## Equivalents and alternatives to the Varta YB9L-B

Same dimensions and polarity as the YB9L-B, with similar capacity and cranking power; as a conventional battery, the YB9L-B can also be replaced by an EFB or AGM of the same size if you want more cycles.

| Model | Technology | Capacity | Cold cranking (EN) | Dimensions (mm) |
|---|---|---|---|---|
| Exide 12N9-3B | Lead-acid | 9 Ah | 85 A | 135 × 75 × 140 |

## Varta YB9L-B vs YB9L-A2, YB9-B and YB7L-B

The real differences between the YB9L-B and the closest Varta models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta YB9L-B (this one) | 9 Ah | 85 A | 136 × 76 × 140 | right | 2.98 kg |
| Varta YB9L-A2 | 9 Ah | 130 A | 135 × 75 × 139 | right | 3.19 kg |
| Varta YB9-B | 9 Ah | 85 A | 136 × 76 × 139 | left | 2.98 kg |
| Varta YB7L-B | 7 Ah | 74 A | 136 × 76 × 134 | right | 2.85 kg |

- Varta YB9L-A2: the same capacity, 45 A more cranking power, the same dimensions.
- If the positive terminal of your battery is on the other side, the one you need is the Varta YB9-B (positive terminal on the left).
- Varta YB7L-B: 2 Ah less, 11 A less cranking power, a different case (136 × 76 × 134 mm).

## Check this before ordering the Varta YB9L-B

- Check the EN amps on your battery: if it says 85 A or less, the YB9L-B covers your engine.
- Your current battery should say about 9 Ah; a little more is also fine.
- The YB9L-B has the positive terminal on the right: compare it with your current battery.
- Length, width and height of the YB9L-B: 136 × 76 × 140 mm.

## Frequently asked questions about the Varta YB9L-B

### Varta YB9L-B or YB9L-A2?

Compared with the YB9L-B, the Varta YB9L-A2 has 45 A more cranking power. If your current battery says 130 A or more, choose the YB9L-A2; if it says 85 A or less, the YB9L-B is enough. Both measure 136 × 76 × 140 mm, so they fit the same tray.

### What is the difference between the Varta YB9L-B and the YB9-B?

They are the same battery with the terminals swapped: positive terminal on the right on the YB9L-B, positive terminal on the left on the YB9-B. Look at your current battery with the terminals facing you and pick the one that matches. That is why their ETNs only differ in the middle group: 509 015 009 for the YB9L-B and 509 014 009 for the YB9-B.

### Is the Varta 509015009 the same battery as the Varta YB9L-B?

Yes. 509015009 is the ETN code Varta uses for its YB9L-B battery, so you can search for it by either code.

### How much does the Varta YB9L-B weigh?

The YB9L-B weighs 2.98 kg. For reference, the Varta YB9L-A2 (9 Ah) weighs 3.19 kg.

### Which battery is equivalent to the Varta YB9L-B?

With the same dimensions, polarity and similar capacity you have the Exide 12N9-3B. As the YB9L-B is a conventional battery, an EFB or AGM of the same size also works.

### Which charger does the Varta YB9L-B need?

An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.

## Lead-acid technology in the YB9L-B

Inside, the YB9L-B is classic lead-acid: liquid electrolyte and lead plates. If the YB9L-B is left discharged for weeks it sulphates: a maintenance charger prevents this.
