## Quick description

The Varta K7 (ETN 645 400 080, also written K 7 or 645400080) is a truck battery with 12 V, 145 Ah and 800 A cold cranking current, measuring 513 × 189 × 223 mm.

## Description

## Where the Varta K7 fits

The Varta K7 is a starter battery for trucks, tractors and machinery: high capacity, robust terminals and a build that withstands vibration and the starts of large engines. With 145 Ah, the K7 suits heavy vehicles that had a battery of that capacity.
Varta lists the K7 in its Promotive SLI line. [See all Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Lead-acid technology in the K7

The K7 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.

## Varta K7 vs K8 and M11

How the K7 compares with Varta batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Weight |
|---|---|---|---|---|
| Varta K7 (this one) | 145 Ah | 800 A | 513 × 189 × 223 | 37.12 kg |
| Varta K8 | 140 Ah | 800 A | 513 × 189 × 223 | 34.76 kg |
| Varta M11 | 154 Ah | 1,150 A | 513 × 189 × 223 | 39.84 kg |

- Varta K8: 5 Ah less, the same cranking power, the same dimensions.
- Varta M11: 9 Ah more, 350 A more cranking power, the same dimensions.

## Equivalents and alternatives to the Varta K7

Batteries that fit the K7's tray with the same polarity; besides other conventional batteries, an EFB or AGM of this size is a valid upgrade for the K7.

## Before ordering the K7, check this

- Check the EN amps on your battery: if it says 800 A or less, the K7 covers your engine.
- Capacity of the K7: 145 Ah; the same as your current battery or slightly more is fine.
- The K7 needs 513 × 189 × 223 mm of space: measure it with the hold-down clamp in place.

## Frequently asked questions about the Varta K7

### K7 or K8: which one suits me?

Compared with the K7, the Varta K8 has 5 Ah less. With the same cranking power (800 A), the K7 and the K8 differ in capacity: the one with more Ah supports more load with the engine off. Both measure 513 × 189 × 223 mm, so they fit the same tray.

### What does the code 645 400 080 on the Varta K7 mean?

It is its ETN (European Type Number), also written 645400080. The first three digits (645) encode voltage and capacity: 12 V and 145 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (400) identifies the specific model within that capacity, and the last three digits (080) multiplied by 10 give the cold cranking current: 800 A.

### How much does the Varta K7 weigh?

37.12 kg, with 145 Ah of capacity. For reference, the Varta K8 (140 Ah) weighs 34.76 kg.

### Which battery is equivalent to the Varta K7?

With the same dimensions, polarity and similar capacity you have the Kronobat SHD-145.3, Exide EG1403 and Kronobat HD-140.3. As the K7 is a conventional battery, an EFB or AGM of the same size also works.

### What does HD or vibration resistance mean on a truck battery?

That the plates are fixed to withstand intense vibration (EN 50342 V3/V4). It is essential in construction, agriculture and long-haul transport.
