How Long Does A Motorcycle Battery Last Without Starting. Lead acid batteries which are the most common in motorcycles can last between 2 and 4 months without charging. Expert Gear Advice From Riders.
A typical acid filled battery will last from 2-3 years but a 5 year lifespan is possible. If you have to run without the charging system then Id remove the starting system and rotor as well rather than carry the weight penalty. Months of it sitting plus those starts can very well kill a battery.
So every time you get on and go your battery is being charged.
If you are not riding your motorcycle every day and one of the best things you can do a lot of who battery is to purchase a battery tender sometimes also known as a battery saver. This is a question commonly asked in the months preceding winter when bikers often take a break. I tried to start my bike up the other day and I had the tender on it for a couple months so it should have a full charge but I tried to start it and it was completely dead. The estimated average lifespan of a motorcycle battery is about four years but there have been cases where a bike battery lasted for over eight years.
