Then there is the never ending saga about batteries.
There are 2 use modes that substantially shorten the life time/
capacity of a battery (holds for most battery chemistries, but
particularly Lead Acid)
- Deep discharge
- Over charge
Most common glider batteries (like the PowerSonic 7AH)

My experience has been that leaving one sit around in a discharged condition
will kill one permanently dead, just as quick as the other two reasons
listed above.
