### What the Kronobat SHD-145.3 is for

The Kronobat SHD-145.3 is designed for trucks, buses, tractors and heavy machinery. In 24 V installations with two batteries in series, replace both at the same time to avoid imbalance. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 37 kg and 1.0 terminals.

### The Kronobat SHD-145.3: Promotive Premium range and conventional lead-acid technology

The **Promotive Premium** is the Kronobat range the SHD-145.3 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.

### Size, terminals and hold-down of the Kronobat SHD-145.3

It has external dimensions of 513 × 189 × 223 mm and weighs 37 kg. The positive terminal on the left 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.

### What Kronobat does differently

Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### Usage and maintenance tips

On batteries with filler caps, check the electrolyte level and top up only with distilled water. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.

### Manufacturer's warranty

The Kronobat SHD-145.3 comes with the **manufacturer's official warranty** against manufacturing defects. An important note for commercial vehicles: most trucks use **two batteries connected in series** (24 V installation). If you replace only one, the new battery works alongside the old one, which has already lost capacity; that imbalance shortens its life and the manufacturer may treat it as misuse. Always replace **both at the same time**.

### When you get it and how to return it

Order **before 6:00 pm** 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 **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### Why does my lorry have two batteries?

Most lorries, buses and tractors run on 24 V with two 12 V batteries connected in series. Always replace both at the same time and with the same model: if one is new and the other old, they become unbalanced and both last less.

### What is the service life of the SHD-145.3 model?

As a guide, you can expect the Kronobat SHD-145.3 to last 4 to 6 years in normal lorry use, although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of truck and whether it has Start-Stop.

### What are the dimensions of the Kronobat SHD-145.3 battery?

The Kronobat SHD-145.3 takes up 513×189×223 mm (length, width and height, terminals included). Before buying, measure the space in your truck: one extra millimetre can stop the hold-down clamp from closing.

### Which side is the positive terminal on this battery?

On the Kronobat SHD-145.3, the polarity is positive on the left. 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). To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring.

### Does this battery fit my truck?

For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The truck manufacturer's specifications always take priority over our tables.

### Which batteries are equivalent to the Kronobat SHD-145.3?

Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the SHD-145.3, 145 Ah (800 A cranking). Technology matters too: in Start-Stop trucks, an EFB cannot be replaced with a conventional battery. The options at the same level are in the "Equivalents" section of this page.

### Kronobat SHD-145.3 or Kronobat HD-140.3: which one to choose?

Same case and same technology as the SHD-145.3: an alternative by size, not an official equivalent. Compared with the SHD-145.3 it has 5 Ah less. It costs 61,60 € less. If the polarity matches and your truck had a similar capacity, it works as a replacement; if in doubt, ask us with your model.

### Kronobat SHD-145.3 or Varta K7: which one to choose?

It has the same dimensions, voltage and technology as the SHD-145.3, although it is not a manufacturer-approved equivalent. Compared with the SHD-145.3 it has the same Ah and cranking power. It costs 36,20 € less. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.
