## Description

## Lawn mower battery Fulbat U1-9 25.3Ah 240A 12V

12*V* Voltage
25.3*Ah* Capacity
240*A* Cold cranking

The **Fulbat U1-9** with conventional lead-acid technology delivers **25.3 Ah** at **12 V** and **240 A** of cold cranking current (EN) for ride-on mowers, tillers and garden machinery. It measures 195 × 130 × 180 mm and the positive terminal on the left, the format sought by anyone replacing a 25.3 Ah battery in ride-on mowers.
- Reliable starting after months of winter storage.
- Conventional lead-acid: the most proven and economical technology.
- Good tolerance to self-discharge.
- Compact format for small trays.

### What the Fulbat U1-9 is for

With 25.3 Ah, the Fulbat U1-9 starts ride-on mowers, tillers and garden machinery and copes with garden-engine vibration.

### Technology inside the Fulbat U1-9

Within the Fulbat catalogue, the U1-9 is the 25.3 Ah model designed for this application.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.

### Will it fit your current battery tray?

The Fulbat U1-9 is made in the 195 × 130 × 180 mm format. 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. 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.

### What Fulbat does differently

French brand Fulbat is a European reference in motorcycle, garden and leisure batteries: compact ranges, clear JIS codes and a consistent quality that workshops know well. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Usage and maintenance tips

Check the voltage before the first start of the season and clean the terminals. On batteries with filler caps, check the electrolyte level and top up only with distilled water.

### Warranty and coverage

The Fulbat U1-9 comes with the **manufacturer's official warranty** against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.

### 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

### How is the Fulbat U1-9 battery installed in the vehicle?

In most trucks 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 our blog. 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 — with positive on the left match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### What is the service life of the U1-9 model?

Expected lifespan of the Fulbat U1-9 is 4 to 6 years in regular truck use without 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 are the measurements of the U1-9 model?

Dimensions (length × width × height) are 195×130×180 mm — also written as 195x130x180 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

### What polarity does the Fulbat U1-9 battery have?

Polarity: positive on the left. 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.

### Is the U1-9 valid for my vehicle?

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 U1-9 typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Fulbat U1-9?

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