Odyssey ODP-AGM24 · Car battery 63Ah 725A AGM

Yes: the ODP-AGM24 from Odyssey uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. It tolerates heat better and handles more cycles than a conventional battery, which is why it is the required technology with advanced Start-Stop and regenerative braking.

Yes. It is a AGM battery of 63 Ah, designed for vehicles with Start-Stop. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. If the car recovers energy when braking, AGM is recommended for its higher cycle count; for basic Start-Stop, EFB. The manufacturer's specification comes first. Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start.

With a 10 mm spanner, swapping in the Odyssey ODP-AGM24 takes 15 to 30 minutes on most cars; if the battery sits in the boot or under a seat, allow up to twice as long. With the engine stopped and the key removed, always start with the negative (−) terminal, then the positive (+). Free the clamp, swap the battery without turning it round (this one has positive on the left) so the polarity stays the same, and reconnect in reverse: positive (+) first, negative (−) last. If the car has Start-Stop or BMS: a) the technology must match the original (AGM or EFB) or be higher, because a conventional battery would fail within months; b) undo the negative cable at its nut, leaving the IBS sensor in place; c) it is advisable to register the battery via OBD so the alternator applies the proper charging profile. Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog.

Estimated lifespan of the Odyssey ODP-AGM24: 5 to 8 years in mild-climate car use with Start-Stop. Treat it as an approximate guide, as every case is different. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop.

Length × width × height: 277x173x224 mm. Height is measured to the top of the terminals. Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close.

The ODP-AGM24 has the positive on the left: that is its polarity. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.

For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the car handbook disagree, go with what the manufacturer says.

To replace the Odyssey ODP-AGM24 without modifications, the other battery must be identical in size, polarity, Ah and CCA. Technology matters too: in Start-Stop cars, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page.

It is the recommended choice for advanced Start-Stop with regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop) and copes better than an EFB with tilting, vibration and extreme temperatures. Many more charge/discharge cycles than a conventional battery and no leaks: that is what AGM technology brings, with the electrolyte absorbed in glass fibre. This ODP-AGM24 delivers 725 A cold cranking (EN).

Advisable, yes; essential, on most cars, no. Registering it via OBD makes the alternator charge with the optimum profile from the first minute and extends battery life, which matters most on brands with sophisticated BMS such as BMW, Mercedes, Audi, Volvo or Land Rover. Without registration there is no starting problem: the alternator adjusts the profile within a few days. A workshop only needs an OBD scanner and a few minutes.
