Art_H Posted November 17, 2005 Report Share Posted November 17, 2005 This looks like an amazing site, I just found it today.IBM T23 Li-ion battery. This battery will register as being fully charged, then when in use, 20 min in will immediately register 5% charge. The battery is getting tired, as all things eventually do. Right? Well, not wanting to pay the price of an all new pack, I looked into renewing the cells. Well after doing a little research on the Li-ion batts, ( from this great site, I might add) I found out that cell discharge stops @ 2.3v/cell via the "smart" tech in the pack. However, the per cell voltage in my "dead" pack is 3.96v. I watched the battery monitor on windows indicate the power drop, yet when my multimeter is showing 3.7v/cell under load with the laptop speakers playing music, I et 'kinda suspicious.What gives?Are the batts. toast? Or is it the circuit board? Or what...Any way I can easily test the batts. for health?Thanks for your help...Art Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 17, 2005 Report Share Posted November 17, 2005 Hi Art,Welcome to our forum. ;DIf the Windows voltage measurement is correct, then the battery's voltage detecting circuit is sick. Sometimes the battery's circuit is inside its package. Quote Link to comment Share on other sites More sharing options...
pseudoelf Posted March 17, 2006 Report Share Posted March 17, 2006 It may also be that the battery thinks it's wrong. Both of my laptops have PCB in the battery pack that need to be recalibrated from time to time. (Usually done from the bios not the OS) Quote Link to comment Share on other sites More sharing options...
