## Description

Starter batteries for ride-on mowers, such as Exide U1R-11 or U1-9, plus lithium batteries for cordless lawn mowers.

Ride-on mowers, garden tractors and other outdoor machines with electric start use small 12 V batteries that sit idle for months between seasons. Fit and terminal position are critical, since compartments are tight and cables short.
Compare each battery by dimensions, polarity, cranking current and construction, flooded or sealed AGM.

## Finding the right fit

Garden machinery uses a handful of common formats, often shared with motorcycles. Before choosing, check:
- **Dimensions** in mm, including height with terminals.
- **Polarity**: whether the positive terminal is on the left or right when facing them.
- **Capacity and CCA**: small single-cylinder engines need little current, larger twin-cylinder tractors noticeably more.
- **Terminal type**: bolt-on flat terminals or posts.

If your machine is a motorcycle-format fit, our [motorcycle battery](https://bateriasonline.es/en/motorcycle-batteries) section offers more alternatives with the same reference codes.

## Flooded or sealed

Many mowers came with flooded batteries that need occasional topping up with distilled water. A sealed AGM replacement avoids acid spills on a machine that tilts on slopes and is stored in sheds. Make sure the dimensions match, as sealed versions are sometimes slightly different. Vibration from the cutting deck also favours sealed construction. The [FULBAT](https://bateriasonline.es/en/fulbat-batteries) range includes batteries designed for garden equipment.

## Winter storage routine

The main cause of failure in garden batteries is the off-season. At the end of the mowing season, charge the battery fully. Disconnect it or remove it, and store it in a cool, dry place above freezing. Recharge it every couple of months or keep it on a smart maintainer. In spring, check voltage before the first start. A battery left discharged over winter sulphates and often cannot be recovered.

## Frequently asked questions

### My mower clicks but does not turn over. Is it the battery?

Often yes: a discharged battery or corroded terminals. Charge it and clean the contacts first; if the voltage drops sharply when cranking, the battery has reached the end of its life.

### Can I use a car charger on a small mower battery?

Only if it has a low-current or small-battery mode. High charging current overheats a small battery and shortens its life. A maintainer of around 1 A is enough for most garden batteries.
