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 2,7 kg 🏷️ Model WPL Series ## Description ## Stationary battery Long WPL1235W WPL Series 8.5Ah 12V 12*V* Voltage 8.5*Ah* Capacity 2.70*kg* Weight The **12 V**, **8.5 Ah** **Long WPL1235W** stationary battery from the **WPL Series** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 151 × 65 × 102 mm format: same 8.5 Ah capacity. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. - Long float life under permanent charge. - Sealed and gas-free: suitable for cabinets and offices. - Maintenance-free for its whole service life. ### What the Long WPL1235W is for Designed for UPS, alarms, telecoms and emergency lighting, the Long WPL1235W 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 2.70 kg. ### Dimensions, polarity and mounting The Long WPL1235W is made in the 151 × 65 × 102 mm format and weighs 2.70 kg. 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. ### The Long WPL1235W: WPL Series range and AGM technology The **WPL Series** is the Long range the WPL1235W belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. 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. ### Long: the maker behind the WPL1235W 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. ### Manufacturer's warranty The Long WPL1235W 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. ### Care and maintenance 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. ### Delivery times and returns Orders placed **before 6:00 pm** with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days.

The Long WPL1235W is AGM (Absorbent Glass Mat): sealed lead-acid, with the electrolyte absorbed in glass fibre. Its advantages: more charge/discharge cycles than a conventional battery and better heat tolerance. ### What are the measurements of the WPL1235W model? 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*
