## Frequently asked questions about the Fulbat FB5L-B

### FB5L-B or 12N5.5-3B: which one suits me?

Compared with the FB5L-B, the Fulbat 12N5.5-3B has 0.5 Ah more and 10 A less cranking power. The FB5L-B cranks harder; the 12N5.5-3B is only a good option if your original battery says 55 A or less. Mind the space: the 12N5.5-3B measures 135 × 60 × 130 mm.

### How much does the Fulbat FB5L-B weigh?

2.03 kg, with 5.3 Ah of capacity. For reference, the Fulbat 12N5.5-3B (5.8 Ah) weighs 2.27 kg.

### Which battery is equivalent to the Fulbat FB5L-B?

With the same dimensions, polarity and similar capacity you have the Exide EB5L-B and Varta YB5L-B. As the FB5L-B is a conventional battery, an EFB or AGM of the same size also works.

### Which side is the positive terminal on the Fulbat FB5L-B?

On the FB5L-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.

### Does the Fulbat FB5L-B come charged and ready to fit?

Sealed AGM and gel batteries leave the factory charged and ready. Conventional ones with a separate acid pack are activated when filled and should be charged before fitting.

## Lead-acid technology in the FB5L-B

Inside, the FB5L-B is classic lead-acid: liquid electrolyte and lead plates. If the FB5L-B is left discharged for weeks it sulphates: a maintenance charger prevents this.
