Before ordering the TTZ10S-BS, check this

  • Measure the space: the TTZ10S-BS takes up 150 × 87 × 93 mm.
  • The TTZ10S-BS has the positive terminal on the left: compare it with your current battery.
  • Your current battery should say about 8 Ah; a little more is also fine.
  • Check the EN amps on your battery: if it says 150 A or less, the TTZ10S-BS covers your engine.

Frequently asked questions about the Varta TTZ10S-BS

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

Compared with the TTZ10S-BS, the Varta TZ10S (FA) has 1 Ah more. With the same cranking power (150 A), the TTZ10S-BS and the TZ10S (FA) 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 TTZ10S-BS or YTX9-BS/YTX9 (FA): what changes?

Mainly the height: the TTZ10S-BS is 93 mm tall and the Varta YTX9-BS 106 mm, with the same length and width. In capacity and cranking power, the YTX9-BS offers 8 Ah and 135 A against 8 Ah and 150 A. The Varta YTX9 (FA) is 106 mm tall, with 8 Ah and 135 A. Before choosing between the TTZ10S-BS and the YTX9-BS, measure the free height of the battery compartment with the cover or bonnet closed.

Is the Varta 508901015 the same battery as the Varta TTZ10S-BS?

Yes. 508901015 is the ETN code Varta uses for its TTZ10S-BS battery, so you can search for it by either code.

How much does the Varta TTZ10S-BS weigh?

3.11 kg, with 8 Ah of capacity. For reference, the Varta TZ10S (FA) (9 Ah) weighs 3.15 kg.

Which battery is equivalent to the Varta TTZ10S-BS?

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

Which side is the positive terminal on the Varta TTZ10S-BS?

On the TTZ10S-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 Varta TTZ10S-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 TTZ10S-BS is AGM

Inside, the TTZ10S-BS has glass fibre separators (AGM) that hold the electrolyte. It is fitted in cars with advanced Start-Stop and in deep-cycle equipment.
