  • Exide AGM12-5: 2 Ah less, 30 A less cranking power, the same dimensions.
  • Exide ETX7L-BS: the same capacity, the same cranking power, a different height (130 mm instead of 105 mm). It only fits if there is room for 130 mm of height.
  • Exide ETX5L-BS: 2 Ah less, 30 A less cranking power, the same dimensions.

What to look at before buying the ETZ7-BS

  • Measure the space: the ETZ7-BS takes up 115 × 70 × 105 mm.
  • The ETZ7-BS has the positive terminal on the right: compare it with your current battery.
  • Your current battery should say about 6 Ah; a little more is also fine.
  • The ETZ7-BS delivers 100 A cold cranking (EN standard); do not go below what your original battery states.

Frequently asked questions about the Exide ETZ7-BS

ETZ7-BS or AGM12-5: which one suits me?

Compared with the ETZ7-BS, the Exide AGM12-5 has 2 Ah less and 30 A less cranking power. The ETZ7-BS cranks harder; the AGM12-5 is only a good option if your original battery says 70 A or less. Both measure 115 × 70 × 105 mm, so they fit the same tray.

Exide ETZ7-BS or ETX7L-BS: what changes?

Mainly the height: the ETZ7-BS is 105 mm tall and the Exide ETX7L-BS 130 mm, with the same length and width. In capacity and cranking power, the ETX7L-BS offers 6 Ah and 100 A against 6 Ah and 100 A. Before choosing between the ETZ7-BS and the ETX7L-BS, measure the free height of the battery compartment with the cover or bonnet closed.

How much does the Exide ETZ7-BS weigh?

2.2 kg, with 6 Ah of capacity. For reference, the Exide AGM12-5 (4 Ah) weighs 1.8 kg.

Which battery is equivalent to the Exide ETZ7-BS?

Only other AGM batteries with its dimensions and polarity: Varta TZ7S (FA), Motobatt MBTZ7S and Exide AGM12-7. Neither an EFB nor a conventional battery replaces the ETZ7-BS.

Which side is the positive terminal on the Exide ETZ7-BS?

On the ETZ7-BS, 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.

Which charger does the Exide ETZ7-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.

AGM technology in the ETZ7-BS

The ETZ7-BS is AGM: the electrolyte is absorbed in glass fibre mats, so it is sealed and spill-proof. Being sealed, the ETZ7-BS can be fitted in the boot or under a seat with no risk of spills.
