With 41 Ah at 12 V and 360 A of cold cranking current (EN), the Kronobat SD-41.0B from the Standard range is a starter battery built for passenger cars with conventional starting, without a Start-Stop system. Its 207 × 175 × 175 mm and the positive terminal on the right make it the exact replacement for the 41 Ah battery fitted as standard to many cars.

In short: the Kronobat SD-41.0B (41 Ah, 360 A, 207 × 175 × 175 mm, positive terminal on the right). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size.

  • Stable voltage for the vehicle electronics (ECU, sensors, climate control).
  • Good balance of capacity, cranking power and price.
  • Designed to last several years under normal daily use.
  • Low self-discharge: copes with long stops without losing charge.

What the Kronobat SD-41.0B is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Kronobat SD-41.0B is the direct replacement when your vehicle uses a 41 Ah battery of this format. Before buying, compare dimensions, terminals and capacity with the battery you are replacing. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 10.90 kg and 1.0 terminals.

Size, terminals and hold-down of the Kronobat SD-41.0B

The Kronobat SD-41.0B is made in the 207 × 175 × 175 mm format and weighs 10.90 kg. 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. It uses 1.0 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Kronobat SD-41.0B: Standard range and conventional lead-acid technology

The Standard is the Kronobat range the SD-41.0B belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle.

In a conventional battery the electrolyte is liquid and the lead plates are immersed in it. It is a mature, economical and easily recycled technology, ideal for starting vehicles in normal use.

Kronobat: the maker behind the SD-41.0B

With Kronobat we offer an own-brand alternative without compromising on quality: European manufacturing, original-equipment controls and the direct backing of baterias.com for warranty and advice. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

Warranty and coverage

The Kronobat SD-41.0B comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.

Usage and maintenance tips

In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Keep the terminals clean and tight, and check that the resting voltage does not drop below 12.4 V: below that it is time to recharge.

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 do I change this battery step by step?

In most cars 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 right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On cars 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 SD-41.0B model?

Expected lifespan of the Kronobat SD-41.0B is 4 to 6 years in regular car 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 SD-41.0B model?

Dimensions (length × width × height) are 207×175×175 mm — also written as 207x175x175 mm and correspond to the European LB1 case size — following the European DIN standard. Always measure the space in your car before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.

What polarity does the Kronobat SD-41.0B battery have?

Polarity: positive on the right. 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.

Will the Kronobat SD-41.0B battery fit my car?

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 SD-41.0B typically fits a wide range of European vehicles thanks to its standard DIN case format.

Which interchangeable batteries are there for this one?

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