Really work: Freeze trick to revive laptop battery

Just tried the freezer trick to revive my HP Dv5 laptop battery, it is really working so far. I follow the instruction online, wrap it with 3 layers of newspaper, put it into zip bag. 3 days in the freezer, 2 days in room temp with newspaper wrapped, 2 days in room temp without newspaper, and then recharge without switch on the laptop for 12 hours. Now it is showing 100% after 30 minutes, looks unreal, it was only able to hold 10 minutes max. Calibration doesn't work, so I decide to try this trick.

I will update the condition in 3 days.

• 沒戲，鋰電池一旦生產出來就開始退化，一年大概消失20%的儲量 -6sa7- ♂ (211 bytes) () 01/21/2010 postreply 18:42:38

• 實際退化比這要快得多吧，有多少電池能堅持三年？ -走萬裏路- ♂ (0 bytes) () 01/22/2010 postreply 06:04:46

• 好像把電池短路或反充（正負極顛倒）也頗有效果，不開玩笑！ -報社記者- ♂ (0 bytes) () 01/24/2010 postreply 06:30:46
