Extending the life of your laptop battery – work with computer plugged in or drain+recharge your computer?

How much do lithium batteries size D weigh?
I'm doing a project that requires lithium D batteries and I need to know how much they weigh. Preferably in grams. I checked a Duracell NI-CAD D-cell, and it weighed 145 gr. Since a Lithium is a bit heavier, I'd guess they'd be about 200 gr.
Can I recharge rechargeable batteries in my digital camera using my computer while they are in the camera?

AC/DC Power adaptor?
I bought a new mp3 player. It came with a 5volt AC charger. the power input on the back says 5Volts DC. MY machinre is not working, is this why? yes, there is a difference between ac and dc current. ac can charge batteries, but not power dc equipment
2 batteries connected in series thru a resistor. What happens to current if ONE of the batteries is switched?
Two batteries connected in series through a resistor are bucking eachother. (Current and battery voltages given). If one of the batteries is switched (flipped), what is the new current? the flipped battery will be reversed in polarity, thus applying a backflow current! although i dunt really get ur question?
Can any universal ac adaptor be used on any laptop and can you do the same with a universal battery?
Not really. Ideally you should always use the supplier's battery and transformer I would error on the side of caution and say no. Your laptop is configured to receive DC power at a certain voltage level and current. While your universal AC adaptor may be able to provide the proper voltage level, it may not [...]
