Why lithium stock-ion battery? Because it provides high energy density, runtime, and is light in weight. To run a power-sucking laptop, a battery with high energy density is required. The runtime of a laptop battery is based on what sort of applications you run. If you run basic applications for writing, reading, copying, chatting, etc, then your laptop battery runtime will be high compared to running a complex application that has a huge number crunching requirement.

Grooming items are iffy but worth checking out. Shampoo is a decent find as are scrubbies/loofahs. Items like Chapstick and Vaseline can often be found there and my very favorite soap (Yardley oatmeal and almond) is almost always available at the dollar store. Nail files, packages of combs, tooth flossing sticks are of value. Skip the cotton swabs (too flimsy and could be dangerous), make-up (due to lack of regulation), and make-up remover pads (can I just say UGH!?).
