Does a battery go dead when the bike is parked?

Does a battery go dead when the bike is parked? Interesting question! Well I’ve been assigned a task for 10 days at Kangar, Perlis which is about 500 KM from Kuala Lumpur. I’ve decided to drive my car up north as I have quite numbers of luggage.

Whilst I was driving, I remembered that I’ve forgotten to take off the battery from its terminal! As others were suggesting, if you’re going to park your bike for quite some time, it is advisable that you remove the battery from its terminal as it could lead to few problems such as starting the bike after quite some time.

So after 10 days, I kept my finger crossed and calmly started off the bike and you know what? it starts perfectly without any problems!! I’ve then let the engine running for about 5 minutes so that it can warm up properly and off I go for my usual ride 🙂

So, how quickly does a battery go dead when the bike is parked?

Does a battery go dead when the bike is parked?

All batteries self-discharge at a rate of about 1 percent per day, but higher ambient temperatures accelerate the process. A battery stored at 95 degrees, for example, self-discharges twice as fast as one stored at 77 degrees.

Temperatures above 130 degrees can destroy a battery outright. Lower temperatures slow the self-discharge process, but don’t put your battery in the freezer quite yet. Pure water freezes at 32 degrees, but electrolyte won’t freeze until about minus 75 degrees. The more discharged the battery, the closer to water the electrolyte becomes, and the higher the temperatures at which it freezes. The electrolyte in a deeply discharged battery can freeze at only a few degrees below that of pure water.  Park your bike at a good room temperature for longer battery life.

On of our site visitor called Hylife also commented as per below:

“The lead dissolves into the sulphuric acid (H2SO4) forming lead sulfate (PBSO3) and H2O. Recharging deposits the lead back onto the plates reversing the chemical process and generating Hydrogen and Oxygen in the process if done at too high a rate which is why non-sealed batteries loose fluid and need to be topped up with distilled water.”
