### Size, terminals and hold-down of the Odyssey ODP-AGM48-H6-L3

It has external dimensions of 277 × 175 × 188 mm and weighs 21.80 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 SAE terminals, the system that anchors and connects it in the vehicle. 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.

### What the Odyssey ODP-AGM48-H6-L3 is for

With 69 Ah, the Odyssey ODP-AGM48-H6-L3 is the replacement for cars with Start-Stop, regenerative braking and heavy electrical loads. After the swap it may be necessary to register the new battery in the ECU so that energy management works correctly. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 21.80 kg and SAE terminals.

### The Odyssey ODP-AGM48-H6-L3: ODP range and AGM technology

The **ODP** is the Odyssey range the ODP-AGM48-H6-L3 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.

### What Odyssey does differently

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.

### Manufacturer's warranty

The Odyssey ODP-AGM48-H6-L3 comes with the **manufacturer's official warranty**. To keep it valid, always fit the same technology as the original battery (AGM or EFB) and register the replacement if your vehicle requires it.

### Usage and maintenance tips

Do not mix technologies: a conventional battery in a Start-Stop car degrades within months. 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

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 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 ODP-AGM48-H6-L3 model AGM? What does this technology offer?

Yes. The ODP-AGM48-H6-L3 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 cars with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

### Is the Odyssey ODP-AGM48-H6-L3 battery suitable for Start-Stop?

Yes. As AGM technology it is designed for Start-Stop vehicles. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. EFB is recommended for basic Start-Stop; AGM is recommended when regenerative braking is also present, thanks to its higher cycle capability. It works straight out of the box — on most modern vehicles registering the battery via OBD is recommended so the alternator automatically applies the optimal charging profile.

### How is the Odyssey ODP-AGM48-H6-L3 battery installed in the vehicle?

In most cars 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 cars with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Odyssey ODP-AGM48-H6-L3 battery last?

Expected lifespan of the Odyssey ODP-AGM48-H6-L3 is 5 to 8 years in mild-climate car 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-AGM48-H6-L3 battery?

Dimensions (length × width × height) are 277×175×188 mm — also written as 277x175x188 mm and correspond to the European L3 case size — following the European DIN standard. Always measure the space in your car 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-AGM48-H6-L3 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-AGM48-H6-L3 battery fit my car?

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-AGM48-H6-L3 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### What are the equivalents of the ODP-AGM48-H6-L3 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 cars. See the "Equivalents" section to view recommended options at the same performance level.

### What advantages does the Odyssey ODP-AGM48-H6-L3 AGM battery offer over an EFB?

AGM (Absorbent Glass Mat) technology uses absorbent fibreglass that retains the electrolyte, eliminating leaks and allowing up to 3× more charge/discharge cycles than a conventional battery. It is the recommended option when the car has advanced Start-Stop with regenerative braking (BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO, Volvo i-Stop). Withstands tilted positions, high vibration and extreme temperatures better than EFB. The Odyssey ODP-AGM48-H6-L3 is fully original and meets European EN 50342-6 standards for advanced Start-Stop.

### Is there anything to do after replacing a Start-Stop battery?

On most cars it is not strictly necessary — the alternator detects the new battery and adapts the charge automatically. It is recommended to register the battery via OBD so that the alternator applies the optimal charging profile from the first minute and extends the battery life as much as possible (especially on brands with sophisticated BMS: BMW, Mercedes, Audi, Volvo, Land Rover). Any workshop with an OBD scanner (~10-15 € labour) does it in 5 minutes. DIY apps: VCDS / Carista (VAG), Bimmercode (BMW), iCarsoft. If you do not register, the car will still start correctly — the alternator just takes a few days to adjust the profile. The Odyssey ODP-AGM48-H6-L3 ships factory-charged at 80-90% so you can use it straight after fitting.
