Stationary battery Q-Battery 12LS-2.9 2.9Ah 12V

The Q-Battery 12LS-2.9 with AGM technology is a 2.9 Ah, 12 V backup battery for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 79 × 56 × 99 mm format: same 2.9 Ah capacity.

• Sealed and gas-free: suitable for cabinets and offices.
• Maintenance-free for its whole service life.
• AGM technology: absorbed electrolyte, no spills, can be mounted at an angle.
• Long float life under permanent charge.

What the Q-Battery 12LS-2.9 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-2.9 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 1.05 kg and F1 (4 75mm) terminals.

Dimensions, polarity and mounting

The Q-Battery 12LS-2.9 is made in the 79 × 56 × 99 mm format and weighs 1.05 kg. It uses 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-2.9

Within the Q-Battery catalogue, the 12LS-2.9 is the 2.9 Ah model designed for this application.

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.

Care and maintenance

Replace all the batteries in the set at once and avoid environments continuously above 25 °C. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery.
