Kronobat HD-125.0 · Truck battery 12V 125Ah 720A

Truck battery Kronobat HD-125.0 Promotive Standard 125Ah 720A 12V

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.
