Re: Jan 17 - Part 4. Extending Battery Lifetime

Jay-

On batery capacity that varies with drain rate- you are correct and it can be difficult to use manufacturers data (typically in graph form as you say) but it is possible to do some estimates that 'bound' the lifetime using these graphs. Not as accurate as you might wish, but should be accurate enough for most applications (you should be able to show that you can run for at leasy 2 years- for example- but may not be able to say exactly how much longer than 2 years).
