Withstands constant chassis vibration, supports long cold-engine cranks and keeps auxiliary services running (tachograph, heater, refrigeration, GPS) during driver's mandatory rest stops. ### Why this truck battery? - **True Heavy Duty** built for intensive professional use - **Long cold-diesel cranks** reliable even in extreme cold - **Powers services at idle** tachograph, heater and lights with engine off πŸ”Œ Voltage 12 V ⚑ Capacity 165 Ah C20 πŸ”‹ Cold cranking 850 A EN-1 πŸ“ Dimensions 354Γ—241Γ—285 mm βš™οΈ Technology Lead-acid βš–οΈ Weight 45,3 kg 🏷️ Model EXIDE START PRO ## Description ## Truck battery Exide EJ165A1 Start PRO 165Ah 850A 12V 12*V* Voltage 165*Ah* Capacity 850*A* Cold cranking 45.30*kg* Weight The **Exide EJ165A1 truck battery** is rated at **12 V**, **165 Ah** and **850 A** of cold cranking current (EN) from the **Start PRO** range, and is prepared for trucks, buses, tractors and heavy machinery. It replaces the original battery without adaptation in trucks with a 354 Γ— 241 Γ— 285 mm format: same 165 Ah capacity. - Powerful cold cranking for large-displacement diesel engines. - Designed for 24 V installations with two batteries in series. - Conventional lead-acid: the most proven and economical technology. - Heavy Duty construction for intensive professional use. ### What the Exide EJ165A1 is for Designed for trucks, buses, tractors and heavy machinery, the Exide EJ165A1 withstands constant chassis vibration and discharges during stops with active loads. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 45.30 kg. ### The Exide EJ165A1: Start PRO range and conventional lead-acid technology The **Start PRO** is the Exide range the EJ165A1 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. Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour. ### Dimensions, polarity and mounting In terms of format, the Exide EJ165A1 measures 354 Γ— 241 Γ— 285 mm (length Γ— width Γ— height) and weighs 45.30 kg. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters. ### Exide: the maker behind the EJ165A1 With more than a century of history, Exide Technologies manufactures automotive, marine, motorcycle and industrial batteries in Europe. Its presence as original equipment on assembly lines vouches for the quality of every reference. All the Exide batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### How to make it last longer In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery. ### Official warranty The Exide EJ165A1 comes with the **manufacturer's official warranty** against manufacturing defects. An important note for commercial vehicles: most trucks use **two batteries connected in series** (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace **both at the same time**. ### Delivery times and returns Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### How is the Exide EJ165A battery installed in the vehicle? In most trucks 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 trucks 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 EJ165A model? Expected lifespan of the Exide EJ165A is 4 to 6 years in regular truck 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 EJ165A model? Dimensions (length Γ— width Γ— height) are 354Γ—241Γ—285 mm β€” also written as 354x241x285 mm β€” following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Will the Exide EJ165A battery fit my truck? Three options to confirm: 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; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year β€” we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The EJ165A typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the EJ165A 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 trucks. See the "Equivalents" section to view recommended options at the same performance level. ## Equivalent batteries - [TUDOR TJ165A1](https://baterias.com/gb/battery-tudor-tj165a1-165ah-850a) ## Reviews - **Average rating**: 4.77 / 5 (32 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· 2026-09-29*
