The **Kronobat SD-91.0T car battery** is rated at **12 V**, **91 Ah** and **740 A** of cold cranking current (EN) from the **Standard** range, and is designed for passenger cars with conventional starting, without a Start-Stop system. It measures 306 × 173 × 225 mm and the positive terminal on the right, the format sought by anyone replacing a 91 Ah battery in cars.
- Original-equipment build quality without the dealership price.
- Direct replacement for the original battery in size and terminals.
- Reliable cold starts, even after weeks without driving.
- Conventional lead-acid: the most proven and economical technology.

### What the Kronobat SD-91.0T is for

Designed for passenger cars with conventional starting, without a Start-Stop system, the Kronobat SD-91.0T is the direct replacement when your vehicle uses a 91 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 21.70 kg and 1.0 terminals.

### The Kronobat SD-91.0T: Standard range and conventional lead-acid technology

The SD-91.0T is part of the Kronobat **Standard** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
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.

### Dimensions, polarity and mounting

It has external dimensions of 306 × 173 × 225 mm and weighs 21.70 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. 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.

### What Kronobat does differently

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.

### How to make it last longer

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. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.

### Manufacturer's warranty

The Kronobat SD-91.0T 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.

### Delivery times and returns

Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

## Frequently asked questions

### How is the Kronobat SD-91.0T battery installed in the vehicle?

Steps: 1) switch off and remove the key; 2) find the battery (bonnet, boot or under a seat); 3) undo the negative (−), then the positive (+); 4) remove the clamp and the old battery; 5) fit the new one facing the same way (positive on the right) to match the polarity; 6) connect the positive (+) and finally the negative (−). Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. Before you start, check the car handbook: the manufacturer's procedure always comes first. Our full step-by-step guide is on the blog.

### How many years does this battery last?

Estimated lifespan of the Kronobat SD-91.0T: 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 size is this battery?

Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 306x173x225 mm. Height is measured to the top of the terminals.

### On which side is the positive of the SD-91.0T model?

The SD-91.0T has the positive on the right: that is its polarity. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.

### Does this 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)). If our table and the car handbook disagree, go with what the manufacturer says.

### Which batteries are equivalent to the Kronobat SD-91.0T?

Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives. Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the SD-91.0T, 91 Ah (740 A cranking).

### Kronobat SD-91.0T or Kronobat PB-95.0T: which one to choose?

It has the same dimensions, voltage and technology as the SD-91.0T, although it is not a manufacturer-approved equivalent. Compared with the SD-91.0T it has 4 Ah more and 90 A of cold cranking more. It costs 2,60 € more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.

### Kronobat SD-91.0T or Varta G7: which one to choose?

It has the same dimensions, voltage and technology as the SD-91.0T, although it is not a manufacturer-approved equivalent. Compared with the SD-91.0T it has 4 Ah more and 90 A of cold cranking more. It costs 13,60 € more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
