- Exide AGM12-12: 1 Ah more, 5 A less cranking power, a different height (145 mm instead of 110 mm). It only fits if there is room for 145 mm of height.
- Exide AGM12-12M: 1 Ah more, 5 A less cranking power, a different height (145 mm instead of 110 mm). It only fits if there is room for 145 mm of height.

## Check this before ordering the Exide ETZ14-BS

- Check the EN amps on your battery: if it says 205 A or less, the ETZ14-BS covers your engine.
- Your current battery should say about 11 Ah; a little more is also fine.
- Polarity of the ETZ14-BS: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- Length, width and height of the ETZ14-BS: 150 × 90 × 110 mm.

## Frequently asked questions about the Exide ETZ14-BS

Compared with the ETZ14-BS, the Exide ET12A-BS has 1 Ah less and 75 A less cranking power. The ETZ14-BS cranks harder; the ET12A-BS is only a good option if your original battery says 130 A or less. Mind the space: the ET12A-BS measures 150 × 90 × 105 mm.

### Exide ETZ14-BS or AGM12-12/AGM12-12M: what changes?

Mainly the height: the ETZ14-BS is 110 mm tall and the Exide AGM12-12 145 mm, with the same length and width.

### Which battery is equivalent to the Exide ETZ14-BS?

Only other AGM batteries with its dimensions and polarity: Varta TZ12S (FA), Varta TZ14S (FA) and Varta TTZ14S-BS. Neither an EFB nor a conventional battery replaces the ETZ14-BS.

### Which side is the positive terminal on the Exide ETZ14-BS?

On the ETZ14-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 ETZ14-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 ETZ14-BS is AGM

Inside, the ETZ14-BS has glass fibre separators (AGM) that hold the electrolyte. The ETZ14-BS needs a charger with an AGM mode that does not exceed 14.7 V.
