Practical advice for boats and motorhomes
A caravan with a motor mover asks for big bursts of current. Write the fitting date on each battery in the bank. Storing a bank half empty in the cold costs capacity that never comes back.

Questions and answers
Dimensions and weight of this model?
The case measures 278 × 175 × 190 mm and the battery weighs 16.82 kg. Check both against your tray and the hold-down before ordering, and lift it with care.
Is this enough battery for a cold start?
The cranking figure is 680A, measured to the EN standard, and the capacity is 74Ah. If your engine is large or you live somewhere cold, choose the higher end of what your vehicle allows.
What voltage and amp-hours does this model have?
Yes, 12V with 74Ah. Two in series would give double the voltage.
Does the Varta LFS74 have left or right-hand polarity?
Polarity here: positive on the right-hand side. Look at the unit in your vehicle too, as reversed polarity often leaves the cables too short.
Five checks for a perfect fit
- ✓ Check that the alternator or controller suits lead-acid.
- ✓ Dimensions to compare: 278 × 175 × 190 mm. Do not forget the base ledge, which the hold-down clamp grips on many vehicles.
- ✓ Note which corner the plus post occupies on your old unit. Here it is positive on the right-hand side, and crossed cables rarely reach.

About the technology: lead-acid
Wet lead batteries started engines long before the first motorway was built. Fleet vehicles often use flooded batteries for value. Store lead-acid batteries charged and recharge them every few months.
