Why avoid third-party, generic tool batteries?

Knock-off tool batteries can be tempting to buy. The price of a generic can often be half or a third of the price of a manufacturers original battery. With the cost being significantly cheaper, what is the benefit of using original batteries?

1. Warranty coverage - Your tools warranty may be voided if anything happens to it, while using a third-party battery. Be sure to check your warranty coverage before you consider buying a knock-off.
2. Integrated technology - Batteries are becoming smarter. Newer batteries are integrating electronic components that allow them to communicate with devices they are plugged into. Some batteries provide usage data and prevent overcharging. Other batteries allow for daisy-chain usage, with multiple batteries communicating with each other to power larger wireless equipment.
