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 9 Ah C20 πŸ“ Dimensions 151Γ—65Γ—106 mm βš™οΈ Technology AGM βš–οΈ Weight 2,7 kg 🏷️ Model WP WATT Series ## Description ## Stationary battery Long WP1236WT WP WATT Series 9Ah 12V 12*V* Voltage 9*Ah* Capacity 2.70*kg* Weight The **12 V**, **9 Ah** **Long WP1236WT** stationary battery from the **WP WATT Series** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. It measures 151 Γ— 65 Γ— 106 mm, the format sought by anyone replacing a 9 Ah battery in UPS, alarm and emergency systems. - Maintenance-free for its whole service life. - Sealed and gas-free: suitable for cabinets and offices. - Long float life under permanent charge. - AGM technology: absorbed electrolyte, no spills, can be mounted at an angle. ### What the Long WP1236WT is for With 9 Ah, the Long WP1236WT 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. ### Size, terminals and hold-down of the Long WP1236WT The Long WP1236WT is made in the 151 Γ— 65 Γ— 106 mm format and weighs 2.70 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. ### The Long WP1236WT: WP WATT Series range and AGM technology The WP1236WT is part of the Long **WP WATT 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. 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. ### Why choose Long batteries 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. All the Long batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Manufacturer's warranty The Long WP1236WT 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### 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 WP1236WT an AGM battery and what are the benefits of AGM? Yes. The WP1236WT 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 is the Long WP1236WT battery installed in the vehicle? 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 WP1236WT model? Expected lifespan of the Long WP1236WT 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 WP1236WT battery? Dimensions (length Γ— width Γ— height) are 151Γ—65Γ—106 mm β€” also written as 151x65x106 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 batteries are equivalent to the Long WP1236WT? 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· 2026-09-28*
