On this topic too the comments are contradictory.  One the one hand it says "Always try to keep the battery between 15°C and 25°C (59°F and 77°F)." while in the extending battery life section it says "Stay cool. Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator.".

Even disregarding the fact that storing in a battery is not a practical thing to do if you actually want to use it, a refrigerator is (or should be) a lot cooler than 15°C.

So again, which comment is correct?

[edit] Unattributed Quotes

The page contains an abundance of unattributed quotes. While I don't think we need to go Wikipedia-style "Citation Needed" happy in the maemo.org wiki, the sheer number of unattributed quotes in this particular article feels odd. Can anyone find sources for these quotes? --sjgadsby 13:13, 18 March 2009 (UTC)

[edit] Battery type

> The tablets use lithium-ion batteries

They actually use lithium polymer batteries (advantages and disadvantages), specifically the BP-5L (770, N800) and BP-4L (N810).

It's a wiki, feel free to fix it yourself. ;) Also, remember to sign your comments! ~~~~ GeneralAntilles 04:20, 26 March 2009 (UTC)

[edit] Deep-Cycling

I've never fully understood this, and the article is making it worse:

"discharge the battery from time to time by leaving the product switched on until it turns itself off." (which I think fits the definition of deep-cycling) vs. "Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries"

So, which one is true?


[edit] temperature

On this topic too the comments are contradictory. One the one hand it says "Always try to keep the battery between 15°C and 25°C (59°F and 77°F)." while in the extending battery life section it says "Stay cool. Li-ion batteries should be kept cool. Ideally they are stored in a refrigerator.".

Even disregarding the fact that storing in a battery is not a practical thing to do if you actually want to use it, a refrigerator is (or should be) a lot cooler than 15°C.

So again, which comment is correct?
