What the Q-Battery 12LS-55 is for

With 55 Ah, the Q-Battery 12LS-55 gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18 kg and F11 (M6) terminals.

Size, terminals and hold-down of the Q-Battery 12LS-55

The Q-Battery 12LS-55 is made in the 229 × 138 × 210 mm format and weighs 18 kg. It uses F11 (M6) 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-55

The 12LS-55 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.

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.

Care and maintenance

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.
