The question you seem to be posing is 'what is the energy density of different battery types'? Lithium (and variants) top the list. They are expensive, but last a long time, and hold pretty huge charge (by weight) Nickel Metal Hydride (NiMH) are next up, with reasonable performance, and unbeatable cost. Nickel Cadmium are awful for the environment, but thankfully recyclable. They offer better cold-weather performance to the above, but lower overall performance. They suffer from memory effect meaning they require a strict full-discharge regimen or they become unusable. (crystals form preventing current flow) Lead acid sits somewhere in there, I think at the bottom. Cheapest per watt by far, but heavy and some require maintenance. Google battery performance or battery types and you'll get scads of information.

depends on what it really is you want to learn... of it's something portable and inexpensive, use NIMH (buy these on Ebay) if it's something portable and expensive, use Li-ion, but you will need a special charger (look up Li-ion battery on google products) If it's something stationary, go with the Lead-Acid (look on craigslist, shipping them costs more then the battery does)

Search for "UPS batteries" and see if that helps to phrase the question towards what you want to know. L
