I have an Acer Travelmate 2300 (don't tell me about how old it is :) ) and the battery now lasts about 20 minutes on the lowest brightness setting doing stupid stuff like browsing the web.

I've really got nothing to loose with this battery, and i'm not investing in another one because ill hopefully be buying a Macbook Pro soon!

So, I've been reading on the web if i let the battery die (more like 20% charge), then put it in the fridge (not freezer, fridge is above freezing) overnight, then take it out in the morning and charge it fully, then let it die, then charge it fully, i might have a longer battery life.

I think im going to do this tonight, anyone have any ideas or suggestions? Anyone tried this before? If not, im going to be the first i guess :P .
 
okay well i put the battery in the fridge for about 6 hours, and i let it go back to room temperature

its now charging in my laptop, and everything looks good, so lets see what happens.

ill post back later.
 
no the freezer... you want it to be deep frozen. and it should be for about a day at least. then let it thaugh for 1 day. and it will be close to new...
 
Keep it in there for an week.

Only works on NiMH and NiCD though. Right after reviving place by some light, and let it come back to room temperature. Lithium Ion will not work, as I have tried.

Since your laptop is that old it is most definitely NiMH, and you should have an great chance or reviving it. Replacing cells would be an bit of an overkill, but could work.

Nope, it's a lithium ion, it says right on the battery. So if i put that in the freezer it won't do anything?

BTW the fridge did absolutley nothing.
 
I would no screw around with Lithium-Ion batteries, I am scared of those things. The will catch fire in a heartbeat due to overheating/acidity levels changing or overcharging. I have actually seen one in life catch on fire....
