- Exide AGM12-10.5: 1 Ah more, 40 A more cranking power, a different case (150 × 70 × 130 mm).
- Exide ET12B-BS: 1 Ah more, 40 A more cranking power, a different case (150 × 70 × 130 mm).

## Check this before ordering the Exide ETX9C-BS

- Measure the space: the ETX9C-BS takes up 135 × 75 × 140 mm.
- With the terminals facing you, the positive terminal of the ETX9C-BS is on the left.
- With 9 Ah, the ETX9C-BS replaces an original battery of that capacity or slightly less.
- Check the EN amps on your battery: if it says 120 A or less, the ETX9C-BS covers your engine.

## Frequently asked questions about the Exide ETX9C-BS

### ETX9C-BS or AGM12-10.5: which one suits me?

Compared with the ETX9C-BS, the Exide AGM12-10.5 has 1 Ah more and 40 A more cranking power. If your current battery says 160 A or more, choose the AGM12-10.5; if it says 120 A or less, the ETX9C-BS is enough. Mind the space: the AGM12-10.5 measures 150 × 70 × 130 mm.

### How much does the Exide ETX9C-BS weigh?

3.2 kg, with 9 Ah of capacity. For reference, the Exide AGM12-10.5 (10 Ah) weighs 3.6 kg.

### Which battery is equivalent to the Exide ETX9C-BS?

Only other AGM batteries with its dimensions and polarity: Fulbat FT9A-BS and Exide AGM12-9. Neither an EFB nor a conventional battery replaces the ETX9C-BS.

### Which side is the positive terminal on the Exide ETX9C-BS?

On the ETX9C-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.

### Which charger does the Exide ETX9C-BS need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.

## What it means that the ETX9C-BS is AGM
