## Description

## Lawn mower battery Fulbat U1R-12 SLA 32Ah 400A 12V

12*V* Voltage
32*Ah* Capacity
400*A* Cold cranking

The **Fulbat U1R-12 SLA** battery is rated at **12 V**, **32 Ah** and **400 A** of cold cranking current (EN) and is designed for ride-on mowers, tillers and garden machinery. Measuring 195 × 125 × 176 mm and the positive terminal on the right, it is the direct replacement for ride-on mowers fitted from the factory with a 32 Ah battery of this format.
- Sealed and maintenance-free.
- Direct replacement for the original battery.
- AGM: faster recharging and better cycle resistance than a conventional battery.
- Resistant to garden-engine vibration.

### What the Fulbat U1R-12 SLA is for

The Fulbat U1R-12 SLA is designed for ride-on mowers, tillers and garden machinery. After winter, a full charge before the first start avoids surprises.

### Dimensions, polarity and mounting

The Fulbat U1R-12 SLA is made in the 195 × 125 × 176 mm format. 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. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

### Fulbat: the maker behind the U1R-12 SLA

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

### Technology inside the Fulbat U1R-12 SLA

Fulbat builds the U1R-12 SLA to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.

### Usage and maintenance tips

Disconnect or remove the battery over winter and give it a maintenance charge before storing it. Check the voltage before the first start of the season and clean the terminals.

### Manufacturer's warranty

The Fulbat U1R-12 SLA 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

Order **before [[ks:cutoff]]** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **[[ks:return_days]] days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### How is the Fulbat U1R-12 SLA 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 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 trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.

### How long does the Fulbat U1R-12 SLA battery last?

Expected lifespan of the Fulbat U1R-12 SLA is 4 to 7 years in regular use (depends on technology and climate). 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 Fulbat U1R-12 SLA battery?

Dimensions (length × width × height) are 195×125×176 mm — also written as 195x125x176 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.

### Does this battery fit my truck?

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 U1R-12 SLA typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Fulbat U1R-12 SLA?

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.
