## Description

## Start-Stop battery Odyssey ODP-AGM34 ODP 61Ah 792A

61*Ah* Capacity
792*A* Cold cranking
21.10*kg* Weight

The **Odyssey ODP-AGM34** with AGM technology delivers the **61 Ah** at **V** and **792 A** of cold cranking current (EN) that cars with Start-Stop, regenerative braking and heavy electrical loads need. It measures 274 × 173 × 201 mm and the positive terminal on the left, the format sought by anyone replacing a 61 Ah battery in Start-Stop cars.
- Withstands hundreds of starts a day without degrading.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Up to three times the cycles of a conventional battery.
- Compatible with regenerative braking and energy management (BMS).

### What the Odyssey ODP-AGM34 is for

With 61 Ah, the Odyssey ODP-AGM34 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 21.10 kg and SAE terminals.

### Size, terminals and hold-down of the Odyssey ODP-AGM34

The Odyssey ODP-AGM34 is made in the 274 × 173 × 201 mm format and weighs 21.10 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### Why choose Odyssey batteries

Odyssey batteries combine starting and deep cycling in a single sealed pure-lead unit, with some of the longest warranties on the market. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Odyssey ODP-AGM34: ODP range and AGM technology

The ODP-AGM34 is part of the Odyssey **ODP** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.

### How to make it last longer

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.

### Warranty and coverage

The Odyssey ODP-AGM34 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.

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

Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

## Frequently asked questions

### Is the ODP-AGM34 model AGM? What does this technology offer?

Yes, it is AGM. In an AGM battery such as the ODP-AGM34, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better; it is the required technology for cars with advanced Start-Stop and regenerative braking.

### Is the Odyssey ODP-AGM34 battery suitable for Start-Stop?

Yes. It is a AGM battery of 61 Ah, designed for vehicles with Start-Stop. AGM batteries support advanced Start-Stop and regenerative braking thanks to their higher cycle count. Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the car manufacturer requires. Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start.

### How is the Odyssey ODP-AGM34 battery fitted in a Start-Stop car?

Start-Stop or BMS specifics: do not remove the IBS sensor on the negative terminal (just loosen the cable nut); after the swap, register the battery via OBD so the alternator charges with the right profile; and never step down in technology: if the car had AGM or EFB, the new one must be the same or better, as a conventional battery lasts only a few months. Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the left) to match the polarity; 6) connect the positive (+) and finally the negative (−). Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog.

### What is the service life of the ODP-AGM34 model?

Estimated lifespan of the Odyssey ODP-AGM34: 5 to 8 years in mild-climate car use with Start-Stop. Treat it as an approximate guide, as every case is different. What weighs most: temperature (cold makes starts harder and intense heat evaporates the electrolyte), frequent short trips, the condition of the alternator and charging system, power draw while parked and maintenance, not forgetting the type of car and Start-Stop.

### What are the dimensions of the Odyssey ODP-AGM34 battery?

The Odyssey ODP-AGM34 takes up 274×173×201 mm (length, width and height, terminals included). Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing.

### What polarity does the Odyssey ODP-AGM34 battery have?

The ODP-AGM34 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.

### Will the Odyssey ODP-AGM34 battery fit my car?

The ODP-AGM34 typically fits a wide range of European vehicles thanks to its standard DIN case format. Three routes: the "Compatible vehicles" tab on this page, with the vehicles verified by our technical team; your number plate in the finder, from which DGT/DVLA/KBA detect model and engine; and WhatsApp, with make, model, engine and year, during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables.

### What are the equivalents of the ODP-AGM34 model?

See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery. To replace the Odyssey ODP-AGM34 without modifications, the other battery must be identical in size, polarity, Ah and CCA.

### What advantages does the Odyssey ODP-AGM34 AGM battery offer over an EFB?

This ODP-AGM34 delivers 792 A cold cranking (EN). The absorbent glass-fibre mat of an AGM retains the electrolyte, so it cannot leak and withstands considerably more cycles than a conventional battery. Hence it is recommended for advanced Start-Stop with regenerative braking, such as BMW EfficientDynamics, Mercedes Eco, Audi MHEV, Land Rover ECO or Volvo i-Stop, and it handles tilting, vibration and extreme temperatures better than an EFB.

### Do I need to register the Odyssey ODP-AGM34 on the car after installation?

The alternator detects the new battery and adapts the charge automatically, so on most cars it is not compulsory. Even so, it is advisable to register it via OBD so charging is optimum from the first minute and the battery lasts longer, particularly on BMW, Mercedes, Audi, Volvo or Land Rover, with more sophisticated BMS. Any workshop with an OBD scanner does it in a few minutes; DIY, with VCDS or Carista (VAG group), Bimmercode (BMW) or iCarsoft. Even if you do not register the Odyssey ODP-AGM34, the car will start correctly; the profile adjusts within a few days.
