Like a couple of previous posters I’m not a fan of battery tenders. Never used one. Never replaced a battery on any of the modern bikes I’ve had since 2000. JJH
Regardless of the battery maintainer. The bike ran perfectly 5 weeks ago on an all day ride. Is it normal for a battery to completely discharge on bike? With ignition off what kind of leakage would be expected. I have no sat nav or any other equipment fitted.
Or is 5 weeks unused normal to have to recharge?
