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 8 Ah C20 📏 Dimensions 151×65×102 mm ⚙️ Technology AGM ⚖️ Weight 2,5 kg 🏷️ Model WPS Series ## Description ## Stationary battery Long WP1234W WPS Series 8.5Ah 12V 12*V* Voltage 8.5*Ah* Capacity 2.50*kg* Weight The **12 V**, **8.5 Ah** **Long WP1234W** stationary battery from the **WPS Series** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 151 × 65 × 102 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 8.5 Ah battery of this format. - AGM: faster recharging and better cycle resistance than a conventional battery. - Instant response to mains failures. - Low self-discharge and high reliability. - Standard format for UPS and emergency systems. ### What the Long WP1234W is for Designed for UPS, alarms, telecoms and emergency lighting, the Long WP1234W 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 2.50 kg. ### Dimensions, polarity and mounting It has external dimensions of 151 × 65 × 102 mm and weighs 2.50 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 Long does differently Long (Kung Long Batteries) is one of the world's largest manufacturers of sealed VRLA batteries. Its AGM and GEL series for UPS, mobility, alarms and cycling are found in equipment worldwide as original equipment. We guarantee that every Long arrives new, charged and with the manufacturer's full warranty. ### The Long WP1234W: WPS Series range and AGM technology Within the Long catalogue, the **WPS Series** series groups the references designed for this use. The WP1234W is the 8.5 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### How to make it last longer 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. ### Manufacturer's warranty The Long WP1234W 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. ### Delivery times and returns Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### Is the Long WP1234W an AGM battery and what are the benefits of AGM? Yes. The Long WP1234W is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. It withstands more cycles than a conventional battery and copes better with heat. ### What are the dimensions of the Long WP1234W battery? Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 151×65×102 mm in length × width × height, with the terminals included in the height. ## 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 · 2026-11-07*
