Over time batteries will be come weaker and eventually will not provide enough power to operate the tool as it was designed. Several factors can cause this; normal deterioration of the battery, improper charging and the way the tool is used are the largest factors.

Batteries use chemicals and metals to create their electric charge. With use these elements breakdown and loose their effectiveness. Heat greatly accelerates the breakdown of the cells. When a battery pack is discharged quickly it creates more heat than normal use would create thus wearing out the battery pack faster. Charging a battery also creates heat. If a battery pack that is still warm is immediately placed on the charger even more heat will be created, shortening the life of the battery even more. Batteries should always be allowed to cool or heat to room temperature before charging.
