why can motorbike batteries sit on a shelf unused without losing charge but when sitting inside a motorbike for a few weeks that hasn’t been turned on, go dead?

In: Technology

When its on the shelf, there no where for the energy to go. In a motorbike, the battery is slowly and passively discharging. even if nothing is on. This is because the electrons in the battert have another place to go, the motor bike electrical system

Errr also. I’m not sure how much it’s changed. But most of the boxed batteries we got at the shop for the bikes still had no fluid mixture in them on the shelf.

Once we cracked open the box we put the water in and pushed on the seal and then it was ready to go.

This was about 10 years ago though.

There are two things:

First, some portions of your bike’s electrical systems will often remain on when the bike is turned off, causing minimal, but noticeable drain.

Second, on the shelf the battery is in a climate controlled environment, while in the bike it is not. Repeated heating and cooling causes many types of battery to lose charge, especially if it is outside of the battery’s ideal temperature range.
