It has external dimensions of 71 × 71 × 96 mm and weighs 0.73 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. ### What the Motobatt MBT6N4 is for With 4 Ah, the Motobatt MBT6N4 covers the starting of motorcycles, scooters, quads and personal watercraft. The JIS code on your current battery label is the safest way to confirm equivalence. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 0.73 kg. ### The Motobatt MBT6N4: Quadflex range and AGM technology Within the Motobatt catalogue, the **Quadflex** series groups the references designed for this use. The MBT6N4 is the 4 Ah model of that family, with the same performance as its siblings in other sizes. 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. ### Motobatt: the maker behind the MBT6N4 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. All the Motobatt batteries in our catalogue are genuine product, recently manufactured and covered by the manufacturer's warranty. ### Warranty and coverage The Motobatt MBT6N4 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. ### Usage and maintenance tips 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. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators. ### When you get it and how to return it Same-day dispatch from our warehouse for in-stock orders placed **before 6:00 pm**: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for **14 days** if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email. ## Frequently asked questions ### How should this motorcycle battery be charged? With a 6 V motorcycle charger delivering at most 10 % of its capacity: 0.5 A for its 4 Ah. High-current car chargers can damage it. If the bike is laid up for the winter, keep it on a maintenance charger. ### What is the service life of the MBT6N4 model? As a guide, you can expect the Motobatt MBT6N4 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 MBT6N4 model? Before buying, measure the space in your motorcycle: one extra millimetre can stop the hold-down clamp from closing. The Motobatt MBT6N4 takes up 71×71×96 mm (length, width and height, terminals included). ### Will the Motobatt MBT6N4 battery fit my motorcycle?
