Sealed and maintenance-free. ### Why this marine battery? - **Marine design** built for boat swell and vibration - **Dual function** starts the engine and powers onboard services - **Sealed and safe** maintenance-free even when the boat rolls ⚡ Capacity 60 Ah C20 🔋 Cold cranking 710 A SAE 📏 Dimensions 277×173×198 mm ⚙️ Technology AGM 🧭 Polarity Positive on the left ⚖️ Weight 21,2 kg 🏷️ Model ODP ## Description ## Marine battery Odyssey ODP-AGM34M ODP 60Ah 710A 60*Ah* Capacity 710*A* Cold cranking 21.20*kg* Weight With **60 Ah** at ** V** and **710 A** of cold cranking current (EN), the **Odyssey ODP-AGM34M** from the **ODP** range is built for motor and sailing boats, both for engine starting and onboard services. Its 277 × 173 × 198 mm and the positive terminal on the left make it the exact replacement for the 60 Ah battery fitted as standard to many boats. - Ready for starting outboard and inboard engines. - AGM: faster recharging and better cycle resistance than a conventional battery. - Resistant to humidity and salt air. - Sealed: no spills or gases in the locker. ### What the Odyssey ODP-AGM34M is for On board, the Odyssey ODP-AGM34M provides 60 Ah with a case reinforced against vibration and swell. Keep the terminals clean and protected from salt humidity. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 21.20 kg and M terminals. ### The Odyssey ODP-AGM34M: ODP range and AGM technology The **ODP** is the Odyssey range the ODP-AGM34M 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. 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. ### Size, terminals and hold-down of the Odyssey ODP-AGM34M The Odyssey ODP-AGM34M is made in the 277 × 173 × 198 mm format and weighs 21.20 kg. The positive terminal on the left decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses M terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Odyssey: the maker behind the ODP-AGM34M Odyssey batteries combine starting and deep cycling in a single sealed pure-lead unit, with some of the longest warranties on the market. We guarantee that every Odyssey arrives new, charged and with the manufacturer's full warranty. ### How to make it last longer At the end of the season, charge the battery fully and, if possible, keep it on a charger over the winter lay-up. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Warranty and coverage The Odyssey ODP-AGM34M comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered. ### 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 Odyssey ODP-AGM34M an AGM battery and what are the benefits of AGM? Yes. The ODP-AGM34M from Odyssey 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 boats with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How is the Odyssey ODP-AGM34M battery installed in the vehicle? In most boats 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 boats with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Odyssey ODP-AGM34M battery last? Expected lifespan of the Odyssey ODP-AGM34M is 5 to 8 years in mild-climate boat 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 Odyssey ODP-AGM34M battery? Dimensions (length × width × height) are 277×173×198 mm — also written as 277x173x198 mm — following the European DIN standard. Always measure the space in your boat before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Will the Odyssey ODP-AGM34M battery fit my boat? 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 — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The ODP-AGM34M typically fits a wide range of European vehicles thanks to its standard DIN case format. ### What are the equivalents of the ODP-AGM34M 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 — an EFB cannot be replaced with a conventional battery in Start-Stop boats. 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 · 2026-09-30*
