## Who the Kronobat MS-52.0 is for

The Kronobat MS-52.0 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.

At 52 Ah it covers petrol compacts and small diesels, the best-selling format in Europe. The MS-52.0 belongs to the Kronobat SUPREME range. [The full range of Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)

## Kronobat MS-52.0 vs PB-44.0B, MS-54.0 and PB-52.0: which one to choose?

Torn between the MS-52.0 and another similar Kronobat? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Kronobat MS-52.0 (this one) | 52 Ah | 520 A | 207 × 175 × 175 | right | 12.7 kg |
| Kronobat PB-44.0B | 44 Ah | 440 A | 207 × 175 × 175 | right | 11.5 kg |
| Kronobat MS-54.0 | 54 Ah | 530 A | 207 × 175 × 190 | right | 13.1 kg |
| Kronobat PB-52.0 | 52 Ah | 470 A | 207 × 175 × 190 | right | 12.7 kg |

- Kronobat MS-54.0: 2 Ah more, 10 A more cranking power, a different height (190 mm instead of 175 mm, L1). It only fits if there is room for 190 mm of height.
- Kronobat PB-52.0: the same capacity, 50 A less cranking power, a different height (190 mm instead of 175 mm, L1). It only fits if there is room for 190 mm of height.
- Kronobat SD-41.0B: 11 Ah less, 160 A less cranking power, the same LB1 case.

## Equivalents and alternatives to the Kronobat MS-52.0

Batteries that fit the MS-52.0's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the MS-52.0.

|---|---|---|---|---|
| Varta C6 | Lead-acid | 52 Ah | 520 A | 207 × 175 × 175 |

## What to look at before buying the MS-52.0

- The MS-52.0 needs 207 × 175 × 175 mm of space (European case size LB1): measure it with the hold-down clamp in place.
- The MS-52.0 has the positive terminal on the right: compare it with your current battery.
- Your current battery should say about 52 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 520 A or less, the MS-52.0 covers your engine.
- If your car has Start-Stop, the MS-52.0 is not the right one: it needs an EFB or an AGM.

## Lead-acid technology in the MS-52.0

The MS-52.0 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. Avoid leaving them discharged, as they sulphate, and charge them with a charger that cuts off or switches to maintenance when finished.
