## Description

## Who the Varta YB12A-A is for

The Varta YB12A-A is a motorcycle starter battery: compact, vibration-resistant and with just the right power to turn the starter motor and feed the electronics. It is worth keeping the YB12A-A on a maintenance charger if the bike is laid up over winter.
At 12 Ah it covers mid-capacity motorcycles, large scooters and light quads. Varta lists the YB12A-A in its Powersports SLI Freshpack line. [The full range of Varta batteries](https://bateriasonline.es/en/varta-batteries)

## Equivalents and alternatives to the Varta YB12A-A

Same dimensions and polarity as the YB12A-A, with similar capacity and cranking power; as a conventional battery, the YB12A-A 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 EB12A-A | Lead-acid | 12 Ah | 165 A | 135 × 80 × 160 |
| Fulbat FB12A-A | Lead-acid | 12.6 Ah | 155 A | 134 × 80 × 160 |

## Varta YB12A-A vs B12A (FA), YB12AL-A2 and TX14AH (FA): which one to choose?

Torn between the YB12A-A and another similar Varta? This is what changes:

| Model | Capacity | Cold cranking (EN) | Dimensions (mm) | Positive | Weight |
|---|---|---|---|---|---|
| Varta YB12A-A (this one) | 12 Ah | 160 A | 136 × 82 × 161 | left | 4.18 kg |
| Varta B12A (FA) | 12 Ah | 125 A | 134 × 81 × 160 | left | 3.88 kg |
| Varta YB12AL-A2 | 12 Ah | 160 A | 136 × 82 × 161 | right | 4.18 kg |
| Varta TX14AH (FA) | 12 Ah | 210 A | 133 × 90 × 164 | left | 4.4 kg |

- Varta B12A (FA): the same capacity, 35 A less cranking power, the same dimensions, AGM technology.
- If the positive terminal of your battery is on the other side, the one you need is the Varta YB12AL-A2 (positive terminal on the right).
- Varta TX14AH (FA): the same capacity, 50 A more cranking power, a different case (133 × 90 × 164 mm), AGM technology.

## Check this before ordering the Varta YB12A-A

- Check the EN amps on your battery: if it says 160 A or less, the YB12A-A covers your engine.
- Your current battery should say about 12 Ah; a little more is also fine.
- Polarity of the YB12A-A: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Length, width and height of the YB12A-A: 136 × 82 × 161 mm.

## Frequently asked questions about the Varta YB12A-A

### Varta YB12A-A or B12A (FA)?

Compared with the YB12A-A, the Varta B12A (FA) has 35 A less cranking power and AGM technology. The YB12A-A cranks harder; the B12A (FA) is only a good option if your original battery says 125 A or less. Both measure 136 × 82 × 161 mm, so they fit the same tray.

### What is the difference between the Varta YB12A-A and the YB12AL-A2?

They are the same battery with the terminals swapped: positive terminal on the left on the YB12A-A, positive terminal on the right on the YB12AL-A2. 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: 512 011 016 for the YB12A-A and 512 013 016 for the YB12AL-A2.

### Is the Varta 512011016 the same battery as the Varta YB12A-A?

Yes. 512011016 is the ETN code Varta uses for its YB12A-A battery, so you can search for it by either code.

### How much does the Varta YB12A-A weigh?

The YB12A-A weighs 4.18 kg. For reference, the Varta B12A (FA) (12 Ah) weighs 3.88 kg.

### Which battery is equivalent to the Varta YB12A-A?

With the same dimensions, polarity and similar capacity you have the Exide EB12A-A, Fulbat FB12A-A and Fulbat FB12A-B. As the YB12A-A is a conventional battery, an EFB or AGM of the same size also works.

### Which charger does the Varta YB12A-A 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.

## Inside the YB12A-A: lead-acid technology

The YB12A-A 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.
