Have an 05 Honda Trike with Lehman Kit original battery lasted over 7 years and was replaced only because of age, never touched it with a charger or tender. New battery identical to the one taken out 2.5 years old would not start, it tried to start but all the lights pulled it down. I guess the new batteries are not as good as the old ones. Why didn't Honda put a switch in so you could start your bike before turning the lights on>> Cheap Cheap. Guess I need to get a tender from now on.
