Measuring 170 × 72 × 208 mm, it is the direct replacement for UPS, alarm and emergency systems fitted from the factory with a 100 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. ### Dimensions, polarity and mounting In terms of format, the Long MSK100A measures 170 × 72 × 208 mm (length × width × height) and weighs 7.50 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### What the Long MSK100A is for The Long MSK100A 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 7.50 kg. ### The Long MSK100A: MSK Series range and AGM technology Within the Long catalogue, the **MSK Series** series groups the references designed for this use. The MSK100A is the 100 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. ### What Long does differently 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 MSK100A 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 the MSK100A model AGM? What does this technology offer? Yes. The MSK100A 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 measurements of the MSK100A model? Dimensions (length × width × height) are 170×72×208 mm — also written as 170x72x208 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 · 2026-11-03*
