## Quick description

**Odyssey ODP-AGM24M 63Ah 725A** is a marine battery with reinforced anti-vibration case for moorings and offshore use. Tolerates the typical daily cycles on a boat (engine start + night-time services such as lights, sonar, fridge) and holds voltage even when the hull is rolling in open sea.

## 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

## Description

## Marine battery Odyssey ODP-AGM24M ODP 63Ah 725A

63*Ah* Capacity
725*A* Cold cranking
23.30*kg* Weight

The **Odyssey ODP-AGM24M** with AGM technology is a marine battery with **63 Ah** and **725 A** of cold cranking current (EN) for motor and sailing boats, both for engine starting and onboard services. It replaces the original battery without adaptation in boats with a 277 × 173 × 224 mm format: same 63 Ah capacity and the positive terminal on the left.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Reinforced case against vibration and swell.
- Powers onboard services: lights, sounder, GPS, fridge.
- Tolerates the daily cycling of a boat in season.

### What the Odyssey ODP-AGM24M is for

On board, the Odyssey ODP-AGM24M provides 63 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 23.30 kg and M terminals.

### Dimensions, polarity and mounting

In terms of format, the Odyssey ODP-AGM24M measures 277 × 173 × 224 mm (length × width × height) and weighs 23.30 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.

### The Odyssey ODP-AGM24M: ODP range and AGM technology

Within the Odyssey catalogue, the **ODP** series groups the references designed for this use. The ODP-AGM24M is the 63 Ah model of that family, with the same performance as its siblings in other sizes.
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.

### What Odyssey does differently

Odyssey, part of the EnerSys group, makes thin-plate pure-lead (TPPL) batteries: extreme cranking, total vibration resistance and very long service life in motorsport, 4x4, marine and demanding vehicles. All the Odyssey batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Warranty and coverage

The Odyssey ODP-AGM24M comes with the **manufacturer's official warranty** against manufacturing defects. Deep discharge from winter lay-up without charging is not covered.

### How to make it last longer

Protect the terminals with dielectric grease and check the fixing: vibration and swell loosen connections. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

### When you get it and how to return it

Order **before 6:00 pm** 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 **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### Is the ODP-AGM24M model AGM? What does this technology offer?

Yes. The ODP-AGM24M 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 do I fit the ODP-AGM24M model in my boat?

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 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 (−) 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 — with positive on the left 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 many years does this battery last?

Expected lifespan of the Odyssey ODP-AGM24M 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 size is this battery?

Dimensions (length × width × height) are 277×173×224 mm — also written as 277x173x224 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.

### What polarity does the Odyssey ODP-AGM24M battery have?

Polarity: positive on the left. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.

### Will the Odyssey ODP-AGM24M 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-AGM24M typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which interchangeable batteries are there for this one?

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.
