Faulty battery monitor?
If it's a NiCad, consistant recharging when the cell isn't discharged to the recommended "discharged" voltage can cause what is
known as "memory effect", where the battery will never charge above that partially-discharged state at which it been consistantly
recharged from. Also, if a NiCad is allowed to discharge below a certain voltage, polarity reversal can happen. Most modern gear
will use NiMH or Li-ion cells nowadays, because such cells do not have these problems. Some manufacturers using cheezy parts and
other cut corners in quality do still use NiCad cells though [if they were shoddy there, where else were they shoddy?]
Main question: is it under warranty?
