Spreadsheet now published! Current batteries types with a mostly-filled page include LiFePO4, Li-SOCl2, & Li-Ion. Viewable @ https://docs.google.com/spreadsheet/...0E&output=html (designed for 1280x1024 monitor. Higher resolution results in wasted space. Lower resolution will cut off graphs. That'll be worked around when website is up.)

All data I publish, including the later website, will have no copyright restrictions, and I'll gladly accept BTC donations @ 14eT65cHTBJrRopzaoLu5nZEqcN5fhFKow or USD (CC, debit, Paypal) @ http://kludge.chipin.com/battery-testing
Donation Targets:
$0: Website designed & hosted. Non-rechargeable batteries tested at least once, rechargeables tested 5x. Spreadsheet & PPT released publicly with no copyright restrictions. Only one meter will be used, keeping testing pretty slow.
$50: All non-rechargeable batteries will be tested at least twice (uncommon batteries can cost upward of $5 each after shipping)
$250: All non-rechargeable batteries will be tested at least 5 times. Will purchase an adjustable power supply which will allow me to further research what voltages and currents are safe in different batteries. Many primary batteries may be safely rechargeable if a safe and practical charging rate is found. This also allows me more control in charging rechargeable batteries, permitting maximum accuracy. If I can find a reasonably-priced adj. PSU which accepts and transforms low DC currents, this will allow me even more control to ensure results are accurate and to safely test batteries using the multimeter.
$1000: All non-rechargeable and rechargeable batteries will be tested at least 10 times, with different brands used (to help ensure differences between manufacturing processes are accounted for). I can definitely purchase a more suitable meter at this price, and will do so if I can't find a corporate sponsor willing to toss me an old freebie from their R&D dep't.
$1500: At least 20 tests of all non-rechargeable and rechargeable AA battery types I'm aware of, with greater brand diversity, allowing critiques of manufacturers as well as battery types.
$2500: I'll test all AA batteries of all major battery manufacturers of all listed battery types I can find.
All donors will be listed in documents relevant to this project unless requested otherwise.
