By using the Amp-hour rating, you can determine the "size" of battery needed by multiplying the current [Amps] you need to do a job, and how long [in hours] you need that current to be supplied before having to recharge the battery.
One caution however, Amp-hour ratings are not always 100% accurate, and you must be prepared to recharge more often if the battery does not actually produce that much power.
This problem usually manifests itself when the power is drawn out of the battery in huge amounts/rates rapidly. When a battery is discharged at a very slow rate in relation to its capacity, then the Amp-hour ratings are usually very accurate.
Quite often by the USB plug on the speakers. If by non-powered you mean powered by batteries, then normally by the AV/headphone connection on your laptop.

simple. lets imagine you have a 70 Amp Hour battery (technically an accumulator, not a battery, but thats not important). the designation means it can sustain a 1 ampere continuous drain for 70 hours, or a 70 ampere drain for 1 hour. these figures are usually validated by certain temperature ranges etc,, hope this helps.
Don't understand what you mean by "exchangeable". Pretty much all batteries should be properly recycled. Best environmental choice is rechargeable batteries.
This dream suggests that the dreamer feels the need for energy. Batteries represent energy or power.
Panasonic does not manufacture batteries for older cameras any longer, however that does not mean the batteries can not be found. Online retailers such as Amazon still carry old batteries from sellers who no longer need them.
. What do you mean? What is they?
Yes, even a potato can light a light bulb. Yes. If the batteries match the voltage of the bulb, they can light it. Flashlights have bulbs and batteries that power them. If you mean a household light bulb, then you'd need many batteries in series (80 of the 1.5 volt batteries).
A formula does not normally have a mean!
It means there is a problem with the charging system.
If you mean who makes OEM batteries for Plymouth Roadrunner they are all labeled Mopar but are manufactured by several different companies
Also normally distributed.
