Bike's sealed battery is probably on its last legs[1] but I'm too pikey to go buy a new one atm. Is the desulfation mode on battery chargers/conditioners (I have the one from Lidl) any use in such cases, should I be looking at a different type of desulfator or just go buy a new battery? [1] Holds charge OK but drops significantly within less than 10 seconds of hitting the starter button[2] [2] Bike's unwilling to start lately - probably a combination of the weather and my decision to replace the broken choke cable "some other time".
