Fitting and everyday care

A family estate loaded for the holidays leans on its battery the moment the engine starts. If the car does mostly short hops, a smart charger once a month makes a real difference. A battery that needs a jump after a weekend parked has lost too much capacity.

Make sure it fits your vehicle or equipment

  • ✓ Same box, opposite posts? Many sizes exist in both layouts. This one is positive on the left-hand side.
  • ✓ Stored energy reserve: 44Ah. Going much lower than your current battery can leave you short on cold mornings or long stops.
  • ✓ Check the EN figure on your old label against 730A.
