Car battery Kronobat SD-91.1T Standard 91Ah 740A 12V

The Kronobat SD-91.1T from the Standard range delivers 91 Ah and 740 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It replaces the original battery without adaptation in cars with a 306 × 173 × 225 mm format: same 91 Ah capacity and the positive terminal on the left.

In short: the Kronobat SD-91.1T (91 Ah, 740 A, 306 × 173 × 225 mm, positive terminal on the left). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size.

• Direct replacement for the original battery in size and terminals.
• Original-equipment build quality without the dealership price.
• Conventional lead-acid: the most proven and economical technology.
• Reliable cold starts, even after weeks without driving.

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.

The Kronobat SD-91.1T: Standard range and conventional lead-acid technology

The SD-91.1T 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.

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.

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. 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.

Official warranty

The Kronobat SD-91.1T 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.
