Interesting Battery Article

[rrc1962]

I don't know if this has been posted before, but it's a pretty good article on Lithium Ion batteries.

Thanks, Ross. There's a wikipedia page on lithium ion batteries that looks like it's been lifted from this batteryuniversity.com web page. The tables and some of the advice have been posted in earlier threads.

Always good to have the original source. :)

Aloha,

Who do you think lifted from whom?

Seems pretty clear, if you do a Wikipedia search for "lithium ion batteries" and check the references:

Guidelines for prolonging Li-ion battery life

* Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a long time, they should be brought to a charge level of around 40% - 60%. Lithium-ion batteries should not be frequently fully discharged and recharged ("deep-cycled") like Ni-Cd batteries, but this is necessary after about every 30th recharge to recalibrate any external electronic "fuel gauge" (e.g. State Of Charge meter). This prevents the fuel gauge from showing an incorrect battery charge.[14]

Having said this, I hope this doesn't turn into a thread on the merits of Wikipedia. :rolleyes:
