Frequently asked questions about the Varta K11
K11 or J10: which one suits me?
Compared with the K11, the Varta J10 has 13 Ah less and 100 A more cranking power. If your current battery says 1,000 A or more, choose the J10; if it says 900 A or less, the K11 is enough. Mind the space: the J10 measures 514 × 175 × 210 mm.
What does the code 643 107 090 on the Varta K11 mean?
It is its ETN (European Type Number), also written 643107090. The first three digits (643) encode voltage and capacity: 12 V and 143 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (107) identifies the specific model within that capacity, and the last three digits (090) multiplied by 10 give the cold cranking current: 900 A.
How much does the Varta K11 weigh?
36.5 kg, with 143 Ah of capacity. For reference, the Varta J10 (130 Ah) weighs 35.46 kg.
Which battery is equivalent to the Varta K11?
With the same dimensions, polarity and similar capacity you have the Exide EG1402, Tudor TG1402 and Fulmen FG1402. As the K11 is a conventional battery, an EFB or AGM of the same size also works.
Which side is the positive terminal on the Varta K11?
On the K11, 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.
Are truck batteries fitted in pairs?
Almost always, in series for 24 V. Replace them in matched pairs: mixing a new one with an old one unbalances charging and shortens the new one's life.
