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 42 Ah C10 📏 Dimensions 196×165×169 mm ⚙️ Technology AGM 🧭 Polarity Positive on the right ⚖️ Weight 14,9 kg 🏷️ Model Genesis EP Pure lead ## Description ## Stationary battery Genesis G42EP EP Pure lead 42Ah 12V 12*V* Voltage 42*Ah* Capacity 14.90*kg* Weight The **12 V**, **42 Ah** **Genesis G42EP** stationary battery from the **EP Pure lead** range with AGM technology is designed for UPS, alarms, telecoms and emergency lighting. Measuring 196 × 165 × 169 mm and the positive terminal on the right, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 42 Ah battery of this format. - Low self-discharge and high reliability. - Standard format for UPS and emergency systems. - AGM: faster recharging and better cycle resistance than a conventional battery. - Instant response to mains failures. ### Will it fit your current battery tray? The Genesis G42EP is made in the 196 × 165 × 169 mm format and weighs 14.90 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses M6 hembra terminals, the system that anchors and connects it in the vehicle. 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. ### What the Genesis G42EP is for With 42 Ah, the Genesis G42EP 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 14.90 kg and M6 hembra terminals. ### The Genesis G42EP: EP Pure lead range and AGM technology The G42EP is part of the Genesis **EP Pure lead** range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family. 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. ### Why choose Genesis batteries Genesis EP batteries stand out for power density and reliability in industrial vehicles, boats and emergency systems. We guarantee that every Genesis arrives new, charged and with the manufacturer's full warranty. ### Manufacturer's warranty The Genesis G42EP 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. Check the float voltage of the UPS or charger: a voltage that is too high shortens the life of a sealed battery. ### When you get it and how to return it 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. You have **14 days** to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships. ## Frequently asked questions ### Is the G42EP model AGM? What does this technology offer? Yes: the G42EP from Genesis uses AGM (Absorbent Glass Mat) technology, a sealed lead-acid battery whose electrolyte soaks a glass-fibre mat. Compared with a conventional battery it withstands more charge/discharge cycles and handles heat better. ### What are the measurements of the G42EP model? Before buying, measure the space in your device: one extra millimetre can stop the hold-down clamp from closing. The Genesis G42EP takes up 197×165×170 mm (length, width and height, terminals included). ### What polarity does the Genesis G42EP battery have? Polarity of the Genesis G42EP: positive on the right. Seen from the front, terminals towards you, the positive (+) is the post with the red ring. Compare it with the battery you are replacing: if it does not match, cables must be lengthened or the system reconfigured, with a risk of short circuit. ## 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 · 2026-11-12*
