## Description

## Where the Kronobat PE-65-EFB fits

The Kronobat PE-65-EFB is a battery for cars with Start-Stop: it withstands many more starting and partial-discharge cycles than a conventional battery and powers the electronics every time the engine stops at the lights. In a Start-Stop car, the PE-65-EFB keeps the radio, climate control and lights running with the engine off without losing capacity.
At 65 Ah it is the usual size for compact diesels and mid-size petrol saloons. The PE-65-EFB belongs to the Kronobat PREMIUM EFB range. [The full range of Kronobat batteries](https://bateriasonline.es/en/kronobat-batteries)

- With the terminals facing you, the positive terminal of the PE-65-EFB is on the right.
- With 65 Ah, the PE-65-EFB replaces an original battery of that capacity or slightly less.
- Check the EN amps on your battery: if it says 650 A or less, the PE-65-EFB covers your engine.
- The PE-65-EFB is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.

## What it means that the PE-65-EFB is EFB

## Frequently asked questions about the Kronobat PE-65-EFB

### PE-65-EFB or PE-72-EFB: which one suits me?

Compared with the PE-65-EFB, the Kronobat PE-72-EFB has 7 Ah more and 110 A more cranking power. If your current battery says 760 A or more, choose the PE-72-EFB; if it says 650 A or less, the PE-65-EFB is enough. Mind the space: the PE-72-EFB measures 261 × 175 × 220 mm.

### Can the Kronobat PE-65-EFB be used in a car with Start-Stop?

Yes, the PE-65-EFB is an EFB: it suits Start-Stop without brake energy recovery, or cars that already had an EFB. If your car left the factory with an AGM, fit another AGM.

### How much does the Kronobat PE-65-EFB weigh?

18.4 kg, with 65 Ah of capacity. For reference, the Kronobat PE-72-EFB (72 Ah) weighs 20.7 kg.

### Which battery is equivalent to the Kronobat PE-65-EFB?

In EFB or AGM, with its dimensions and polarity: Varta N65. A conventional battery does not replace the PE-65-EFB.

### What case size is the Kronobat PE-65-EFB?

Case size D23: 232 × 175 × 225 mm. The PE-65-EFB fits any standard D23 battery tray such as the Varta N65.

### Which side is the positive terminal on the Kronobat PE-65-EFB?

On the PE-65-EFB, 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.

### Can I fit the Kronobat PE-65-EFB if my car came with an AGM battery?

Only if the PE-65-EFB is AGM. A car that leaves the factory with AGM must always run AGM; an EFB in its place will not last and may trigger dashboard warnings.
