It measures 52 × 52 × 12 mm, the format sought by anyone replacing a 12 Ah battery in UPS, alarm and emergency systems. - Maintenance-free for its whole service life. - Sealed and gas-free: suitable for cabinets and offices. - Long float life under permanent charge. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### Will it fit your current battery tray? In terms of format, the Cyclon 2V-J measures 52 × 52 × 12 mm (length × width × height) and weighs 0.84 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Cyclon 2V-J is for The Cyclon 2V-J is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 0.84 kg. ### The Cyclon 2V-J: Battery 2V Single Cell range and AGM technology The **Battery 2V Single Cell** is the Cyclon range the 2V-J belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery. ### Why choose Cyclon batteries Cyclon cells and monoblocs are the reference when the application demands power, vibration resistance and reliability in extreme conditions. All the Cyclon batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Official warranty The Cyclon 2V-J 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. ### How to make it last longer Replace all the batteries in the set at once and avoid environments continuously above 25 °C. 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 the Cyclon 2V-J an AGM battery and what are the benefits of AGM? Yes. The 2V-J from Cyclon 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 Cyclon 2V-J 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. ### What is the service life of the 2V-J model? Expected lifespan of the Cyclon 2V-J 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 dimensions of the Cyclon 2V-J battery? Dimensions (length × width × height) are 52×52×123 mm — also written as 52x52x123 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 Cyclon 2V-J? 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 — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-28*
