How to Charge the Li-ion Sony VGN-FZ290N battery?
Claims of fast charging a Li-ion Sony VGN-FZ290N laptop battery
in one hour or less usually results in lower charge levels. Such a
charger simply eliminates stage two and goes directly into 'ready' once
the voltage threshold is reached at the end of stage one. The charge
level at this point is about 70%. The topping charge typically takes
twice as long as the initial charge.
Depending on the charger and the self discharge of the Sony VGN-FZ290N battery
a topping charge may be implemented once every 500 hours or 20 days.
Typically, the charge kicks in when the open terminal voltage drops to
4.05 volts per cell and turns off when it reaches 4.20V/cell.
No trickle charge is applied because the Li-ion laptop batteries
for Sony VGN-FZ290N laptop is unable to absorb overcharge. Trickle
charge could cause plating of metallic lithium, a condition that makes
the cell unstable. Instead, a brief topping charge is applied to
compensate for the small amount of self-discharge the Sony VGN-FZ290N
battery and its protective circuit consume.
