Compared with the LFS105N, the Varta LAD115 has 10 Ah more, 250 A less cranking power and AGM technology. The LFS105N cranks harder; the LAD115 is only a good option if your original battery says 550 A or less. Mind the space: the LAD115 measures 328 × 172 × 233.5 mm.

### What is the ETN code of the Varta LFS105N?

930105080, also written 930 105 080. The ETN (European Type Number) is printed on the label and used in parts catalogues.

### How much does the Varta LFS105N weigh?

24.67 kg, with 105 Ah of capacity. For reference, the Varta LAD115 (115 Ah) weighs 32.8 kg.

### Which battery is equivalent to the Varta LFS105N?

With the same dimensions, polarity and similar capacity you have the Varta LFS105M, Exide EP900 and Exide EM960. As the LFS105N is a conventional battery, an EFB or AGM of the same size also works.

### How do I look after the boat battery in winter?

Leave it 100% charged, disconnected or on a marine maintenance charger. A battery that spends the winter half-discharged loses capacity permanently.
