Check the position of the positive terminal before ordering. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 2.60 kg. ### The Motobatt YTX7LBS-YTZ8V: Quadflex range and AGM technology The **Quadflex** is the Motobatt range the YTX7LBS-YTZ8V belongs to: it shares the same construction and quality criteria with the rest of the series, and varies in capacity and format to suit each vehicle. 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. ### Size, terminals and hold-down of the Motobatt YTX7LBS-YTZ8V It has external dimensions of 114 × 70 × 128 mm and weighs 2.60 kg. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### Why choose Motobatt batteries Motobatt batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty. ### Care and maintenance If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Avoid repeated cranking attempts on a cold bike for long: if it does not start on the third try, let the battery rest for a minute. ### Official warranty The Motobatt YTX7LBS-YTZ8V comes with the **manufacturer's official warranty**. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger. ### Delivery times and returns 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 ### How should this motorcycle battery be charged? With a 12 V motorcycle charger delivering at most 10 % of its capacity: 0.8 A for its 8 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### How long does the Motobatt YTX7LBS-YTZ8V battery last? As a guide, you can expect the Motobatt YTX7LBS-YTZ8V to last 3 to 5 years, keeping it charged when the bike is not in use, although the real figure may be higher or lower. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance. ### What are the measurements of the YTX7LBS-YTZ8V model? Measure your motorcycle's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 114x70x128 mm. Height is measured to the top of the terminals. ### Is the YTX7LBS-YTZ8V valid for my vehicle? For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). If our table and the motorcycle handbook disagree, go with what the manufacturer says. ### What are the equivalents of the YTX7LBS-YTZ8V model? A battery interchangeable with the Motobatt YTX7LBS-YTZ8V must match it on dimensions (114×70×128 mm), polarity, capacity (8 Ah) and cranking current (115 A). The options at the same level are in the "Equivalents" section of this page. ## 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*
