What the Q-Battery 12LS-250 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-250 is sealed, gas-free and suitable for technical cabinets and offices. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 77 kg and F12 (M8) terminals.

Technology inside the Q-Battery 12LS-250

Within the Q-Battery catalogue, the 12LS-250 is the 250 Ah model designed for this application.

AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.

Size, terminals and hold-down of the Q-Battery 12LS-250

The Q-Battery 12LS-250 is made in the 521 × 268 × 220 mm format and weighs 77 kg. It uses F12 (M8) 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.
