## Description

## Motorcycle battery Odyssey ODS-AGM30E ODS 34Ah 400A

34*Ah* Capacity
400*A* Cold cranking
9.10*kg* Weight

With **34 Ah** at ** V** and **400 A** of cold cranking current (EN), the **Odyssey ODS-AGM30E** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It measures 249 × 97 × 155 mm and the positive terminal on the right, the format sought by anyone replacing a 34 Ah battery in motorcycles.
- Same JIS code as the original battery: fits first time.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
- Energetic cranking for high-compression engines.
- Resistant to the vibration typical of two wheels.

### What the Odyssey ODS-AGM30E is for

Designed for motorcycles, scooters, quads and personal watercraft, the Odyssey ODS-AGM30E replaces the original battery of bikes that use this code or format. Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 9.10 kg and M6 Stud terminals.

### Size, terminals and hold-down of the Odyssey ODS-AGM30E

In terms of format, the Odyssey ODS-AGM30E measures 249 × 97 × 155 mm (length × width × height) and weighs 9.10 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses M6 Stud 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.

### 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. We guarantee that every Odyssey arrives new, charged and with the manufacturer's full warranty.

### The Odyssey ODS-AGM30E: ODS range and AGM technology

The **ODS** is the Odyssey range the ODS-AGM30E 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 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.

### Care and maintenance

Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute.

### Manufacturer's warranty

The Odyssey ODS-AGM30E comes with the **manufacturer's official warranty**. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger.

### Delivery times and returns

Same-day dispatch from our warehouse for in-stock orders placed **before [[ks:cutoff]]**: 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 **[[ks:return_days]] 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 Odyssey ODS-AGM30E an AGM battery and what are the benefits of AGM?

Yes. The ODS-AGM30E 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 motorcycles with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.

### How is the Odyssey ODS-AGM30E battery installed in the vehicle?

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

### How long does the Odyssey ODS-AGM30E battery last?

Expected lifespan of the Odyssey ODS-AGM30E is 5 to 8 years in mild-climate motorcycle 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 249×97×155 mm — also written as 249x97x155 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### Does this battery fit my motorcycle?

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 ODS-AGM30E typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Odyssey ODS-AGM30E?

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 motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
