Frequently asked questions about the Varta I9

I9 or I18: which one suits me?

Compared with the I9, the Varta I18 has 10 Ah less and 100 A less cranking power. The I9 cranks harder; the I18 is only a good option if your original battery says 680 A or less. Both measure 349 × 175 × 236 mm, so they fit the same tray.

Varta I9 or J1: what changes?

Mainly the height: the I9 is 236 mm tall and the Varta J1 285 mm, with the same length and width. In capacity and cranking power, the J1 offers 125 Ah and 720 A against 120 Ah and 780 A. Before choosing between the I9 and the J1, measure the free height of the battery compartment with the cover or bonnet closed.

What does the code 620 047 078 on the Varta I9 mean?

It is its ETN (European Type Number), also written 620047078. The first three digits (620) encode voltage and capacity: 12 V and 120 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (047) identifies the specific model within that capacity, and the last three digits (078) multiplied by 10 give the cold cranking current: 780 A.

How much does the Varta I9 weigh?

29.01 kg, with 120 Ah of capacity. For reference, the Varta I18 (110 Ah) weighs 28.71 kg.

Which battery is equivalent to the Varta I9?

With the same dimensions, polarity and similar capacity you have the Exide EF1202, Tudor TF1202 and Fulmen FF1202. As the I9 is a conventional battery, an EFB or AGM of the same size also works.

Which side is the positive terminal on the Varta I9?

On the I9, 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 Varta I9 need?

An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.
