I got a question regarding batteries. In winter when I don’t ride my motorcycle, my battery drains bit by bit and if I don’t charge it, it’s dead after a few months.
What happens if I disconnect it and take it out? Does the battery still drain, but less? Does it not drain at all?
In: Engineering
A lead-acid battery will have a slow intrinsic self-discharge rate, even when it’s not connected to anything. It happens because of the internal chemistry.
So it has to be maintained with a proper charger, if it’s left for many months. If the battery sits around with a partial discharge, the internal chemistry causes irreversible sulfation of the plates. That lowers the battery’s capacity & max output current. Degraded plates can later lead to rapid self-discharge & even dead cells.
