  1. I was looking for a YTX20L-BS for my 2001 Yamaha Roadstar to get specs and testing methods, but you don’t seem to have it listed. As popular a battery as it is, why not?

    Also, is there a maintenance free version of it with identical dimensions? I bought the one above last year, and it cooks off the acid so I have to add distilled water and charge. My bike manual calls for a minimum output of 12.8 volts, unloaded, but I only get 12.43 after a couple hours on the charger.
