With 28 Ah and 300 A of cold cranking current (EN), the Fulbat U1R-9 Ca/Ca starts ride-on mowers, tillers and garden machinery after months of storage. It replaces the original battery without adaptation in ride-on mowers with a 195 × 130 × 180 mm format: same 28 Ah capacity and the positive terminal on the right.
- Compact format for small trays.
- Good tolerance to self-discharge.
- Conventional lead-acid: the most proven and economical technology.
- Reliable starting after months of winter storage.
What the Fulbat U1R-9 Ca/Ca is for
With 28 Ah, the Fulbat U1R-9 Ca/Ca starts ride-on mowers, tillers and garden machinery and copes with garden-engine vibration.
Technology inside the Fulbat U1R-9 Ca/Ca
Fulbat builds the U1R-9 Ca/Ca to the same standards as the rest of its catalogue; what changes between references is capacity, format and terminal position.
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?
In terms of format, the Fulbat U1R-9 Ca/Ca measures 195 × 130 × 180 mm (length × width × height). 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. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

How to change the battery
Guide to replace a truck battery in 30-60 minutes. Truck batteries weigh 25-50 kg — we recommend working in pairs and using a carrying strap.
Step 1. Prepare the vehicle
Park on a flat surface, switch off the engine and remove the key. Make sure all lights and electrical accessories are off. Wait 1-2 minutes before starting.
Step 2. Locate the battery
Open the bonnet. The battery is usually in the engine bay, but in many modern cars it may be in the boot or under the passenger seat. Check the manual if you cannot find it.
Step 3. Disconnect the negative (−) terminal
Use the 10 mm wrench to loosen the negative cable nut (black, marked −) and remove the cable from the post. Move it aside so it cannot touch any bodywork.
Step 4. Disconnect the positive (+) terminal
Repeat with the positive cable (red, marked +). Important: never let a terminal touch metal of the car while the other is still connected.
Step 5. Remove the old battery (two people)
Loosen the bottom hold-down clamp. Truck batteries weigh 25-50 kg — lift in pairs with gloves and a carrying strap. Forcing the lift alone risks back injury.
Step 6. Install the new battery
Place the battery in the same orientation as the old one (positive terminal on the same side). Tighten the hold-down clamp firmly.
Step 7. Connect the cables
Connect the positive (+) terminal first, then the negative (−). Tighten the nuts with the wrench until each terminal does not move. Apply anti-spark grease if you have any.
Step 8. Verify the engine starts
Close the bonnet. Start the engine to confirm everything works. On cars with Start-Stop or a BMS, you may need to register the battery via OBD so the alternator applies the correct charging profile.
Frequently asked questions
How is the Fulbat U1R-9 Ca/Ca 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-9 Ca/Ca battery last?
Expected lifespan of the Fulbat U1R-9 Ca/Ca 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 size is this battery?
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.
Is the U1R-9 Ca/Ca 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 U1R-9 Ca/Ca typically fits a wide range of European vehicles thanks to its standard DIN case format.
Which batteries are equivalent to the Fulbat U1R-9 Ca/Ca?
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.
