Long float-life under permanent charge and instant response to mains outages with no noticeable voltage drop. ## Why this stationary battery? - **Instant response** when the mains drop, no voltage dip - **Long life under 24/7 charge** optimised for permanent service - **Compatible with your system** existing UPS units and alarm control panels 🔌 Voltage 12 V ⚡ Capacity 45 Ah C20 📏 Dimensions 199×166×171 mm ⚙️ Technology AGM ⚖️ Weight 13,5 kg 🏷️ Model WXL Series ## Description ## Stationary battery Long WXL12150W WXL Series 45Ah 12V 12*V* Voltage 45*Ah* Capacity 13.50*kg* Weight The **Long WXL12150W** with AGM technology is a **45 Ah**, **12 V** backup battery for UPS, alarms, telecoms and emergency lighting. Its 199 × 166 × 171 mm make it the exact replacement for the 45 Ah battery fitted as standard to many UPS, alarm and emergency systems. - Standard format for UPS and emergency systems. - Low self-discharge and high reliability. - Instant response to mains failures. - AGM: faster recharging and better cycle resistance than a conventional battery. ### Dimensions, polarity and mounting In terms of format, the Long WXL12150W measures 199 × 166 × 171 mm (length × width × height) and weighs 13.50 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change. ### What the Long WXL12150W is for The Long WXL12150W is designed for UPS, alarms, telecoms and emergency lighting: it sits on float charge and responds instantly to a mains failure. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 13.50 kg. ### The Long WXL12150W: WXL Series range and AGM technology The WXL12150W is part of the Long **WXL Series** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Why choose Long batteries Long batteries combine large-scale production with ISO quality standards and a batch-to-batch consistency that has made them the de-facto standard in backup systems and electric mobility. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Long WXL12150W 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 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. ### When you get it and how to return it Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email. ## Frequently asked questions ### Is this battery AGM? What is it for? Yes, it is AGM. In an AGM battery such as the WXL12150W, the electrolyte is not free but absorbed in a glass-fibre mat inside a sealed lead-acid battery. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance. ### What are the dimensions of the Long WXL12150W battery? Check the room available in your device, because a single millimetre too much can stop the clamp from closing. Its dimensions are 199×166×171 mm, also written 199x166x171 mm; the height already includes the terminals. ### Long WXL12150W or Q-battery BATTERY-12LS-45: which one to choose? It has the same dimensions, voltage and technology as the WXL12150W, although it is not a manufacturer-approved equivalent. Compared with the WXL12150W it has the same Ah and cranking power. It costs €181.60 more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — automotive battery specialists since 2012. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-11-08*
