Size, terminals and hold-down of the Q-Battery 6LS-12
It has external dimensions of 151 × 51 × 94 mm and weighs 2 kg. It uses a G112071 hold-down and F2 (6 35mm) terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

Technology inside the Q-Battery 6LS-12
Within the Q-Battery catalogue, the 6LS-12 is the 12 Ah model designed for this application.
AGM means the acid is held in a glass mat instead of floating free. That is why the battery can be installed in the cabin without gases, survives more cycles and recovers its charge quickly.
How to make it last longer
Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Replace all the batteries in the set at once and avoid environments continuously above 25 °C.
Warranty and coverage
The Q-Battery 6LS-12 comes with the manufacturer's official warranty against manufacturing defects. If it fails through a defect within the warranty period, we replace it at no cost to you.
