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 9 Ah C20 📏 Dimensions 151×65×102 mm ⚙️ Technology AGM ⚖️ Weight 2,7 kg 🏷️ Model WP WATT Series ## Description ## Stationary battery Long WP1236W WP WATT Series 9Ah 12V 12*V* Voltage 9*Ah* Capacity 2.70*kg* Weight Designed for UPS, alarms, telecoms and emergency lighting, the **Long WP1236W** from the **WP WATT Series** range offers **9 Ah** with AGM technology on permanent float charge. It replaces the original battery without adaptation in UPS, alarm and emergency systems with a 151 × 65 × 102 mm format: same 9 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. ### Will it fit your current battery tray? The Long WP1236W is made in the 151 × 65 × 102 mm format and weighs 2.70 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Long WP1236W is for With 9 Ah, the Long WP1236W gives your UPS or emergency system the autonomy it needs. Replace all the batteries in the set at once. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.70 kg. ### The Long WP1236W: WP WATT Series range and AGM technology Within the Long catalogue, the **WP WATT Series** series groups the references designed for this use. The WP1236W is the 9 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Long: the maker behind the WP1236W 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. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty. ### Warranty and coverage The Long WP1236W 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 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. ### Shipping, delivery 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 Long WP1236W an AGM battery and what are the benefits of AGM? Yes. The WP1236W 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 WP1236W 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 (−) 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 — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On devices with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Long WP1236W battery last? Expected lifespan of the Long WP1236W 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 measurements of the WP1236W model? Dimensions (length × width × height) are 151×65×102 mm — also written as 151x65x102 mm — 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 batteries are equivalent to the Long WP1236W? 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 — 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. ## Reviews - **Average rating**: 4.76 / 5 (53 reviews) ## Technical team (editorial authorship) The FAQs, guides and comparisons on this site are reviewed by the baterias.com technical team — over 25 years of experience validating automotive batteries. → https://baterias.com/gb/technical-team --- *baterias.com — Automotive batteries · 2026-09-30*
