2019 250 EXCF, as standard the bike has a lithium battery. It looks like the present battery is cooked SO, is there a downside to fitting an ordinary lead acid battery at all ? (Apart from the weight !). cheers for any advice guys
Have you tried the 9v battery trick to see if it will charge (if it's flat and cannot take a charge - connect the terminals to a PP9 battery then put a charger on and leave for 5 mins, then disconnect the 9v battery)?
