Stationary battery Q-Battery 12LS-18 18Ah 12V

The 12 V, 18 Ah Q-Battery 12LS-18 stationary battery with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 181 × 77 × 167 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 18 Ah battery of this format.

In short: the Q-battery 12LS-18 (18 Ah, 181 × 77 × 167 mm). Verified equivalent alternatives: Ritar RT12180 and Q-battery 12LS-17.

• Low self-discharge and high reliability.
• Standard format for UPS and emergency systems.
• AGM: faster recharging and better cycle resistance than a conventional battery.
• Instant response to mains failures.

Dimensions, polarity and mounting

In terms of format, the Q-Battery 12LS-18 measures 181 × 77 × 167 mm (length × width × height) and weighs 5.70 kg. It uses a G112074 hold-down and F3 (flag) 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.

What the Q-Battery 12LS-18 is for

Designed for UPS, alarms, telecoms and emergency lighting, the Q-Battery 12LS-18 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 5.70 kg, F3 (flag) terminals and G112074 hold-down.

Technology inside the Q-Battery 12LS-18

The 12LS-18 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.

Why choose Q-Battery batteries

Q-Battery specialises in AGM and GEL VRLA batteries for UPS, telecoms, solar and deep cycling, with long-life and tubular-plate series for industrial use. We guarantee that every Q-Battery arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Q-Battery 12LS-18 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.

Usage and maintenance tips

Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.

Shipping, delivery and returns

Orders placed before 6:00 pm with the battery in stock ship the same day.
