## Description

## Motorcycle battery Odyssey ODS-AGM42LMJ ODS 42Ah 540A

42*Ah* Capacity
540*A* Cold cranking
18.40*kg* Weight

With **42 Ah** at **V** and **540 A** of cold cranking current (EN), the **Odyssey ODS-AGM42LMJ** with AGM technology replaces the original battery of motorcycles, scooters, quads and personal watercraft. It measures 201 × 170 × 165 mm and the positive terminal on the right, the format sought by anyone replacing a 42 Ah battery in motorcycles.
- Energetic cranking for high-compression engines.
- Resistant to the vibration typical of two wheels.
- Same JIS code as the original battery: fits first time.
- AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.

### What the Odyssey ODS-AGM42LMJ is for

With 42 Ah, the Odyssey ODS-AGM42LMJ covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18.40 kg and M6 Receptacle terminals.

### Size, terminals and hold-down of the Odyssey ODS-AGM42LMJ

It has external dimensions of 201 × 170 × 165 mm and weighs 18.40 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 Receptacle terminals, the system that anchors and connects it in the vehicle. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.

### The Odyssey ODS-AGM42LMJ: ODS range and AGM technology

The **ODS** is the Odyssey range the ODS-AGM42LMJ 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.

### 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. All the Odyssey batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.

### Official warranty

The Odyssey ODS-AGM42LMJ 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.

### How to make it last longer

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. 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 6:00 pm** 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 **14 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 ODS-AGM42LMJ model AGM? What does this technology offer?

Yes. The ODS-AGM42LMJ 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 should this motorcycle battery be charged?

With a 12 V motorcycle charger delivering at most 10 % of its capacity: 4.2 A for its 42 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger.

### Does it need maintenance?

No: being AGM, it is sealed and nothing needs topping up. Just keep it charged if the bike stands for a long time.

### How many years does this battery last?

Expected lifespan of the Odyssey ODS-AGM42LMJ is 4 to 6 years, keeping it charged when the bike is not in use. 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 ODS-AGM42LMJ battery?

Dimensions (length × width × height) are 201×170×165 mm — also written as 201x170x165 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.

### On which side is the positive of the ODS-AGM42LMJ model?

Polarity: positive on the right. 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 ODS-AGM42LMJ 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 16:30–18:00 (Spanish time, CET)). The ODS-AGM42LMJ typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Odyssey ODS-AGM42LMJ?

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.
