Frequently asked questions about the Varta M6

Varta M6 or M10?

Compared with the M6, the Varta M10 has 20 Ah more and 200 A more cranking power. If your current battery says 1,200 A or more, choose the M10; if it says 1,000 A or less, the M6 is enough. Both measure 513 × 223 × 223 mm, so they fit the same tray.

What does the code 670 043 100 on the Varta M6 mean?

It is its ETN (European Type Number), also written 670043100. The first three digits (670) encode voltage and capacity: 12 V and 170 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (043) identifies the specific model within that capacity, and the last three digits (100) multiplied by 10 give the cold cranking current: 1,000 A.

How much does the Varta M6 weigh?

The M6 weighs 43.93 kg. For reference, the Varta M10 (190 Ah) weighs 44.99 kg.

Which battery is equivalent to the Varta M6?

With the same dimensions, polarity and similar capacity you have the Exide EG1803, Kronobat SHD-180.3 and Tudor TG1803. As the M6 is a conventional battery, an EFB or AGM of the same size also works.

Which charger does the Varta M6 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.
