Input: This battery is the same one that came with my Toshiba NB305 netbook. Having a spare allows me to run the netbook at peak settings to speed things up, or extend the time I can use it when I'm away from a power source.<br /> I love having the extra battery available when I start to run low on power at an inconvenient time. I snap in the fresh battery when I need it and then put the dead one back in at night to charge it. In the morning I change back to the partially used one so I always have a fresh battery.<br /> This was worth every penny, and I feel like I got a great deal!

Great to have a spare
