The Kronobat HD-125.0 with conventional lead-acid technology delivers 125 Ah at 12 V and 720 A of cold cranking current (EN): what trucks, buses, tractors and heavy machinery demand. Its 349 × 175 × 290 mm and the positive terminal on the right make it the exact replacement for the 125 Ah battery fitted as standard to many trucks.

  • Better tolerance to deep discharge than a conventional starter battery.
  • Powers tachograph, fridge and heater during rest stops.
  • Resistant to constant chassis vibration.
  • Good balance of capacity, cranking power and price.

What the Kronobat HD-125.0 is for

With 125 Ah, the Kronobat HD-125.0 cranks large-displacement diesel engines in the cold and powers tachograph, fridge and heater during rest stops. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 31.22 kg and 1.0 terminals.

The Kronobat HD-125.0: Promotive Standard range and conventional lead-acid technology

Within the Kronobat catalogue, the Promotive Standard series groups the references designed for this use. The HD-125.0 is the 125 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Dimensions, polarity and mounting

In terms of format, the Kronobat HD-125.0 measures 349 × 175 × 290 mm (length × width × height) and weighs 31.22 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.

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. We guarantee that every Kronobat arrives new, charged and with the manufacturer's full warranty.

Usage and maintenance tips

In 24 V installations, check periodically that both batteries show the same voltage; an imbalance means one is failing. During rest stops with active loads, avoid repeated deep discharges: they shorten the life of any starter battery.

Warranty and coverage

The Kronobat HD-125.0 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.

Delivery times and returns

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

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.

How long does the Kronobat HD-125.0 battery last?

Expected lifespan of the Kronobat HD-125.0 is 4 to 6 years in normal lorry use. 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 HD-125.0 model?

Dimensions (length × width × height) are 349×175×290 mm — also written as 349x175x290 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.

What polarity does the Kronobat HD-125.0 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 HD-125.0 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 HD-125.0 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 trucks. See the "Equivalents" section to view recommended options at the same performance level.
