Interesting site, this link discusses the care and feeding of Lion batteries and includes some interesting info on shelf life, storage and capacity loss. Makes me rethink purchasing a “spare” battery. The site has other good info, for those information junkies out there…
I’m sure that this site has been mentioned before but I can’t seem to find it by searching!!
Thanks anyway for bringing it to the attention of all the new members as was a while ago it was last around.

Prob be a good addition to the FAQ. I’m new here and the only discussion of batteries I found discussed the tendancy of cheapo ebay specials to blow up. :evil:
This is why I did not buy the extended battery right away. I also put the TR into standby every night. This greatly reduces heat to the battery. For those of you who leave your TR on 24/7, be mindful that your battery will not last as long because of heat.
Great article, especially for all you battery geeks who have all that spare time to track your charge cycles. :wink:
BTW, not sure if this matters or not, but for years I’ve been putting my batteries (AA, AAA, C, D, etc) in the fridge instead of a draw like most people. I’ve found that if you keep them cold, they hold their charge, especially when I buy them in bulk at Sams Club.
Will it be a good idea to put my spare Lituim battery in the refridgerator? since the article says “...Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the battery at a 40% charge level…”
my concern is will my battery contacts to higher moisture in the fridge compare to outside living area?

That article seems to agree with your frigid theory. :wink:

I would be afraid to do it with an expensive battery…if the contacts get wet on my $.99 AA battery I just chuck it, but on one that gets used a lot i’d be afraid.
My cycle is just cold to hot, you’d be doing cold to hot to cold to hot, etc…then I could see the contacts rusting.
In all the years though, i’ve never needed to throw out a battery or a device because of contact issues…and i’ve never had a dead on arrival battery even when they were way past the experation date.

Good in theory, possibly dangerous in practice. Rapid cooling could cause condensation inside the battery (don’t know how much air is in there). The factor is relative humidity, not too bad here where RH is usually in the 40’s but in Florida…
My guess is that for long-term storage of a spare cell it’d prob work well. Over a relatively short time any moisture would ablate or evaporate. Upon removal there will be condensation on the outside and it should be dried and allowed to warm up and dry before stuffing it in the machine.
Of course you could just leave your laptop in the fridge and use it there.
Even employing all of these philosophies, what do we stand to gain? An extra couple of months out of the battery? Is it really worth all the effort? Even if you are careless, the battery should still last a couple of years. By then most of us will either just need another battery or upgrade to the next happy gadget. :D

Perhaps a moderate effort would be worthwhile? The problem is they don’t just die, they sneak up on you…
If you had a pair of batteries and used one only occasionally, it might not hurt to keep it in the fridge. If you often use a fixed physical location or run it overnight a lot, a cooler could make sense. One of the units with a USB hub would give you a mini-docking station.
Inversely, I’m certainly not going to travel with a cooler pad nor am I likely to take the battery off the machine when I’m running on line power.
