Compared with the LFS52, the Varta LA50 has 2 Ah less, 70 A more cranking power and AGM technology. If your current battery says 540 A or more, choose the LA50; if it says 470 A or less, the LFS52 is enough. Both measure 207 × 175 × 190 mm, so they fit the same tray.

What is the ETN code of the Varta LFS52?

930052047, also written 930 052 047. The ETN (European Type Number) is printed on the label and used in parts catalogues.

How much does the Varta LFS52 weigh?

12.02 kg, with 52 Ah of capacity. For reference, the Varta LA50 (50 Ah) weighs 14.72 kg.

Which battery is equivalent to the Varta LFS52?

With the same dimensions, polarity and similar capacity you have the Exide EN500 and Varta LA50. As the LFS52 is a conventional battery, an EFB or AGM of the same size also works.

What case size is the Varta LFS52?

Case size L1: 207 × 175 × 190 mm (Varta lists it as H4/L1). The LFS52 fits any standard L1 battery tray such as the Exide EN500.

Which side is the positive terminal on the Varta LFS52?

On the LFS52, 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.

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.
