Discharge
- Dead discharge for years does not hurt the battery? [1]
Reconditioning
- It appears that carbonate crystals form on the electrodes, but these can be shaken off by draining electrolyte and filling with distilled water, then going through electrolysis which heats the water and gas bubbles shake the carbonates off [2]
Are they really good?
- Good jar experiment that one can try - [3] - mentions nickel (II) hydroxide and rust (Fe3O4 - Magnetite.)
- Comment from user - the Chinese versions suck - [4]
- P. II-27 says Lithium Hydroxide is used in small part in electrolyte [5]
- Cost of LiIon is down to $100/kwhr [6]
- Shit. Under deep discharge of 60-80%- Westinghouse is getting only 1600 cycles. So do they degrade like lead acid? Maybe not as bad, but nowhere near the 30 years of deep discharge. -II-28
Cost
- 3.2kg of nickel per 1 kwhr p. II-32 [7]
