Size, terminals and hold-down of the Q-Battery 12LS-2.1
The Q-Battery 12LS-2.1 is made in the 178 × 35 × 60 mm format and weighs 1 kg. It uses a G112107 hold-down and F1 (4 75mm) 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 12LS-2.1
The 12LS-2.1 is one of the Q-Battery references for this type of use; it shares the same manufacturing and quality-control criteria as the rest of the brand's catalogue.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Q-Battery: the maker behind the 12LS-2.1
The Q-Battery catalogue runs from small alarm batteries to large traction monoblocs, always with sealed, maintenance-free technology. All the Q-Battery batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty.
Warranty and coverage
The Q-Battery 12LS-2.1 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.
How to make it last longer
Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
