Laptop battery pack New. charged by computer 12.48v 4.16v per cell 5 amp hrs
Used battery 1 year 30 cycles. charged manually 13.85v 4.60v per cell 3 amp hrs
All the cells are within 0.03v of each other.
Had to charge the old one manually at 500 ma. the protection ckt in the battery pack shuts
the laptop charger down at 12.7v and says the battery is full.
QUESTION: Does the voltage of a Lithium Ion battery go up as it ages?
All the research I have done says if the voltage is above approx 3.2v the cells are good.
Looks to me like the protection ckt in the battery pack is set to sell battery's.
