 |
|
I read a useful article on Gizmode on li-ion batteries. Thought I�d share it with you. Here are the tips (sounds simple, but I don�t comply with them!) See link for full article.
� Do not let it run out completely all the time. Full discharge puts a lot of strain on the battery
� Do not keep a Li-ion battery fully charged all the time, either. If you don't use your battery it might suffer from capacity loss
� Keep your battery in cooler temperatures. Hot hot heat is not good for it
� If you're gonna store your battery, leave 40%-50% charge in and store it in a cool place (i.e. fridge).

Cheers. This kind of stuff is good to know.
Doesn't the moisture in fridges affect the battery? |

The idea is that you put it in a sealed bag, though it doesn't really matter that much. Incidentally, when you get a new phone with a spare battery it pays to use one exclusively and keep the other in the fridge. Li-ion batteries lose capacity related to the storage temperature and average state of charge. A 60% charged battery stored in the fridge will still have about 85%-90% of its new capacity after 3 years, while the one you've been using will be pretty much toast. |

| Some interesting stuff here, but I wonder if it's realy worth all of the trouble. I bought an extra battery for my Galaxy S recently for 15,000 won, hardly a huge expense. I think I would rather keep it fully charged and use the battery in whatever way happens to be convenient and just buy another battery next year if the capacity starts going down. I suppose laptop batteries may be more expensive, but still seems like a waste of time to me. With the rate that we upgrade and replace tech products these days you may be ready to buy a new laptop/phone/mp3 player/whatever by the time the battery starts dying. |

| Interesting about the fridge, I suppose it's different technology from car batteries which hate the cold. I went on vacation last year, and left my laptop battery connected to the laptop which was off. I returned after a month in August and the battery was kaput; wish I'd taken better care of it. |

Acid batteries actually prefer the cold too. We're talking 40 degrees F here, not sub freezing temperatures. I remember growing up when on e of my friends parents stored old alkaline batteries in the fridge to "charge" them. It worked a little (not worth the time or space commitment). |
