  • Varta TTZ10S-BS: 1 Ah less, the same cranking power, the same dimensions.
  • Varta YTX12-BS: 1 Ah more, the same cranking power, a different height (131 mm instead of 93 mm). It only fits if there is room for 131 mm of height.
  • Varta T12A (FA): 1 Ah more, 5 A less cranking power, a different height (105 mm instead of 93 mm). It only fits if there is room for 105 mm of height.
  • Varta YTX7A-4 (FA): 3 Ah less, 45 A less cranking power, the same dimensions.

What to look at before buying the TZ10S (FA)

  • The TZ10S (FA) needs 150 × 87 × 93 mm of space: measure it with the hold-down clamp in place.
  • With the terminals facing you, the positive terminal of the TZ10S (FA) is on the left.
  • Your current battery should say about 9 Ah; a little more is also fine.
  • Cold cranking: 150 A (EN), equal to or higher than the original.

Frequently asked questions about the Varta TZ10S (FA)

TZ10S (FA) or TTZ10S-BS: which one suits me?

Compared with the TZ10S (FA), the Varta TTZ10S-BS has 1 Ah less. With the same cranking power (150 A), the TZ10S (FA) and the TTZ10S-BS differ in capacity: the one with more Ah supports more load with the engine off. Both measure 150 × 87 × 93 mm, so they fit the same tray.

Varta TZ10S (FA) or YTX12-BS/T12A (FA): what changes?

Mainly the height: the TZ10S (FA) is 93 mm tall and the Varta YTX12-BS 131 mm, with the same length and width. In capacity and cranking power, the YTX12-BS offers 10 Ah and 150 A against 9 Ah and 150 A. The Varta T12A (FA) is 105 mm tall, with 10 Ah and 145 A. Before choosing between the TZ10S (FA) and the YTX12-BS, measure the free height of the battery compartment with the cover or bonnet closed.

Is the Varta 508909015 the same battery as the Varta TZ10S (FA)?

Yes. 508909015 is the ETN code Varta uses for its TZ10S (FA) battery, so you can search for it by either code.

3.15 kg, with 9 Ah of capacity. For reference, the Varta TTZ10S-BS (8 Ah) weighs 3.11 kg.

Which battery is equivalent to the Varta TZ10S (FA)?

Only other AGM batteries with its dimensions and polarity: Exide ETZ10-BS, Exide AGM12-8 and Varta TTZ10S-BS. Neither an EFB nor a conventional battery replaces the TZ10S (FA).

Which side is the positive terminal on the Varta TZ10S (FA)?

On the TZ10S (FA), 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.
