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. - 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? Tool: a 10 mm spanner. Time: 15-30 minutes on almost every car, and up to double if the battery is not under the bonnet but in the boot or under a seat. Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog. The right order: engine off and key out; disconnect the negative (−) first, then the positive (+); release the hold-down clamp, lift out the old battery and seat the new one in the same position (positive on the right), keeping the polarity; reconnect the positive (+) first and the negative (−) last. ### What is the service life of the SD-41.0B model? Estimated lifespan of the Kronobat SD-41.0B: 4 to 6 years in regular car use without Start-Stop. Treat it as an approximate guide, as every case is different. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count. ### What are the measurements of the SD-41.0B model? Its dimensions are 207×175×175 mm, also written 207x175x175 mm; the height already includes the terminals. In European terms it is a LB1 case. Check the room available in your car, because a single millimetre too much can stop the clamp from closing. ### What polarity does the Kronobat SD-41.0B battery have? The SD-41.0B has the positive on the right in a LB1 case: that is its polarity. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering. ### Will the Kronobat SD-41.0B battery fit my car? The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the car manufacturer states in the owner's handbook. ### Which interchangeable batteries are there for this one? Technology matters too: in Start-Stop cars, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the SD-41.0B, 41 Ah (360 A cranking). ### Kronobat SD-41.0B or Varta A17: which one to choose? It is the verified Varta equivalent for the SD-41.0B tray. Compared with the SD-41.0B it has the same Ah and cranking power. It costs 18,60 € more. Decide by price, brand preference and availability: both fit and crank the same. ## Equivalent batteries - [VARTA A17](https://baterias.com/gb/battery-varta-a17-12v-41ah-360a) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-07*
