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 120 Ah C20 📏 Dimensions 408×177×224 mm ⚙️ Technology AGM ⚖️ Weight 37 kg 🏷️ Model HTP Series ## Description ## Stationary battery Long HTP120-12N HTP Series 120Ah 12V 12*V* Voltage 120*Ah* Capacity 37*kg* Weight The **12 V**, **120 Ah** **Long HTP120-12N** stationary battery from the **HTP Series** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 408 × 177 × 224 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 120 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 HTP120-12N is for With 120 Ah, the Long HTP120-12N 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 37 kg. ### Will it fit your current battery tray? The Long HTP120-12N is made in the 408 × 177 × 224 mm format and weighs 37 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Long HTP120-12N: HTP Series range and AGM technology Within the Long catalogue, the **HTP Series** series groups the references designed for this use. The HTP120-12N is the 120 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 HTP120-12N 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. ### Official warranty The Long HTP120-12N 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 Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. Replace all the batteries in the set at once and avoid environments continuously above 25 °C. ### When you get it and how to return it Order **before 6:00 pm** 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 **14 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 this battery AGM? What is it for? Yes. The HTP120-12N 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. ### What are the dimensions of the Long HTP120-12N battery? Dimensions (length × width × height) are 408×177×224 mm — also written as 408x177x224 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. ## 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 · 2026-10-29*
