laptop batteries - too smart ?
Posted on 2013-02-05
i have had recently to replace 2 batteries for HP Pavilion laptops.
Since i enjoy learning and testing, i opened the battery packs for inspection.
one has the 18650 -2200mAh type cell of 3.7V; the other is more powerful.
Anyway; i was able to charge both battery assemblies, and tested they deliver up to 3 A, which should be enough for booting.
This brings me to my question :
Since the Batteries seem ok - it looks like the failure to boot up is due to the smart battery circuitry in each pack.
i do not believe both sircuits failed, but it is possible.
does anybody out there have the same experience ?
Or Is HP building a SMART circuit into the pack that disables the loading - or use of the pack?
very curious to see the reactions
