## Description

**Find the battery for your lawnmower** using the finder right below: select your vehicle step by step and see only 100% compatible batteries.
Other quick paths: by [number plate](/gb/battery-finder-by-plate), by [part-number](/gb/part-number) from the manufacturer or by the **code printed** on your current battery (Varta E11, Tudor TC700, YTX12-BS, etc.).

## How to choose the right mower battery

Lawn tractors sit idle **5-7 months a year**. Conventional flooded lead-acid can lose 50% over that time. **AGM with low self-discharge** is preferable; connect a maintainer for storage.

### Typical capacities

### Compatibility and how to choose correctly

Before buying, check the original battery's **capacity (Ah)**, **polarity** and **case dimensions** against the manufacturer's manual. If you're unsure between two AGM models for your John Deere, Husqvarna or Stiga, use the [comparison tool](/gb/comparator) to see capacity, CCA and price side by side before deciding.

## Frequently asked questions about mower batteries

### **How long does a lawn tractor battery last?**

It mainly depends on off-season care: an AGM kept on a maintainer during idle months lasts noticeably longer than one left to self-discharge unattended, since prolonged self-discharge is the main cause of premature sulphation.

### **How do I stop it going flat over winter?**

Connect a 12V maintainer when storing the tractor at season's end, or fully charge it before disconnecting the terminals. That avoids finding a dead battery come spring.

### **Can I fit any 12V AGM battery to my mower?**

Not just any one: match the minimum capacity, polarity and case size specified by the manufacturer (John Deere, Husqvarna, Stiga, MTD, Toro...). A lower-Ah battery may crank poorly in cold weather.

### **Do robotic mowers use the same battery as ride-on tractors?**

No. Robots such as Honda Miimo carry dedicated, non-interchangeable lithium packs (LiFePO4 or Li-ion), while ride-on lawn tractors use standard 12V lead-acid AGM batteries.
