## Description

## Where the Kronobat MS-85.0 fits

The Kronobat MS-85.0 is a starter battery for cars without Start-Stop: it delivers the current the starter motor needs and then powers lights, control units and audio with the engine off. Its job is to start the engine in the cold with margin to spare and keep the car's electronics powered.
At 85 Ah it moves into large diesels, SUVs, vans and cars with heavy electrical equipment. The MS-85.0 belongs to the Kronobat SUPREME range. [The full range of Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)

The MS-85.0 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the MS-85.0 needs no special registration: just connect it.

## Check this before ordering the Kronobat MS-85.0

- If your car has Start-Stop, the MS-85.0 is not the right one: it needs an EFB or an AGM.
- Cold cranking: 800 A (EN), equal to or higher than the original.
- Capacity of the MS-85.0: 85 Ah; the same as your current battery or slightly more is fine.
- Polarity of the MS-85.0: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the MS-85.0 takes up 315 × 175 × 190 mm (European case size L4).

## Frequently asked questions about the Kronobat MS-85.0

### MS-85.0 or PB-80.0: which one suits me?

Compared with the MS-85.0, the Kronobat PB-80.0 has 5 Ah less and 60 A less cranking power. The MS-85.0 cranks harder; the PB-80.0 is only a good option if your original battery says 740 A or less. Both measure 315 × 175 × 190 mm, so they fit the same tray.

### Can the Kronobat MS-85.0 be used in a car with Start-Stop?

No. The MS-85.0 is a lead-acid battery for cars without automatic engine stop; Start-Stop needs an EFB or an AGM; in this same size there is the Kronobat PE-80-EFB.

### How much does the Kronobat MS-85.0 weigh?

19.6 kg, with 85 Ah of capacity. For reference, the Kronobat PB-80.0 (80 Ah) weighs 18.8 kg.

### Which battery is equivalent to the Kronobat MS-85.0?

With the same dimensions, polarity and similar capacity you have the Varta F19, Varta F16 and Exide EA900. As the MS-85.0 is a conventional battery, an EFB or AGM of the same size also works.

### What case size is the Kronobat MS-85.0?

Case size L4: 315 × 175 × 190 mm. The MS-85.0 fits any standard L4 battery tray such as the Varta F19.

### Which side is the positive terminal on the Kronobat MS-85.0?

On the MS-85.0, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Does the new battery need to be registered in the car?

In cars with energy management (common since 2010) it is worth registering the battery in the control unit so it adjusts charging. In older cars you just connect it.
