### ET7B-BS or AGM12-6.5: which one suits me?

Compared with the ET7B-BS, the Exide AGM12-6.5 has 0.5 Ah less. With the same cranking power (85 A), the ET7B-BS and the AGM12-6.5 differ in capacity: the one with more Ah supports more load with the engine off. Both measure 150 × 65 × 95 mm, so they fit the same tray.

### How much does the Exide ET7B-BS weigh?

2.4 kg, with 7 Ah of capacity. For reference, the Exide AGM12-6.5 (6.5 Ah) weighs 2.3 kg.

### Which battery is equivalent to the Exide ET7B-BS?

Only other AGM batteries with its dimensions and polarity: Varta T7B (FA), Motobatt MB7U and Exide AGM12-7F. Neither an EFB nor a conventional battery replaces the ET7B-BS.

### Which side is the positive terminal on the Exide ET7B-BS?

On the ET7B-BS, the positive terminal is on the left with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.

### Does the Exide ET7B-BS 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.
