More and more we are tending to depend on our mobile technology when we are away from home and on the job. Cellphones, notebook computers and other battery-operated devices are becoming more and more prevalent. If you have ever had a battery run out on you, or if one has quit to charge, finding a replacement can be a problem. If you child has a PSP, having spare psp batteries can really help keep your kid entertained when you are on a long drive or away from home. Keeping the battery changed can be a challenge, have a fully charges spare or replacement battery is one way to keep them occupied. My very active 3 years old can sit for hours with her sister portable game device and that is my quiet time.
