Today an increasing rarity, that is, an electrolytic battery.... It was installed in a 250cc Quad in which it handles sensationally! Even now that it's winter, it's spinning well enough to be able to start without problems! And it also spins and spins.... Not like some cheaper especially gel ones, a few turns and the voltage drops. Just elegantly holds that voltage! As well as actually has that 9Ah capacity! I recommend!
