expected lifespan of the Trojan SAES 12 135 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 equivalents of the SAES 12 135 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 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. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” automotive battery specialists since 2012. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-26*
