I bought a used 300 hpe sport here in London, UK
the previous owner hadn't had much use of it, and had it on a trickle charger.
It rode fine back home and again on another trip of c 2 miles.
I didnt ride for a week after, and the bike wouldn't start - dashboard showed c 10 volts.
I disconnected and charged up the battery, and the bike started fine. I checked the voltage at the terminals (with a multimeter) when running was c 14.5v which i presume means the stator works as well.
I left the bike for a couple days, and now it refuses to start again; 10.5 v on the dashboard.
Now, I presume I need a new battery. The one in the machine is YTZ14BS. The manual doesn't say a specific model, but its got a diagram with a yTX12BS in the picture. There is a specs table at the end that only says 12v with 10Ah.
So ... what battery do I need?
Also, I am just a bit concerned about parasitic leakage. Is there anything specific i should look at before ordering a battery?
