## Deta DK950 vs DK960 and DK1050

How the DK950 compares with Deta batteries of similar size and capacity:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Deta DK950 (this one) | 95 Ah | 850 A | 353 × 175 × 190 | right | 25.9 kg |
| Deta DK960 | 96 Ah | 850 A | 353 × 175 × 190 | right | 26.1 kg |
| Deta DK1050 | 105 Ah | 950 A | 392 × 175 × 190 | right | 29 kg |

- Deta DK960: 1 Ah more, the same cranking power, the same L5 case.
- Deta DK1050: 10 Ah more, 100 A more cranking power, a different case (392 × 175 × 190 mm).

## Equivalents and alternatives to the Deta DK950

## AGM technology in the DK950

Inside, the DK950 has glass fibre separators (AGM) that hold the electrolyte. The DK950 needs a charger with an AGM mode that does not exceed 14.7 V.

## What to look at before buying the DK950

- The DK950 is AGM: it replaces an AGM or an EFB of the same size. You can swap an EFB for an AGM, but not an AGM for an EFB.
- The DK950 delivers 850 A cold cranking (EN standard); do not go below what your original battery states.
- With 95 Ah, the DK950 replaces an original battery of that capacity or slightly less.
- Polarity of the DK950: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the DK950 takes up 353 × 175 × 190 mm (European case size L5).

## Frequently asked questions about the Deta DK950

### Deta DK950 or DK960?

Compared with the DK950, the Deta DK960 has 1 Ah more. With the same cranking power (850 A), the DK950 and the DK960 differ in capacity: the one with more Ah supports more load with the engine off. Both measure 353 × 175 × 190 mm, so they fit the same tray.

### Can the Deta DK950 be used in a car with Start-Stop?

Yes. As an AGM battery, the DK950 handles automatic engine stop and brake energy recovery, and it can replace an EFB of the same size.

### How much does the Deta DK950 weigh?

The DK950 weighs 25.9 kg. For reference, the Deta DK960 (96 Ah) weighs 26.1 kg.

### Which battery is equivalent to the Deta DK950?

Only other AGM batteries with its dimensions and polarity: Varta A5, Fulmen FK950 and Exide EK960. Neither an EFB nor a conventional battery replaces the DK950.

### What case size is the Deta DK950?

Case size L5: 353 × 175 × 190 mm. The DK950 fits any standard L5 battery tray such as the Varta A5.

### Which side is the positive terminal on the Deta DK950?

The DK950 has the positive terminal on the right, looking at the battery from its long side with the terminals closest to you.

### Which charger does the Deta DK950 need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.
