## Varta YB10L-B vs B10L (FA) and YTX14L-BS: which one to choose?

The real differences between the YB10L-B and the closest Varta models:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta YB10L-B (this one) | 11 Ah | 150 A | 136 × 91 × 146 | right | 3.94 kg |

| Varta YTX14L-BS | 12 Ah | 200 A | 150 × 87 × 146 | right | 4.37 kg |

- Varta B10L (FA): 1 Ah less, 30 A less cranking power, a different case (133 × 90 × 142 mm), AGM technology.
- Varta YTX14L-BS: 1 Ah more, 50 A more cranking power, a different case (150 × 87 × 146 mm), AGM technology.

## What to look at before buying the YB10L-B

- The YB10L-B needs 136 × 91 × 146 mm of space: measure it with the hold-down clamp in place.
- The YB10L-B has the positive terminal on the right: compare it with your current battery.
- With 11 Ah, the YB10L-B replaces an original battery of that capacity or slightly less.
- Cold cranking: 150 A (EN), equal to or higher than the original.

## Frequently asked questions about the Varta YB10L-B

### YB10L-B or B10L (FA): which one suits me?

Compared with the YB10L-B, the Varta B10L (FA) has 1 Ah less, 30 A less cranking power and AGM technology. The YB10L-B cranks harder; the B10L (FA) is only a good option if your original battery says 120 A or less. Mind the space: the B10L (FA) measures 133 × 90 × 142 mm.

### Is the Varta 511013015 the same battery as the Varta YB10L-B?

Yes. 511013015 is the ETN code Varta uses for its YB10L-B battery, so you can search for it by either code.

### How much does the Varta YB10L-B weigh?

3.94 kg, with 11 Ah of capacity. For reference, the Varta B10L (FA) (10 Ah) weighs 3.68 kg.

### Which battery is equivalent to the Varta YB10L-B?

With the same dimensions, polarity and similar capacity you have the Fulbat FB10L-BP and Varta YB10L-A2. As the YB10L-B is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Varta YB10L-B?

On the YB10L-B, 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.

## Inside the YB10L-B: lead-acid technology

Inside, the YB10L-B is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.
