Wheelchairs and scooters normally use two identical batteries in series: replace them together. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 17 kg and M6 terminals. ### Will it fit your current battery tray? It has external dimensions of 226 × 135 × 214 mm and weighs 17 kg. It uses M6 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery. ### The Kronobat ES55-12: AGM Deep Cycle range and AGM technology The ES55-12 is part of the Kronobat **AGM Deep Cycle** 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. ### What Kronobat does differently Kronobat is the exclusive brand of baterias.com: batteries made to the same production standards as the leading brands, with a value for money that is hard to match and an official warranty.
