Laptop Battery Question !

[Waqas409]

So i have Li-on Battery in my laptop, its 1 and half year old i guess, couple of weeks ago it was dying i mean the full charge capacity was went down to 19800mWh, i turned on my laptop for continuously 3 days and it was on charge for the whole 3 days. so now the full charge capacity is going up again, it went from 19800mWh to 28500Mwh and now its 35740mWh and the battery timing is increased. So why its getting alive again? im scared this is kind of messup and will blow

not sure if this helps but, most laptops especially the mid-high end one have overcharge protection, i wouldnt be concerned if its a oem but aftermarket ones are hit and miss. what is stupid is most batteries have a recharge life of 500times which means less than 2 year life
