## Frequently asked questions about the Fulbat FB9-B

### Fulbat FB9-B or FT9A-BS?

Compared with the FB9-B, the Fulbat FT9A-BS has AGM technology. With the same 9.5 Ah and 115 A, the difference is the technology. Choose the FT9A-BS if your car left the factory with AGM; if it had lead-acid, either will do. Both measure 135 × 75 × 139 mm, so they fit the same tray.

### What is the difference between the Fulbat FB9-B and the FB9L-B?

They are the same battery with the terminals swapped: positive terminal on the left on the FB9-B, positive terminal on the right on the FB9L-B. Look at your current battery with the terminals facing you and pick the one that matches.

### How much does the Fulbat FB9-B weigh?

The FB9-B weighs 2.91 kg. For reference, the Fulbat FT9A-BS (9.5 Ah) weighs 2.87 kg.

### Which battery is equivalent to the Fulbat FB9-B?

With the same dimensions, polarity and similar capacity you have the Exide AGM12-9, Exide ETX9C-BS and Fulbat FT9A-BS. As the FB9-B is a conventional battery, an EFB or AGM of the same size also works.

## What it means that the FB9-B is lead-acid

Inside, the FB9-B is classic lead-acid: liquid electrolyte and lead plates. If the FB9-B is left discharged for weeks it sulphates: a maintenance charger prevents this.
