The **Fulbat NS40 +D** battery is rated at **12 V**, **36 Ah** and **335 A** of cold cranking current (EN) and is designed for ride-on mowers, tillers and garden machinery. Its 195 × 126 × 221 mm and the positive terminal on the right make it the exact replacement for the 36 Ah battery fitted as standard to many ride-on mowers.
- Resistant to garden-engine vibration.
- Good balance of capacity, cranking power and price.
- Direct replacement for the original battery.
- Sealed and maintenance-free.

### What the Fulbat NS40 +D is for

The Fulbat NS40 +D is designed for ride-on mowers, tillers and garden machinery. After winter, a full charge before the first start avoids surprises.

### Technology inside the Fulbat NS40 +D

Within the Fulbat catalogue, the NS40 +D is the 36 Ah model designed for this application.
The conventional lead-acid battery remains the most widespread technology thanks to its balance of capacity, cranking current and price. Well maintained and kept charged, it offers years of reliable service in vehicles without Start-Stop.

### Will it fit your current battery tray?

The Fulbat NS40 +D is made in the 195 × 126 × 221 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. 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.

### Fulbat: the maker behind the NS40 +D

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.

### 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 NS40 +D 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.

### Delivery times and returns

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 do I fit the NS40 +D model in my truck?

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 many years does this battery last?

Expected lifespan of the Fulbat NS40 +D 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 NS40 +D battery?

Dimensions (length × width × height) are 195×126×221 mm — also written as 195x126x221 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 NS40 +D typically fits a wide range of European vehicles thanks to its standard DIN case format.

### Which batteries are equivalent to the Fulbat NS40 +D?

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.
