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 πŸ”Œ Voltage 12 V ⚑ Capacity 2 Ah C20 πŸ“ Dimensions 178Γ—34Γ—66 mm βš™οΈ Technology AGM βš–οΈ Weight 0,87 kg 🏷️ Model WPS Series ## Description ## Stationary battery Long WPS2.3-12 WPS Series 2.3Ah 12V 12*V* Voltage 2.3*Ah* Capacity 0.87*kg* Weight Designed for UPS, alarms, telecoms and emergency lighting, the **Long WPS2.3-12** from the **WPS Series** range offers **2.3 Ah** with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 178 Γ— 34 Γ— 66 mm format: same 2.3 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 WPS2.3-12 is for The Long WPS2.3-12 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 0.87 kg. ### The Long WPS2.3-12: WPS Series range and AGM technology Within the Long catalogue, the **WPS Series** series groups the references designed for this use. The WPS2.3-12 is the 2.3 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. ### Dimensions, polarity and mounting It has external dimensions of 178 Γ— 34 Γ— 66 mm and weighs 0.87 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 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. ### How to make it last longer Replace all the batteries in the set at once and avoid environments continuously above 25 Β°C. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### Manufacturer's warranty The Long WPS2.3-12 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 Order **before [[ks:cutoff]]** 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 **[[ks:return_days]] 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 the WPS2.3-12 model AGM? What does this technology offer? Yes. The WPS2.3-12 from Long uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for devices with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions. ### How do I fit the WPS2.3-12 model in my device? In most devices it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (βˆ’) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation β€” match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (βˆ’). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### What is the service life of the WPS2.3-12 model? Expected lifespan of the Long WPS2.3-12 is 5 to 8 years in mild-climate device use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the dimensions of the Long WPS2.3-12 battery? Dimensions (length Γ— width Γ— height) are 178Γ—35Γ—66 mm β€” also written as 178x35x66 mm β€” following the European DIN standard. Always measure the space in your device before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Which interchangeable batteries are there for this one? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology β€” an EFB cannot be replaced with a conventional battery in Start-Stop devices. See the "Equivalents" section to view recommended options at the same performance level. ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team β€” over 25 years of experience validating automotive batteries. β†’ https://baterias.com/gb/technical-team --- *baterias.com β€” Automotive batteries Β· 2026-10-03*
